Erosion Proof--Environment Friendly, Good Foerver

There's lack or defect regarding the erosion proff performance of bridgeframe surface treatment finished bu electroplating, plastic spraying and hot zinc-plating, so we independently developed VCI double metal compound surface coating technology, which fills up the very enhancing anti-erosion performance for the bridgeframe on long -term basis, Undergone 3000h salt fog test, 1000h chemical erosive gas(SO2)

Test, 240h acid0alkali medium test and 12-period alternative damp heat inspection, it remains no phenomenon of erosion, after comparison among the inspection data, such coating shows far superior erosion-proof performance which is pf more 20 times better than that of zinc-plating, As the repuirement for bridge surface erosion-proof repuirement the VCI double metal compound coating energy-saving bridgeframe will be definitely the optimal and unsubstitutable choice for engineering building.
