Engineering Breakdown

What are the engineering specifications of BongshaiSteel-101?

Structural Design and Load Capacity

The Affordable Heavy-Duty Steel Structure Factory Building (BongshaiSteel-101) is engineered by Bongshai Steel's in-house structural engineers to withstand high wind velocity, seismic forces, and heavy dead/live loads. All primary framing members are fabricated from certified structural grade steel, pre-drilled, pre-punched, and precision-cut for rapid on-site bolted assembly.

Surface Treatment and Corrosion Protection

Steel components are sandblasted and finished with an epoxy anti-corrosion coating in the Bongshai Steel factory before dispatch, for service in coastal and demanding industrial environments.
