The selection of solar bracket materials and installation methods requires strict calculations to determine. In addition, weather resistance is also one of the selection criteria affected by the texture, climate, environment and other factors of the installation site. For example, the installation site with soft texture can be fixed by ground anchors. If the historical maximum wind speed or maximum snow volume is within a certain range, you can appropriately select materials that can meet the requirements and have low costs. TIn addition, factors such as maintenance and material recycling need to be considered.

At present, the materials of solar brackets mainly include Zn-Al-Mg photovoltaic bracket, aluminum alloy, stainless steel, galvanized steel, etc. 

1. The Zinc-Aluminum-Magnesium (ZAM) photovoltaic (PV) bracket

is an innovative mounting system designed for solar panel installations. It is recognized as a superior option compared to traditional galvanized steel brackets due to its high corrosion resistance and superior strength-to-weight ratio.The ZAM photovoltaic bracket is ideal for use in various settings, including residential, commercial, and industrial applications. Its durability and strength make it well-suited for areas with severe weather conditions or high potential for corrosion, such as coastal regions and areas with high levels of pollution.

2. Aluminum alloy bracket

is generally used in solar applications on the roofs of civil buildings. Aluminum alloy has the characteristics of corrosion resistance, light weight, beautiful and durable, but its bearing capacity is low and cannot be used in large-scale solar power station projects. In addition, the price of aluminum alloy is slightly higher than that of hot-dip galvanized steel.

3. Galvanized steel bracket

has stable performance, mature manufacturing technology, high bearing capacity, and easy installation. They are widely used in civil and industrial solar photovoltaic and solar power stations. Among them, the steel sections are all produced in factories with uniform specifications, stable performance, excellent anti-corrosion performance, and beautiful appearance. It is worth mentioning that the combined steel bracket system only needs to use specially designed connectors to assemble the channel steel for on-site installation. The construction speed is fast and no welding is required, thus ensuring the integrity of the anti-corrosion layer. The disadvantage of this product is that the connector process is complicated, there are many types, and it has high requirements for production, manufacturing, and design, so it is expensive. Another disadvantage of galvanized steel is that the final recycling value of the material is not as high as the first two.

At present, the most commonly used is galvanized steel bracket, which mainly uses steel as the main material. The so-called steel section is a strip steel with a certain cross-sectional shape and size. Its main types are I-beams, channel steels, angle steels, round steels, square steels, C-shaped steels, H-shaped steels, etc.

1. Angle steels

can be composed of various load-bearing components according to different structural needs, and can also be used as connectors between components. Widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves. Angle steel is a carbon structural steel for construction. It is a simple cross-section steel, mainly used for metal components and factory frames. It requires good weldability, plastic deformation performance and certain mechanical strength during use. The raw material billet for producing angle steel is low-carbon square billet, and the finished angle steel is delivered in hot-rolled, normalized or hot-rolled state.

2. H-shaped steel

is an economical and efficient profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". Since all parts of H-shaped steel are arranged at right angles, H-shaped steel has the advantages of strong bending resistance, simple construction, cost saving and light structure weight in all directions, and has been widely used.

H-shaped steel is divided into wide flange H-shaped steel (HW), middle flange H-shaped steel (HM), narrow flange H-shaped steel (HN), thin-walled H-shaped steel (HT), H-shaped steel pile (HU), etc.

3. C-shaped steel

is made by hot rolling and cold bending. It has thin walls, light weight, excellent cross-sectional performance, and high strength. Compared with traditional channel steel, it can save 30% of materials with the same strength.

C-shaped steel is widely used in purlins and wall beams of steel structure buildings, and can also be combined into lightweight roof trusses, brackets and other building components. In addition, it can also be used for columns, beams and arms in mechanical light industry manufacturing.

4. Rectangular tube

is a hollow long steel strip, which is widely used as a pipeline for conveying fluids, such as oil, natural gas, water, coal gas, steam, etc. In addition, when the high bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used to produce various conventional weapons, gun barrels, shells, etc. It is mainly used as a beam in photovoltaic bracket systems.
