Test method
① Tensile testing methods. Common standard test methods include GB/T 228-87, JIS Z 2201, JIS Z 2241, ASTM A370, GOST 1497, BS 18, DIN 50145, and others; ② Bend testing methods. Common standard test methods include GB/T 232-88, JIS Z 2204, JIS Z 2248, ASTM E 290, GOST 14019, DIN 50111, and others. [2]
Performance Metrics
The primary test items for evaluating the performance of angle steel are tensile testing and bending testing. The relevant parameters include yield strength, tensile strength, elongation, and bend‑test pass criteria. Specifications and weight calculation methods for unequal‑leg angle steel are as follows:
Weight per meter = 0.00785 × (flange width + flange width − flange thickness) × flange thickness
