304 Stainless Steel U-channel

Material and Characteristics
Common Stainless Steel Models:

1.304 Stainless Steel: general purpose, corrosion resistant, high temperature resistant, suitable for most environments.

2.316 stainless steel: containing molybdenum, stronger resistance to chloride corrosion, suitable for marine, chemical and other harsh environments.

3.201 stainless steel: economic, slightly weaker corrosion resistance, suitable for dry or mildly corrosive environments.

Core Features

1.Corrosion Resistance: Resistant to corrosion from acids, alkalis, salt spray, humidity, etc. for long life.

2.High strength: U-shaped cross-section provides good bending and torsion resistance.

3.Aesthetics: the surface can be polished and brushed to maintain a metallic lustre, suitable for decorative purposes.

4.Hygiene and environmental protection: non-polluting, easy to clean, in line with food, medical and other industry standards.

Common specifications and parameters
Size range:

1.Height (leg length): 20mm~300mm

2.Width (bottom): 10mm~150mm

3.Thickness: 1mm~20mm

4.Length: usually 6 metres fixed, can be customized.

5.Standard: in accordance with GB/T 706-2016 (China), ASTM A554 (USA), etc.

production process
1.Cold bending forming: stainless steel coil is bent and formed by cold rolling, with high dimensional accuracy and smooth surface.

2.Hot roll forming: suitable for large-size, thick-walled U-beam, but the surface needs subsequent treatment.

3.Surface treatment: sandblasting, mirror polishing, titanium plating, etc., to enhance the aesthetics or functionality.

Application fields
1.Building decoration: curtain wall keel, ceiling, door and window frames.

2.Industrial equipment: conveyor rails, mechanical supports, storage racks.

3.Transportation vehicles: underground, ship's interior support structure.

4.Food and medical treatment: workbench skeleton, aseptic equipment support.

5.Municipal engineering: bridge guardrail, drainage channel support.

Advantages and Disadvantages
Advantages:

1.Rust-resistant and durable, reducing maintenance costs.

2.Lighter in weight than carbon steel, easy to install.

3.Environmentally friendly and recyclable, in line with sustainable development.

Disadvantages:

1.Cost is higher than ordinary carbon steel U-beam.

2.Processing requires specialised tools (e.g. stainless steel cutter).

Suggestions for selection
1.Environment matching: 316 stainless steel is preferred for humid or chemical environments.

2.Load-bearing requirements: thick-walled or raised leg length can enhance the load-bearing capacity.

3.Budget balance: non-demanding environment can choose 304 or 201 to reduce costs.
