Colored stone tile is a kind of innovative roofing material combining metal substrate and natural stone particles. The substrate is made of aluminum-plated zinc steel plate (coating composition 55% aluminum,43.4% zinc, 1.6% silicon), the surface is bonded with natural colored sand (basalt/quartz sand) by special process, and the high temperature sintering (200-300℃) forms a lightweight composite plate imitating traditional tiles.

Core production step

1.Substrate Pretreatment

● Aluminized zinc steel plate

Substrate thickness 0.4-0.6mm (common AZ150 coating, double-sided coating 150g/㎡), with excellent corrosion resistance (salt spray test ≥1000 hours without red rust)

● Cleaning passivation

After alkaline degreasing (residual oil ≤30mg/m²), chromium treatment generates conversion film (film thickness 0.5-1.2μm)

2.Stone Coating

● Binder

epoxy resin or acrylic adhesive, coating amount 200-300g/㎡

● Colored sand particles

natural basalt or stained quartz sand with particle size 0.3-1.2mm, color stability up to ΔE≤3.0 (QUV 3000 hours)

3.Curing

● In the continuous baking oven, heating at 200-250℃ for 10-15 minutes, so that the binder is completely cured, forming a dense protective layer

4.Surface Protection

● Optional transparent fluorocarbon topcoat for enhanced stain resistance and UV protection

Product advantage
