Pickled plate is a type of product manufactured from high-quality hot-rolled sheet. The pickling process removes the surface oxide layer before the edges are cut and the product is finished.

Pickled plate is a product made from high-quality hot-rolled sheet. The pickling process removes surface oxidation, edges are trimmed, and the product is finished. Its surface quality and usability fall between hot-rolled and cold-rolled plate, making it an ideal substitute for both.

Production Process

The pickled plate production process includes these steps:

● Raw material selection: High-quality hot-rolled sheet is used.

● Pickling treatment: Hot-rolled sheet is immersed in hydrochloric acid to remove iron oxide via chemical reaction, resulting in a clean surface.

● Edge cutting and finishing: Burr and uneven edges are removed. Further leveling adjusts surface roughness.

Performance Characteristics

Pickled plate has these key characteristics:

● Good surface quality: Removal of iron oxide results in a surface quality superior to hot-rolled plate, beneficial for welding, oiling, and painting.

● High dimensional accuracy: Leveling improves flatness and reduces unevenness deviation.

● High finish: Improved surface finish and appearance.

● High cost-effectiveness: Compared to cold-rolled plate, pickled plate offers significant cost savings while maintaining surface quality.

Applications

Pickled plate is widely used in various fields:

● Automobile industry: Primarily used in chassis systems (beams, sub-beams), wheels (rims, wheel radials), cab interior and compartment panels.

● Mechanical industry: Used in textile and mining machinery, fans, and general machinery. Also used in compressors, brackets, water heater liners, etc.

● Other applications: Chemical oil drums, bicycle parts, welded pipes, electrical cabinets, highway guardrails, supermarket and warehouse shelving, fences, iron ladders, and various stamped parts.
