RUNYING Steel Group is a premier Tangshan-based manufacturer and exporter of heavy-duty Hot-Rolled & Cold-Formed Structural C Channels (U Channels / UPN / UPE profiles). Engineered to deliver exceptional bending resistance and structural stability, our C channels are widely utilized in heavy building frameworks, vehicle chassis, bridge support girders, and industrial equipment platforms worldwide.

Technical Specifications & Dimension Standards

Our structural C channels are manufactured from high-grade structural steel billets under strict chemical and mechanical quality controls:

Primary Structural Differences: C Channel vs. C Purlin

To assist structural engineers and procurement teams in material selection:

Structural C Channel (This Product Page): Produced via hot-rolling or heavy cold-forming with thick webs (4.5mm–14.5mm). Used as primary load-bearing columns, bridge girders, heavy machinery bases, and truck bed chassis.

C Purlin (Roofing Profile): Cold-formed from thin galvanized steel coils (1.5mm–3.0mm). Used primarily as secondary roof cladding framing, wall girts, and lightweight floor joists.

Key Performance Advantages

High Moment of Inertia & Bending Resistance:

Tapered or parallel flange engineering provides maximum load distribution across wide horizontal spans.

Superior Weldability & Machinability:

Low carbon equivalent ensures effortless on-site welding, flame cutting, and flange drilling without preheating.

Extreme Atmospheric Durability:

Optional heavy hot-dip galvanizing protects channel steel from coastal salt spray, industrial chemical exposure, and humidity.

Primary Engineering Applications

Building Construction: Structural framing for industrial workshops, warehouse mezzanine floors, and stair stringers.

Heavy Equipment & Transportation: Truck chassis frames, trailer side rails, agricultural machinery beds, and crane gantry supports.

Infrastructure & Utilities: Solar panel racking systems, transmission line towers, highway guardrail posts, and bridge abutments.

Seaworthy Packaging & Tianjin Port Shipping

Export Bundling: Supplied in 1.5 MT – 3.0 MT heavy-duty steel bundles bound with dual high-tensile steel strappings and protective end lifting slings.

Logistics Advantage: Direct container stuffing and breakbulk vessel dispatch from our staging yards near Tianjin Port, China.
