Our compay export 1000 tons mild steel plates q235b ever month

mild steel plates q235b and so on steel structure engineering steel has good plasticity, which can make the structure have obvious deformation before being destroyed, so as to avoid brittle failure of structure. The good plasticity of steel can adjust the local peak stress to redistribute the stress, and improve the ductility of components, so as to improve the seismic capacity of the structure. The impact toughness of mild steel plates q235b and so on steel structure engineering steel is good, which can improve the ability of resisting dynamic load and avoid the occurrence of cracks and brittle fracture.

BBN STEEL supply various size of plate product mild steel plates q235b Size stock: 16*1555*11400, 12.7*3316*10500, 12.7*2438.4*12192, 23*2330*11300, 12.7*2518*11380, 6.5*2450*12500, 18*1860*12000, 12.7*2515*12000, 9*2440*12500, 15.1*1550*10400, 12*2680*12000, 12*2520*12000, 18*2020*12000, 11*2365*12000, 14*3470*12000, 12.7*2518*11380, 18*1700*12000, 9.2*2530*12000, 12*2680*12000, 68*2350*7500.

A572 grade can be divided into five levels: mild steel plates q235b, A572 grade 42 (290), 50 (345), 55 (380) for riveted, bolted or welded structural parts; A572 grade 60 (415) and 65 (450) for bridge riveted and bolted structural parts or welded structural parts for other purposes. Chemical composition of A572 Gr50 steel: C: ≤ 0.20, Si: ≤ 0.40, Mn: ≤ 1.50, P: ≤ 0.04, S: ≤ 0.05, Nb: ≤ 0.005-0.05.

In recent years, after the completion of large-scale, high-speed and automation of steel rolling technology and equipment in the world, the rapid development of mild steel plates q235b high-precision rolling technology with the goal of improving product quality, expanding varieties, saving energy and reducing consumption, and increasing benefits. For example, in 2013, Bebon Iron and Steel's 4300 mm rolling mill, 5000 mm rolling mill and 3500 mm furnace coil rolling mill introduced foreign technology to further upgrade the company's mild steel plates q235b technical equipment.
