Our prime quality high strength structural stel plates retain the acidic attacks in tough climatic environments. These steel plates are heat-treated at very high temperatures of the heat; further, these are cold and hot workable steel. Our plates and sheets have excellent superior weldability. A572 Gr.50 dual certified plates GB/T 4171 grade Q235NH alloy steel sheet undergo many tests after the production such as corrosion test, pitting corrosion test, flattening test, flaring test, radiographic test and so on.

The refining process of GB/T 4171 grade Q235NH alloy steel sheet, wear-resistant clad plate can improve the purity of liquid steel and meet the requirements of continuous casting for the composition and temperature of molten steel, and meet the quality requirements of special steel, ordinary steel and cast steel in industrial production. Because of its simple structure, convenient operation, diversified functions and low investment, it has been widely used and become one of the main out-of-furnace refining methods for smelting pure steel in the iron and steel industry.

"In year 2014, we participate Bangladesh national railway tender for steel plate making train carriage. We finally got the order 1000 tons and it took us 40 days to produce all the plates. The client gave very high comments to our service and GB/T 4171 grade Q235NH alloy steel sheet product quality.In year 2015, we won another tender for 1200 tons B480GNQR steel coils in Bangladesh, which you can find in the steel coil part."
