A zinc steel substrate is made of hot dip galvanizing steel variety of galvanized steel, the use of 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 C-type zinc steel fence pictures, have superior protection, self-cleaning and environmental protection, low-carbon green green living products reach the true sense of the state to promote on. For guardrail Product C type zinc steel fence, according to their characteristics Heilongjiang Park zinc steel fence steel fence C-type zinc production program, the use of automatic gun powder ensure uniform protection, the purpose of real-time monitoring of the quality of C-type zinc powder steel fence construction, to ensure product quality and stability. General pure polyphenol powder coating curing conditions surgery is 200 ℃, 10min, by adjusting the furnace temperature and conveyor speed to ensure curing temperature and the time the second is to ensure a certain thickness of the powder coating is preferably deposited on the surface of the workpiece; III. as soon as possible to ensure that the workpiece is evenly heated to accelerate the curing process is generally pre-bake temperature is go-140 ℃.
