Color Coated PPGI Steel Coil 0.50mm Full Hard Prepainted Galvanized

Shandong Fulilai Steel Group has delivered high-quality, long-lasting pre-painted steel sheet and painted steel coils with a high-grade finish that is uniform in color, gloss, texture and thickness. These durable products combine the strength of steel, the protection against corrosion and the beauty of color into the ideal product for you. Our prepainted steel products are available in a variety of material thicknesses, widths, and lengths as we offer multi-blanking and slitting services.

Galvanized plate and aluminum zinc plate difference: Galvanized plate and galvanized plate mainly lies in the difference between the coating, galvanized plate surface evenly distributed a layer of zinc material, the base metal plays an anode protection role, that is to say, zinc material substitution corrosion protection of the use of the base metal, only when all the zinc corrosion can be damaged to the inside of the base metal The surface coating of the aluminized zinc plate is composed of 55% aluminum,43.5% zinc and a small amount of other elements. The surface of the aluminized zinc coating is honeycomb structure, which is composed of aluminum Containing zinc, in this case, aluminium zinc plating coating has anodic protection role, but on the other hand due to the shrinking of zinc content on the one hand, because of the zinc material by aluminum bag not the role of electrolysis anode protection so greatly reduced, so once the aluminium zinc plate is cut, the cut off the edge of the protection of basic loss was will soon be under the condition of corrosion, so aluminium zinc plate should be as little as possible Cutting, once cutting after the application of anti-rust paint or zinc rich paint to protect the edge, to make the plate life extension

Prepainted steel sheet is coated with organic layer, whichprovides higher anti-corrosion property and a longer lifespanthan that of galvanized steel sheets.
The base metals for prepainted steel sheet consist of cold-rolled, HDG electro-galvanized and hot-dip alu-zinc coated.The finish coats of prepainted steel sheets can be classifiedinto groups as follows : polyester, silicon modified polyesters,polyvinylidene fluoride, high-durability polyester, etc.

The production pro¢ess has evolved from one-coating-and-one-baking to double-coating-and-double-baking, and eventhree coating

The color of the prepair & ed steel sheet has a very wide selection,like orange, cream-colofed, dark sky blue, sea blue, bright red,brick red, ivory white, porcelain blue, etc.

The prepainted steel sheets can also be classified into groupsby their surface textures, namely regular prepainted sheets,embossed sheets and printed sheets.
The prepainted steel heets are mainly provided for variouscommercial purposes of architectural construction,electrical household applianges, transportation, etc.

Prepainted Galvanized Steel Coil/PPGI coating film introduction

Top paint film:

RPE, SMP, HDP,PVDF,Other paints.
Function: It functions as a sunlight proof cover, especially prevent the destroy by the ultraviolet rays. When the top paint film reaches a certain thickness, it forms a compact cover, and reduce the water and oxygen permeability.

Primer paint film:
Polyurethane, Epoxy, PE
Function:Strengthen the adhesiveness between the top paint film and the basemetal. Even permeable water happens, the top paint film will not peel off. There is corrosion inhibitor which is corrosion resistance. Polyurethane is necessary for higher processing flexibility and weather resistance requirements.

Passivation layer
Function:Increase the adhesion between the metallic layer and coating film. Extend life span also.

Metallic coating
Function:The metallic coating provides the fundamental protection for the steel.
The popular coating metal are galvanize, galvalume and other alloyed metals.

Substrate steel
Cold rolled steel is usually used as substrate, it decides the mechanical properties and the steel shape and flatness.

Back paint film
Epoxy, Modified PE.
Back paint can sustain color in good condition and has good binding.
