Product Description
Zhengde Hot rolled steel is steel that has been roll-pressed at very high temperatures-over 1,700, which is above the re-crystallization temperature for most steels. This makes the steel easier to form, and resulting in products that are easier to work with. To process hot rolled steel, manufacturers first start with a large, rectangular length of metal, called a billet. The billet is heated and then sent for pre-processing, where it is flattened into a large roll. From there, it is kept at a high temperature and run through a series of rollers to achieve its finished dimensions. Steel shrinks slightly as it cools. Since hot rolled steel is cooled after processing, there is less control over its final shape, making it less suitable for precision applications. Hot rolled steel is often used in applications where minutely specific dimensions aren't crucial.

Our Advantages
High Strength
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.
Adequate inventory
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.
Attention to detail
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
Provide deep processing
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.
