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.
