Certified with RoHS, it ensures compliance with environmental safety standards, offering buyers peace of mind regarding market access.

Product Specifications and Supply

UPN Series Channel Steel: The reference information mentions European standard channel steel specifications such as UPN100, UPN180, and UPN200, with materials including S355J2.

For example, UPN200 channel steel can be used for building supports or lead-lined water tanks.

Cold-Rolled U-Shaped Steel: Some suppliers offer cold-rolled U-shaped steel (C/U Channel), but few are explicitly labeled as cold-rolled in the reference information; most are hot-rolled or thermomechanically rolled products.

Key Features

Material and Standards: A36 steel typically has higher chemical composition and mechanical property requirements than national standards, exhibiting better strength and toughness.

Zinc Plating Process: Surface galvanizing (hot-dip galvanizing) effectively prevents corrosion and is suitable for harsh environments such as strong acids and alkalis.

Specifications and Shapes: Common specifications include the UPN series (such as UPN80-UPN200), with shapes of U-shaped or C-shaped channel steel.

U-shaped steel (channel steel) manufactured using Q235 or Q195 steel.

Choosing Q235: If the U-shaped channel steel is used in projects requiring heavy loads, such as building support beams, bridges, and vehicle manufacturing, Q235 is a more suitable choice.

Choosing Q195: If used in non-load-bearing structures, hardware products, or scenarios with high forming requirements (such as bending and stamping), Q195 has a greater cost advantage.

Chemical Composition of Stainless Steel Channel Steel

304 Stainless Steel: Contains 18% chromium and 8% nickel, molybdenum-free.

316L Stainless Steel: Contains 2-3% molybdenum compared to 304, with a carbon content ≤0.03% (low-carbon version).

Performance Impact: Molybdenum significantly improves the corrosion resistance of 316L in chloride environments (such as marine and chemical environments), but its cost is 20%-50% higher than 304.

Channel steel is primarily made of carbon structural steel or low-alloy structural steel. Common materials include Q235 and Q345. In addition, some channels for special applications may be made of stainless steel, and the specific material can be customized based on your needs.
Common Material Characteristics
Carbon structural steel: Represented by Q235 and Q345, these are ordinary carbon steels with low cost and suitable for general structural needs.
Low-alloy structural steel: These are ordinary carbon steels with alloying elements (such as manganese and silicon) added to enhance their strength and toughness.
Stainless steel: Types such as 201, 304, and 316L offer enhanced corrosion resistance and are suitable for use in humid or corrosive environments.
Applications
Ordinary carbon steel: Common applications include building structures, machinery and equipment, and vehicle manufacturing.
Stainless steel: These are often used in harsh corrosive environments, such as marine engineering and chemical equipment.
