Product Description
Characteristic
Zinc-steel base material is galvanized steel made of hot dip zinc-steel strip of various specifications, using high-end high-frequency welding technology, welding smooth, strong.
2, zinc steel galvanized pipe surface zinc content up to 60-80g, at room temperature can 3-5 years not rust.
3, zinc steel products is the galvanized pipe again deep processing.Zinc-steel guardrail technological process: mechanical processing → chemical treatment (go to oil → go to ash → nano ceramic → passivation) → electrostatic spraying (→ solidification 220° high temperature enamel solidification) after more than 20 years of processing can not rust
4, the biggest characteristic of zinc steel products is no welding, zinc steel developed accessories and pipe perfect combination, to achieve a beautiful, solid and applicable, in line with the United States fence association standards.
5. The surface of the product shall be sprayed with powder.Its product modelling is beautiful, the color can match freely, the color wins rainbow, does not have the welding penetration combination, has the super protection function, from the clean environmental protection, achieves the low carbon environmental protection green life product in the true sense which the country advocates.

Technology
Zinc-steel balcony guardrail technology: non - welding connection, horizontal and vertical penetration assembled.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, respectively:
(1) Base steel: Base material with hardness value of 159DPN;
(2) Zeta layer: a dense alloy layer closest to the substrate, with complex structure and strong corrosion resistance. It is composed of FeZn7 and FeZn13, with a hardness of 211DPN and Fe content of 7%-11%.
(3) Delta layer: significant monoclinal columnar structure, Fe content of 6%, non-toxic, corrosion resistant, hardness value of179DPN;
(4) Eta layer: dense hexagonal crystal system, deformation processing is not easy to crack, zinc purity is 98.5%, hardness valueis 70DPN;
(5) high zinc phosphating layer: good corrosion resistance, and enhance the adhesion of coating film and substrate;
(6) high-temperature curing layer: excellent anti-corrosion and anti-impact performance, excellent anti-ultraviolet,anti-oxidation and surface self-cleaning performance, the color change rate of 15 years not more than 5%.
