Product Features
- Durability: The pre-painted coating also adds an extra layer of protection against harsh environmental elements like UV rays, salt, and acidic rain.
- Durability: High-quality fencing wire is designed to withstand harsh weather conditions (rain, wind, UV rays) and physical wear. Galvanized and PVC-coated wires are particularly resistant to corrosion and rust, which prolongs their lifespan.
- Wide Range of Colors PPGI sheets come in a variety of vibrant colors and finishes, including matte, glossy, and textured. This allows for better aesthetic integration into different architectural designs.
- Weather Resistance Coatings like PVDF (Polyvinylidene Fluoride) and SMP (Silicone Modified Polyester) offer excellent resistance to UV rays, preventing the sheet from fading over time.
Manufacturing Process
- Steel Coil Preparation: The process starts with cold-rolled steel coils (also called base metal), which are cleaned and pre-treated to remove any impurities such as oil, dirt, and rust.
- Hot-Dip Galvanization: In this step, the steel coils are passed through a molten zinc bath at a temperature of around 450°C. The zinc coating bonds with the steel through a process called diffusion.
- Chromium Passivation: After the galvanizing process, the steel coil surface is treated with a chromium-based solution or other passivating agents. This layer enhances the corrosion resistance and prevents the zinc coating from deteriorating over time.
