Description

JISG3302 SGCC Z80 0.5mm*1250mm Zin Coating 80G Galvanized Steel Coil Zero Spangle

Galvanized steel coil refers to a flat-rolled steel product that has been coated with a layer of zinc through a hot-dip galvanizing process. This process involves immersing the steel coil in a bath of molten zinc, which forms a protective zinc coating on the surface of the steel.

Galvanized steel coil is typically made from low carbon or mild steel, which is suitable for the hot-dip galvanizing process. The choice of substrate may vary depending on the specific application and desired mechanical properties.

The primary purpose of galvanizing is to provide corrosion resistance to the steel. The zinc coating acts as a barrier that prevents moisture and oxygen from reaching the underlying steel, thereby protecting it from rust and corrosion. The thickness of the zinc coating can vary based on the specific requirements and can be designated using terms such as Z80, Z120, or as per the applicable standard.

Application

Galvanized steel coil can be used outdoors as it has the natural ability to avoid rust or corrosion. The coil itself is usually available in different sizes. It may vary in width from 6 inches to 24 inches (15 cm to 51 cm) and up to 10 feet (3 m) when unfolded flat.

The galvanized steel coil used by most builders is usually used in roofing applications. There, it is used as a protective cover or barrier for ridges and valleys in roofing systems. The coil is laid flat on the roof and then bent into the crease at the top of the ridge or in the valley to protect the joints in the roof panels from exposure to the natural environment. It also creates a watershed for rainwater runoff and melting snow or ice.

When used on roofs, a sealant is usually applied to the underside of the coils. It is sealed before it is nailed to the roof. It prevents any watershed from seeping underneath the coil.

Other external applications of galvanized coils are usually formed at sheet metal brakes. There, the coil is cut to length and then bent and crimped at right angles and dimensions to form curbs or fascia for building elements that may be deteriorated by exposure to the outdoor elements. However, installers using coil should know in advance that these applications should not involve treated timber products, as the chemicals in treated timber can cause the coil material to decompose, etc.

FAQ

Q1: Can galvanized steel coil be oiled?

A1: Yes, it can be oiled. 8-20 grams per square meter. Oiling can prevent oxidation of galvanized sheet in a short time.
