Overview
Rep Materials’ Pre-Galvanized Deep Strut Channel metal framing is used to support conduit, panel boxes, raceway systems and other electrical components. Strut Channel raceways are exceptionally versatile in that the support systems can be attached to ceilings, wood or steel beams, inside columns or imbedded in concrete.
Strength and Durability
Steel strut combines strength, durability, and corrosion resistance, making it a reliable choice for various construction and engineering projects where stability and longevity are essential. Back-to-back configuration provides enhanced structural capacity.
Manufacturing Process
Material (steel strip) is immersed in a galvanized bath prior to roll-forming or press operations that cold works the strip steel into the desired channel profile. This method produces a cross section of uniform dimensions within a tolerance of +/- .015″.
Coating Quality
Rep Material’s Pre-Galvanized Strut coating conforms to ASTM A653, Grade 90 General Requirement for Steel Sheet, Zinc–Coated (Galvanized) by Hot Dip Process. Provides superior corrosion protection for long-term reliability.
Design Features
Elongated holes provide flexibility for installation and adjustment. Back-to-back configuration (3-1/4″ X 1-5/8″ 12 gauge) offers increased load capacity and structural performance for demanding applications.

Important Load Notes
*Load limited by spot weld shear
This load table is based on a solid channel section STR-12G-158-158-SLD
For elongated hole channels STR-12G-158-158-EHO reduce beam load values by 15%
For concentrated load at center of span, divide uniform load by 2 and multiply corresponding deflection by .80
Loads include weight of channel, which must be deducted
Loads must be multiplied by the applicable unbraced factor from the “Lateral Bracing Load Reduction Chart”
