Stucco Pattern Steel Roll Forming Material Guide: Embossed Coil Sizes & Uses

Stucco Pattern Steel Roll Forming Material

1. Overview of Stucco Pattern Steel in Roll Forming

Stucco pattern steel is an embossed steel material featuring a fine, irregular textured surface designed to improve appearance, reduce glare, and increase stiffness.

In roll forming, stucco pattern steel is widely used for roofing panels, wall cladding, ceiling systems, and decorative architectural components.

Compared to smooth steel, stucco embossed material significantly reduces oil canning, improves visual consistency, and enhances durability.

2. Material Composition & Structure

Stucco pattern steel is typically:

Galvanized steel (GI)
Galvalume / Aluzinc steel
Pre-painted steel (PPGI / PPGL)
Cold rolled steel

Structure

Steel base material
Optional coating (zinc, aluminum-zinc, paint)
Stucco embossed surface pattern

12. Pricing Guide

Typical global pricing:

Low: $750–$1000 per ton
Medium: $1000–$1500 per ton
High: $1500–$2100+ per ton

Factors affecting price:

Base material

13. Comparison with Other Materials

Stucco Steel vs Smooth Steel

Stucco = better aesthetics, less oil canning
Smooth = cheaper

Stucco Steel vs Embossed Steel

Stucco = specific fine pattern
Embossed = multiple pattern types

Stucco Steel vs Textured Paint

Stucco = physical texture
Paint = visual effect only

14. Best Industries Using Stucco Pattern Steel

Roofing and cladding
Construction
HVAC manufacturing
Architecture and design
Industrial panel production

15. How to Choose Stucco Pattern Steel

Choose Stucco Pattern Steel When:

Oil canning must be reduced
Visual consistency required
Roofing or cladding applications
Light reflection needs to be reduced

Avoid When:

Smooth finish required
Precision forming needed
Decorative mirror finishes required
