Angle Steel is a long steel strip with an "L"-shaped cross section, consisting of two perpendicular sides. It is widely used in power equipment, building structures, machinery manufacturing, bridge engineering and other fields. As a basic profile, angle steel has become one of the core materials for industrial fastening and structural support due to its excellent mechanical properties and flexible application scenarios. The angle steel produced by Handan Jinmai Fastener Manufacturing Co., Ltd. strictly implements international standards (such as ASTM, EN, JIS, etc.), which can meet the diverse needs of global customers for precision, strength and weather resistance.
1. High strength and durability
Made of high-quality low-carbon steel or alloy steel, it has high tensile strength and bending resistance, suitable for heavy-duty environments.
2. Corrosion-resistant treatment
Optional hot-dip galvanizing, plastic spraying or anti-rust coating process, effectively resisting erosion in humid, acidic and alkaline environments, and extending service life.
3. Accurate size
CNC cutting and automated forming technology ensure that the verticality error of the corners is ≤0.5°, and the length tolerance is controlled within ±1mm.
4. Flexible adaptability
Supports customized specifications (edge width 20-200mm, thickness 3-20mm), can be welded, drilled or bolted, and adapted to complex installation scenarios.
5. Environmentally friendly process
The entire production process complies with the ISO 14001 environmental management system to reduce carbon emissions and resource waste.

1. Raw material screening
Select high-purity steel billets, and use a spectrometer to detect the chemical composition to ensure material uniformity.
2. Hot rolling
After the steel billet is heated to 1200℃, it is rolled multiple times to form an "L"-shaped section, and then the grain structure is refined by a controlled cooling process.
3. Surface treatment
Use a continuous hot-dip galvanizing line (zinc layer thickness ≥ 80μm) or electrostatic spraying to improve corrosion resistance.
4. Finishing and testing
Laser straightening equipment corrects deformation, three-coordinate measuring instrument verifies dimensional accuracy, and 100% passes eddy current flaw detection and hardness testing.
5. Packaging protection
Anti-rust paper + wooden pallet packaging, corners are equipped with sheaths to avoid transportation damage.
Material: Q235B (national standard) / SS400 (Japanese standard) / A36 (American standard), tensile strength ≥370MPa.
Standard specifications: side width 25×25mm to 150×150mm, thickness 3-16mm, length 6m/9m/12m (supports fixed-length cutting).
Surface treatment**: hot-dip galvanizing (average zinc layer ≥600g/㎡), epoxy resin spraying (thickness 60-80μm) or black blank (bare steel).
Implementation standards: GB/T 706-2016, JIS G3192, ASTM A36.
Load capacity: Taking 100×100×10mm angle steel as an example, the axial bearing pressure is ≥210kN, and the static bending strength is ≥45kN·m.
