Sigma shape

The beam profiles are cold-formed and used as structural members for modular steel framed buildings.

The beams are used for constructing curtain and partition walls, as well as for ceiling joists, eaves beams, frame beams and roof purlins. 

Balex Metal manufactures three types of beam profile: Sigma, C and Z-bar. Each beam type can be delivered with a custom, pre-drilled hole arrangement.
