GPSP (Galvanized Plain Skin Pass) sheets are steel sheets with a hot-dip zinc coating for corrosion resistance. Key specifications include thicknesses from $0.30$mm to $3.15$mm, widths of $1250$mm, and lengths of $2500$mm (though other sizes are available). The galvanized coating is often specified in grams per square meter (GSM), with common grades being \(80,90,120,180,\) and \(275\) GSM.Key specifications for GPSP sheetsSpecificationDetailsMaterialGalvanized steel with a skin-pass surface treatmentCoatingHot-dip zinc coating for corrosion resistanceThicknessTypically from $0.30$mm to $3.15$mm, with some variations depending on the supplierStandard Size$1250$mm width x $2500$mm length (4x8 feet)Coating Weight (GSM)Available in various grades, such as \(80,90,120,180,\) and \(275\) GSMGradesGrades can be specified based on the base metal standard (e.g., IS 1079 or IS 513)IndustriesCommonly used in construction, automotive, and for various fabrication applications
