There are several polishing methods for weathering steel plate

1. Grinding and polishing
Its advantages are good flatness and high gloss of weathering steel plate after production and processing. Its defects are high labor efficiency, serious environmental pollution, and complex weather resistant steel plate can not be produced and processed, and its gloss can not be consistent, gloss maintenance time is not long, hair blocking, corrosion. It is suitable to produce weathering steel plate with simple processing.

2. Chemical polishing
Its advantage is less investment in production equipment projects, complex parts can also be polished, and faster, high efficiency, good corrosion resistance. Its defects are poor gloss, steam body overflow, ventilation and cooling equipment must be provided, and temperature rise is difficult. Suitable for small batch production of complicated weathering steel plate and small and medium pipe fittings, the gloss requirement is not high.

3. Electrochemical polishing
Its advantages are long gloss of mirror glass, stable processing technology, less environmental pollution, low cost and good corrosion resistance. Its defects are strong pollution control, large one-time project investment of production equipment, complicated parts need work clothes and auxiliary electrical level, and many production and manufacturing also need desuperheating equipment. Suitable for large-scale production of weathering steel plate, the key is used in high-end weathering steel plate, import and export weathering steel plate, weathering steel plate with dimensional tolerance, its production process is stable, and the actual operation is simple.
