Hot rolled, cold rolled, galvanized and stainless steel coils are originally rolled up with natural bending and unfixed sizes, which cannot be directly applied to steel structure construction, mechanical manufacturing, precision stamping and overseas project delivery. Leveling, slitting and cut-to-length shearing are the most fundamental and widely used deep-processing procedures in steel export business, ensuring flat surface, accurate dimension and excellent construction performance.
1. Steel Leveling Process
Leveling is used to flatten curved steel coils and eliminate internal stress. Steel coils pass through multiple groups of straightening rollers to remove camber, wave edges and surface warping. The processed steel plates feature uniform flatness and stable mechanical performance, effectively avoiding deformation and cracking during bending, welding and punching. This process is suitable for carbon steel, stainless steel and galvanized steel, serving as an essential procedure for standard export steel plates.
2. Steel Coil Slitting Process
Slitting is a longitudinal cutting technology. Wide original coils are cut into narrow strips by professional circular slitting machines according to customized width requirements. The cutting edge is smooth, burr-free and distortion-free with high dimensional accuracy. Slit strips are ideal materials for guardrail plates, pipe making, precision stamping parts and hardware accessories, perfectly matching large-batch standardized export orders.
3. Cut-to-Length Shearing Process
Transverse shearing cuts flattened steel sheets and narrow strips into customized fixed lengths. We support non-standard size processing with neat and vertical cutting surfaces, no scratches or plate deformation. Fine processing such as edge trimming and deburring is available to meet strict standards of high-end equipment manufacturing and precision export components.
4. Integrated Processing & Export Advantages
We provide one-stop integrated processing: uncoiling, leveling, slitting, fixed-length shearing and export packaging. Strict tolerance control and surface quality inspection ensure stable and reliable finished products. Compared with raw coils, processed steel plates can be directly used for construction and production, greatly saving processing time and labor costs for clients. All products comply with GB, ASTM and EN standards, suitable for container shipment and overseas engineering acceptance.
