Zinc-Coated Steel Guard Fence Netting Assembly Process !
Zinc steel guardrail refers to the balcony guardrail made of zinc alloy material, because of its high strength, high hardness, beautiful appearance, bright color and other advantages, has become the mainstream product used in residential areas. The traditional balcony guardrail uses iron bars and aluminum alloy materials.
It needs to use electric welding and other technology, and the texture is soft, easy to rust, and the color is single. Zn-steel balcony guardrail perfectly solves the shortcomings of traditional guardrail, and the price is moderate, and it has become an alternative product for traditional balcony guardrail materials ！
Introduction
Zinc steel Fence refers to the use of zinc alloy materials for different parts, with different functions of the fence, due to its later use of electrostatic spraying surface layer, so that it has high strength, high hardness, beautiful appearance, bright color and other advantages, become the mainstream product used in residential areas, factories, colleges, road traffic and so on. The traditional guardrail uses iron bar materials, which need to use technology such as electric welding, and the texture is soft, easy to rust, and the color is single. Zn-steel balcony guardrail perfectly solves the shortcomings of traditional guardrail, and the price is moderate, and it has become an alternative product for traditional guardrail materials. Zinc steel guardrail is assembled by weldless penetration combination (there are also processes that require local welding, but to do zinc supplementation before spraying), the substrate thickness is 2-3 times that of stainless steel, more than 500 colors are available, and the surface is electrostatic sprayed with polyester antioxidant powder, which enhances the oxidation resistance and ultraviolet resistance, weather resistance and corrosion resistance of the guardrail. With zinc steel as the base material, the specific products used in building guardrail are: balcony guardrail, protective window, stair handrail, fence, garden fence, blinds, air conditioning fence, road guardrail. Industrial fences (such as factory fences, commercial site fences), agricultural fences (such as field fences, livestock fences), civilian fences (such as building top fences, fence walls, etc.), public facilities fences (such as road barriers) and so on. It is widely used ！
Zinc steel guardrail profile substrate for high temperature hot dip zinc material, hot dip zinc refers to the high-quality steel into a few thousand degrees of zinc liquid pool, after soaking for a certain time, the zinc liquid will penetrate into the steel, so that it forms a special zinc steel alloy, hot dip zinc material surface without any treatment in the field environment can reach 30 years without corrosion, such as: Highway guardrail, high voltage tower is the use of high temperature hot dip zinc material, its rust prevention for 30 years, completely solved the problem between rust prevention, beauty and safety for many years.
Zinc steel balcony guardrail accessories with a service life of up to 50 years of modified high-strength engineering nylon, its strength, hardness is much higher than ordinary steel materials, per square meter can withstand more than 183MPA pressure, 2729MPA tensile force, can withstand 220℃ high temperature without deformation and other advantages.
Technology
1. Zinc steel balcony guardrail process: the use of solderless connection, horizontal and vertical interpenetration assembly. Compared with the traditional iron guardrail, the installation is faster and the appearance is more beautiful.
2. The base material of zinc steel balcony guardrail is composed of six layers, which are:
(1) Base steel: base material, hardness value of 159DPN;
(2) Zeta layer: a dense alloy layer closest to the substrate, complex structure, strong corrosion resistance, FeZn7 and FeZn13 combined existence, hardness value of 211DPN, Fe content of 7%-11%;
(3) Delta layer: significant monoclinic columnar structure, Fe content of 6%, non-toxic, corrosion resistance, hardness value of 179DPN;
(4) Pure zinc layer (Eta layer) : dense hexagonal crystal system, deformation processing is not easy to break, zinc purity 98.5%, hardness value of 70DPN;
(5) High zinc phosphating layer: has good corrosion resistance, and enhances the adhesion between the coating film and the substrate;
(6) High temperature curing layer: excellent corrosion resistance and impact resistance, with excellent UV resistance, oxidation resistance and surface self-cleaning properties, color change rate of 15 years does not exceed 5%.
