Applications of Galvanised Steel Coils

Nov. 22, 2021

Hot-dip galvanized steel coils are available with a pure zinc coating through the hot-dip galvanizing process. It offers the economy, strength and formability of steel combined with the corrosion resistance of zinc. The hot-dip process is the process by which steel gets coated in layers of zinc to protect against rust. It's especally useful for countless outdoor and industrial applications.

 

Hot-dipped galvanized steel coil is made from steel plate, which is dipped into the dissolved zinc bath, with a zinc layer on the surface. It mainly adopts the continuous galvanizing production process. That means the cold rolled coils are put into the dissolved zinc bath for continuous galvanizing process.

 

Galvanised steel coils are a special type of steel coil used in many different applications in manufacturing and fabrication environments. Any type of steel coil is a flat material thin enough to be rolled into coils or wound into continuous rolls. It can also be spun flat and cut to any length or shape required. Galvanised steel coils help users to apply them to outdoor fabrication projects.

Galvanised 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 galvanised 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 galvanised 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.

 

Other uses of galvanised steel coils involve manufacturing environments where thicker coils are used to make smaller parts. The smaller parts are cut and shaped as they are rolled into the press. Galvanised steel coils can also be welded and stitched, so it can be used for different tank fabrications that do not involve corrosive materials. Due to the workability of the material and its natural resistance to elements that other types of steel or metal cannot withstand, the uses for steel in coil form are numerous and varied.
