Connection Parts

Connection parts(Connectors) link different structural components in curtain wall and steel frameworks — from U-shaped connectors and angle splices to custom welded brackets. Each piece acts as a critical joint that transfers loads securely between members.

At Fabao Machinery, we supply connection parts in carbon steel (Q235B) and stainless steel (304/316), with hot-dip or electro-galvanizing finishes. Custom configurations based on your drawings are always welcome.
