C Channel
- Hot rolled U-type carbon channel steel covers full specifications from Size 5# to 40#, offered in grades A36, S235JR, SS400 and Q355B to meet diverse regional engineering standards. Boasting high section modulus and outstanding bending resistance, it maintains stable mechanical performance under static and moderate dynamic loads. Standard sizes are sufficiently stocked, and custom cutting is available to minimize on-site processing. Widely used for workshop beams, warehouse uprights, vehicle chassis, equipment supports and pipeline brackets. Strict factory inspections ensure reliable dimensional precision and surface quality, serving as an ideal structural material for construction, machinery manufacturing and transportation sectors.
Certified
Each shipment provides EN 10204 3.1 mill test reports including chemical, tensile, bending and hardness test. Conform to ASTM, EN, JIS, GB standards. Support SGS/BV third-party inspection, full heat number traceability for metal traders.
Application
Channel steel is classic U-shaped load-bearing profile for construction, machinery and logistics sectors. In building engineering, it is used as secondary floor beams, wall purlins and overhead crane track bases. Low carbon grades fit multi-story industrial buildings, while Q355B channel suits large-span heavy load steel structures. Mechanical factories use channel steel for machine tool bases and mining equipment supports, its U groove reserves space for pipelines and cables. Transportation industry applies galvanized channel for truck cross beams and container bottom supports, with stable anti-rust performance in coastal humid environments. It is the core raw material for warehouse rack uprights and cable trench supports, with punching and galvanizing services available.
