Hot Dipped Galvalume Steel Coil Slit Edge GL Coil For Roofing Sheet / Construction

Hot Dipped Galvalume Steel Coil GL Coil Aluzinc Steel Coil For Roofing Sheet And Construction

Product Introduction

GL Coil, also known as Galvalume Steel Coil or Aluzinc Steel Coil, is a high-performance coated steel product made by hot-dip coating cold rolled steel with an aluminum-zinc alloy. The coating composition is typically 55% aluminum, 43.4% zinc, and 1.6% silicon, providing excellent corrosion resistance, heat resistance, and long service life.

Our Galvalume Steel Coil is widely used for roofing sheets, wall panels, steel structures, household appliances, sandwich panels, and industrial construction projects worldwide.

As a professional manufacturer and exporter, we supply high-quality GL Steel Coil with stable coating thickness, accurate dimensions, smooth surface finish, and strong processing performance.

Product Features

Excellent Corrosion Resistance

Galvalume coating provides superior anti-corrosion performance compared with traditional galvanized steel.

Long Service Life

Suitable for harsh outdoor environments with longer lifespan for roofing and building applications.

High Heat Reflectivity

Aluzinc steel reflects heat efficiently, helping reduce building temperature and energy consumption.

Strong Formability

Easy for bending, roll forming, stamping, and corrugation processing.

Smooth and Beautiful Surface

Uniform spangle and clean surface improve product appearance and coating adhesion.

Wide Application Range

Suitable for roofing sheets, wall cladding, structural panels, appliances, and industrial buildings.
