Stainless U-Beam Channel Steel
Stainless U-beam channel steel (also called stainless steel channel bar) is a U-shaped structural profile with a vertical web and two horizontal flanges, made from corrosion-resistant stainless steel. It offers a balance of strength, lightweight design, and durability, making it ideal for applications where rust resistance and structural integrity are critical.
Product Parameters

Features


Common stainless steel grades used:

304/304L – General-purpose, good corrosion resistance.

316/316L – Superior resistance to chlorides (marine/chemical environments).

Duplex (2205/2207) – High strength & pitting resistance.

430 – Cost-effective but less corrosion-resistant.


2. Types & Dimensions

Standard U-Channel: Symmetrical flanges (e.g., 40×20×3mm).

Custom Profiles: Uneven flanges or reinforced thickness.


Common Sizes:

Depth (Web Height): 20mm – 300mm

Flange Width: 10mm – 100mm

Thickness: 1mm – 20mm


3. Advantages

Corrosion Resistance – No rust, ideal for humid/chemical environments.

High Strength-to-Weight Ratio – Strong yet lighter than carbon steel.

Easy Fabrication – Can be welded (TIG/MIG), cut, and bent.

Aesthetic Appeal – Polished or brushed finishes for architectural use.
