Product Description
1. Structural features:
- Low rib height: The rib height of the low standing edge roof panel is usually 25mm, which is lower than that of the high standing edge roof panel (the rib height is generally 65mm). This lower rib height design makes the roof panel look more concise, light, and smooth in appearance, which can bring a unique visual effect to the building and is suitable for modern minimalist architectural design.
- Various board types: including straight board, positive arc board, reverse arc board, fan board and fan arc board. Straight board is suitable for single slope, double slope and single curved roof with a radius greater than the natural arc radius; positive and reverse arc boards are suitable for single curved roof with a radius less than the natural arc radius; fan board and fan arc board are suitable for double curved roof.
- Locking edge form: divided into single locking edge and double locking edge. Single locking edge is 270° curling edge, and double locking edge is 360° locking edge. Generally speaking, when the roof slope is less than 25°, double locking edge is required to ensure the waterproof performance of the roof; when the slope is greater than 25°, single locking edge can be selected.
Performance advantages:
- Good durability: The aluminum-magnesium-manganese alloy material itself has good corrosion resistance. By reacting with the air to form an oxide layer, it can effectively protect the material, maintain stable performance under various climatic conditions, and have a long service life.
- Lightweight: The weight of the aluminum-magnesium-manganese roof panel is relatively light, about one-third of the weight of the color steel plate, which makes it more convenient during construction and transportation, and also reduces the overall load of the building.
- Moderate strength: The magnesium, manganese and other elements in the raw materials give it a certain strength, which can meet the bearing requirements of the roof.
- Good waterproof performance: The low standing edge roof panel is a double-edged fully supported roof system, which does not require the assistance of other waterproof filling materials. The roof panel ribs are folded and sealed with electric locks. The folded roof is completely waterproof and waterproof.
- Diverse surface treatment: A variety of industrial treatments can be performed to make the appearance of the roof panel more beautiful and meet the design requirements of different buildings.
- Good processing performance: easy to perform bending, roll bending and other processing operations, and can adapt to various complex roof shapes and design requirements.
Application:
This kind of sheet widely used in villas, homestays, commercial blocks, hotels, clubs and other buildings, as well as some small buildings with high requirements for building appearance and low requirements for roof load.
However, the load capacity and wind resistance of low-rise roof panels are relatively weak. In some large buildings or windy areas with high requirements for roof structure strength and wind resistance, they may need to be used with caution. In actual applications, the appropriate type of roof panel should be selected based on the specific building needs and use environment.

Frequently Asked Questions
What are the primary materials used in these low standing edge roof sheets?
These roof sheets are manufactured using high-quality 3003 and 3004 aluminum-magnesium-manganese alloys, which naturally form a protective oxide layer when exposed to air.
What is the difference between single locking edge and double locking edge?
A single locking edge is a 270° curling edge, suitable for roof slopes greater than 25°. A double locking edge is a 360° locking edge, which is required for slopes less than 25° to ensure optimal waterproof performance.
How long is the service life of these aluminum alloy roof sheets?
Thanks to their superior corrosion resistance and fluorocarbon paint finish, these roof panels offer a long service life of 50+ years.
Do these roof sheets require additional waterproof filling materials?
No, the low standing edge roof panel is a double-edged fully supported system. The ribs are folded and sealed with electric locks, making the roof completely waterproof without extra sealants.
What are the main applications and limitations of low standing edge roof panels?
They are widely used in villas, homestays, commercial blocks, hotels, and clubs. However, because their load capacity and wind resistance are relatively weak, they should be used with caution in areas with high wind loads or heavy structural demands.
