7-ELEVEN

7-ELEVEN: commercial steel building in Thailand, 2020. World Steel – structural steel fabricator in Vietnam – provided design, fabrication and supply (791 t).

7-ELEVEN is a commercial steel building in Thailand. World Steel designed, fabricated and supplied the steel structure – about 791 tonnes of steel, exported in 2020. Design and fabrication follow US structural steel standards – AISC 360, AWS D1.1 and ASTM materials.

World Steel handles each pre-engineered steel building as one package – shop drawings, fabrication and surface protection – from its factory in Tay Ninh, Vietnam. Export orders to Thailand are bundled, labelled and containerised for export supply, with erection drawings for the installer.

Tiêu chuẩn thiết kế & chế tạo

Like World Steel’s other projects in Thailand, the steel structure was designed and fabricated to US standards: loads to ASCE 7, design to AISC 360 and AISI S100 (cold-formed purlins and girts), MBMA practice for the metal building system, materials to ASTM, welding to AWS D1.1, high-strength bolting to the RCSC Specification and surface preparation to SSPC.
