Products Description of Colored Aluminum Coil For Roofing Panels
The aluminum roof system mainly uses 3000 series color coated aluminum coils(such us 3003,3004). The elongation, hardness, tensile strength, yield strength and other indicators of the 3000 series aluminum-manganese alloy are very suitable for the processing and painting of roof hemming, rolling equipment, and are widely used in building exterior maintenance projects such as roof/wall systems. It improves the corrosion resistance of the aluminum coil itself and makes the building appearance colorful.

Color Coated Aluminum Coil used For roofing panel system
- Roof panels: Aluminum roof panels usually roll forming by 3003/3004 color coated aluminum coil. The thickness is designed according to the purlin distance, and the perforation rate is calculated according to the project.
- Roof purlins: The material is aluminum-magnesium-manganese, which is used to support the roofing material to ensure the stability of the entire roof structure. The commonly used sizes are 40*40mm, 50*50mm, and 60*60mm. The size is selected according to the needs of the aluminum roof.
- Dustproof Layer: The dustproof layer of the aluminum roof is non-woven fabric, which is mainly used for dust and dust isolation and is laid on the upper surface of the roof base.
- Sound-absorbing cotton: The sound-absorbing cotton of the coated aluminum coil is usually made of glass wool, and its bulk density and thickness need to be determined according to calculations.
- Vapor barrier: It can be laid separately, or glass wool (with moisture-proof veneer) can be selected; the vapor barrier laid separately usually uses polyester film, high-density spunbond polyethylene film, etc.
- Roof secondary purlin: The secondary purlin material is aluminum-magnesium-manganese.
- Insulation and sound lnsulation layer: rock wool is usually used, and its thickness needs to be determined based on calculations.
- Waterproof breathable membrane: It is a high-density polyethylene non-woven fabric that blocks the invasion of wind and rain on the building structure. While strengthening the air tightness and water tightness of the building, it can also provide unique breathability, allowing the water inside the enclosure structure to be quickly discharged, effectively avoiding the formation of mold and condensation water.
- Aluminum alloy fixing seat (T-shaped code): fixed on the secondary purlin of the roof, used to fix the aluminum-magnesium-manganese alloy roof panel.
Products Advantage of Colored Aluminum coil for Roofing Panels
Color coated aluminum coils are a new type of roof panels. Coated aluminum panels are widely used in roof enclosure systems and play an important role in the development of modern artistic buildings towards comfort, lightness, durability, economy and environmental protection.
Aesthetic Pleasure
Prepainted aluminum coil can be customized according to different architectural styles and design requirements, and can perfectly blend into various environments, adding unique charm to buildings. At the same time, its streamlined appearance and modern design also make the building more modern and upscale visually.
Excellent Durability
Coated aluminum coils are usually made of aluminum alloy containing aluminum, magnesium and manganese. It not only have high strength and stability can withstand large loads and external forces without deformation or bending, but also have good weather resistance, can withstand the influence of various weather conditions, and are not easy to rust and corrode.
Easy installation
Color coated aluminum coils are simple to install compared to other materials and can be customized according to different building structures and needs. Some aluminum roof panels can be directly combined with the roof structure using an integrated design, greatly improving installation efficiency and quality.
High safety
Painted aluminum coil for roofing is light weight, strong bearing capacity and highly safe. It have good scratch resistance, impact resistance, and fire resistance, can reduce the harm caused by accidents to people.
High cost performance
Painted aluminum coils for roofing have high density, light weight, long-term durability and self-cleaning ability, low maintenance cost, which can save a lot of maintenance costs.
Environmentally Friendly
Color coated aluminum coil has good thermal insulation and heat insulation performance, which can reduce energy consumption and it is 100% recyclable and reusable, reducing environmental damage.
Aluminum Roofing panel Type
Aluminum roof panels mainly include high-edge aluminum panels (Inner height 65mm) and low-edge aluminum panels (Inner height 25mm). When choosing an aluminum roofing system for a building, not only the local climate conditions and the system's performance should be considered, but also the building's shape, style and appearance requirements. When making roofing proposals and designs, it is first necessary to understand the customer's specific requirements for the building's appearance, and then consider the building's specific performance.
High Standing Seam Aluminum Panels
Description: The common thickness of high standing seam coated aluminum panels is 0.4mm-1.2mm, the common models 65-430, 65-400, 65-420, 65-530, etc.
Advantages: High standing seam aluminum panels can not only ensure the waterproof performance of the roof panel under the condition of gentle slope, but also make the building present a rhythmic and modern appearance.
Application: For public buildings with high requirements for appearance, large area or shape span, and long service life, it is necessary to choose high-standing seam roofing system. It is commonly used in airports, railway stations, large transportation hubs, convention and exhibition centers, gymnasiums, large public entertainment facilities, public service buildings and other places.
Short Standing Seam Aluminum Panel
Description: The common thickness of short standing seam coated aluminum panel is 0.4mm-1.2mm, and the common models are 25-430, 25-400, 25-420, 25-530, etc.
Advantages: The short standing seam roof system is a supporting roof system with double-bite standing edges. The standing edge height is 25mm. The overall lightness and elegance, the local delicate and smooth, and the molding effect is very good.
Application: It is used in buildings with small roof areas, high appearance requirements and directly uses aluminum roof panels as the surface layer. It is usually used in villas and concrete foundation roofs.
Aluminum sheet Type
In order to meet the requirements of building roofs,aluminum sheet mainly have the following sheet types in building applications.
