I. INTRODUCTION steel zinc galvanized steel, also known as zinc alloy zinc steel fence refers to the use of zinc alloy material balcony fence, because of its high strength, high hardness, attractive appearance, bright color, etc., has become a mainstream product used by residential area. The traditional use of iron balcony rails, aluminum material, by means of welding and other technology needs, and soft texture, easy to rust, a single color. Zinc steel balcony rails perfect solution to the shortcomings of the traditional fence, and low prices, as an alternative to the traditional balcony fence material products. (1) zinc steel zinc steel fence composed by the substrate and accessories. Zinc steel substrate zinc steel balcony railing fence sections for high-temperature hot-dip zinc material, hot-dip zinc refers to the quality of steel into molten zinc thousands of degrees of the pool, soak up some time after the zinc solution will penetrate into the steel, so as to form a special zinc alloy steel, hot-dip zinc surface without any treatment in the wild environment, can be up to 20 years does not rust, such as: highway guardrail, high-temperature high-voltage towers are hot dip galvanized material its anti-rust for 30 years, completely solve the problem for years anti-rust, beauty and security. Zinc steel balcony railing accessories using life of up to 50 years of high-strength engineering modified nylon, its strength, hardness much higher than ordinary steel materials, per square meter can withstand more pressure 183MPA, 2729MPA tensile strength, below 220 ℃ can withstand high temperature deformation and other advantages. ? (2) a zinc steel process, zinc steel balcony railing technology: solderless connection, anyway interspersed assembled. Compared with the traditional iron fence, install more efficient, more beautiful appearance. 2, zinc steel balcony railing of the substrate composed of six layers, namely: (1) steel layer (Base steel): substrate hardness value 159DPN; (2) zinc steel alloy layer (Zeta layer): the closest base alloy layer a layer of dense material, the structure is complicated, strong corrosion resistance, and to FeZn7 FeZn13 compounds exist, hardness values ??211DPN, containing Fe 7% -11%; (3) sub-layer of lead (Delta layer): significant columnar organization of the monoclinic system, Fe content of 6%, non-toxic, corrosion resistance, hardness value 179DPN; (4) pure zinc layer (Eta layer): dense hexagonal, texturing easy to break, the purity of 98.5% zinc, hardness value 70DPN; (5) high zinc phosphate layer: a good corrosion resistance and enhanced adhesion coating and the substrate; (6) Akzo - Nobel color temperature curing from molecular 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. Second, the characteristics of zinc steel zinc steel balcony railing has the following characteristics:? 1, solderless assembly design, installation quick and easy. ? 2, four anti-corrosion treatment, more than two decades of life, to solve the traditional product in a short time corrosion, chalking, cracking and other problems, eliminating the costs of product maintenance updates. ? 3, good decorative, rich colors, to meet different customer demand for personalized products. ? 4, environmental protection, do not pollute the environment, to solve the common problem of contaminated buildings. ? 5, good flexibility, performance, and flexibility of the substrate steel guardrail product has good impact resistance. ? 6, imitation porcelain pond surface treatment process of electrostatic spraying, so guardrail product has good self-cleaning properties, rain erosion and water cannons to spray clean as new. ? 7, buried under the mounting feet and ground-mounted, which saves you the cost of building the foundation, but also saves land resources. ? 8, good weather resistance, salt spray resistance and heat-resistant properties, suitable for use in different regions. Steel stamping parts, stamping parts fence fittings 40t 35t 32t fitting joints 45t u-type card connector bracket 30 * 40LN 35LN few stand Dian three bracket 40, a zinc steel product characteristics, the substrate is made of hot dip galvanized steel variety galvanized steel, using high-frequency welding technology, welding flat, firm. 2, zinc galvanized pipe pipe surface to reach 60-80mm / m, at room temperature can be 3-5 years without rusting. 3, zinc galvanized steel pipe products are put through many processes to deal with again deep processing. Process: machining → chemical treatment (degreasing → go gray phosphate → passivation) → electrostatic spraying (Akzo Nobel Powder Coating) → curing (220 ° high temperature curing imitation enamel) after multi-channel technology deal more can be achieved 20 years without rusting 4, the biggest feature product is no welding, faction 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 powder coating surface with Akzo Nobel, Akzo (Fortune 500 companies) specified long-term strategic partnership, 20 years of quality assurance, all products by faction within the normal life free maintenance. 6, and its products attractive appearance, color can be free with a rainbow of color to win, no welding interspersed combination with superior protection, self-cleaning and environmental protection, low-carbon green green living products reach the true sense of the state to promote on. 7 ,? fence balcony rails recognized industry experts said the multi-faction of zinc for the design of steel profiles Co., finds that the design meets the perfect combination of mechanics and aesthetics; four, apply color a zinc steel, common colors: black matte ivory grass dark green, sky blue, black and bright pink light pink two special colors:?? champagne bronze imitation copper powder can be adjusted according to the special five-color, zinc zinc steel balcony steel specifications: 30 * 60 pipe surface, a variety of side balcony guardrail pipe 40 * 80, 40 * 80 side balcony pipe cross tube 19 32 * 32 square tube, glass balcony faces the tube 30 * 60, 35 * 35 groove tube, 40 * 40 columns, 30 * 60 40 * 40 20 * 40 Plum tube, 30 * 60 40 * 40 30 * 40 22 * ??22, fence specifications: fence divided, two cross bar cross bar 3 3 4 cross bar cross bar plus spent four cross bar with double flowers divided according to specifications: 32 * 32 35 * 16 square tube equipped with 19 35 30 * 40 square tube with 22 square tube 30 * 40 40 * 40 tube equipped with 22 25 45 * 45 square tube with 25 square tube 32 * 32 32 * 32 with 22 pipe with 12 * 25 35 * 35 with oval tube 22 with the tube 30 * 40 40 * 19 square tube 40 with six 19 square tube, the main purpose of the use of zinc-galvanized steel steel steel doors zinc, zinc steel fence, zinc steel fence, zinc steel stair railing, galvanized steel fittings, galvanized steel profiles, galvanized steel protective window Six, a comprehensive summary of galvanized steel, replacing the traditional wrought iron rust problem. 2, the integration of green technology, creating new vision of new ideas. 3, technology and innovation as a guide to improve more employment.
