Color Coated Corrugated Steel Sheet is a popular and widely used building material known for its attractive appearance, durability, and versatility. It is made from cold-rolled steel sheets that are coated with a protective layer of paint or other colored coatings. The corrugated profile of the sheet provides additional strength and rigidity, making it suitable for various applications in construction, roofing, and cladding.
The introduction of Color Coated Corrugated Steel Sheet offers several advantages:
1. Aesthetics: The wide range of color options allows for creative and eye-catching designs, making it an excellent choice for architectural and decorative applications.
2. Corrosion Resistance:
The coating on the steel sheet acts as a barrier against moisture and atmospheric elements, enhancing the sheet's resistance to corrosion.
3. Durability:
The corrugated profile adds strength and rigidity to the sheet, making it resistant to impacts, bending, and other mechanical stresses.
4. Lightweight:
Color Coated Corrugated Steel Sheets are relatively lightweight, reducing the structural load and making them easier to handle and install.
5. Weather Resistance:
The color coating protects the steel from fading, chalking, and weathering due to exposure to UV radiation and harsh weather conditions.
6. Thermal Efficiency:
The reflective properties of some color coatings help in reducing heat absorption, contributing to better thermal insulation.
7. Cost-Effective:
Compared to other roofing and cladding materials, Color Coated Corrugated Steel Sheets are relatively affordable, making them a cost-effective choice for various projects.
Applications of Color Coated Corrugated Steel Sheet include:
Roofing:
It is commonly used for residential, commercial, and industrial roofing applications.
Wall Cladding:
It is used as exterior wall cladding for buildings, providing both aesthetics and protection.
Fencing:
It is utilized for fencing and boundary walls due to its strength and durability.
Agricultural Buildings: It finds applications in agricultural sheds, barns, and warehouses.
Industrial Shelters:
It is used for construction site shelters and temporary buildings.
The versatility, durability, and aesthetic appeal of Color Coated Corrugated Steel Sheet have made it a popular choice for various construction and architectural projects worldwide.
In China, the standards for Color Coated Corrugated Steel Sheet are set and regulated by the Chinese National Standards (GB/T) issued by the Standardization Administration of China (SAC). The relevant GB/T standard for Color Coated Corrugated Steel Sheet is:
GB/T 12754-2019: Prepainted corrugated steel sheets. This standard applies to color-coated steel plates and steel strips used inside and outside buildings.
GB/T 12754-2019 specifies the requirements for prepainted corrugated steel sheets, which include color-coated corrugated steel sheets. The standard covers the mechanical properties, coating weight, thickness, and other performance characteristics of the organic coating used for color-coated steel sheets.
This GB/T standard ensures that Color Coated Corrugated Steel Sheet products produced and used in China meet the necessary quality and safety requirements for their intended applications.
In the United States, the standards for Color Coated Corrugated Steel Sheet are primarily set and maintained by the American Society for Testing and Materials (ASTM). However, it's important to note that there isn't a specific ASTM standard dedicated solely to color-coated corrugated steel sheets. Instead, the relevant standards are typically related to the base material (steel sheet) and the coating used for color coating.
For the base steel sheet, the most commonly referenced ASTM standard is:
ASTM A653/A653M: Standard Specification for Steel Sheet, Zinc-Coated (Galvanized) or Zinc-Iron Alloy-Coated (Galvannealed) by the Hot-Dip Process.
ASTM A653/A653M covers the requirements for steel sheet products that are zinc-coated or zinc-iron alloy-coated by the hot-dip process. This specification includes the base material used for color-coated corrugated steel sheets.
For the color coating, ASTM standards for organic coatings on metal substrates, such as steel, are relevant. These standards include:
ASTM D2244: Standard Practice for Calculation of Color Tolerances and Color Differences from Instrumentally Measured Color Coordinates.
ASTM D3363: Standard Test Method for Film Hardness by Pencil Test.
ASTM D4214: Standard Test Methods for Evaluating the Degree of Chalking of Exterior Paint Films.
In the United Kingdom, the standards for Color Coated Corrugated Steel Sheet are generally aligned with the European standards set by the European Committee for Standardization (CEN). The most relevant European standard for Color Coated Corrugated Steel Sheet is:
EN 10169: Continuously organic coated (coil coated) steel flat products - Technical delivery conditions.
EN 10169 specifies the requirements for continuously organic-coated (coil-coated) steel flat products, which include color-coated corrugated steel sheets. The standard covers the characteristics of the organic coating, such as thickness, adhesion, flexibility, and appearance.
EN 10169 ensures that Color Coated Corrugated Steel Sheet products produced and used in the UK meet the necessary quality and safety requirements for their intended applications.
In Japan, the standards for Color Coated Corrugated Steel Sheet are primarily set and regulated by the Japanese Industrial Standards (JIS). The relevant JIS standard for Color Coated Corrugated Steel Sheet is:
JIS G 3312: Prepainted hot-dip zinc-coated steel sheets and coils.
JIS G 3312 specifies the requirements for prepainted hot-dip zinc-coated steel sheets and coils, which include color-coated corrugated steel sheets. The standard covers the mechanical properties, coating weight, thickness, and other performance characteristics of the organic coating used for color-coated steel sheets.
