Zero Accident Commitment

Health And Safety Policy (EHS)

Safety comes first on every Bongshai Steel job, in the workshop and on site. These are the rules our teams work to.

  • Personal protective equipment on every site: hard hat, safety shoes, gloves, and a harness for work at height.
  • A safety briefing before work starts on site, and a lifting plan before every crane lift.
  • Fabrication and erection follow the approved engineering drawings and erection sequence.
  • Lifting gear and slings are checked before use; damaged equipment is taken out of service.
  • The work area is closed off during lifting and work at height, keeping the public and other trades clear.
  • Every design is checked to its code: BNBC, or American codes (IBC, ASCE 7, AISC 360, AWS D1.1, MBMA) where the project needs them.

Frequently Asked Questions

Answers to the questions clients ask us most often.

Reviewed by Bongshai Steel Engineering Team • Last updated:

What is a pre-engineered steel building?

A pre-engineered steel building (PEB) is a steel structure whose members are designed and fabricated in the workshop, then bolted together on site. It suits buildings that need wide open floor space, such as factories and warehouses.

What types of buildings do you make?

Factories, warehouses, godowns, farm houses, indoor stadiums, auditoriums, aircraft hangars, supermarkets, schools, offices, banks, hospitals, community centres, duplex and cottage houses, container houses, hotels and resorts, accommodation units, and structural steel such as pipe racks, equipment supports, girders and columns.

How do I get a price for my project?

Send us your building size, its use, the site location and the finish you want, through the website form, WhatsApp or phone. We reply with a written quotation.

What information should I send with a quote request?

The length, width and height you need, what the building will be used for, where the site is, and any finish or cladding preferences. Drawings or photos of the site help if you have them.

Can the design be changed to suit my needs?

Yes. Every project is designed for the client. You can try clear span, multi-span, multi-gable and single slope frames in our online 3D configurator, and we refine the design with you.

What sizes can you build?

Each building is designed to the size the client needs. Tell us the floor area and heights you require, and we will recommend a suitable framing system.

Does the 3D configurator give me the final design?

No. The configurator is for exploring sizes and framing options. The final design is prepared by our engineers after we know your site conditions and loads.

Which building code do you follow?

We design to the Bangladesh National Building Code (BNBC) and to American codes: IBC, ASCE 7 for loads, AISC 360 for steel, AWS D1.1 for welding and the MBMA manual for metal buildings, as the project requires.

Do you export steel buildings?

Yes, we have started exporting. Tell us your country and site, and we will quote with sea freight and the design code your project needs: BNBC or American codes.
