PVDF Coated Steel Roll Forming Material Guide: Premium Coating, Coil Sizes & Applications

PVDF Coated Steel Roll Forming Material (Polyvinylidene Fluoride)

1. Overview of PVDF Coated Steel in Roll Forming

PVDF (Polyvinylidene Fluoride) coated steel is a high-performance pre-painted steel material designed for maximum durability, UV resistance, and long-term color stability.

It is considered the premium coating system used in roll forming, especially for architectural, commercial, and high-end industrial applications. PVDF coatings are typically applied to both galvanized steel (PPGI) and Aluzinc steel (PPGL), with PPGL often preferred for superior corrosion resistance.

In roll forming, PVDF coated steel is used where long lifespan (20–30+ years) and minimal maintenance are critical.

2. Material Composition & Structure

PVDF coated steel consists of:

Steel base (cold rolled steel)
Zinc or Aluzinc coating
Chemical pre-treatment
Primer layer
PVDF topcoat
Backing coat
