Cold Rolled Prepainted Galvanized Corrugated Steel Coil Color Coated Iron Roofing Sheet PPGI/PPGL


Baiyong Steel

PPGL Sheets are prepared by combining the strength of steel with anti-corrosive capabilities of a metal coating like Zinc or Aluminium. It is exceptionally resistant to weather and environmental degradations and can be punched, pressed, roll-formed, or joined in any way possible per requirement. They are made in a variety of specifications to suit different applications. They are lightweight and strong for easy placement and to provide high durability. They do not crack under pressure and are made to superior quality. Our suppliers provide PPGL Sheets made using the finest machinery and highly skilled engineers. Our product is superior in quality and has a fine finishing. The steel is properly galvanised to meet industry standards and the aluminium coating is made to display high strength and tolerance.

Some of the applications of PPGL Sheets include  Lining for Oil Tanks, in Factories, Educational Institutions, and Labs. Nuclear Power Plants, Electricity Boards, and Refineries (mainly, DM Water Plants) use PPGL Sheets.

The difference between galvanized sheet and aluminized zinc sheet mainly lies in the difference of coating. A layer of zinc material is evenly distributed on the surface of galvanized sheet, which plays the role of anode protection for the base metal. In other words, the substitutive corrosion of zinc material protects the use of the base metal.

Aluminium zinc plate the surface of the coating is composed of 55% aluminum, 43.5% of the zinc and small amounts of other elements, aluminum zinc plating coating under microscopic surface for honeycomb structure, composed of aluminum in the "honeycomb" 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 the plating aluminium zinc plate should be cut less as far as possible,Once cut with anti-rust paint or zinc-rich paint to protect the edges, the life of the plate can be extended.
