Angle Brackets

Angle Brackets — also called angle brackets or L-brackets — provide structural reinforcement at 90° connections in curtain wall systems and steel frameworks.

At Fabao Machinery, we supply corner braces in carbon steel (Q235B), stainless steel (304/316), and aluminum alloy, with custom dimensions, hole patterns, and surface treatments available. Hot-dip galvanizing, electro-galvanizing, and powder coating options come standard. Custom orders based on your drawings are welcome.
