Colored corrugated roofing sheets are lightweight roofing materials with a metal base and a coated surface that creates a corrugated pattern. While common metals on the market include aluminum and steel, we recommend colored corrugated aluminum roofing sheets for their lightweight, high strength, corrosion resistance, and aesthetic appeal. Thickness generally ranges from 0.6-1.5mm, and specifications vary between manufacturers. Custom specifications can also be customized to meet customer needs.
Material and Alloy Composition of Color Corrugated Roofing Sheets:
Common materials include 1060 and 3003 aluminum. 1060 is pure aluminum with an aluminum content of over 99.5%, offering excellent ductility and corrosion resistance. 3003 is an aluminum-manganese alloy with excellent hardness and rust resistance, making it a common material for colored coated aluminum roofing sheets.
Surface Treatment of Colored Corrugated Roofing Sheets:
– Fluorocarbon Spray Coating:
Offers excellent weather resistance, corrosion resistance, and stain resistance, withstands extreme weather conditions, resists fading, and maintains color, making it suitable for construction projects requiring high durability.
– Polyester coating:
Relatively low cost, with excellent weather resistance and decorative properties, meeting the appearance and protection requirements of general buildings.
– Other treatments:
Surface treatments such as roller coating, powder coating, wood grain transfer printing, and oxidation plating can be used to achieve various decorative effects, such as simulated wood grain and stone grain, to meet personalized design needs.
Performance Advantages of Coloured Corrugated Roofing Sheets:
– Waterproof:
A waterproof layer is generally not required for roofs with pitches of 15-90 degrees. Its corrugated structure effectively guides rainwater flow. Construction methods such as overlap, undercut, or buckling also enhance waterproofing, preventing rainwater seepage.
– Wind and earthquake resistance:
It can withstand winds up to force 12 and provides reliable decorative effects on 90-degree building facades. Its lightweight and flexible material makes it resistant to shattering during earthquakes, providing excellent seismic performance.
– Thermal Insulation:
The core of corrugated aluminum roofing sheet is water-corrugated, creating air channels between the front and back panels, providing thermal insulation and making it an ideal product.
– Soundproofing and Noise Reduction:
Some colored corrugated aluminum roofing sheets utilize a porous foam core or special structural designs, offering excellent sound absorption properties and effectively reducing the impact of external noise on the indoor environment.
– Fireproofing:
Aluminum alloy is a non-combustible material, generally rated A2, offering excellent fire resistance and ensuring building safety.
Applications of Color Corrugated Roofing Sheets:
– Industrial Buildings:
Widely used for roofs and walls of new factory buildings, particularly those exposed to corrosive gases and moisture, such as refineries, power plants, and chemical plants. Its strong corrosion resistance effectively protects against the erosion of industrial environments.
– Civil Buildings:
Commonly used for sloped roofs of villas, self-built homes, and vacation homes, as well as sunshades and simple houses. Its aesthetically pleasing and versatile design enhances the overall quality and appearance of a building.
– Public Buildings:
Widely used in public buildings such as high-speed rail stations, airport terminals, large stadiums, shopping malls, and schools, it can meet the needs of large-span roofs while showcasing the beauty and grandeur of modern architecture.
Colored corrugated roofing sheets are often used on the roofs of industrial plants, commercial buildings, warehouses, garages and other places. Due to their superior performance and beautiful appearance, they are increasingly favored by the construction industry.
