The purity of the coating is high, so the corrosion resistance of the
coating at the same thickness is better than that of hot-dip galvanized products.
According to the test, under the same conditions, according to the
American standard (ASTMB 114), the red rust resistance time of a micron
coating is 12 hours for electrogalvanizing and less than 10 hours for hot
galvanizing. However, it is very difficult to obtain a thick electro-galvanized
coating (large power consumption, high cost, and technical difficulty).
As a color-coated substrate, the use of electro-galvanized is also
mainly applied to home appliances, steel furniture, doors and windows, and the like.
We can also provide galvanized plain
and corrugated sheets with required length.
Galvanized corrugated sheet can be produced
with closed tolerance of standard depth, pitch and width.
PPGI corrugated steel roof sheets
widely used in construction,
factory,simple house.Its easy installation,
beautiful view,light weight is more popular with people.
Pressed corrugated steel sheet (roofing sheet) refers to the steel sheet formed by cold pressing or cold rolling.
The steel sheet is made of coloured steel sheet, galvanized steel sheet, stainless steel sheet, aluminium sheet,
anticorrosive steel sheet or other thin steel sheet. The profiled steel sheet has the characteristics of light weight,
high strength, low price, good seismic performance, fast construction and beautiful appearance.The corrugated
metal is a good building material, mainly used for guardrail, floor and other buildings, such as airport terminal,
railway station, stadium, concert hall, grand theatre, etc. According to different application requirements, the
profiled steel sheet can be pressed into a wave type, a T type, a V type, a rib type and the like.
Corrugated steel sheet is also called profiled sheet,
which is made of color coated steel sheet, galvanized
sheet and other metal sheets by rolling and cold
bending into profiled sheets of various wave shapes.
