BridgeBar® Bridging Channel


Product Application

BridgeBar® replaces cold-rolled channel (CRC) for wall bridging. Unique grooves every 4” trap stud web to allow installers to space any type of wall layout. The grooves adjust to various stud thickness to trap the stud web for maximum strength. BridgeBar incorporates stiffeners to resist compressive loads through the plane of the wall. BridgeBar’s standard U-channel shape ensures use through ¾” and 1½” stud punchouts.

Material Composition

BridgeBar® 150: ASTM A653/A653M, Grade 50 (340), 50ksi (340MPa) minimum yield strength, 65ksi (450MPa) minimum tensile strength, G90 (Z275) hot-dipped galvanized coating.

BridgeBar® 75: ASTM A653/A653M, Grade 33 (230), 33ksi (230MPa) minimum yield strength, 45ksi (310MPa) minimum tensile strength, G60 (Z275) hot-dipped galvanized coating.

Material thickness = 33mil (20ga, 0.0346” design thickness- BB150); = 28mil (22ga, 0.0295” design thickness-BB75).
