Good surface quality: after removing surface iron oxide, the surface quality of pickled plate is better than that of hot rolled plate, which is convenient for welding, oiling and painting.

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

Production Process

The production process of pickled plate includes the following steps:

● Selection of raw materials: high-quality hot-rolled sheet is used.

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

● Edge cutting and finishing: Burrs and uneven edges are removed, and further leveling is done to achieve the desired surface roughness.

Performance Characteristics

Pickled plate has the following characteristics:

● Good surface quality: After iron oxide removal, the surface quality is superior to hot-rolled plate, facilitating welding, oiling, and painting.

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

● 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 interiors, and compartment panels.

● Mechanical industry: Used in textile machinery, mining machinery, fans, and general-purpose machinery. Also used in compressor shells, 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.
