ASTM A276 316L Stainless Steel U-Channels

GNEE has become a trusted supplier of ASTM A276 316L stainless steel U channels, with products exported to over 160 countries and regions worldwide. Our products are widely used across industries such as marine, offshore engineering, construction, chemical processing, food, and pharmaceuticals.

 

GNEE supplies 316L stainless steel U channels in compliance with ASTM A276 standards, manufactured באמצעות precision cold forming and bending processes to ensure stable cross-sectional geometry and excellent structural consistency.

SS 316L U channels are supplied with a standard mill finish, with optional surface treatments including pickling and passivation, brushed finish (No.4), and bright annealing to meet different application requirements. All profiles are deburred to ensure safer handling, easier installation, and improved assembly accuracy.

We offer both standard and customized U channel specifications, with flange height (leg length) ranging from 15 mm to 150 mm and wall thickness from 2.0 mm to 12 mm. The maximum length per piece can reach up to 6 meters, with dimensional tolerances strictly controlled within ±0.1 mm. All U channels undergo heat treatment or pickling processes, straightening, and comprehensive inspections for straightness, density, and surface quality.

Why Choose GNEE?

GNEE operates a large, modern warehousing facility and maintains a ready stock of commonly used standard 316L channel steels (such as UPN and UPE specifications). We support small-batch orders, catering to the specific requirements of pilot projects or small-scale engineering works. We also offer laser-welded channel steels-a solution that enables the production of ultra-large dimensions or unique shapes that are unachievable through traditional hot-rolling methods-with weld strength equivalent to that of the base material.

 

Material Traceability: Every channel steel beam is accompanied by an original manufacturer's material certificate (MTC 3.1).
Third-Party Inspection: Upon customer request, we can arrange for SGS, TUV, or BV to conduct chemical composition analysis, tensile testing, and ultrasonic testing.

Global Export Expertise:
Proficient in international standards for maritime packaging (including wooden crates, steel strapping, and waterproof sheeting).
Extensive experience in customs clearance and export documentation processing, ensuring efficient delivery to destinations worldwide.
