What materials are generally used for color steel tiles?

Now we see that the main material of the roof and exterior wall of many factories or small houses is color steel tiles. Color steel tiles are widely used in the decoration of walls and roofs of buildings and warehouses due to their light weight and convenient construction. Let us learn about color steel tiles and its materials.

1.Definition of Color Steel Tile

Color steel tiles, also known as colored corrugated tiles, are made of colored coated steel plates that are rolled and cold-bent into various corrugated profiles. They are suitable for roofs, walls, and interior and exterior wall decoration of industrial and civil buildings, warehouses, special buildings, and large-span steel structure houses. They are light, high-strength, rich in color, easy and fast to construct, earthquake-resistant, fire-proof, rain-proof, long life, and maintenance-free. They have now been widely promoted and applied.

2.Materials of Color Steel Tiles

Color steel tiles are made of cold-rolled steel sheets and hot-dip galvanized steel sheets as the substrate. After surface degreasing, phosphating and chromate treatment, they are baked with organic coatings to form steel sheets, and then specially pressed into various forms of light panels.

It is a thin steel plate that has been double-sided sprayed and processed into various corrugations to give the thin plate good mechanical properties, and is directly laid on the roof as a roof tile. Color steel plates have good mechanical properties, large spans, convenient installation and construction, beautiful and durable appearance, light weight and high strength, good thermal insulation effect and environmental protection. In addition, it can also have different plate thicknesses and different surface coatings, which has an important impact and significance on the mechanical properties, corrosion resistance and durability of color steel plates.

Single-layer color steel tiles are generally not used for home decoration. Color steel sandwich panels are used in residential places, which have better heat insulation and sound insulation effects.

3.Basic characteristics of color steel plate

1. Light weight: 10-14 kg/m2, equivalent to 1/30 of brick wall.
2. Heat insulation: core material thermal conductivity: λ<=0.041w/mk.
3. High strength: can be used as ceiling enclosure structure plate to bear weight, bend and compressive; general houses do not need beams and columns.
4. Bright color: no surface decoration is required, the warranty period of the anti-corrosion layer of color galvanized steel plate is generally 10-15 years.
5. Flexible and fast installation: the construction period can be shortened by more than 40%.
6. Oxygen index: (OI) 32.0 (Provincial Fire Product Quality Inspection Station).
