Top Industrial Shed Manufacturers in Pakistan:
1. What Is an Industrial Shed? (Open Shed, Closed Shed, Covered Building)
An industrial shed is a steel‑framed structure designed for industrial, commercial, or agricultural use. Based on enclosure, industrial sheds are classified as:
| Type | Description | Typical applications |
|---|---|---|
| Open shed | Only roof and columns; no walls | Car parking, machinery storage, canopies |
| Semi‑closed shed | Roof + partial walls (e.g., 4‑ft brick dado) | Dairy sheds, poultry farms, workshops |
| Closed shed (covered building) | Fully enclosed (roof + walls on all sides) | Factories, warehouses, cold storage, showrooms |
Silver Steel Mills manufactures all three types, customised to your specific requirements.

Engineering High-Performance Pre-Engineered Buildings (PEBs)
Why BOQ is the Backbone of Every Construction Project
In the construction industry, whether you work for a contractor, client, project management consultancy (PMC), or a vendor, understanding the Bill of Quantities (BOQ) is not optional – it is essential. A BOQ defines the scope, quantifies materials and labour, and provides the basis for cost estimation, tendering, and project execution. Yet, many engineers struggle with preparing, reading, and analysing BOQs – especially for pre‑engineered buildings (PEBs), which have unique components and terminology.
This article is based on real‑world experience and industry standards. It explains:
-
What a BOQ is and its different formats (item‑rate, percentage‑based, lump sum).
-
How to read and create BOQs for civil, structural, and PEB works.
-
The complete component list of a pre‑engineered steel building – from primary frames to accessories.
-
Practical tips for accurate estimation and tendering.
By the end, you will have a solid understanding of BOQ preparation and PEB anatomy, enabling you to confidently handle tenders, estimate costs, and communicate with clients and vendors.
Section 1: Understanding Bill of Quantities (BOQ)
1.1 What is a BOQ?
A Bill of Quantities (BOQ) is a document that lists all the items of work, materials, and labour required for a construction project, along with their quantities, units, and agreed or estimated rates. It serves as a tender document, a contract schedule, and a basis for progress payments.
1.2 Types of BOQs Commonly Used in Pakistan
| Type | Description | Typical Application |
|---|---|---|
| Item‑rate BOQ | Each work item has a description, unit, quantity, and rate. Total cost = sum of quantity × rate. | Government tenders (e.g., PWD, NHA), private contracts with detailed scope. |
| Percentage‑rate BOQ | A base rate schedule is provided; bidders quote a percentage above or below (e.g., +10% or –15%). | Renovation works, maintenance contracts, where exact quantities are uncertain. |
| Lump‑sum BOQ | A single price for the entire scope; often used with a schedule of items but no breakdown of quantities. | Small projects, turnkey contracts, supply of materials (e.g., PCC poles). |
| Labour‑only BOQ | Only labour items listed; materials are supplied by the client. | Labour contracts for construction or maintenance. |
| Material‑only BOQ | Only material supply items listed. | Procurement of steel, cement, panels, etc. |
1.3 Anatomy of an Item‑Rate BOQ (Real Example)
A typical item‑rate BOQ includes:
-
Project details – Client name, project name, project number, consultant name, estimated cost.
-
Serial number (Sr. No.)
-
SOR (Schedule of Rates) reference number – Code from government SOR (e.g., 2.28.1 for surface dressing).
-
Description of item – Taken verbatim from SOR or custom written for non‑standard work.
-
Unit – Sq. m, Cu. m, Kg, Nos., etc.
-
Quantity – As per site measurements or drawings.
-
Rate (Rs.) – Unit rate as per DSR or market analysis.
-
Total amount (Rs.) – Quantity × Rate.
Example line item (Surface Dressing):
| Sr. No. | SOR Ref. | Description | Unit | Quantity | Rate (Rs.) | Amount (Rs.) |
|---|---|---|---|---|---|---|
| 1 | 2.28.1 | Surface dressing including removal of vegetation | sq. m | 162.00 | 17.45 | 2,839.00 |
| 2 | 2.6.1 | Earthwork excavation | cu. m | 250.00 | 169.65 | 42,412.50 |
Note: When you have to quote a lower or higher price, you analyse the rate and then modify the unit rate accordingly. For percentage‑based BOQ, you simply enter a percentage (e.g., –15%) and the system calculates the discounted total.
1.4 How to Prepare a BOQ – Practical Steps
-
Study tender documents and drawings – Understand scope, specifications, and SOR.
-
Take off quantities – Calculate lengths, areas, volumes from drawings.
-
Identify work items – List each distinct activity (excavation, concrete, steel, painting, etc.).
-
Assign units – Use standard units consistent with SOR or industry practice.
-
Enter quantities – Be accurate; double‑check take‑offs.
-
Analyse rates – Use DSR (Delhi Schedule of Rates) or local PWD schedule; for market rates, do a material+labour+plant+overheads analysis.
-
Compute totals – Sum up to get the estimated cost.
Pro tip: Always leave a contingency (usually 3‑5%) for omissions and price escalation.
Section 2: Components of a Pre‑Engineered Building (PEB)
Pre‑engineered steel buildings are widely used for factories, warehouses, dairy sheds, aircraft hangars, metro stations, stadiums, and even cold storage. Unlike conventional RCC construction, a PEB is an assembly of prefabricated steel components that are bolted or welded together.
The components can be divided into four main categories:
-
Primary Framing
-
Secondary Framing
-
Cladding (Sheeting & Insulation)
-
Accessories
We explain each with real visual references.
2.1 Primary Framing – The Backbone
| Component | Description | Typical Section |
|---|---|---|
| Columns | Vertical members that transfer loads to the foundation. Made of built‑up I‑sections or hot‑rolled I‑beams. | Tapered or prismatic welded plate section. |
| Rafters | Horizontal/sloping members spanning between columns, forming the roof slope. | Built‑up I‑section, designed as per bending moment diagram. |
| Base plate & anchor bolts | Steel plate welded at column base; anchored to concrete footing via anchor bolts (L‑type or J‑type). | Base plate thickness 20‑40 mm; anchor bolts grade 8.8. |
Connection details:
-
Columns are fixed to foundation using base plates and anchor bolts.
-
Rafters are bolted to columns using splice plates (end plates with high‑strength bolts).
2.2 Secondary Framing – Support and Stability
| Component | Description | Role |
|---|---|---|
| Purlins | Cold‑formed C or Z sections placed over rafters (roof) and over columns (wall). | Support roof/wall sheeting; transfer wind and snow loads to primary frame. |
| Girts | Same as purlins but used on sidewalls. | Lateral support for wall panels. |
| Sag rods | Round steel rods connecting purlins or girts at mid‑span. | Prevent purlins from twisting under load; resist lateral forces. |
| Bracing (Rod/Cross bracing) | Tension members (round bars or angles) in walls and roof. | Maintain structural stability against wind and seismic forces; keep building square. |
| Eave strut | A combination of a purlin and a girt placed at the eave (junction of roof and wall). | Provides support for roof and wall sheeting at the eave line. |
| Cleats (Clip angles) | Small steel angles used to connect purlins/girts to the main frame. | Easy alignment and bolted connections. |
Practical note: Purlins are typically Z‑shaped for roof (can lap over rafter) and C‑shaped for walls. Thickness ranges from 1.5 mm to 3 mm. Length up to 12 meters; for longer spans, they are spliced with cleats.
2.3 Cladding – Roof and Wall Sheeting
| Component | Description |
|---|---|
| Roof sheeting | Profiled steel sheets (trapezoidal or corrugated) screwed to purlins. Common materials: GI, PPGI, UPVC, or sandwich panels. |
| Wall sheeting | Similar to roof sheeting; installed vertically or horizontally. |
| Insulation | Fibreglass batts (compression) or rigid board (PIR/PU) placed between sheeting and structure. Sandwich panels (EPS/PU) provide integrated insulation. |
Why cladding is critical: Without proper roof and wall sheeting, the building is exposed to rain, wind, dust, and sun – leading to rust, discomfort, and reduced life span.
2.4 Accessories – Completing the Building
| Accessory | Function |
|---|---|
| Sliding doors / Roll‑up shutters | Large openings for vehicle/machinery entry. |
| Insulated windows | Allow natural light and ventilation while maintaining thermal efficiency. |
| Louvers | Fixed or adjustable slats for cross‑ventilation. |
| Ridge ventilators | Continuous opening at roof ridge to release hot air. |
| Turbo ventilators | Wind‑driven exhaust fans to extract hot air naturally. |
| Roof skylights (translucent sheets) | Natural daylight to reduce electricity bills. |
| Flashings & trims | Corner trims, eave trims, rake trims – provide weather sealing and aesthetic finish. |
| Gutters & downpipes | Drain rainwater from roof to ground. |
Section 3: BOQ Preparation for a PEB Project – A Step‑by‑Step Guide
When preparing a BOQ for a PEB, you must include all components listed above. A typical BOQ for a PEB warehouse would have sections like:
-
Civil works – Foundation, anchor bolts, flooring, drainage.
-
Primary steel structure – Columns, rafters, base plates, splice plates.
-
Secondary steel – Purlins, girts, sag rods, bracing, eave struts, cleats.
-
Cladding – Roof sheets, wall sheets, insulation, flashings, trims.
-
Accessories – Doors, windows, louvers, ventilators, skylights.
-
Finishing & painting – Primer and top coat (if not supplied galvanised).
3.1 Example BOQ Line Items (PEB Warehouse)
| Sr. | Description | Unit | Quantity |
|---|---|---|---|
| 1 | Supply and fabrication of built‑up columns (Q345B) including welding, as per drawing | MT | 12.5 |

| 10 | Turbo ventilators (14 inch) | Nos. | 8 |
| 11 | Sliding door (4.5 m × 4.5 m, insulated) | Nos. | 2 |
| 12 | Base plates & anchor bolts (grade 8.8) | Set | 24 |
3.2 Rate Analysis Considerations
-
Material cost – Market price of steel, sheets, insulation, etc.
-
Fabrication cost – Cutting, welding, drilling, shot blasting, painting.
-
Transport – To site.
-
Erection – Crane, labour, tools.
-
Overheads & profit – Typically 10‑15%.
For a realistic rate, refer to current PEB supplier quotes (like Silver Steel Mills) or government schedule of rates (where applicable).
1. Built‑Up Sections – The Backbone of Your Primary Structure
1.1 What Is a Built‑Up Section?
A built‑up section is a structural member made by combining multiple steel plates (or shapes) and welding them together to form a single, custom‑engineered section. Unlike standard hot‑rolled profiles that come in fixed sizes, built‑up sections are fabricated to meet the exact load requirements of your project.
Common built‑up shapes:
-
I‑sections (similar to I‑beams) – for columns and rafters.
-
Box sections – for high torsional strength.
-
T‑sections – for secondary members.
“A built‑up section is like a tailor‑made suit – it fits your project’s exact dimensions and load demands, unlike off‑the‑shelf sections.” – Silver Steel Mills engineering team.
1.2 How Built‑Up Sections Are Fabricated
-
Cutting – Individual steel plates are cut to required sizes (CNC plasma or shearing).
-
Positioning – Plates are aligned in the desired shape (e.g., I‑shape).
-
Welding – Automated or manual welding joins the plates continuously.
-
Inspection – Weld quality checked; dimensional tolerances verified.
1.3 Key Features of Built‑Up Sections
| Feature | Practical Benefit |
|---|---|
| Customisation | Depth, flange width, web thickness can be tailored to the bending moment diagram. |
| Material optimisation | Thicker plates used in high‑stress zones (e.g., mid‑span of a rafter); thinner plates in low‑stress areas → saves steel. |
| Welded integrity | Continuous weld ensures a strong, unified member. |
| Versatility | Any shape or size possible – ideal for long‑span PEBs (up to 50 m). |
1.4 Where Are Built‑Up Sections Used in a PEB?
| Component | Typical Section |
|---|---|
| Main columns | Built‑up I‑section (tapered or prismatic) |
| Rafters (roof beams) | Tapered built‑up I‑section (optimised for bending moment) |
| Crane beams | Heavy built‑up box or I‑section |
| End wall columns | Built‑up I‑section or channels |
Silver Steel Mills designs and fabricates built‑up sections in‑house, using Q235B or Q345B steel plates. All welds are performed by certified welders and inspected for structural integrity.
2. Hot Rolled Steel – The Standard for Simplicity and Economy
2.1 What Is Hot Rolled Steel?
Hot rolled steel is produced by heating steel above its recrystallisation temperature (typically 926 °C / 1700 °F), then passing it through large rollers to achieve the desired shape. The steel remains hot and malleable throughout the process, then cools naturally at room temperature.
2.2 The Hot Rolling Process
-
Heating – Steel billets or slabs are heated above the recrystallisation point.
-
Rolling – The hot steel passes through multiple roller stands to reduce thickness and shape it (e.g., into I‑beams, channels, angles).
-
Cooling – The finished section is left to cool in air. As it cools, it contracts slightly, which can cause minor warping or residual stresses.
2.3 Key Characteristics of Hot Rolled Steel
| Property | Description |
|---|---|
| Surface finish | Rough, scaly (mill scale) – not smooth. |
| Dimensional accuracy | Looser tolerances (± few mm) – not suitable for precision parts. |
| Strength | Good yield strength, but lower than cold rolled (typically 250‑350 MPa). |
| Ductility | High – can deform significantly before fracture. |
| Cost | Lower than cold rolled (simpler process, no additional steps). |
2.4 Common Hot Rolled Products in PEBs
| Product | Example |
|---|---|
| I‑beams / H‑beams | Secondary columns, primary frames (small spans) |
| Channels (C‑shapes) | Girts, purlins (sometimes) |
| Angles (L‑shapes) | Bracing, connections |
| Flat bars & plates | Base plates, gusset plates, stiffeners |
When to use: For standard sections where high precision is not critical, and cost is a primary concern.
3. Cold Rolled Steel – Precision and High Strength
3.1 What Is Cold Rolled Steel?
Cold rolled steel starts as hot rolled steel that has already been cooled. It is then re‑rolled at room temperature through additional rollers to achieve tighter tolerances, a smoother surface, and increased strength.
Sometimes, an annealing (heat treatment) step follows to relieve internal stresses introduced during cold rolling.
3.2 The Cold Rolling Process
-
Pickling (optional) – Removes mill scale from hot rolled steel.
-
Cold rolling – The steel is passed through rollers at room temperature, reducing thickness and work‑hardening the material.
-
Annealing (sometimes) – Controlled heating and slow cooling to remove residual stresses.
-
Finishing – Surface may be oiled to prevent rust.
3.3 Key Characteristics of Cold Rolled Steel
| Property | Description |
|---|---|
| Surface finish | Smooth, polished, often oiled – excellent for painting. |
| Dimensional accuracy | Very tight tolerances (e.g., ± 0.1 mm) – ideal for precision parts. |
| Strength | Higher yield strength than hot rolled (work‑hardening). |
| Ductility | Lower than hot rolled – more brittle. |
| Cost | Higher (additional processing). |
3.4 Common Cold Rolled Products in PEBs
| Product | Typical Use |
|---|---|
| Z‑purlins | Roof purlins (cold formed, high strength‑to‑weight ratio). |
| C‑girts | Wall girts. |
| Cee‑channels | Framed openings (doors, windows). |
| Trim and flashing | Corner trims, eave trims, ridge caps. |
| Steel studs | Interior partitions (if required). |
When to use: For secondary members where precision, smooth finish, and high strength are needed, or where weight saving is critical (e.g., long‑span purlins).
4. Comparison: Built‑Up, Hot Rolled & Cold Rolled Steel
| Parameter | Built‑Up Section | Hot Rolled | Cold Rolled |
|---|---|---|---|
| Manufacturing | Welded from plates | Heated above recrystallisation, rolled, cooled | Hot rolled + additional rolling at room temp |
| Surface finish | Smooth (if ground) | Rough, scaly | Smooth, polished |
| Dimensional accuracy | Very high (custom) | Loose tolerances | Very tight |
| Yield strength | As per plate grade (e.g., 345 MPa) | Lower (~250‑350 MPa) | Higher (work‑hardened) |
| Ductility | Good | High | Lower |
| Cost per ton | Medium (labour for welding) | Lowest | Higher |
| Typical PEB use | Primary frames (columns, rafters) | Heavy sections, base plates, angles | Purlins, girts, trims, cold‑formed sections |
| Lead time | Custom fabrication (3‑6 weeks) | Readily available (stock) | Available but may require rolling schedule |
5. Practical Recommendations for Pakistan’s Conditions
5.1 For Primary Structure (Columns & Rafters)
-
Use built‑up sections when spans exceed 20 m or when loads are high (e.g., crane‑supported buildings). Built‑up sections allow material optimisation per bending moment diagram – thicker flanges at mid‑span, thinner at ends.
-
Use hot rolled I‑beams for smaller spans (≤ 20 m) where stock sections meet load requirements and cost is critical.
5.2 For Secondary Members (Purlins, Girts, Bracing)
-
Always use cold rolled Z‑purlins and C‑girts for roofs and walls. Their higher strength‑to‑weight ratio allows wider spacing, reducing the number of frames and overall steel tonnage.
-
Galvanised cold rolled sections are preferred for corrosion resistance, especially in coastal areas (Karachi, Gwadar).
5.3 For Connections and Accessories
-
Use hot rolled angles and plates for bracing and base plates – they are economical and readily available.
-
Use cold rolled trims and flashings for a neat, professional finish.
5.4 Example: Standard PEB Warehouse in Lahore
| Component | Steel Type | Reason |
|---|---|---|
| Main columns | Built‑up tapered I‑section | Optimise steel for bending moment |
| Rafters | Built‑up tapered I‑section | Same |
| Roof purlins | Cold rolled Z‑purlin (galvanised) | High strength, light weight, corrosion resistance |
| Wall girts | Cold rolled C‑girt | Same |
| Base plates | Hot rolled plate (Q345B) | Economical, easy to weld |
| Bracing rods | Hot rolled round bar | Simple, low cost |

7. Frequently Asked Questions (Based on Real Customer Queries)
Q1: Can I use only hot rolled sections for a large PEB?
A: For small buildings (≤ 20 m span), yes. For larger spans, built‑up sections are more economical because they optimise material – you would waste steel using constant‑depth hot rolled beams.
Q2: Why are purlins always cold rolled and not hot rolled?
A: Cold rolled Z‑purlins have a higher strength‑to‑weight ratio, meaning you can space them further apart (e.g., 1.5 m instead of 1 m). This reduces the number of purlins and frames, saving overall steel tonnage.
Q3: Is cold rolled steel more rust‑resistant?
A: Not inherently. However, cold rolled sections are often supplied galvanised, which provides excellent corrosion protection. We recommend galvanised purlins and girts for dairy sheds, poultry farms, and coastal areas.
Q4: How do I know which steel type to order?
A: Our project managers will calculate loads based on your building size, location, and intended use. We then specify built‑up sections for primary frames, cold rolled for secondary members, and hot rolled for accessories.
Q5: Does cold rolling affect weldability?
A: Cold rolled steel can be welded, but the higher carbon equivalent may require pre‑heating for thicker sections. For typical purlins (1.5 mm – 3 mm), standard welding is fine.

Google ke ranking systems comprehensive technical parameters ko crawl karte hain. Hamari structural design check loops niche diye gaye safety standards ke mutabiq verify kiye jate hain:
A. Bureau of Indian Standards (BIS) & Regional Compliance Codes
-
IS 800:2007 (General Construction in Steel): Core baseline framework jo limit state design method ke mutabiq steel members ki structural strength, tension, compression, aur buckling parameters ko govern karta hai.
-
IS 875 (Part 3): Wind Load Calculations: Pakistan bhar mein dynamic environmental wind velocities badal rahi hain (Karachi coastal belt se lekar Northern regions tak). Is code ke parameters wind pressure distribution, topography factor ($k_3$), aur structural design wind speed ($V_z$) calculate karne ke liye utilize hote hain.
-
IS 1893 (Part 1 & Part 4): Seismic Analysis: Industrial structures aur heavy-load processing sectors ko earthquake shocks aur dynamic tectonic vibrations se safe rakhne ke liye precise dynamic analysis apply kiya jata hai.
B. International Standards & Advisory Guidelines
-
AISC (American Institute of Steel Construction): Allowable Strength Design (ASD) aur Load and Resistance Factor Design (LRFD) standard codes ke structural cross-sections ko design karne ke liye guidelines.
-
MBMA (Metal Building Manufacturers Association): Standard load combinations, crane operations parameters, aur initial framing geometric tolerances ko properly evaluate karne ke liye direct handbook references.

🛠️ 4. Civil Foundation Mechanics & Anchor Bolt Precision
PEB steel structures ka poora load final reaction force ban kar unke base plate anchor connections par transfer hota hai. Foundation work concrete parameters locations ke mutabiq modify hote hain.

Anchor Bolt Alignment Engineering:
Main clear-span frames ko secure karne ke liye structural columns standard $3/4\text{-inch}$ ya large frameworks ke liye $1\text{-inch}$ high-tensile anchor bolts utilize karte hain. Yeh anchor assembly column i-beam web center line se exactly $1.5\text{-inches}$ horizontal alignment par divide hoti hai, jisse do consecutive anchor paths ke darmiyan exact 3-inch spacing design ki jati hai.
Civil foundation pouring ke waqt automated high-frequency long-probe internal vibrators aur dynamic external reinforcement hammers ka ek sath use kiya jata hai taake pour matrix ke andar se hidden air bubbles aur structural spaces mukammal purge kiye ja sakein.
📐 5. Structural Levels Verification (Z-Axis Elevation)
Primary columns erection se pehle, structural layout ke complete leveling index ko automatic transits ya precise industrial laser levels se track kiya jata hai.
Elevation Delta (ΔZ) = High Pad Reading - Low Pad Reading
Agar total structural delta variance $\mathbf{1/8\text{-inch}}$ se $\mathbf{3/1\text{-inch}}$ ke darmiyan ho, toh installation acceptable hoti hai. Agar deviation limits isse barhein, toh variable high-strength structural base plates Shims (ranging from $1/8\text{-inch}$ to $3/4\text{-inch}$ thickness) placement karke exact dead-level surface achieve ki jati hai. Level mapping ko bypass karne se downstream roof sheeting lines mein severe distortions, abnormal panel bulging, aur expansion trim sagging issues peda hote hain.
⚡ 6. Integration of AI (Artificial Intelligence) & BIM in PEB
Modern steel fabrication lines mechanical precision badhane ke liye BIM (Building Information Modeling) aur AI (Artificial Intelligence) optimization loops use karti hain.
AI data analytics model structure ki safety integrity matrix ko processing speed faraham karta hai. Yeh initial stages par hi geometric profile errors, potential multi-axis connection clashes, aur execution inconsistencies ko accurately predict aur bypass kar deta hai. Is advanced integration se raw material waste percentages minimized ho jati hain, structural calculations hyper-optimized ho jati hain, aur onsite erection phases smoother aur error-free chalte hain.

(Deflects Solar Heat & Storm Moisture) (100% Rust-Proof Core) (Primary Structural Support)
High-Tensile Structural I-Beams
Our main columns and roof rafters are fabricated from high-strength structural I-Beams and built-up sections. These primary framing members are engineered using advanced 3D structural analysis software to transfer vertical dead loads, equipment weights, and horizontal wind pressures safely to the concrete foundations.
Rust-Free Galvanized Z-Purlins & C-Channels
For secondary roof and wall framing, we use cold-formed galvanized Z-Purlins. Because these secondary members are hot-dip zinc coated, they remain completely rust-free ($100\%$ corrosion protection) even when exposed to high industrial humidity, chemical fumes, or agricultural environments. This eliminates the need for frequent, expensive repainting.
Premium PPGI & PPGL Cladding Sheets
Our sheds are enclosed using high-grade Pre-Painted Galvanized Iron (PPGI) or Pre-Painted Galvalume (PPGL) steel profiles. Available in single-skin corrugated iron sheets or double-skin insulated sandwich panels, these coatings protect your facility from the elements. The outer paint layer reflects intense solar radiation, lowering interior building temperatures during peak summer months and reducing commercial HVAC costs.
