Colored stone metal tile

Colored stone metal tile is produced by high-tech, with 55% galvanized steel plate with excellent anti-corrosion performance as the substrate, acrylic resin with strong weather resistance as adhesive, and a new type of high-grade roofing material with colored natural gravel as the surface layer . Because of its beauty, lightness, durability and environmental protection, it has become the mainstream product of international roofing materials in recent years, and some high-end buildings in China have also begun to use it.

It is composed of galvanized steel plate as the base material, colored sand, primer and acrylic resin. (Take the colored stone metal tiles of South Korea Feiruifu Co., Ltd. as an example)

1. Acrylic protective layer

2. Italian basalt colored stone particles

3. Acrylic layer

4. Epoxy primer protective layer

5. Galvalume

6. Substrate steel plate

7. Galvalume

8. Epoxy primer protective layer

1) The galvanized steel sheet is hot-dipped from a zinc solution composed of 55% aluminum, 43.4% zinc and 1.6% silicon, and its processability and coating properties are basically the same as those of galvanized steel sheets. 2) The galvanized surface is anti-fingerprint coating, which protects the galvanized layer. At the same time, the anti-fingerprint coating can make the galvanized steel plate and colored sand better bonded, and the anti-fingerprint coating The color is divided into colorless transparent and light green. 3) Colored sand is the decorative layer and base protection layer of metal tiles. It is made of basalt particles with a certain particle size through high-tech coloring process and high-temperature sintering. With more than ten colors, it is resistant to ultraviolet radiation and can reduce the noise caused by rain to metal tiles. 4) Acrylic resin is the key material for bonding the steel plate and colored sand, and also serves as a protective layer on the surface of the sand to prevent the leakage of rainwater in details, which can prolong the life of the sand color

Main features of colored stone metal tiles:

Earthquake resistance - When an earthquake occurs, metal tiles will not slip off like ordinary tiles, reducing injuries.

Lightweight - light weight, reduce the load bearing of the building.

Convenience of construction - light weight, large area, simple accessories, greatly reducing construction strength and shortening construction time.

Economical—Construction on the roof of old buildings does not need to remove any roofing materials, and can be directly constructed, which minimizes the cost of waste disposal.

Colored stone metal tiles have the characteristics of weather resistance, moisture resistance, salt spray resistance, impact resistance, acid resistance, alkali resistance, heat resistance, and non-combustibility. The product is based on galvanized steel plate and is treated with multi-layer protective film. It can withstand severe cold, hail, storm, rain, snow, heat, earthquake and other harsh weather and natural disasters without cracking or aging. , Combustion in case of fire, blown by wind, has a long service life.

It can be used for wooden roof trusses, steel frames, all-steel grid frames, and concrete roofs. Due to its easy bending and cutting characteristics, it is suitable for various buildings, and it can also be safely constructed on roofs with slopes (12-90 degrees), especially suitable for "slope conversion and roof renovation" projects. At the same time, it can replace the original clay tiles, cement tiles, color steel tiles, glass fiber asphalt tiles, slate tiles, etc. During construction, it is not necessary to remove the original roof, and it can be directly constructed. Due to the large surface area and light weight of the metal tiles, they can be bent and cut, and are firmly connected and fixed by adopting unique buckle design and structure and horizontal nailing method. This kind of dry construction is simple and fast, and saves materials.

Common price calculation formula:

Conventional plate size: 2000mm*450mm Commonly used tile size: 1340mm*420mm

The number of galvanized sheets per ton of each specification = 127.38 / thickness / 0.9 * 2 / watt length;

Single color stone tile weight (kg) = 1000 / number of galvanized sheets + 0.8;

The number of colored stone tiles per ton = 1000 / weight of a single colored stone tile;

Ex-factory price of single colored stone tile including tax = price of single piece excluding tax * 1.085;

Tax-included price of a single piece of colored stone tile to Hong Kong = (price of a single piece without tax + freight / number of pieces per ton)*1.085;

Single colored stone tile FOB price = (single colored stone tile to Hong Kong tax-included price * 0.885 + port miscellaneous charges / number of colored stone tiles per ton) / exchange rate;

Single colored stone tile CFR/CIF price = single piece FOB price + sea freight / number of colored stone tiles per ton.
