Full Hard 0.83mm Z150 Prepainted Steel Coil for Roofing and Structural Panels

Full Hard 0.83mm Z150 Prepainted Steel Coil for Roofing and Structural Panels

１．Product Overview

Full Hard 0.83mm Z150 Prepainted Steel Coil is a color coated galvanized steel coil used for roofing sheets, structural panels, flange plates, ship plates, container plates, and industrial building applications.

The product uses a galvanized substrate with 150g/m² zinc coating and a polyester paint system. The 0.83mm thickness supports applications requiring stronger panel rigidity, while the pre-painted surface provides corrosion protection, appearance consistency, and reduced secondary painting work during fabrication.

２．Technical Solution

The galvanized steel substrate provides corrosion protection through 150g/m² zinc coating. The top surface uses 15 Micron Polyester + 5 Micron Primer to improve surface appearance, adhesion, and weather resistance.

The back surface uses 7 Micron + 5 Micron Primer to improve reverse-side protection during storage, transportation, forming, and installation.

The full hard substrate is suitable for applications requiring higher stiffness and dimensional stability during roofing, structural panel, and container panel production.
