Stainless steel guardrails are mainly composed of hollow risers, which combine and assemble each other to protect them. However, the thickness of the wall of the stainless steel guardrail is strictly standard, and the thickness of the wall is 1.2mm according to the national standard. But the thickness of the riser does not have a strict national standard, but it should not be lower than 0.7mm.
Therefore, it is necessary to pay attention to the thickness of the stainless steel guardrail because it is closely related to the life and protection of the guardrail. In addition, with the progress of the polishing technology, stainless steel protection fence can also be polished to form mirror light, matte or other processing effect, and play a beautiful decorative role. And the logistics performance of the stainless steel guardrail determines its anti - load resistance.
Zinc steel balcony fence with no welding assembly form such a link with anyway, we compared with the old zinc steel fence, more convenient installation, also beautiful appearance. Moreover, the raw material of zinc steel is divided into fine layers. Its basic material is steel. First, the hardness reaches the standard. Then second layers of zinc steel alloy layer are made. The material is compact, with more delicate and stronger corrosion resistance.
The sublayer of the third layer is nontoxic and the corrosion resistance is added to another layer. Fourth pure zinc layer, make the material more difficult to break, more solid. The fifth layer of high zinc phosphating layer increases the adhesion of steel and coating. Sixth layers of color molecules with high temperature curing layer, anti ultraviolet, antioxidant and surface cleaning properties. Because of the six layers of material treatment, the guardrail is more strong and beautiful not corroding rust.
