UV Resistant Steel Roll Forming Material Guide: Coatings, Coil Sizes & Performance

UV Resistant Steel Roll Forming Material

1. Overview of UV Resistant Steel in Roll Forming

UV resistant steel is a coated metal designed to withstand prolonged exposure to sunlight without fading, chalking, or coating degradation. It is widely used in outdoor applications where durability and long-term appearance are critical.

In roll forming, UV resistant steel is used for roofing panels, wall cladding, façade systems, and exterior structures.

Compared to standard painted steel, UV resistant materials provide longer lifespan, improved color retention, and better weather resistance.

2. Material Composition & Structure

UV resistant steel typically consists of:

Steel base (galvanized or galvalume)
Metallic coating (zinc or aluminum-zinc)
Primer layer
UV resistant top coating

Typical Coating Systems

Polyester (basic UV resistance)
SMP (Silicone Modified Polyester)
PVDF (high-performance UV resistance)

12. Pricing Guide

Typical global pricing:

Low: $700–$1000 per ton (PE coating)
Medium: $1000–$1600 per ton (SMP)
High: $1600–$2500+ per ton (PVDF)

Factors affecting price:

Coating type
Base material (GI vs GL)
Thickness
Supplier origin

13. Comparison with Other Materials

UV Resistant Steel vs Standard PPGI

UV resistant = longer lifespan
Standard PPGI = lower cost

UV Resistant Steel vs Galvalume

UV resistant = coated finish
Galvalume = metallic coating only

SMP vs PVDF

SMP = mid-range
PVDF = premium performance
