Galvanized PVC coated Zine Steel Decorative fence
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%
All of the fence panels, posts, mounting hardware and gates are
dipped in electracoat rust inhibitor after final assembly to
prevent corrosion and are then powder coated for a premium finished
product. Standard fences are in stock and shipping is more
affordable than you think! wrought iron fencing systems will not
only beef up the security of your residential or commercial
property but will improve the appearance as well.
