Angle steel, with its L-shaped cross-section, is known for its high strength, easy processing, and wide range of applications, making it an ideal choice for industries such as construction, machinery manufacturing, bridges, and power transmission towers. Whether you're a professional engineer or a DIY enthusiast, angle steel offers an economical and high-performance solution for your needs.

1. Angle Steel Specifications, Materials, and Sizes

Angle steel comes in a variety of specifications, with common sizes including:

Leg Length: 20mm to 200mm (e.g., 20×20mm, 50×50mm, 100×100mm).

Thickness: 3mm to 20mm.

Length: Typically 6 meters or 12 meters, but customizable to meet specific requirements.

Materials:

Q235B: Ordinary carbon structural steel, suitable for general construction and machinery manufacturing.

Q345B: High-strength low-alloy steel, ideal for high-strength applications like bridges and heavy equipment.

Stainless Steel: Such as 304 stainless steel, suitable for corrosion-resistant environments like food and medical industries.

Weight Calculation Formula:

Weight of angle steel (kg/m) = 0.00785 × thickness × (leg length 1 + leg length 2 - thickness)

Example: Weight of 50×50×5mm angle steel = 0.00785 × 5 × (50 + 50 - 5) = 3.77 kg/m.

2. Angle Steel Production Process and Workflow

Hot Rolling Process

Steel billets are heated to high temperatures and formed into angle steel through rolling mills.

Hot-rolled angle steel has a slightly rough surface but high strength, making it suitable for general structural purposes.

Cold Drawing Process

Hot-rolled angle steel is further processed at room temperature to improve dimensional accuracy and surface finish.

Cold-drawn angle steel is ideal for precision machinery parts and high-precision installations.

Surface Treatment

Galvanizing: Enhances rust resistance, suitable for outdoor environments.

Painting: Improves aesthetics, ideal for decorative purposes.

Polishing: Increases surface smoothness, suitable for food and medical equipment.
