Z-Purlins is widely used in photovoltaic support brackets. We also have a Steel z purlins factory,named Sino east steel factory,which produce z purlins for sale.
Z purlin bracket, cold formed steel refers to the finished steel with various section shapes bent by steel plate or strip steel in cold state. Cold formed section steel is a kind of economical light-weight thin-walled steel with cross-section, also known as steel cold-formed profile or cold-formed profile. Cold formed section steel is the main material for making light steel structure. It has various extremely thin, reasonable and complex sections that cannot be produced by hot rolling.
The Z-section steel of solar photovoltaic support has been developed in China in recent two years. The so-called solar photovoltaic support Z-shaped steel, as the name suggests, is a part of the products provided by the solar support factory for solar energy companies. It is a special support designed to place, install and fix solar panels.
Z purlin dimensions
As the Z-section steel of solar photovoltaic support has only developed in China in recent two years, some friends are not familiar with it and are not enough for it. The so-called solar photovoltaic support C-shaped steel, as the name suggests, is a part of the products provided by the solar support factory for solar energy companies. It is a special support designed to place, install and fix solar panels.
Z purlin sizes
There are generally two kinds of photovoltaic supports: carbon steel and aluminum alloy, while the carbon steel treated by hot galvanizing is carbon steel. The material of carbon steel is generally Q235 and Q345. The support is processed by cold bending, welding, hot galvanizing and other processes of strip steel coil. The thickness of the support is generally greater than 2mm (for some seaside, windy areas and areas, it is recommended that the thickness should not be less than 2.5mm, otherwise the connection point of sThe first step is discharging. Z-section steel is processed by hot coil cold bending, with thin wall, light weight, excellent section performance and high strength. Compared with traditional channel steel, the same strength can save 30% of materials. Generally, Z-section steel is automatically processed by Z-section steel forming machine. Z-section steel forming machine can automatically complete the forming process of Z-section steel according to the given size of Z-section steel. This involves cold rolling forming and hot rolling forming, so I won't say much here.
The second step is leveling. This needs the full assistance of the Z-beam forming machine and the supervision of the workers.
The third step is molding. At this stage, Z-section steel has a basic shape.
Then the fourth step is shaping. At this time, we can basically see the steel in the shape of "Z".
Then the fifth step is straightening. The shape alone is not enough. It has to be corrected slowly. The specification of Z-section steel must meet the national standard.

Steel channel profiles C-beam type
Galvanized C-shaped steel, hot-dip galvanized cable tray C-shaped steel, glass slot C-shaped steel, glass curtain wall C-shaped steel, cable trough C-shaped steel, reinforced C-shaped steel, double hug C-shaped steel, single-sided C-shaped steel, manual forklift C-shaped steel, C-shaped steel with unequal sides, C-shaped steel with straight edge, C-shaped steel with beveled edge, C-shaped steel with inner curling edge, C-shaped steel with inner beveled edge, C-shaped steel of roof (wall) purlin, C-shaped steel of automobile profile, C-shaped steel of expressway column, solar support C-shaped steel (21-80 series), formwork support C-shaped steel, precision C-shaped steel for equipment, etc.
shaped steel purlins are divided into five specifications of 80, 100, 120, 140, and 160 according to different heights. The length can be determined according to the engineering design, but considering the conditions of transportation and installation, the total length is generally not more than 12 meters.
Galvanized C-shaped steel has the advantages of adjustable size and high compressive strength. Although the section size of the section steel formed by cold bending is light, it is very suitable for the stress characteristics of the roof purlin, so that the mechanical performance of the steel can be fully utilized. A variety of accessories can be connected into different combinations, with beautiful appearance. The use of profiled steel purlins can reduce the weight of building roofs and reduce the amount of steel used in engineering, so it is called economical and efficient steel. It is an alternative to traditional steel such as angle steel, channel steel and steel pipe. A new building material for purlins.
Galvanized 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.
Galvanized C-shaped steel, uniform zinc layer, smooth surface, strong adhesion, high dimensional accuracy, all surfaces are wrapped by zinc layer, surface zinc content is usually 120-275g/㎡, long service life, corrosion resistance and durability
C-section steel is widely used in the steel structure of purlins and wall beams, and can also be combined into building components such as light roof trusses and supports. It can also be used for columns, beams, arms, etc. in mechanical light industry manufacturing. C-section steel is formed by cold bending of hot-rolled steel plate. It has the characteristics of thin wall, light weight, excellent section performance and high strength. Compared with traditional channel steel, the same strength can save 30% of material.
Friends will ask, there are so many advantages and uses of c-section steel. The c-shaped steel belt has good performance and saves materials. What material is this made of? Is this galvanized carbon steel? C-section steel is usually painted with color steel. So what is pre-painted steel? The surface of the steel is coated with an organic coating. Cold-rolled strip and galvanized strip (electrogalvanized and hot-dip galvanized) serve as substrates for continuous plants. After surface pretreatment (degreasing, chemical treatment), one or more liquid coatings are carried out by roll coating method, and the plate obtained by baking and cooling is a coated steel plate. Since the coating can have different colors, coated steel is often called color coated steel. Since the coating is carried out before the steel plate is formed, it is called a pre-coated steel plate abroad. Color-coated steel plate has the advantages of beautiful appearance, bright colors, high strength, good corrosion resistance, and convenient processing and forming. It also allows users to reduce costs and pollution. This enables products made of organically coated steel sheets to have excellent practicality, decoration, workability and durability. It will be a strip material for c-section steel due to its many advantages.
With the development of my country's economic construction, environmental protection and green building materials are also developing rapidly. The production technology and process of Tianjin section steel have been greatly improved, and the current development situation is relatively good. Generally used for wall beams in buildings, mainly because it has great advantages, mainly reflected in the following aspects:
1. It is very light in weight. Since it is made of hot rolled steel sheet, it has the advantage of light weight. Compared with concrete, structural planning is reduced and the construction process is relatively simple.
2. It has good flexibility, scientific and reasonable internal structure and high stability. It can usually be used to accept large oscillations, and the ability to resist natural disasters is also relatively strong.
3. Save time and effort. In the welding process, materials can be significantly saved and a certain amount of manpower and material resources can be reduced. In the process of processing, it also has the advantages of easy processing, disassembly and recycling.
Although it has advantages, it also has some disadvantages, such as delamination after hot rolling. Residual stresses can also develop if uniform cooling is not performed after machining. In general, its own advantages are enough to cover up its shortcomings.
Due to these shortcomings, C-beams have been continuously improved in production and application, and have been widely used.
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, etc.
