Due to these advantages, color coated coils are widely used across various sectors, including construction, home appliances, and automotive manufacturing, and have become essential high-performance materials in modern industry.
Spiral pipe, also known as spiral steel pipe or spiral welded pipe, is made by rolling low-carbon structural steel or low-alloy structural steel strip into a pipe blank at a certain angle of the spiral line (called forming angle), and then welding the pipe seam together. It can produce large-diameter steel pipes with narrower strip steel.
PPGI (Pre-Painted Galvanized Iron) coil is a high-quality steel product produced by coating steel sheets with one or more layers of organic paint, followed by high-temperature baking to cure the coating.
The zinc coating gives the sheet a silver-gray appearance, and depending on the manufacturing process, it may also display a spangled pattern that enhances its visual appeal.
