Flat steel

Advantages of flat steel

Flat steel is rolled with negative deviation, but delivered according to the actual weight, and the utilization rate is 1 ~ 5 percentage points higher than that of steel plate.

Flat steel can be produced with fixed thickness, width and length according to the needs of users, which reduces cutting, saves processes, reduces the consumption of labor and materials, reduces the processing loss of raw materials, and saves time, labor and materials. The products have been used in steel structure manufacturing, machinery manufacturing, automobile industry, mining machinery, hoisting machinery and other industries.

contrast

Special product specifications. The thickness is 8 ~ 50mm, the width is 150-625mm, the length is 5-15m, and the product specification span is dense, which can meet the needs of users. Instead of the medium plate, it can be directly welded without cutting.

The surface of the product is smooth. High pressure water descaling process is adopted for the second time in the process to ensure that the steel surface is smooth.

Both sides are vertical, and the water caltrop is clear. The two pass vertical rolling in finish rolling ensures good perpendicularity, clear angle and good surface quality of both sides.

The scale of the product is accurate, with three-point difference, and the difference at the same level is better than the steel plate standard; The product is straight and good in shape. The finish rolling adopts continuous rolling process and automatic looper automatic control to ensure that there is no steel stacking and drawing. The product has high dimensional accuracy. The parameters such as tolerance range, three-point difference, same strip difference and sickle bending are better than the medium plate, and the flatness of the plate is good. Cold shear, high length sizing accuracy.

The product material adopts the national standard, which is the same as the steel plate. The quality and technical standards are organized according to Yb / t4212-2010 (Q345B / Q235B refer to GB / t1591-94 and GB / t700-06 respectively).
