Galvanized metal fence _ San Ye Qu _ galvanized metal fence provided by the San Ye. Galvanized fence | San Ye metal | galvanized guardrail price is Linqu San Ye Metal (www.shengyehl.com) 2014 upgrade been newly introduced in the general atmosphere galvanized zinc layer fence surface to form a thin and dense layer on the surface of zinc oxide. It is difficult to dissolve in water, so the substrate steel fasteners play a protective role. If zinc oxide and other identity atmospheric heat generated after Weifang insoluble zinc galvanized guardrail, then anti-corrosion better; with zinc - iron alloy alloy layer, combined with dense salt spray performance in the marine and industrial atmosphere atmospheric unique corrosion resistance; due to a combination solid, zinc - iron solubility, has a strong resistance to abrasion; Because zinc alloys have good ductility steel substrate layer and firmly attached, it can be hot dip galvanized cold-rolled, drawing, bending and other forming processes, does not damage the coating; steel structure after hot-dip galvanized zinc fence Qu, equivalent to a galvanized fence annealing process, which can effectively improve the mechanical function of the steel substrate to eliminate steel stress molding welding pieces of steel structures in favor of turning; fasteners hot-dip zinc surface after a bright and beautiful; pure zinc layer is the richest hot dip zinc galvanized coating layer of plastic, the nature of the basic almost pure zinc has good ductility. Identification based on non-premium grade galvanized fence galvanized steel galvanized steel quality requirements from the perspective of its examination consists of two aspects, one is the appearance of quality, the second is the quality test. Appearance quality galvanized fence inspection, including packaging, dimensions, weight, surface appearance, etc.; galvanized guardrail quality inspection, including galvanized, mechanical properties, chemical composition, etc. Therefore, examination and identification of non-quality product for galvanized fence is also the basis of these considerations.
