Steel Structure Dairy Shed in Pakistan – Double Slope PEB Dairy Farm Buildings

A steel structure dairy shed is a dairy farm building whose frame is made of structural steel (columns, rafters, purlins and girts) instead of brick and RCC, covered with roof and wall sheeting or insulated sandwich panels. In Pakistan most commercial farms now choose PEB (pre-engineered building) steel dairy sheds because they are fast, column-free, strong and easy to expand.

A double slope (gable) steel dairy shed has a roof that slopes down on both sides of a central ridge. The ridge allows a continuous opening for hot air and ammonia to escape, which is why double slope PEB sheds are the most popular design for dairy farms in Pakistan.

A PEB dairy farm shed is a pre-engineered steel building. The frames are designed by software and fabricated in the factory to exact size, then bolted together on site. It gives wide column-free spans, quick erection and consistent quality compared with conventional construction.

PU sandwich panels give the highest insulation per thickness, EPS panels are the most economical insulated roof, and glass wool is a non-combustible blanket placed under a metal roof sheet. For hot regions and high-yielding Friesian herds, PU or EPS panels, or a roof sheet with glass wool and an internal liner, reduce indoor heat the most.

Yes. A UPVC roof sheet does not rust, so it resists ammonia, urine vapour, humidity and chemicals better than plain metal sheets. It is light, quiet in rain and easy to fix. For hot areas it should be combined with ventilation or an insulated layer because UPVC alone does not insulate heat like a PU or EPS panel.

The external sheet is the outer weather skin, normally a colour-coated or galvanized steel sheet. The internal sheet (liner sheet) is the inside skin that holds the insulation, usually glass wool, and gives a clean, washable ceiling. Together with insulation they form a three-layer roof for a cooler dairy shed.

Plan roughly 80 to 120 sq ft of covered space per adult cow in a covered shed. An open loose housing shed needs about 50 to 75 sq ft of shaded area plus 90 to 120 sq ft of open paddock. Buffaloes and cows with calves need the upper end of the range.

Yes. Sahiwal cows tolerate heat well, so an open-sided double slope steel shed with a ridge opening, shade and good drainage suits Sahiwal and other heat-tolerant breeds. We build sheds in Sahiwal, Okara, Kasur and the whole dairy belt of Punjab.

Yes. Buffalo steel sheds need more shade, a taller roof and stronger drainage for cooling water. We design buffalo sheds with wide bays, cooling-friendly floors and fan or sprinkler supports for Nili-Ravi and Kundi buffaloes.

Because the steel frame is fabricated in the factory while foundations are prepared on site, most steel dairy sheds are erected in a few weeks after the drawings are approved. The exact time depends on the size of the shed and site readiness.

A properly designed and coated steel structure dairy shed lasts for decades. Protective coating, galvanised or colour-coated sheeting and routine checking of bolts and sheets keep the shed in good condition even in humid dairy environments.

For most dairy farms, yes. A steel structure dairy shed is lighter, quicker to erect, gives wider column-free spans, needs smaller foundations and is easy to extend. Brick and RCC are slower and harder to modify, so they are used only where site conditions require them.

Yes. A PEB steel structure dairy shed is modular, so extra bays can be added along the length when your herd grows. Tell us your expansion plan and we design the end frames and services for it.

Yes. We provide ridge ventilators, turbo ventilators, side curtains and supports for fans and misters, and we place translucent roof sheets for natural light where needed.
