Advantages and characteristics of zinc steel guardrail
March 28, 2023
Zinc steel guardrails refer to guardrails made of zinc alloy materials that are used in different parts and have different functions. Because the surface layer is treated with electrostatic spraying in the later stage, it has high strength, high hardness, exquisite appearance, bright color, etc. It has become a mainstream product used in residential quarters, factories, colleges, and road traffic. Traditional guardrails are made of iron bars, which require electric welding and other techniques, and are soft in texture, easy to rust, and single in color. Zinc steel balcony guardrail solves the shortcomings of the traditional guardrail, and the price is moderate, so it becomes the substitute of various traditional guardrail materials. Zinc-steel guardrails are assembled in a non-welded and interspersed combination (some processes require partial welding, but zinc supplementation must be done before spraying), the thickness of the base material is 2-3 times that of stainless steel, more than 500 colors are available, and the surface is made of Electrostatic spraying of polyester anti-oxidation powder enhances the anti-oxidation, anti-ultraviolet, weather and corrosion resistance of the guardrail. With zinc steel as the base material, the products used in building guardrail mainly include balcony guardrail, protective window, stair handrail, fence, fence, shutter, air conditioning fence and road guardrail. Industrial fences (such as factory fences, commercial site fences), agricultural fences (such as field fences, livestock fences), civil fences (such as building roof fences, fence walls, etc.), public facility fences (such as road separation fences), etc. . It is widely used.
The base material of zinc steel guardrail profiles is high-temperature hot-dip galvanized material. Hot-dip galvanizing refers to putting high-quality steel into a zinc liquid pool of several thousand degrees. After soaking for a certain period of time, the zinc liquid will penetrate into the steel and form A special zinc-steel alloy. The surface of the hot-dip galvanized material can be rust-free for 30 years in the field environment without any treatment. For example, high-temperature hot-dip galvanized materials are used for highway guardrails and high-voltage towers. The rust has been as long as 30 years, which solves the problems between rust prevention, beauty and safety for many years.
Zinc steel balcony guardrail accessories use modified high-strength engineering nylon with a service life of up to 50 years. Its strength and hardness are much higher than ordinary steel materials. It can withstand a pressure of more than 183MPA per square meter and a tensile force of 2729MPA. Can withstand high temperature below 220 ℃ without deformation and other advantages.
Zinc steel characteristics 1. The zinc-steel base material is galvanized steel of various specifications made of hot-dip galvanized steel strips. Using high-frequency welding technology, the welding is smooth and firm. 2. The zinc content of the surface of the zinc-steel galvanized pipe reaches 60-80mm/㎡, and it can be rust-free for 3-5 years at room temperature. 3. Zinc-steel products are deep-processed galvanized pipes. Zinc steel guardrail process: mechanical processing → chemical treatment (degreasing → ash removal → phosphating → passivation) → electrostatic spraying (→ curing (220 ° high temperature imitation enamel curing) after multiple processes, it can reach 20 years. rust 4. Zinc-steel products are characterized by no welding, and the fittings developed by Zinc-steel are combined with pipes to achieve aesthetics, firmness and applicability, and meet the standards of the American Fence Association. 5. The surface of the product is sprayed with powder. Its products are beautiful in shape, colors can be freely matched, the color is better than rainbow, no welding interspersed combination, strong protective function, self-cleaning and environmental protection.
