ASTM A755 Wood Grain Prepainted Steel Coil Used For Indoor Decoration Wall

Wood grain pre-painted steel coil is a high-performance coated steel product featuring realistic

wood patterns printed on its surface. It combines the strength of metal with the aesthetic appeal

of natural wood, making it ideal for architectural decoration, furniture, and commercial applications.

Structure & Composition

Base Material:

Cold-rolled steel (CR), galvanized steel (GI), or aluminum-zinc alloy-coated steel (AZ, e.g., Galvalume),

with thickness typically ranging from 0.3–1.2mm.

Coating System (from top to bottom):

Wood Grain Layer: Applied via thermal transfer or digital printing (e.g., teak, oak, walnut patterns).

Topcoat: Polyester (PE), PVDF, or silicon-modified polyester (SMP) for weather resistance.

Primer: Epoxy or polyurethane for adhesion and anti-corrosion.

Chemical Conversion Layer: Chromate or phosphate treatment for rust prevention.

Key Features

Authentic Wood Aesthetics:

High-resolution printing/3D embossing replicates natural wood grains without drawbacks like cracking or termite damage.

Superior Durability:

Corrosion Resistance: Base metal (e.g., AZ) + coating extends service life to 15–25 years (vs. 5–10 years for natural wood).

Weather Resistance: PVDF topcoat ensures ΔE<5 color shift after 10+ years outdoors.

Lightweight & High Strength:

1/3 the weight of solid wood but with excellent bendability for large-span applications (e.g., façades).

Eco-Friendly:

Formaldehyde-free, recyclable, and compliant with LEED/GREEN BUILDING standards.

Applications

♦ Architecture:

Exterior cladding, interior wall panels, roofing tiles, trim.

♦ Furniture & Retail:

Cabinet surfaces, decorative partitions, hotel/office interiors.

♦ Industrial:

Elevator interiors, prefab houses, signage.
