Factory and Warehouse Steel Buildings for EPZ and Economic Zone Investors
You have a plot in an export processing zone or an economic zone. The next step is the building. Bongshai Steel designs, fabricates and erects steel factory and warehouse buildings from its own factory in Bangladesh, with one team from the first drawing to handover and every document in English.
Why zone investors build in steel
A lease starts costing money the day it is signed, so the building that goes up fastest earns first. A steel building is fabricated in the factory while the foundation is cast on site, and the frame is bolted together when it arrives. For a single-storey factory or warehouse that takes months off the programme of a concrete building.
Steel also gives the wide column-free floor that production lines, racking and forklifts need, and the building can be extended later by adding bays to the end wall when the business grows.
One contract if you want it
Foundations, floor slab and building services can be included through Bongshai Engineering, so you deal with one party for the whole building.
From plot to handover
The same six steps for a factory, a warehouse or a utility building.
Your requirements
Plot size, building length, width and eave height, crane loads, floor loads, and the zone your plot is in.
Concept and itemized quotation
A layout and a quotation that lists the design basis, the specification, and what is and is not included.
Structural design
Design to AISC 360 and BNBC 2020 for the wind and earthquake zone of your site, with drawings and calculations for the zone authority's approval.
Fabrication
Frames, purlins and connections are cut, welded to AWS D1.1 and painted in our own factory.
Erection
Our crews bolt the frame together on your foundations and fix the roof and wall sheet.
Handover
As-built drawings and the building, ready for your machinery and fit-out.
What to send for a quotation
The more of this we have, the closer the first quotation is to the final price.
Plot and zone
The zone name and plot size, and the plot plan if you have it.
Building size
Length, width and clear eave height, and the number of floors or mezzanines.
Cranes and heavy loads
Overhead crane capacity and span, and any heavy machine or storage load on the floor.
Use of the building
Production, warehouse, cold storage or utilities. It decides insulation, ventilation and fire details.
Scope
Steel building only, steel with erection, or the whole building with foundation and floor.
Programme
When the plot is handed over to you and when production has to start.
Built in Bangladesh, to international codes
Bongshai Steel designs, fabricates and erects pre-engineered steel buildings and structural steel from its own factory, following AISC 360, BNBC 2020 and AWS D1.1. Completed work on our projects page includes buildings at the Saidpur, Ghatail and Rangpur cantonments and the IGS building at Dhaka Cantonment. Our office is in Uttara, Dhaka, and we build on sites across Bangladesh.
Frequently asked questions
Do you build inside EPZs and economic zones?
Yes. We quote for sites across Bangladesh, including the export processing zones, economic zones and industrial parks. Distance from Dhaka changes only the transport and site-crew cost.
Which design codes do you follow?
AISC 360 for steel design, BNBC 2020 for loads including wind and earthquake for your site, and AWS D1.1 for welding. If your company or your buyer needs another standard, tell us with the enquiry.
Are drawings and documents in English?
Yes. Drawings, design calculations, the itemized quotation and the contract are in English.
Can you do the foundation and floor as well?
Yes. Civil works and building services are done through Bongshai Engineering, so the whole building can be under one contract. You can also order the steel building alone and use your own civil contractor.
How long does a steel factory building take?
Design, fabrication and erection for a typical single-storey factory or warehouse take a few months, far less than a concrete building of the same size, because the steel is fabricated while the foundation is cast. The programme for your building is written in the quotation.
How is the price given?
In a written, itemized quotation for your building: design basis, steel grade, sheet specification, and what is and is not included. Steel prices move with the exchange rate, so each quotation carries a validity date.
Can the building be extended later?
Yes, if it is planned. Tell us the future size and we design the end wall and foundations so bays can be added without stopping production.
