Our builds

Real structural steel and light gauge steel, on the ground.

3D engineering & BIM

From BIM model to machine-ready steel.

A closer look at the engineering behind our residential work. Each sample project is built as a 3D digital twin in Vertex BD, then converted to the machine language that drives the roll-forming line, one model producing the isometric drawing, the panel layouts, and the studs and tracks themselves. Open any project to step through its 3D model, panels, and on-site framing.

Selected projects

Panelized light gauge steel at scale.

Larger hotels and senior-living communities framed in panelized light gauge steel. These were delivered in collaboration with Advanced Building Systems (ABS), the company through which our team built its multifamily and hospitality LGS capability. We show them to illustrate the scale and capability of the system, not as projects built solely by Cal Steel.
