Hot-rolled steel coil product introduction: Hot-rolled steel coil and strip products are made of slab (mainly continuous casting slab) as raw material, and are made into strip steel by rough rolling unit and finishing rolling unit after heating. The hot steel strip coming out of the last rolling mill of finishing rolling is cooled to the set temperature by laminar flow, rolled into steel strip coil by coiler, and the cooled steel strip coil.
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.
