Products Description
Aluminum roofing panels are made of high-strength aluminum-magnesium alloy materials, and the surface is specially treated to have good weather resistance and corrosion resistance, which can ensure a long service life. Compared with traditional roofing materials, aluminum-magnesium-manganese roof panels have the characteristics of light weight, high strength, and beautiful appearance. They can effectively reduce the weight of buildings and improve the safety of buildings.
Alloy composition introduction
3003/3004 aluminum alloy (AlMg1Mn1) is widely recognized as the key material for roofs and exterior walls with a design service life of more than 50 years due to its moderate structural strength, weather resistance, resistance to processing, and easy bending and welding. In response to the design of marine climate buildings, 5052 ship-grade aluminum alloy materials with stronger corrosion resistance can be selected.
Mechanical properties
Aluminum roof panels are usually made of aluminum alloy AA3004 aluminum-magnesium-manganese alloy press molding, and the alloy state is H36/H46. Its yield strength is ≥190 MPa, the tensile strength is 240~285 MPa, and the elongation is ≥3%.

Products Advantage
Lightweight: The density of aluminum is 2.73g/cm3, only 1/3 of that of steel.
High strength: It can be achieved through component configuration, processing and heat treatment methods.
Corrosion resistance: It has self-rust prevention ability, and the oxide layer formed can prevent metal oxidation and rust, and has good acid and alkali resistance.
Aesthetic Pleasing: It can be anodized, electrophoresed, chemically treated, polished, and painted.
Good electrical conductivity: Non-magnetic and low spark sensitivity, can prevent electromagnetic interference and reduce flammability in special environments
Easy to install: Aluminum metal can be connected in many ways, such as riveting, welding, gluing, etc.
Product type
Color coated aluminum roof panels are usually two types: unpainted panels and painted panels
Non-painted Aluminum Roofing panels
Non-painted aluminum roof panels: Common non-painted roof panels include Stucco Aluminum panels and Emboss Aluminum panels.
Smooth aluminum alloy is the basic state of aluminum alloy sheets, and the surface of the sheet is treated to form a hammered surface, which can effectively reduce light pollution, appropriately adjust the mechanical properties of the material, and increase the cost-effectiveness of the material.
Painted Aluminum Roofing Panels
According to the coating process, It can be divided into: spray sheets and pre-roller coated sheets;
According to the type of paint, It can be divided into: PE, PVDF, HDP etc. PVDF pain has the best anti-aging performance.
Aluminum Roofing panel type
In order to meet the requirements of building roofs, aluminum-magnesium-manganese alloy roof panels mainly have the following sheet types in building applications.
Straight panels
Introduction：The rib height of the straight sheet type is generally 65 mm, and the commonly used sheet widths are 300 mm, 400 mm and 500 mm. The sheet width of 300 mm is used when the roof load is large; 400 mm is commonly used and economical; 500 mm is the most economical plate type for the roof panel itself, but the spacing between the lower purlins is small, and appropriate measures must be taken to prevent the sheet from deforming.
Application：Applicable to single-slope, double-slope and single-curved roofs with the radius larger than the natural arc radius.
Curved panels
Introduction: The curved panels includes positive curved plate and reverse curved plate.
Application: Applicable to single-curved roofs with a radius smaller than the natural arc radius
Sector panels
Introduction: Sector panels include straight sector panels, positive sector panels, and reverse sector panels.
Application: Applied to double curved roof
How to choose Aluminum Roofing panels?
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 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 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.
