Advantages of Galvanized Corrugated Sheet. 1. High Toughness. Galvanized corrugated sheet combines steel strength with corrugated design, which makes it high in strength to withstand extreme weather, like heavy snow, wind, etc. Thickness will greatly influence the strength and durablity. Generally, the common thickness for roofing is 0.4- 0.6 mm.
The corrugated galvanized steel roofing has a double-sided coating weight of 20-700 g/m2 according to ASTM test. The most commonly used corrugated galvanized steel sheets for building applications are Z275 and Z450, and the galvanizing amount is 275 g/m2 (the minimum thickness of the single-sided coated of the steel sheet is 19 m) and 450g/m2.

PPGI Sheet, Roofing Sheet, Corrugated Steel Roofing Sheet manufacturer / supplier in China, offering Pre Painted PPGI Steel Corrugated Metal Roofing Sheets, Hot DIP Gi Dx51d G90 1.2 mm Metal Galvanized Steel Sheet (Q-BQB420-2009), Dx51d Z275 Galvanized Steel Sheet Ms Plates 5mm Cold Steel Coil Plates Iron Sheet and so on. Prepainted Galvanized Corrugated Sheet Metal Roofing Steel If corrugated galvanized steel sheets are used, it should not be lower than Z275, and its service life is much lower than that of AZ150. Therefore, Australia and other countries have clearly stipulated that if corrugated galvanized steel sheets are used as roofing (wall), Z450 must be used.
PPGI Sheets & Coils. According to the shape, we divide prepainted galvanized steel into coil and sheet. The thickness of our PPGI is from 0.12 mm to 1.2 mm. To make it easy to transport, PPGI sheets are often rolled up into coils. While for specific purposes, PPGI coils can be sheared and profiled into plain or corrugated steel sheets.
