Product Description

Back-to-Back Strut Channel conforming to GB specifications are manufactured from cold-formed carbon steel strip for structural support applications. Available in profiles including 41x41, 41x21, 41x62, and 41x82mm with thickness options of 1.6mm, 2.0mm, and 2.5mm. Standard lengths are 3m and 6m. Standard materials include carbon steel Grades 4.8, 8.8, and 10.9, with stainless steel A2 (304) and A4 (316) available for corrosive environments. Brass and special alloys are available for specific applications. Surface treatments include H.D.G.. Zinc plating (Z.P.L) provides 48-96 hours salt spray protection for general indoor use. Black zinc phosphate (B.Z.P) offers matte appearance with mild corrosion resistance. Nickel plating (Ni.P) provides superior wear and chemical resistance. Decromet coating delivers automotive-grade protection exceeding 500 hours per ASTM B117. Ruspert ceramic coating provides extended outdoor and marine exposure protection up to 1000 hours. Hot-dip galvanizing provides heavy-duty atmospheric protection for outdoor structural applications.

Typical applications span electrical conduit support, HVAC duct mounting, pipe hanging, cable tray installation, lighting fixture support, and general mechanical support in commercial and industrial construction. These fasteners are designed to meet or exceed applicable international standards for dimensional accuracy and mechanical performance. Aufaster supplies these products in bulk packaging with full material traceability per EN 10204 Type 3.1, dimensional inspection reports, and mill test certificates available on request. Custom sizes, special materials, and non-standard finishes are available for OEM customers with volume requirements.
