A steel godown that keeps stock dry and safe
A godown has one job: keep the stock dry, safe and easy to move in and out. Bongshai Steel builds each godown as a pre-engineered steel building (PEB): built-up columns and rafters cut from MS steel plate form the main frames, and cold-formed purlins, girts and bracing carry the roof and walls. Columns sit on RCC footings through anchor bolts, and every frame connection is bolted with high-strength bolts.
In Bangladesh the floor matters as much as the frame. Water from the yard, damp rising through the floor and a leaking roof spoil more stock than anything else, so a godown is planned from the ground up: a raised plinth, a damp-proof course, a strong floor, closed walls and a roof that sheds the monsoon rain.
Godown sizes and dimensions
These are the ranges for a standard godown frame. The span is set for your stacking plan and truck access; wider and multi-span godowns are engineered per project.
| Parameter | Range | Notes |
|---|---|---|
| Clear span (width) | 10 - 40 m (about 33 - 131 ft) | No inside columns, so stacks and forklifts move freely |
| Length | 30 - 300 m (about 98 - 984 ft) | Grows in bays; can be extended later |
| Bay spacing | 7.5, 9 or 10 m | Chosen for shutter doors and stacking lanes |
| Height | 6 - 10 m (about 20 - 33 ft) | Set by stack height and loading equipment |
| Floor | Raised plinth with an RCC floor | Plinth height set above the local flood level |
What our godowns store
- Rice, wheat, pulses and other food grain
- Fertilizer, seed and other farm inputs
- Cement, rod and building materials
- Finished goods and raw materials for factories
- Stock for wholesalers, distributors and retail chains
- Cold-sensitive goods, with an insulated roof and walls
A dry floor from the ground up
Most godown damage starts below the stock. Our godown civil works follow the same order on every site:
- Earth excavation and RCC column footings for the steel frame
- Sand filling of the plinth in layers, compacted to 95% dry density
- Brick flat soling and a polythene damp-proof sheet under the floor
- A damp-proof course in the walls, about 75 mm thick with a bitumen coat
- An RCC floor slab, typically 150 mm thick, sized for the stack and truck loads
- Brick or concrete lower walls where stock leans on the wall
- A surface drain around the building to carry rain water away
What a godown package includes
Every quotation lists the items one by one, so you can compare offers on the same scope. A typical godown covers:
- Structural design, 2D drawings and shop drawings
- Built-up steel columns, rafters and end-wall posts
- Cold-formed purlins and girts, rod bracing and sag rods
- Anchor bolts, high-strength bolts and connection clips
- Colour-coated roof and wall sheets, ridge caps, flashing and trims
- Roof insulation where the goods or the staff need a cooler building
- Gutters and downspouts sized for monsoon rain
- Roller shutter and personnel door openings framed into the walls
- Primer and finish paint on the steel
- Fabrication in our workshop, transport and erection on site
- Civil works when required: plinth, RCC floor, lower walls and drain
Loads and building codes
A godown is designed for its own site: a basic wind speed of 180 to 210 km/h depending on location, the BNBC seismic zone, and the real floor load of the stock. Grain, fertilizer and cement stacks are heavy, so the floor slab and its sub-base are designed for the stack height you plan, not for a light shed.
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 grade, so your own engineer can check the design basis before you sign.
Options that shape the godown
- Roof ventilators and wall louvres to let out heat and moisture
- Insulated roof and walls for heat-sensitive goods
- Loading canopy over the truck bay and shutter doors
- Raised loading dock at truck-bed height
- Daylight roof sheets to cut lighting cost
- Office or store-keeper room inside the godown
- Boundary wall and gate for a secure yard
A lower-cost godown option
If the budget is tight, the same godown can be built in a simpler form. The saving comes from the size and the finishes, not from a weaker frame. Ways to bring the cost down:
- Keep the span and height to what your stacks really need
- Use a regular bay spacing so the same frame repeats along the length
- Leave out roof insulation where the goods do not mind heat
- Build the first bays now and extend the godown later, with the end frames designed for it
- Add the canopy, dock and office room in a later phase
What we never cut: the wind and seismic design for your site, the frame connections, the plinth and the foundation.
From enquiry to handover
Send us the size, the site location and what will be stored. We study the site, design the frame and send drawings for your approval. Fabrication starts in our workshop while the plinth and foundation are built on site, then the frames are erected and the roof and walls are closed.
A small steel godown can be ready in about 30 days. Most single-storey godowns of warehouse size take about 60 to 120 days with civil works. The clock starts once the contract is signed, the down payment is made, the working drawings are approved and the site is ready.
Storage and industrial projects by the Bongshai Group
Bongshai Steel and its sister company Bongshai Engineering & Construction have built steel buildings in Bangladesh since 2008. Projects of this kind include:
- Logistics Warehouse & Laydown Yards, Dhaka Division (2019): civil works, PEB steel structure, architecture, MEP and water supply
- Heavy Industrial PEB Complex for Kazi Farms (2016): PEB factory buildings, grain handling structures and mezzanine decking
What a steel godown costs
The price of a godown depends mostly on span, height, the floor load, insulation and how much civil work is included. A low price per square foot can hide a thin frame, a weak floor or a missing plinth, so compare quotations on the same scope.
Godown questions
What is the difference between a godown and a warehouse?
Both use the same steel frame. A godown is usually built for bulk storage such as grain, fertilizer or cement, so the raised plinth, the floor slab and keeping the stock dry matter most. A warehouse is more often planned around racking, loading docks and fast movement of goods.
How do you keep the godown floor dry?
The plinth is raised above the local flood level with compacted sand filling, then brick soling, a polythene damp-proof sheet and an RCC floor slab go on top. A damp-proof course in the walls and a surface drain around the building keep water out.
How long does it take to build a steel godown?
A small steel godown can be ready in about 30 days. Most single-storey godowns of warehouse size take about 60 to 120 days with civil works. Time is counted from contract signing, down payment, drawing approval and site handover.
Can the godown carry heavy stacks of grain or cement?
Yes. The floor slab and its sub-base are designed for the stack height and truck loads you plan, and the walls are given brick or concrete lower parts where stock leans against them.
Which building codes do you follow?
We follow BNBC 2020 for loads, AISC 360 for steel design and AWS D1.1 for welding. The design loads and steel grade are written in every quotation.
Can the godown be extended later?
Yes. A steel godown grows by adding bays at the end walls. Tell us early if you plan to extend, so the end frames and foundations are designed for it.
Do you build godowns outside Dhaka?
Yes. We quote and build for sites anywhere in Bangladesh. Send the location and size and the engineering team will reply with a site-visit plan or a quotation.
