About Bongshai Steel
Bongshai Steel is a steel building manufacturer and exporter based in Bangladesh. It designs and builds pre-engineered steel buildings: PEB steel buildings, commercial steel buildings, residential steel buildings and structural steel. Every building is engineered to the buyer's size and use.
- PEB steel buildings: factory buildings, warehouses, godowns, farm houses, indoor stadiums, auditoriums and aircraft hangars.
- Commercial steel buildings: supermarkets, schools and colleges, offices, banks, universities, hospitals and community centers.

Design follows the Bangladesh National Building Code (BNBC) and American codes: IBC, ASCE 7, AISC 360, AWS D1.1 and MBMA. The published models use the AISC, AISI and BSI design standards, with load combinations to MBMA and IBC.
The head office is in Uttara, Dhaka. Bongshai Steel has started exporting, and its quotes include sea freight. Some models show a starting price on their page; the final price depends on the size, site and finish of the building and is given in a written quotation.
A project starts with a quote request. Browse the model catalogue, read the PEB price guide, or design a frame in the free 3D steel building configurator: set the framing system, width, length, eave height, bay spacing, roof and walls, doors, lean-to, crane and mezzanine, and send the building to Bongshai Steel for a quotation by form or WhatsApp. The configurator is a planning preview; the final design is done for the site and its loads to BNBC or American codes, and the price comes in a written quotation.
