Physical and chemical properties:

1. Physical properties

Appearance: Color-coated tiles have rich and varied colors because they have a layer of colored coating on their surface. The coating can present various bright colors such as red, blue, green, etc., and has a certain glossiness, making the roof or wall of the building more beautiful. Its shape is usually flat, with a certain length, width and thickness, which is convenient for construction and installation.

Density: Color-coated tiles are mainly composed of substrates (usually steel plates) and coatings. The density of the steel plate part is similar to that of ordinary steel, about 7.85g/cm³, which makes the color-coated tiles have a certain weight. During the installation process, it is necessary to consider the impact of its own weight on the building structure.

Strength: It has high strength and can withstand certain external forces, such as wind, snow pressure, etc. Its strength mainly comes from the internal substrate, such as the common galvanized steel plate substrate, which can provide good tensile strength and bending strength to ensure that it will not be easily deformed or damaged under normal use conditions.

Thermal conductivity: The thermal conductivity is good because its main component, steel, is a good conductor of heat. However, in some application scenarios that require insulation, heat transfer can be reduced by adding insulation materials under the color-coated tiles.

Dimensional stability: At room temperature, the dimensions of color-coated tiles are relatively stable. However, in an environment with large temperature changes, some slight dimensional changes may occur due to the different thermal expansion coefficients of steel and coating.

2. Chemical properties

Corrosion resistance: The surface coating is the key to improving corrosion resistance. The coating can isolate the external environment from the substrate and prevent oxygen, moisture and corrosive substances (such as acid rain, salt, etc.) from corroding the substrate. For example, some high-quality polyester-coated color-coated tiles can resist corrosion for a certain period of time in outdoor environments and extend their service life.

Coating stability: The coating itself has a certain chemical stability. Different types of coatings (such as fluorocarbon coatings, polyester coatings, etc.) differ in weather resistance, chemical resistance, etc. Fluorocarbon coatings have better chemical stability and can maintain color and performance stability for a longer time under ultraviolet radiation, chemical contact, etc.

Reaction with other substances: Under normal use conditions, color-coated tiles will not react chemically with most building materials (such as wood, concrete, etc.). However, if it comes into contact with some highly corrosive chemicals (such as strong acids and alkalis), it may cause damage to the coating, thereby affecting its overall chemical stability.

Application:

Color-coated tiles are widely used in the construction field. In the construction of industrial plants, their good weather resistance and strength can effectively resist wind and rain, provide long-term roof protection for the plant, and reduce maintenance costs. In terms of civil residences, a variety of colors can meet the needs of different architectural styles, and the use of roofs can add beauty and uniqueness. In agricultural facilities, such as farm sheds and agricultural product warehouse roofs, color-coated tiles can withstand harsh environments and ensure the stability of the internal environment. Whether it is urban buildings or rural facilities, color-coated tiles have become an ideal choice of building materials because of their practical and decorative characteristics.
