GB series angle steel: in accordance with the Chinese national standard (GB/T) 706-2016, which specifies the size, tolerance, chemical composition and mechanical properties of angle steel.

National standard angle steel mainly uses ordinary steel, and the strength and toughness of both equal-leg angle steel and unequal-leg angle steel are relatively low.

National standard angle steel mainly adopts surface treatment methods such as hot-dip galvanizing or painting, and its corrosion resistance and service life are relatively poor.

National standard angle steel is suitable for general engineering fields and building structures, and its scope of use is relatively wide.

The allowable deviation of the steel weight should not exceed ±5%, and the theoretical weight is calculated based on a density of 7.85g/cm3. The weight deviation (%) is calculated as follows. The allowable weight deviation applies to a batch of the same size and a mass exceeding 1 ton, and also applies when the mass of a batch of the same size is not greater than 1 ton but the number of roots is greater than 10.

Weight deviation = (actual weight - theoretical weight) ÷ theoretical weight × 100%

The cross-sectional area calculation formula of equilateral angle steel:

d(2b-d)+0.215(r2-2r12)
