Steel farm buildings

Steel farm sheds built for animals and the weather

A farm building has to keep animals cool, dry and healthy, and stand up to the wind and the monsoon for many years. Bongshai Steel builds cattle sheds, poultry sheds and farm stores with a steel frame: steel columns and rafters form the main frames, and purlins, girts and bracing carry the roof and the side walls. Columns sit on RCC footings through anchor bolts, and the frame connections are bolted.

A steel frame needs no bamboo or timber posts that rot at the base, gives a clear floor that is easy to clean, and can be lengthened when the herd or the flock grows. One team does the design, fabrication and erection, and the floor and civil works when you want them.

Sizes

Farm shed sizes and dimensions

These are the ranges for a standard farm shed frame. Poultry sheds are usually long and narrow, for example 100 ft x 35 ft, and some run up to 300 ft long; cattle sheds are set by the number of animals and the feeding lanes.

Uses

Farm buildings we design and build

  • Dairy and beef cattle sheds with feeding and milking lanes
  • Broiler and layer poultry sheds, including broiler-to-layer conversion
  • Feed, fodder and grain stores
  • Farm machinery and equipment sheds
  • Agro processing and packing sheds
Scope

What a farm shed package includes

Every quotation lists the items one by one, so you can compare offers on the same scope. A typical cattle or poultry shed covers:

  • Design and drawings for the shed and its foundation
  • Steel columns, rafters and purlins
  • Colour-coated roof sheet with bubble insulation under it
  • Side nets or wire mesh for air and protection from birds and animals
  • Side curtains for poultry sheds, to close against rain and cold
  • Brick lower walls where animals lean or the floor is washed
  • RCC footings and tie beams
  • Sand-filled raised plinth with a plastered hard floor
  • Drains along the shed for washing and rain water
  • Doors, flashing, gutters and accessories
  • Primer and paint on the steel
  • Electrical wiring for lights and fans
  • Fabrication, transport and erection on site
Climate

Cool, dry and easy to clean

Heat is the biggest problem for cattle and poultry in Bangladesh. An insulated roof cuts the heat that comes down from the sheet, the open or netted sides let air move through, and the height above the animals lets warm air rise and escape. In poultry sheds, side curtains close the shed against driving rain and cold nights.

The floor is raised above the yard on a compacted sand plinth, so rain water does not run in, and it is finished hard and sloped to drains so it can be washed every day. Steel parts are cleaned and painted with primer and finish paint against the damp of a farm.

Design basis

Loads and building codes

A farm shed is light, but its wide roof catches the wind. Each shed is designed for its own site: a basic wind speed of 180 to 210 km/h depending on location and the BNBC seismic zone, plus fans, lights and any equipment hung from the frame.

We follow BNBC 2020 for loads, AISC 360 for steel design and AWS D1.1 for welding. Every quotation states the design loads and the steel sizes, so your own engineer can check them before you sign.

Budget option

A lower-cost farm shed option

Many farms start small. The same shed can be built in a simpler form and grow later. The saving comes from the size and the finishes, not from a weaker frame. Ways to bring the cost down:

  • Start with the bays you need now and add more as the herd or flock grows
  • Use nets or curtains on the sides instead of full walls
  • Keep brick walls low, only where animals lean or the floor is washed
  • Use a regular bay spacing so the same frame repeats along the length

What we never cut: the wind design for your site, the frame connections, the foundation and the raised floor.

Timeline

From enquiry to the first animals

Send us the number of animals or birds, the site location and a rough size. We plan the shed, send drawings for your approval, and fabricate the steel in our workshop while the plinth and footings are built on site. Then the frames are erected, the roof is closed and the sides, floor and drains are finished.

A small farm shed can be ready in about 30 days, and a larger shed with full civil works in about 60 days. The clock starts once the contract is signed, the down payment is made, the drawings are approved and the site is ready.

Track record

Agro projects by the Bongshai Group

Bongshai Steel and its sister company Bongshai Engineering & Construction have built steel buildings in Bangladesh since 2008, including agro-industry work:

  • Heavy Industrial PEB Complex for Kazi Farms (2016): PEB factory buildings, grain handling structures and mezzanine decking

Price

What a steel farm shed costs

The price of a farm shed depends mostly on its size, the roof insulation, the side walls and how much floor and civil work is included. A low price can hide thin steel or a floor that is not raised, so compare quotations on the same scope.

FAQ

Farm House questions

Which is better for a cattle shed, steel or bamboo and timber?

A steel frame lasts much longer, does not rot at the base, needs fewer posts inside the shed and can be extended later. Bamboo and timber cost less at the start but need repair and replacement much sooner.

How do you keep a steel farm shed cool?

The roof sheet has bubble insulation under it, the sides are open with nets or curtains so air moves through, and the shed is tall enough for warm air to rise above the animals. Fans can be added on the frame.

What size should a poultry shed be?

Poultry sheds are usually long and narrow, for example 100 ft x 35 ft, and some run up to 300 ft long. We set the width and length from the number of birds, broiler or layer, and your site.

Can you convert a broiler shed to a layer shed?

Yes. We repair, convert and extend existing poultry sheds: new roof sheet and insulation, nets and curtains, painting of the old steel, and new floor and drains where needed.

How long does it take to build a farm shed?

A small farm shed can be ready in about 30 days, and a larger shed with full civil works in about 60 days, counted from contract signing, down payment, drawing approval and site handover.

Do you build the floor and drains too?

Yes. We can quote the steel shed alone, or include the raised plinth, the hard floor, the brick lower walls and the drains so one team is responsible for the whole shed.

Do you build farm sheds outside Dhaka?

Yes. Most farms are outside the city, and we quote and build anywhere in Bangladesh. Send the location and the number of animals or birds and we will reply with a plan or a quotation.
