Product Description

Flat steel, refers to 12-300mm wide, 3-60mm thick, rectangular section and slightly with a blunt edge of steel. Flat steel can be finished steel, can also be used as a blank for welding pipe and thin slab for rolling sheet. Main uses: flat steel as a finished material can be used for hoop iron, tools and mechanical parts, as building frame structure, escalator.

Low carbon flat steel compared to traditional steel plates

1. Special product specifications. The thickness is 8-50mm, the width is 150-625mm, the length is 5-15m, and the product specifications are denser, which can meet the needs of users. It can be used directly instead of the middle plate without cutting and can be welded directly.

2. The surface of the product is smooth. The high-pressure water descaling process is used twice in the process to ensure the surface of the steel is smooth and clean.

3. The sides are vertical, and the rhomboids are clear. The two vertical rollings in finishing rolling ensure good verticality on both sides, clear corners, and good surface quality on the sides.

4. The size of the product is accurate, three points difference, the same level difference is better than the steel plate standard; the product is straight and the shape is good. Finishing rolling adopts continuous rolling process and automatic looper automatic control to ensure that no steel is piled and no steel is pulled. The product has high dimensional accuracy. The tolerance range, three point difference, same strip difference, sickle bend, and other parameters are better than the medium plate. Good degree. Cold-shear cutting, high precision in length sizing.

5. The material of the product adopts the national standard, which is the same as the steel plate. Quality and technical standards are organized according to YB / T4212-2010 standards (Q345B / Q235B refer to GB / T1591-94 and GB / T700-06 standards, respectively)
