Solar photovoltaic bracket is a special bracket designed for placing, installing, and fixing solar panels in a solar photovoltaic power generation system. General materials include aluminum alloy, carbon steel, and stainless steel.Products related to solar energy support systems are made of carbon steel and stainless steel. The surface of carbon steel is hot-dip galvanized and will not rust after 30 years of outdoor use. The solar photovoltaic support system is characterized by no welding, no drilling, 100% adjustable, and 100% reusable.

The global energy crisis has promoted the rapid development of the new energy industry, and solar energy is the most i z purlin vs c purlin

mportant basic energy among various renewable energies; Therefore, as a solar power generation technology that converts solar radiation into electricity, the photovoltaic industry is developing rapidly; In the old concept, the photovoltaic industry mainly included the production chain of solar modules, and the production chain of electrical control components such as controllers and inverters.Solar photovoltaic systemThe application advantages of solar support systems in solar panel support go far beyond simple production and installation. Solar panels can also be flexibly moved according to the sun's rays and seasons. Just like when it was first installed, the slope of each solar panel can be adjusted to accommodate different angles of light by moving fasteners, and the solar panel can be accurately fixed in a specified position by retightening.

In fact, the manufacturing process of the finished stent is not simple, and high-quality products often have multiple technical patents. The following is an example of an assembled steel bracket.First, high-quality steel sections typically have a high level of galvanizing process. According to the requirements of national standards, the average thickness of zinc coating should be greater than 50 μ m. Minimum thickness greater than 45 μ m。 In fact, although the average thickness of the zinc coating on many products can meet the requirements, the minimum thickness is less than 40 μ m. Pitting often occurs in practical use. Halogens corrode steel at a very rapid rate, which can weaken the overall support structure within a year, causing potential safety hazards. Therefore, achieving a highly uniform galvanizing process is not easy.Secondly, the connection of section steel and steel is a technical difficulty. A complete set of effective connection methods, including not only clever ideas on the connection, but also matching the design of channel steel back holes, occluding teeth, and so on. This involves various aspects of iron and steel metallurgy technology such as stamping and casting.In addition, double-sided channel steels used to withstand large loads must be welded back to back. There is a significant gap between the levels of various welding processes. Pressure laser welding can ensure uniform connection of the entire section, and the two channel steels are fully integrated to bear the force together; The electric welding technology can only fix the two channel steel parts together, and the stress form is closer to the laminated beam. In order to improve the bearing capacity of some section steels, the cold rolling of stiffening ribs is also added to the channel steel.

Galvanized c purlin brackets or cee purlin brackets are very important in solar project.

The C-shaped steel produced by C-shaped steel enterprises is flat and square, and can be directly cold rolled or cut using wide steel chains. Channel steel is a kind of strip steel with a certain cross-section shape and specifications, which is one of the four types of steel. Channel steels are divided into simple section channel steels and complex section channel steels according to their cross-sectional shapes. Cold formed steel is a finished steel with various cross sectional shapes formed by bending steel plates or strips under cold conditions. Cold formed steel is a kind of economical section light thick wall steel, also known as steel cold formed profiles or cold formed profiles. The C-shaped steel is automatically processed by a C-shaped steel forming machine. The forming process of CC shaped steel can be automatically executed according to the given C shaped steel specifications. C-shaped steel is divided by thickness, with a thickness of 4mm for thin C-shaped steel (ultra thin: 0.2mm), 4 ー 60mm for thick C-shaped steel, and 60 ー 115mm for extra thick C-shaped steel. According to cold rolling, C-shaped steel is divided into hot rolling and cold rolling.

The overall width of the slab is 500 ー 1500mm, and the thin thickness is 600 ー 3000mm. According to the type of steel, there are ordinary steel, high-quality steel, carbon steel, spring steel, stainless steel, tool steel, heat resistant steel, bearing steel, silicon steel, industrial pure iron plate, etc. There are oil barrel plate, pond porcelain plate, bulletproof plate, surface coating, galvanized plate, tinplate, lead plate, plastic composite C steel, etc.

Thick C-shaped steel is basically the same as thin C-shaped steel. In various fields of commodities, in addition to bridge C-sections, boiler C-sections, automotive industry C-sections, high-pressure vessel C-sections, and dual pressure vessel C-sections, there are also some C-sections, such as automotive girder C-sections (2). 5~10mm thick), line C-sections (2). 5~8mm thick), stainless steel C-sections, and heat resistant C-sections, which are all thick plates.

In addition, the C-shaped steel material also indicates that not all C-shaped steels are the same, and the application of C-shaped steels varies depending on the material.

It is C shaped steel beam that has the advantages of adjustable size, high compressive strength and so on. Through the cold forming of the steel, although its section size is light and light, but very in line with the roof purlin stress characteristics, so that the mechanical efficiency of steel get light play. A variety of accessories can be connected into different combination, beautiful appearance, the use of steel purlin, can reduce the building roof weight, reduce the amount of engineering steel, so known as economic and efficient steel, is the replacement of Angle steel, channel steel, steel pipe and other traditional steel purlin of new building materials.


The main advantages of galvanized c purlin bracket are:

1. Durable: in urban or offshore areas, the standard hot-dip galvanized rust prevention layer can be used for 20 years; It lasts longer in the suburbs, more than 50 years.

2, comprehensive protection: each part can be plated with zinc, comprehensive protection.

3, the coating toughness is strong: can withstand mechanical damage in transport and use.

4, good reliability.

5, save time and effort: galvanizing process is faster than other coating construction method, and can avoid the time required for painting on the site after installation.

6, the cost is low: galvanized is more expensive than spray painting, but in the long term, the cost of galvanized is low, because of the durability of galvanized.

Scope of application

Galvanized cee purlin brackets are widely used in steel structure building purlins, wall beams, can also be combined into lightweight roof truss, bracket and other building components. In addition, it can also be used for column, beam and arm in mechanical light industry manufacturing.

Outstanding feature

Galvanized cee purlin brackets zinc layer uniform, smooth surface, strong adhesion, high dimensional accuracy, all the surface is covered by zinc layer, surface zinc content is usually in 120-275g/㎡, long service life corrosion resistance durable, is the strongest protective force of a galvanized C type steel high quality.

Preparation of galvanized cee purlin brackets

Galvanized C shaped steel is automatically machined by C shaped steel forming machine. C shaped steel molding machine can automatically complete the c shaped steel beam according to the given size.
