PVC Coated Steel Roll Forming Material Guide: Coil Sizes, Properties & Uses

PVC Coated Steel Roll Forming Material

1. Overview of PVC Coated Steel in Roll Forming

PVC coated steel is a steel substrate (usually galvanized or cold rolled steel) coated with a thick layer of polyvinyl chloride (PVC). This coating provides excellent corrosion resistance, durability, and a smooth or textured finish.

In roll forming, PVC coated steel is widely used for roofing panels, wall cladding, gutters, drainage systems, and industrial applications, especially in harsh environments.

Compared to standard painted steel (PPGI), PVC coated steel offers thicker protection and superior resistance to chemicals and abrasion.

2. Material Composition & Structure

PVC coated steel consists of multiple layers:

Steel base (GI or CR steel)
Zinc coating (if galvanized)
Primer layer
PVC top coating (main protective layer)

Layer Structure (VERY IMPORTANT)

Steel core
Zinc coating (optional)
Adhesion primer
PVC coating (100–200 microns typical)

13. Comparison with Other Materials

PVC Coated Steel vs PPGI

PVC = thicker coating
PPGI = cheaper

PVC Coated Steel vs Galvanized Steel

PVC = better corrosion protection
GI = lower cost

PVC Coated Steel vs Plastisol Steel

Very similar (plastisol is PVC-based)
Plastisol often thicker and softer
