Product Description
Zhengde Color Prepainted Galvanized PPGI Steel Coils is a product made of cold rolled steel plate and galvanized steel plate by surface pretreatment (degreasing, cleaning, chemical conversion), continuous coating (roll coating), baking and cooling. Coated steel sheet has light weight, beautiful appearance, good corrosion resistance and can be processed directly. It provides a new raw material for construction, shipbuilding, vehicle manufacturing, household electrical appliances, electrical industry, etc. It has played a good role in replacing wood with steel, efficient construction, energy saving, pollution prevention and other good results | Location | category | value |

Our Advantages
Complete range
For the use of color steel coils, we have to choose different types of color steel coils to manufacture different PPGI. Speaking of this, I have to briefly introduce the types of color steel coils, which are divided into five categories. That is, home appliances, optical materials, decorative materials, building materials, and packaging. Among them, the production process of color steel coils for home appliances is the most delicate and perfect.
Good performance
Zhengde color coated steel plate refers to the coating product obtained by applying organic paint to the surface of thin steel plate. PPGI has good anti-corrosion and decorative properties, as well as the good formability and processing properties of organic polymers and steel plates.
5S management
Before PPGI production, each post cleans the surrounding environment, ground sanitation, equipment spot inspection and each roller surface that directly affects the surface quality of the product in the working area according to the "Workshop 5S Management System" to ensure personal safety. At the same time, prepare tools, auxiliary materials, raw materials, etc. within the specified time. Ensure that the ground in the work area is free from dust, water and oil, ensure that the equipment is in the best condition and that the materials are used correctly.
Strictly check
PPGI image defects, surface defects, trace defects, edge defects, gold plating defects, size defects, coating defects, uneven defects, contamination defects, coating uneven defects, process defects, coating surface defects, physical property defects.
Quality first: production and inspection in strict accordance with production standards;
Price advantage: discounts based on real market prices;
