Cold-formed galvanized steel guardrails are after wave plate as base material, attached to the hot-dip galvanizing layer on its inner and outer surfaces, combining it with a solid base and long-term stability of the product. Hot dip galvanized steel guardrails matrix material is carbon steel, its mechanical properties and chemical composition index of not less than Q235 grade steel requirements GB/T700-1988, so it has good mechanical properties and impact resistance; surface zinc layer is 0 or 1 # # the ingot, hot galvanized firmly bonded manner to the base member together. The product is consistent uniform zinc coating, smooth appearance, a certain decorative properties. And with strong adhesion, high hardness, corrosion resistance and other characteristics is difficult. Technical parameters are as follows: galvanized thickness: average 85um, at any point of not less than 61um Appearance: uniform complete, consistent color, smooth surface practical, no-sag, drip tumors, lumps and other defects impact test: zinc layer does not peel off, not convex onwards, no cracking bending: no cracks, peeling and other phenomena zinc coating uniformity: 5 copper erosion, constant red salt spray: do not appear galvanized steel corrosion characteristics of a fence, rust, corrosion --- dip zinc layers, zinc-phosphate coating, electrostatic coating all have excellent rust effect, zinc steel fence in the harsh environment in general can guarantee 30-50 years without rusting. ? 2, weather resistance --- electrostatic spraying process uses a high-temperature curing powder made of solid, stable performance far this powder in liquid coatings, including paints, performance. So zinc steel fence has good resistance to UV protection, long-term exposure to sunlight basically will not fade. 3, the use of tamper tamper --- Accessories Installation, tamper fittings and tubing through national technical department, the targets are exceeded national standards. ? 4, rich colors --- rich designer colors to meet the individual needs of the railings adorn buildings, cars can reach enamel shell effects, including imitation wood color, as long as you press the Swatches palette we can production?. 5, delicate feel warm --- --- zinc steel fence can achieve smooth surface and matt surface and feel the effect of the two can achieve the same color is not the same feeling, giving the building more features and emotions. Zinc steel fence is widely used in residential gardens, offices and schools, factories and mines, roads, park attractions, River embankments, highways, sports facilities, hotels and entertainment venues? For different consumer demand.
