What are the advantages of sand coated metal roof?

I. Performance Advantages

Waterproof & Seepage-proof

Composed of metal base, composite waterproof layer and colored stone coating, it features excellent overall tightness. Resistant to rain erosion, it effectively prevents water leakage and seepage, ideal for rainy regions.

Weather Resistance & Anti-aging

The colored stone top layer resists UV rays, extreme temperatures, wind, frost, rain and snow. It has a service life of over 50 years under normal use, with no easy fading or cracking.

Fire Retardant

The metal substrate is non-combustible with superior fire rating, much safer than traditional clay tiles and asphalt shingles.

Sound Insulation & Noise Reduction

The granular stone surface greatly weakens noise caused by raindrops and hailstones, delivering a quieter indoor environment than ordinary metal roofing sheets.

Wind & Earthquake Resistance

Lightweight and high in toughness, the tiles are firmly installed. They stand well against strong winds and earthquakes, and will not be blown off easily.

Anti-corrosion & Rust Prevention

The base material is treated with galvanization or galvalume coating plus anti-rust paint. With surface protection, it stays rust-free even in coastal, humid and acid rain areas.

II. Installation & Practical Advantages

Light Weight

It weighs only 1/6 to 1/3 of traditional clay tiles, reducing load on roof structures. Suitable for old building renovation and light steel buildings.

Fast Installation

Large-sized panels and tiles allow easy assembly, shortening construction time and cutting labor & overall costs.

Strong Roof Adaptability

Applicable to steep-slope, curved and irregular-shaped roofs. Flexible for architectural styling and easy for reconstruction & renovation.

III. Appearance & Maintenance

Decorative Effect

Available in diverse natural-looking colors with stone or clay tile texture. Elegant and stylish to enhance building aesthetics.

Low Maintenance

The surface resists dirt and moss growth. Almost no daily upkeep is required, leading to extremely low long-term maintenance costs.

IV. Environmental Protection & Safety

Non-toxic and eco-friendly with no harmful substance emission. Fully recyclable and classified as a green building material.
