Industrial Roofing Sheets for Factory & Warehouse Roofs

Industrial roofing sheets are profiled steel sheets - corrugated or trapezoidal in shape - used as the outer roof covering on factory, warehouse, and shed structures. City Steel supplies industrial roofing sheets cut and coated to your roof plan, so your building sheds rain and stays cool without leaks at the laps or fastener points.

You get a coating built for Bangladesh's rain and salt-air exposure, a profile depth matched to your roof pitch and purlin spacing, and consistent sheet length so laps sit flush across the whole roof. Every sheet is roll-formed and cut to order at our Hemayatpur, Savar factory before dispatch.

Industrial roofing sheets fit garments and textile factory sheds, poultry and cold-storage buildings, and warehouse roofs for industrial developers across Dhaka, Gazipur, and Chittagong.

Why Choose City Steel Industrial Roofing Sheets?

Sheds Rain Fast Even on Low-Pitch Roofs

The trapezoidal profile channels water off the roof quickly, so a low-slope factory shed stays dry without needing a steeper, more expensive roof structure.

Galvanized or Galvalume Coating Resists Rust

Coating protects the steel core from corrosion in humid and rainy conditions. We help you pick hot-dip galvanized or Galvalume based on how close your site is to salt air or chemical fumes.

Color-Coated Options Cut Roof Surface Heat

A color-coated finish reflects more heat than bare galvanized sheet, which keeps factory floor temperature lower — useful for garments and poultry buildings with heat-sensitive processes.

Insulated Roof Sheet Cuts Noise and Heat Together

For buildings where rain noise or heat gain is a bigger concern, an insulated sandwich-panel roof sheet adds a foam core between two steel skins.

Consistent Profile for a Tight, Leak-Resistant Lap

Sheets are cut to matching length and profile depth, so side and end laps sit flush and fastener points line up — fewer leak points across the roof.

Cut and Coated to Your Exact Roof Plan

Profile depth, sheet length, and coating type are set from your roof drawing, not sold off a fixed catalogue size.

Faster Roof Closure than Waiting on RCC Slab Work

Sheets go up directly on the purlin grid, so your building gets weatherproof faster than a cast concrete roof needs to cure.

Profile depth and thickness are decided by your purlin spacing, roof pitch, and local wind load - a shallower profile needs closer purlin spacing to stay flat under wind uplift. Coating grade decides how long the sheet resists rust and fading in your site's weather. Exact specs are set from your roof drawing -

Is This Roofing Sheet Right for Your Project?

Industrial roofing sheets fit single-storey factory sheds, warehouse roofs, and poultry or cold-storage buildings where the roof structure is already sized by a purlin and rafter design.

They're the right choice for garments and textile factories, poultry farms, cold storage units, and warehouse developers building in Dhaka, Gazipur, Narayanganj, Savar, and Chittagong. Contractors on tight construction timelines also choose roof sheet over a cast concrete roof to save weeks on site.

Steel roof sheet beats RCC roofing on installation speed and roof dead weight, which lets a lighter, cheaper steel frame carry the roof.

Not ideal for: roofs needing a permanent concrete deck for rooftop equipment or heavy foot traffic - ask us and we'll point you to the right product.

How City Steel Fabricates, Delivers & Erects Your Roofing Sheet

We roll-form your roofing sheet from your approved roof drawing, confirm profile depth and coating type, then cut sheets to length at our Hemayatpur, Savar factory. You send us your roof plan with purlin spacing and pitch, and we confirm profile and thickness before production starts.

We deliver to project sites across Dhaka and nationwide. Our erection crews can also fix the sheets on-site, fastened to your purlin grid in the lap sequence set by your drawing.

Practical tip: confirm your roof pitch and wind zone early - both affect which profile depth and fastener spacing keep the roof secure.

Frequently Asked Questions for Industrial Roofing Sheets

What are industrial roofing sheets used for?

They're profiled steel sheets used as the outer roof covering on factory, warehouse, and shed structures. They keep the building dry and stand up to wind and sun without a concrete roof deck.

What thickness of roof sheet do I need for my factory?

Thickness and profile depth depend on your purlin spacing, roof pitch, and local wind load. Send us your roof plan and we'll confirm the right spec on your quote.

How is roof sheet price in Bangladesh calculated?

Roof sheet is priced by weight, coating type, profile depth, and quantity, tracking the current CI sheet and steel coil rate. Send your roof plan for a same-day custom quote.

Can City Steel make custom roof sheet profiles?

Yes. Profile depth, sheet length, and coating are set from your drawing, not sold as a fixed catalogue item.

Is steel roof sheet better than a cast RCC roof?

Steel roof sheet is lighter and goes up faster than a cast RCC roof, which lets your frame carry less dead weight. For roofs needing heavy foot traffic or rooftop equipment, RCC is still the better fit.

Galvanized vs color-coated roof sheet - which should I choose?

Galvanized resists rust at a lower cost; color-coated adds a reflective top layer that cuts roof surface heat and gives a finished look. Tell us your building type and we'll recommend one on your quote.

Do you offer insulated or PVC-coated roofing sheet?

Yes, insulated sandwich-panel roof sheet is available for heat and noise control, and PVC-coated sheet for added chemical resistance — both made to order.

Do you deliver roofing sheet outside Dhaka?

Yes, we deliver to project sites nationwide, including Gazipur, Narayanganj, Savar, and Chittagong.

How long does fabrication and delivery take?

Lead time depends on order size and profile complexity, confirmed after we review your roof plan.

Is the roof sheet certified, and what warranty do I get?

Sheets are made to the standard specified in your drawing (ASTM / BS EN), and every order carries a fabrication/workmanship warranty.
