Carbon Steel Flat Bar
Flat steel refers to steel with a width of 12-300mm, a thickness of 3-60mm, a rectangular cross-section and slightly blunt edges. Flat steel can be finished steel, and can also be used as blanks for welded pipes and thin slabs for stacked thin plates. Main application: Flat steel can be used as a finished material to make hoop iron, tools and mechanical parts, and it can be used as a structural part of a house frame and an escalator in a building.

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

2. The surface of the product is smooth. In the process, the high-pressure water descaling process is used for the second time to ensure the smooth surface of the steel.

3. The two sides are vertical and the water chestnut is clear. The second vertical rolling in the finish rolling ensures good verticality of both sides, clear corners and good edge surface quality.

4. The size of the product is accurate, with a difference of three points, and the difference of the same level is better than the steel plate standard; the product is straight and the shape is good. The continuous rolling process is adopted for the finishing rolling, and the automatic control of the looper ensures that no steel is piled up or pulled. good degree. Cold shearing, high precision in length determination. The material of the product adopts the national standard, which is the same as the steel plate.

5. The quality and technical standards are organized according to the YB/T4212-2010 standard (Q345B/Q235B refer to GB/T1591-94 and GB/T700-06 respectively).

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

7. Flat steel can be produced in a fixed thickness, fixed width, and fixed length according to user needs, which reduces cutting for users, saves processes, reduces labor and material consumption, and also reduces processing loss of raw materials, saving time and effort , save material. The products have been professionally used in steel structure manufacturing, machinery manufacturing, automobile industry, mining machinery, hoisting machinery and other industrial materials.
