Advanced technology: Each node of the disc-type connection has 8 directions of connection, which is an upgraded product of the scaffolding currently used in China. Raw material upgrade: The main materials are all made of vanadium-manganese alloy structural steel, which is 1.5-2 times stronger than the plain carbon steel pipe (national standard Q235) of traditional scaffolding. Hot-dip galvanizing process: The main components are treated with internal and external hot forging zinc anti-corrosion process, which not only improves the service life of the product, but also provides further guarantee for product safety, while also being beautiful and beautiful. Large bearing capacity: Taking the heavy-duty support frame as an example, a single vertical pole (060) allows a load of up to 140KN. Low dosage and light weight: Under normal circumstances, the spacing between the vertical poles is 1.2 meters, 1.8 meters, 2.4 meters, and 3.0 meters. The step distance of the horizontal bar is 1.5 meters. The maximum spacing can reach 3 meters, and the step distance reaches 2 meters. Therefore, the dosage under the same support area will be reduced by 60%-70% compared with the traditional bowl-type support frame. Fast assembly, easy use, cost saving: Due to the small amount and light weight, operators can assemble more conveniently, and the efficiency can be increased by more than 3 times. Each person can set up 200-300 cubic meters of frames per day. The comprehensive costs (labor costs for erection and dismantling, round-trip transportation costs, material rental costs, machine shift costs, material loss, loss costs, maintenance costs, etc.) will be saved accordingly, generally more than 30% can be saved.

Sanbo highway guardrail is the best type of guardrail in terms of protection. Currently, the main styles of Sanbo highway guardrail are Japanese and American. The Japanese Sanbo guardrail has a complex production process, while the American Sanbo guardrail has high raw material toughness, low consumables, and relatively low production costs. The following is a brief introduction to the types and specifications of Sanbo highway guardrails. Core components of Sanbo Expressway guardrail Sanbo Expressway guardrail column: According to the national standard requirements for Sanbo Expressway guardrails in my country, the column length is 1.85 meters and the column depth is 1.1 meters; the column cross-sectional diameter is 140mm, the tube wall thickness is 4.5mm, and hot-dip galvanizing or hot-dip galvanizing + plastic dipping anti-corrosion treatment is adopted. Sanbo Expressway guardrail block: The block is an important energy-absorbing component of the guardrail parts, which adopts a hexagonal hollow design. The hollow allows the column and the guardrail to be perfectly seamlessly spliced. The installation of Sanbo Expressway guardrail columns, block, and guardrail is crucial. The effect test can be carried out after the three are installed. Once an error occurs in a certain link, the overall protective effect of the guardrail may be affected. The connection between the three is mainly through the special bolts for the guardrail, and this bolt adopts a good anti-theft device to prevent theft by criminals. Many friends consider the complexity of replacing the guardrail. In fact, the use of special equipment and tools can easily and freely replace the guardrail and the barrier block. Specifications of three-wave high-speed guardrail The Ministry of Transportation's industry standard "Highway Corrugated Beam Steel Guardrail" stipulates that the total length of the standard guardrail is 4320 mm (4 meters left after installation) and the column spacing is 4 meters.

The thickness of hot-dip galvanizing is an important quality and technical indicator of photovoltaic brackets, which is related to the safety and durability of the structure. Although there are national and industry standards, the thickness of the galvanized layer of the bracket does not meet the standards, which is still a common technical problem of the bracket. The hot-dip galvanizing process is a relatively stable and reliable steel surface treatment solution to resist environmental corrosion. There are many factors that affect hot-dip galvanizing, such as: steel substrate composition, surface state (such as roughness), substrate internal stress, geometric dimensions, etc. Among them, the thickness of the substrate has a greater impact on the thickness of the hot-dip galvanizing. Generally, the thicker the plate, the thicker the hot-dip galvanizing thickness.

1. Hot-dip galvanized steel pipe structure: Hot-dip galvanized pipe is to make molten metal react with iron matrix to produce alloy layer, so that the matrix and coating are combined. Hot-dip galvanized pipe is to pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to the hot-dip plating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The hot-dip galvanized steel pipe matrix undergoes complex physical and chemical reactions with the molten plating solution to form a corrosion-resistant zinc-iron alloy layer with a tight structure. The alloy layer is integrated with the pure zinc layer and the steel pipe matrix. Therefore, it has strong corrosion resistance. 2. Galvanized strip pipe structure: Galvanized strip pipe adjusts the production process of hot-dip galvanized pipe. First, the strip steel used for pipe making is pickled. In order to remove the iron oxide on the surface of the strip steel, after pickling, it is cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to the hot-dip plating tank. Then air-dry and make into pipes. It has uniform and bright coating, very little galvanizing, and is cheaper than hot-dip galvanized pipes. Its corrosion resistance is slightly worse than hot-dip galvanized pipes!

The production implementation standard of the ring lock scaffolding (JG/T 503-2016) clearly stipulates that the ring lock scaffolding components must be treated with hot-dip galvanizing. Why is this? As we all know, there are two types of ring lock scaffolding: black rods and galvanized rods. The hot-dip galvanizing treatment technology is used to extend its service life. The scaffolding treated with hot-dip galvanizing has good anti-corrosion performance, making the surface texture of the material uniform, anti-corrosion and wear-resistant, and more beautiful in appearance. The service life of hot-dip galvanized ring lock scaffolding is much higher than that of the ring lock scaffolding. Bolt connections are abandoned, and the disc-type rods are all electrochemically protected by hot-dip galvanizing through the principle of zinc anti-atmospheric corrosion to steel and other materials. The zinc carbonate protective film on the surface can slow down the corrosion rate of zinc. Even if it is damaged, it will form a zinc film layer again. It can generally be used for more than 10 years.

Highway corrugated guardrails are used outdoors all year round, which requires the guardrails to have the characteristics of corrosion resistance, weather resistance, acid resistance, etc. There are generally three types of anti-corrosion treatment for corrugated guardrails. 1. Hot-dip galvanizing Hot-dip galvanizing is to immerse the rusted metal material into a zinc liquid of about 500 degrees to attach a new layer to the metal surface to achieve the purpose of anti-corrosion. The hot-dip galvanizing process has a history of more than 100 years. The technology is relatively mature. Most highway guardrails are treated with this process. 2. Powder spraying Powder spraying is to use electrostatic powder spraying equipment to spray powder onto the degreased workpiece. Under the action of static electricity, the powder will be evenly adsorbed on the surface of the workpiece to form a powder coating. The coating is leveled and solidified after high-temperature baking. Form a sprayed surface. 3. Hot-dip galvanizing + spraying Hot-dip galvanizing + spraying process is to first perform hot-dip galvanizing and then spray. This effect is better than the first two anti-corrosion effects. Of course, the cost is also high.
