Aluminum alloy used for roofing and wall systems.

The curtain wall and roofing systems mainly use 3000 series aluminum-manganese (aluminum-manganese-magnesium) alloys, while 5000 series aluminum-magnesium alloys are gradually being applied to curtain wall panels. Based on different processing methods, the elongation, hardness, tensile strength, and yield strength of 3000 series aluminum-manganese alloys are very suitable for the processing of roofing edge rolling and pressing equipment, thus widely used in roofing, wall systems, and other building exterior maintenance projects, and combined with various painting systems and coating processes, making the building appearance rich and colorful, while also enhancing the corrosion resistance of the aluminum alloy itself.

The main aluminum alloy used in building covering systems is the 3000 series 'aluminum-magnesium-manganese alloy', among which alloys 3003, 3004, 3005, 3103, and 3105 are widely used. This is because the manganese content in aluminum-magnesium-manganese alloys stabilizes near its saturation point, and under the joint action of other metals, the 3000 series aluminum alloys have appropriate elongation, good corrosion resistance, good processing performance, and can be smelted and processed into alloys of different hardness according to different application requirements.

Classification of aluminum plates.

Aluminum alloy plates can be divided into non-painted products and painted applications, classified as follows:

a. Non-painted products: Stucco hammered aluminum plates (irregular patterns), embossed plates (regular patterns); anodized pre-passivated aluminum surface treatment plates. These products do not undergo painting treatment on the surface, have low appearance requirements, and are also relatively inexpensive.

b. Painted products:

Divided by coating process: spray-coated panel products (Spray coat) and pre-rolled coated panels (Coilcoat);

Divided by paint type: polyester (Polyester), polyurethane (Polyurethane), polyamide (Polyamide), modified silicone (Modified Silicone), epoxy resin (Epoxy), fluorocarbon (PVDF), etc.

These products require surface cleaning treatment of aluminum alloy plates, followed by the application of colorless or colored primer and topcoat on the aluminum plate surface, which is then cured at high temperatures (two coats one bake, three coats two bakes, three coats three bakes), resulting in plates with various colors. Among the various coatings available for building aluminum alloy materials, the main performance difference is the resistance to ultraviolet rays from sunlight. All the above painting systems are coatings formed by mixing organic plastics, solvents, color masterbatches, etc., according to formulas, which gradually age under sunlight and various climatic conditions, manifesting as gradual fading, powdering, cracking, peeling, etc. The most commonly used coating on the front side is fluorocarbon paint (PVDF), which currently has strong resistance to ultraviolet rays; the back side can choose polyester or epoxy resin coatings as protective paint or left untreated. Additionally, a removable protective film can be applied to the front side.

Vertical lock edge 65-320-400-420-500 introduces advanced international design concepts, with materials generally selected from aluminum-magnesium-manganese alloys. Its specific gravity is 1/3 of that of color steel, but its service life can reach more than three times that of color steel. Due to the soft and malleable panel type, roofing panels use aluminum-magnesium-manganese alloys of grades 3003/3004; this greatly meets design requirements, thus this system is widely used in buildings such as airports, sports venues, theaters, etc. According to customer needs, other specifications can be selected: vertical single lock 65-320-400-420-500; vertical double lock 25-430-530.

The superior performance of aluminum, magnesium, and manganese materials.

 

　

◆ Tensile strength of 265MPa is 2.5 times that of ordinary aluminum plates;

 

◆ Corrosion resistance: 3 times that of ordinary aluminum plates, 2 times that of stainless steel;

◆ Noise reduction and shock absorption, able to withstand large impact loads;

◆ Excellent electromagnetic wave shielding performance protects the human brain from harm;

◆ An ideal environmentally friendly material that does not release harmful toxins;

Advantages of aluminum-magnesium-manganese roofing systems:

1. No joints, no screw holes, the building appearance is intact.

2. Can be bent into inner and outer arcs.

3. Different materials and colors can be selected.

4. Overall structural waterproofing and drainage functions.

5. Can be used for roofs with slopes as low as 1.5°.

4;整体结构性防水、排水功能

5;可用于坡度小至1.5°的屋面

6; Excellent wind pressure resistance (in conjunction with the base plate), especially suitable for areas with frequent typhoons and storms.

7; Can eliminate pressure caused by thermal expansion and contraction.

8; Simple and quick machine rolling, convenient and economical for construction.

9; Facilitates the laying of thermal insulation and sound-absorbing layers.

10; No need for chemical seam adhesives, eliminating pollution and aging issues.

11; Roof requires no maintenance and can be produced on-site.

 

 

YX65-320-400-420-500 standing seam roof panels are usually made of AA3004 aluminum-magnesium-manganese alloy.

2) Material hardness is formed by rolling aluminum-magnesium-manganese alloy plates of grade 4 or 6.

3) The standard thickness of aluminum-magnesium-manganese alloy plates is 0.7mm to 1.2mm, with 0.9mm typically selected under normal circumstances.

4) Surface treatment: Before leaving the factory, the aluminum-magnesium-manganese alloy coils undergo a pre-roller coating treatment with fluorocarbon paint. After two coatings and two baking processes, the paint film thickness can be guaranteed to be above 22-25um. The color of the paint can be adjusted according to design needs.

b) Original color hammer pattern.

Before leaving the factory, the aluminum-magnesium-manganese alloy coils are treated with a hammer pattern process, creating a texture similar to orange peel on the surface of the alloy.

5) Applicable projects:

a) Urban public buildings:

Airport terminals and hangars, train station buildings and platform canopies, gymnasiums, and other constructions.

b) Urban residential buildings:

Community parks, decorative roofs for residential houses and villas, and other constructions.

c) Large-span steel structure enclosure systems:

Logistics centers, factories, and other constructions.
