Product Name: Iron railings 001 Update Time: 2013.08.31 Views: Details / Details wrought iron fence, zinc steel fence a zinc steel substrate is made of hot dip galvanized steel variety of galvanized steel, the use of high-end high-frequency welding technology, welding flat, firm. 2, zinc galvanized steel pipe surface galvanized pipe reach 60-80mm / m, at room temperature can be 3-5 years without rusting. 3, zinc galvanized pipe steel products is to re-processing. Zinc steel guardrail process: machining → chemical treatment (degreasing → go gray phosphate → passivation) → electrostatic spraying (→ curing (220 ° high temperature curing imitation enamel) after processing multi-channel technology can reach 20 years without rusty 4, the biggest feature is no welding galvanized steel products, galvanized steel and pipe fittings developed the perfect combination to achieve beautiful, strong and suitable for compliance with US fence Association standards. 5, the product surface with powder coating. Its products handsome in appearance, Colors can be free with rainbow color wins, no welding interspersed combination with superior protection, self-cleaning and environmental protection to achieve low-carbon green green living products on the true meaning of the state to promote the craft: 1, zinc steel balcony railing process: solder-free connection, anyway interspersed assembled relative to traditional iron fence, installing more efficient, more beautiful appearance 2 zinc steel balcony railing of the substrate composed of six layers, namely: (1) steel layer (Base steel): a substrate, hardness values ??159DPN; (2) zinc-steel alloy layer (Zeta layer): a layer closest to the base alloy layer is dense, complex structure, strong corrosion resistance, and to FeZn7 FeZn13 compounds exist, hardness value 211DPN, containing Fe 7% -11%; (3) sub-layer of lead (Delta layer): significant columnar structure of monoclinic system, Fe content of 6%, non-toxic, corrosion resistance, hardness values ??179DPN; (4) pure zinc layer (Eta layer): dense hexagonal, texturing easy to break, zinc 98.5%, the hardness value 70DPN; (5) high zinc phosphate layer: a good corrosion resistance, and enhanced coating film and substrate adhesion; (6) high temperature curing layer: excellent corrosion resistance and anti-impact performance, with excellent resistance to UV, anti-oxidation and surface self-cleaning properties, color change rate does not exceed 5% for 15 years Advantages: (. 1) Security: high strength zinc alloy, heat treated after forming T5 and unique design, integrally molded, no joints, greatly increasing the overall strength (2), aesthetics: streamlined appearance, soft colors, to coordinate the surrounding landscape, can integration of modern urban space and the natural environment, so you swimming among the (3), comfort: looking off, enjoy the scenery, to provide you with a comfortable and secure platform (4). practicality: a special surface treatment process, the formation of a permanent protective film, smooth, never rust, easy to clean, no maintenance (5), weather resistance: This product features in its aluminum surface after special processing, so no matter air pollution in urban areas or coastal sea salt corrosion, can ease to use, to solve your worries maintenance products both practical and decorative, can be used in family homes, gardens, villas, enterprises, institutions, municipal, park facades fence. can be customized according to customer requirements specifications. Products using hot galvanized steel production, with strong corrosion resistance, high temperature resistance, excellent resistance to heat, basic requirements low, long life, green. Products can be customized according to the height and width of the product. You can also choose the color according to their preferences.
