Based on the advantages of A709 grade HPS70W bridge steel plate steel resources in domestic market and good reputation, combining with the huge international market demand for steel products, our company started the international business in 2010 and successfully being approved and certified by ISO9001:2008, the Registration number is 626014Q11531R0S. With the quality steel A709 grade HPS70W bridge steel plate products and professional service, our company was award the international acclaim from infrastructure, shipbuilding, petroleum industry etc., and gradually grow into a bright star in the steel export industry .
The bridge steel plate A709 grade HPS70W bridge steel plate produced by BBN company has pure steel, flat and smooth plate surface, small difference between plates, -40 ℃ impact value and aging impact value are stable, and the margin is large. Bridge steel plates can be controlled by rolling, cooling, normalizing, and tempering organize production with different production processes. This bridge steel A709 grade HPS70W bridge steel plate is widely used in the manufacture of large railway bridges and highway bridges.
Our company produces ordinary carbon steel A709 grade HPS70W bridge steel plate with high strength and good plasticity and toughness. Due to the effect of alloy elements, its strength is 25% - 50% higher than that of ordinary carbon steel, its elongation is 15% - 23%, and its impact toughness at room temperature is higher than 60j / cm 2. We have a A709 grade HPS70W bridge steel plate production line specializing in the production of ordinary carbon steel plate, and strictly control its quality.
Steel production and rolling technology and equipment also pursue the continuity between processes, such as the continuous A709 grade HPS70W bridge steel plate process between continuous casting and rolling mills, continuous casting slabs hot transfer hot charging, increased direct rolling, and continuous cold rolling processes. The development of controlled rolling and controlled cooling technology that combines rolling and heat treatment has played a huge role in improving the properties of rolled materials.
