To put it simply, after a steel billet is heated (that is, the red hot steel block on TV), it is rolled several times, then trimmed, and corrected into a steel plate. This is called hot rolling.

The hot-rolled steel plate products produced by Zhengde have excellent properties such as high strength, good toughness, easy processing and good weldability, so they are widely used in manufacturing industries such as ships, automobiles, bridges, construction, machinery, and pressure vessels.
Spot inventory of steel plates with various material properties: ordinary carbon structural steel plates, low alloy steel plates, alloy steel plates, wear-resistant steel plates, steel plates for cold forming, structural steel plates, automotive structural steel plates, steel plates for corrosion-resistant structures, mechanical structures Steel plates, steel plates for welded gas cylinders and pressure vessels, steel plates for pipelines, etc.
The surface quality is good. Compared with ordinary hot-rolled sheets, Zhengde hot-rolled sheets have removed the surface oxide scale, improved the surface quality of steel, and are convenient for welding, oiling and painting.
The dimensional accuracy is high, and after leveling, the plate shape can be changed to a certain extent, thereby reducing the deviation of unevenness. Improved surface finish for enhanced appearance
Relying on Zhengde's sufficient steel plate resources, it reduces the pressure on customers' inventory. It can be cut according to drawings, or directly cut into graphics required by customers, such as circles, rectangles, flanges, bearing housings, rolling mill racks, and rolling mill arches, etc. The cutting precision is high. , the incision is smooth and tidy, and the machining allowance is small.
Quality first: production and inspection in strict accordance with production standards;Price advantage: discounts based on real market prices;
Transaction security: There will be no loss of customer funds;
After-sales guarantee: the customer's problem is our problem;
Long-term cooperation: quality assurance, price advantage, sincere service can last for a long time.
