Steel strip is a branch of steel plate. Steel strip is a kind of narrow and long steel plate, also known as strip steel, S690QL material properties produced by various steel rolling enterprises to meet the needs of different industrial departments and industrial production of various metal or mechanical products. The width of steel strip is within 1300mm, and the length is slightly different according to the size of each roll. Generally, S690QL material properties steel strip is supplied in coils, with the advantages of high dimensional accuracy, good surface quality, easy processing and material saving. The steel strip is a kind of steel with large output, wide use and many varieties.

Thin steel 5mm to 10mm S690QL material properties stock list 5*2550*9200, 5.5*2500*10000, 5*2670*8500, 7*2260*8600, 6*2510*10400, 5*1860*12000, 8*2000*10000, 7*2000*8000, 8*2350*8600, 10*2500*8500, 8*2540*8200, 9*2500*9500, 10*2510*10600, 8*2400*6000, 10*2550*8500, 10*2800*6300, 10*1600*12000, 10*2000*6500, 10*2650*8300, 10*2800*6150, 10*2000*8600, 10*2150*5500.

The steel such as S690QL material properties delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can be stored in the open air. However, this layer of oxide scale also makes the hot-rolled steel surface rough and the size fluctuates greatly. Therefore, the steel with smooth surface, accurate size and good mechanical properties is required to be produced by using hot-rolled semi-finished products or finished products as raw materials and then cold rolling.
