G350 Prepainted Steel Coil Painted Galvanized Color Steel Coil
Ppgi/ppgl(prepainted galvanized steel/prepainted galvalume steel)is coated with organic layer,
which provides higher anti-corrosion property and a longer lifespan than galvanized steel sheet.
The base metal for ppgi/ppgl consist of cold-rolled steel,hot dipped galvanized steel,electro-galvanized
steel and hot dipped galvalume steel. the coating material is as following :polyester ,silicon modified
polyester,polyvinylidene fluoride,high-durability polyester etc.
Application
♦ Buildings&Constructions
workshop, agriculture warehouse, residential precast unit, corrugated roof, wall,
rainwater drainage pipe, door, door case, light steel roof structure, folding screen,
ceiling, elevator, stairway,
♦ Transportation
inside decoration of auto and train, clapboard, container
♦ Electrical application
washing machine, switch cabinet, instrument cabinet, air conditioning, micro-wave oven

Advantage
Strong corrosion resistance, 3 times that of galvanized steel sheet.
The density of 55% aluminum is smaller than the density of zinc. When the weight is the
same and the thickness of the plating layer is the same, the area of the galvalume steel
sheet is 3% or larger than that of the galvanized steel sheet.
Color coated steel sheet is made by chemical pretreatment, preliminary coating and fine
coating, the quality of the coating is more even, stable and ideal than single spraying or
brushing on the surface of formed metal.
different surface types
quality control
We have strictly quality control for every batcg products.
we own the independent storage space, QC department, and the inspection room
of product features, we do the routine inspection for each kind product, and we test
mechanical property, paint performance, corrosion resistance, usage life etc parameters
for some products by our professional inspection room.
3 layers of package. Inside is craft paper, Middle is water plastic film and outside GI steel sheet to be covered
by steel strips with lock, with inner coil sleeve.
