Steel Sheets – COIL MATERIALS

Raw Materials Specification

Steel Sheets

COIL MATERIALS

Internal and external facings of a sandwichpanel are determined according to the type of usage of the panels, type of the surronding enviroment and the loods affecting on the sandwich panel. The most common metallic facings of sandwich panels is PPGI (Pre-Painted Galvenized Iron).
