Color Stone Coated Metal Roof Tile

Galvalume steel sheet is composed of 55% aluminum, 43.4% zinc, and 1.6% silicon. The quality of the galvalume steel sheet directly determines the service life of the product. The quality of galvalume steel sheets on the market varies. We use high-quality galvalume steel sheets. The galvalume surface has a fingerprint-resistant coating. The fingerprint-resistant coating protects the galvalume layer. At the same time, the fingerprint-resistant coating can make the galvalume steel sheet and the colored sand particles bond better. The color of the fingerprint-resistant coating is colorless transparent and light green.

Alu-zinc steel sheet has excellent corrosion resistance and heat resistance.

Aluminum has a protective function. When zinc is worn, aluminum forms a dense layer of aluminum oxide to prevent corrosion-resistant substances from further corroding the interior. Therefore, the Aluzinc steel sheet has excellent corrosion resistance.
Alu-zinc steel sheet has good heat resistance and can withstand high temperatures of 300 degrees. The heat reflectivity of an Alu-zinc steel sheet is very high, twice that of an ordinary galvanized steel sheet. It is often used as a heat insulation material. Our African market has a great demand for aluminum products and Alu-zinc steel sheet products.

Colored sand is the decorative layer and base protective layer of metal tiles. It is made of particles of a certain size through high-tech coloring technology and high-temperature baking. It has more than ten colors, is resistant to ultraviolet radiation, can reduce the noise caused by rain on metal tiles, and makes the color steel tiles rich solemn, and more decorative, which is not available in general color corrugated steel plates and cannot be compared.
The colored sand we use is sintered colored sand. Sintered colored sand is made of mineral particles as raw materials, added with inorganic pigments and special coatings, and sintered at high temperatures.

Acrylic resin is the key material for bonding steel plates and colored sand. It also serves as a protective layer on the surface of the sand, preventing rainwater from leaking into the details and extending the life of the sand color. Glue is one of the main raw materials, divided into base glue and surface glue, commonly known as: acrylic resin glue, the main function is to effectively bond with steel plates and colored sand. The characteristics of the glue are:

1. Good corrosion resistance and UV resistance.

2. High hardness, good compatibility, and excellent adhesion to various metal plates and concrete;

3. Good matching, fast drying speed, strong sand bonding ability, and excellent water resistance.
