| Product Introduction |
Corrugated steel sheet (Roofing sheet) is a building material composed of sheets of hot-dip galvanizedmild steel or Galvalume steel,cold-rolled to produce a linear corrugated pattern in them. The corrugations increase the bending strength of the sheet in the direction perpendicular to the corrugations, but not parallel to them. Normally each sheet is manufactured PPGI pre-painted galvalume steel coil, effective width 800mm, metal corrugated roofing sheets in its strong direction.
There are three types of roofing sheet,hot dipped galvanized,galvamueand color coated,This roofing sheet is lightweight and easily transported. It was and still is widely used especially in rural and military buildings such as sheds and water tanks.

Units on a continuous cold-rolled strip steel or steel sheet,galvanized steel (electro galvanized,Pre-painted steel coil hot galvanized,Galvalume and cold-rolled plate) as the substrate, after surface preparation (degreasing and chemical treatment), PPGI pre-painted galvalume steel coil, effective width 800mm, metal corrugated roofing sheets by a roll coating method, applying one or more layers liquid coating, after baking and cooling the resulting sheet is coated steel.Pre-painted steel coil Since the coating can have a variety of colors, it is customary to coated steel is called color coated steel sheet (PPGI).

PPGI pre-painted galvalume steel coil, effective width 800mm, metal corrugated roofing sheets is the material which uses galvanized steel as the basic substrate metal. PPGI is prepainted galvanized steel, also known as precoated steel, coil coated steel,Pre-painted steel coil color coated steel etc.PPGI pre-painted galvalume steel coil, effective width 800mm, metal corrugated roofing sheets A galvanized steel sheet in coil form is cleaned, pretreated, applied with various layers of organic coatings which can be paints, vinyl dispersions, Pre-painted steel coil or laminates.PPGI pre-painted galvalume steel coil, effective width 800mm, metal corrugated roofing sheets are applied in a continuous process known as Coil Coating.The steel thus produced in this process is a prepainted, prefinished ready to use material.
