1) The Guardrail is High Intensity and Easily Assembled. 2) The Guardrail Surface is Hot Galvanized or PVC Coated,so it is Anti-corrosion, long service life. 3) The Guardrail is widely used,It is used in highway,river,bridge,road and so on. 4) The Guardrails can prevent runaway vehicles from China Prepainted Gi Steel Coil PPGI Color Coated HS Code. 7210700000. Product Description. PPGI & PPGL (prepainted galvanized steel & prepainted galvalume steel) also known as pre-coated steel or color coated steel coil, It is a product made of hot-dip galvanized steel sheet, hot-dip galvalume steel sheet, electro galvanized steel sheet, etc. After surface pretreatment, one or several layers
The use of hot-dip galvanized/galvalume steel strip for the substrate color coated steel strip in addition to zinc coating protection, zinc coating on the organic coating played a covering and protective role, to prevent rust, and the service life is longer than the galvanized strip, about 1.5 times. Cut Z60 To Z275 Zinc Coating Roofing Sheet Prepainted cut Z60 to Z27 Zinc coating prepainted steel coil . Main specification:Width:750mmto 1250mm Thickness:0.20mmto 1.0mm Zinc coating:Z60 to Z27 (120g/m2 to 275g/m2, double sides) Surface color:refer to RAL card Annual production:100, 000 MT/year Durable ZINC. International Zinc AssociationZinc coatings from this process are five to ten times thicker than continuously galvanized coatings and can offer long term outdoor protection in most environments. This resistance can vary from 20 years in an industrial site to over a century in a rural environment.
The appearance of the coating (matte gray, shiny, spangled) does nothing to change the corrosion protection of the zinc coating. Back to Top. 8. Can galvanized steel in service withstand high temperatures for long periods of time? Constant exposure to temperatures below 390F (200C) is a perfectly acceptable environment for hot-dip galvanized steel. Galvanized Steel Coil Shanghai AIYIA Industrial Co., Ltd.Galvanized steel coil is to immerse a thin steel plate in molten zinc, so that a layer of zinc is attached to the surface. It is an effective anti-corrosion method and can provide a long service life Selection of steel types and coatings for color coated Oct 29, 2020 · Now commonly used steel coil coating topcoat varieties are polyester (PE), polyurethane (PU), silicon modified polyester (SMP), fluorocarbon (PVDF), high weathering polyester (HDP), primer and back paint varieties are epoxy (EP) polyester (PE), polyurethane (PU) and so on. The choice of color is mainly to consider the match with the surrounding
The color coated steel plate using galvanized steel plate as the base plate, in addition to zinc protection, the organic coating on the zinc layer plays a covering and isolation function, which can prevent the steel plate from rusting, and has a longer service life than galvanized steel plate. The service life of steel plate is 50% longer than that of galvanized steel plate.
