Manufacturer Stock Galvanized and Stainless Steel Triangle Iron Angle Steel

The specifications and models of angle steel (triangle iron) are identified by "edge width x edge width x edge thickness" as the core (unit: mm), combined with parameters such as material, length, and surface treatment to form a complete model, such as "Q235B 50 × 50 × 56m". Among them, edge width is the core of specification division, commonly ranging from 25mm to 200mm, such as 25 × 25, 50 × 50, etc; The edge thickness determines the bearing capacity and is matched with the edge width, usually between 1.6mm and 20mm, such as 50 × 50 × 3 and 50 × 50 × 5. In terms of material, Q235 plain carbon steel has a tensile strength of 375-500MPa, which is cost-effective and suitable for room temperature, medium and low load scenarios; Q355 low-alloy steel has a tensile strength of 510-660MPa, suitable for low temperature, heavy load, and impact resistance scenarios. The standard length is 6m, 9m, 12m, and can also be customized to any length of 1-12m as needed. In terms of surface treatment, black skin does not have rust prevention treatment and is only used for indoor dry and non exposed scenes; Hot dip galvanized zinc layer with a thickness of 85 μ m or more, resistant to salt spray and moisture, suitable for outdoor, outdoor, and coastal scenes; Spray painted/passivated paint film thickness of 30-50 μ m, suitable for indoor mild corrosive environments.
