Strut channel Unistrut Bracket Bracing System
Strut channels are manufactured by a series of forming dies, or rolls, which progressively cold work the strip steel into the desired channel configuration. This method produces a cross-section of uniform dimensions within a tolerance of ±0.015″
Tolerance:
Length tolerance: +/-1/8″ (3.175mm)
External dimension (width/height) tolerance: 0.015″ (0.381mm)
Material and wall thickness:
- 12Gage (Normal 0.1084″ (2.75mm), minimum 0.0994″ (2.52mm), maximum 0.1174″ (2.98mm))
- 14Gage (Normal 0.0785″ (2mm), minimum 0.0705″ (1.8mm), maximum 0.0865″ (2.2mm))
- Material: Q235B galvanized sheet
