PVDF Color Coated Steel Coil with Z90 Zinc Coating for Building Roofing and Wall Cladding Applications

１．Product Overview

PVDF Color Coated Steel Coil is a pre-painted steel product manufactured according to JIS G3312 standards for building and architectural applications. The product combines a zinc-coated steel substrate with a durable organic coating system to provide corrosion resistance, weatherability, and decorative appearance.

With a 900mm width, 0.35mm thickness, and Z90 zinc coating, the coil is suitable for roofing systems, wall cladding panels, and light-gauge building components where long-term outdoor performance is required.

２．Technical Solution

The steel substrate is protected by a Z90 zinc coating equivalent to 100g/m², providing corrosion resistance for exterior applications.

The coating system consists of a 15–20μm top coating with an additional 5μm primer layer, while the reverse side uses a 5–7μm coating with a 5μm primer. This structure improves adhesion, weather resistance, and coating durability.

RAL color options allow the product to meet architectural design requirements while maintaining color consistency throughout production batches.
