Galvanised steel is mild steel with a coating of zinc The zinc protects the steel by providing cathodic protection to the exposed steel, so should the surface be damaged the zinc will corrode in preference to the steel Galvanised steel is one of the most widely used products, used extensively in the building sector, automotive, agricultural and other areas where the steel needs to be protected from corrosion 

Hot-Dip Galvanizing or HDG is a process in which zinc bonds to steel at the molecular level to produce a four-layer corrosion-resistant finish. The first three layers are zinc-iron alloy layers that are actually harder than the base steel. The fourth or top layer is pure zinc.

Pre-painted Galvanized steel is a Galvanized steel with a number of paint layers and treatments in a carefully controlled environment in a continuous coil coating line.
Pre-painting can also be done on electrogalvanized coils and cold rolled coils depending on the end-use and application of the steel.

PPGI Steel Coil is better at corrosion resistance. Paint on hot dip galvanized steel make it decaorative and 

usually used to indoor and outdoor decoration. Service life of PPGI coils can up to 20 years without fading.(Zn 60g, 25um painted in top and 10um painted in back).Production meets the standard of EN10147 DX51D+Z, JIS G3312 CGCC, ASTM A755M A653M.

Pretreatment Types for Substrate Surface: Normal chemical pretreatment, Chrome free chemical pretreatment. Coating type: Top side two coats, bottom size one coat, Topside two coatings, bottom side two coatings, Topside two coatings, bottom side two coatings(Note: The thickness of bottom side coating is smaller than that of the product type 2/2).

The annual capacity of Color-coated Line is 240,000 tons. We could manufacture top grade steel sheet in building materials plate, automobile plate, electrical appliance plate, solar energy panel, high coating and corrosion resistant plate, MATT plate and plate used for windows and doors.

Coating Process

The process of Prepainted Steel Sheets: Uncoiling→Welding→Inlet Looper→Clearning→Chemical Treatment→Primary Coating→Baking of Primary Coating→Baking of Primary Coating → Cooling of Primary Coating → Finish Coating → Baking of Finish Coating → Cooling of Finish Coating → Outlet Looper → Checking → Stamping → Cutting → Coiling.
