G60 galvanized steel coil is a carbon steel coil that combines strength with excellent formability. The “G60” in its name refers to the zinc coating weight of 0.60 oz/ft². It uses cold-rolled steel strip as a substrate, and a hot-dip galvanizing process forms a strong protective zinc layer on the surface, resulting in excellent corrosion and rust resistance. It is used in building roofing, home appliances, and lightweight steel structures. Wanzhi Steel is a professional supplier of G60 steel coil. Our quality is ISO-certified, and we offer a smooth and uniform surface. We can customize widths and thicknesses, and we offer a variety of machining options.

Main Benefits

Balanced corrosion protection and surface performance

The moderate zinc layer thickness effectively protects against external corrosion; the smooth surface provides both protective and decorative properties.

Excellent processing and joining compatibility

The steel coil exhibits excellent plasticity and toughness, enabling smooth cold processing such as bending, stamping, and shearing without damaging the zinc layer. It also offers stable welding performance.

Customizable specifications

A wide range of sizes and customizable lengths meet diverse application needs. With a light and thermal reflectivity exceeding 0.70 and high-temperature resistance up to 315°C, it offers both energy efficiency and heat resistance.

High cost-effectiveness

While maintaining basic corrosion protection and mechanical properties, it offers low cost, achieving an optimal balance of performance and cost for non-extreme environments.

Application

Architecture and Structures

Used in building envelope systems such as roof panels, wall beams, lightweight steel purlins, brackets, and auxiliary components such as ventilation ducts and gutters. Its excellent formability and weldability facilitate construction.

Home Appliances and Light Industry Manufacturing

For example, it is used in the manufacture of housings, back panels, and internal structural components for products like refrigerators and washing machines. Its high surface quality allows for direct application of decorative treatments such as spraying, ensuring long-term rust protection.

Automotive and Transportation

For example, it is used in door reinforcements, seat frames, and chassis components. It contributes to lightweight vehicle bodies and effectively resists erosion from impacts caused by gravel and humid environments.

Agriculture and Storage

Used in agricultural greenhouse frames, silo walls, storage racks, and equipment protective covers. Its corrosion resistance withstands the harsh conditions of agricultural chemicals and storage environments.

G60 Galvanized Steel Coil Definition

G60 is a zinc coating grade designation based on ASTM A653/A653M. The “G” designation stands for zinc coating, and the number “60” represents the zinc coating thickness in ounces per square foot. Galvanized steel coil refers to carbon steel coil that is coated with a protective zinc layer using continuous hot-dip plating. G60 Galvanized Steel Coil means hot-dip galvanized steel coil with a total weight of double-sided zinc layer of 60oz/ft² or approximately 180g/m².

What Does Z60 Mean?

Z60 is a zinc coating grade designation based on GB/T 2518-2019. The “Z” designation stands for zinc coating, and the number “60” represents the zinc coating weight in grams per square meter.

Different Standards of Zinc Layer Representation

G60 GI Coil VS. Galvalume Steel Coil

Galvalume steel coils generally offer superior corrosion protection compared to G60 galvanized steel coils. Galvalume steel coils are coated with a zinc-aluminum-silicon alloy. The aluminum forms a dense oxide film that isolates corrosive media, and the alloy layer has stronger adhesion. In outdoor, high-humidity environments, the corrosion life of Galvalume steel coils can be 2-3 times longer than that of G60 steel coils. G60 steel coils are pure zinc, relying primarily on zinc sacrificial anodes for protection. While they provide basic corrosion protection, their weather resistance and resistance to harsh environments are inferior to those of galvanized steel coils.
