Galvalume Corrugated Metal

Galvalume (pronounced “gal-va-LOOM”) refers to a type of coated steel roofing specifically designed to withstand corrosion in harsh weather conditions. The zinc provides galvanic corrosion protection, while the aluminum acts as a sealer. Together they create a durable, self-healing alloy finish that is highly resistant to rust and degradation from things like acid rain, salt air or other corrosive environments.

Galvalume steel coil is aluminum zinc alloy structure it is made by 55% aluminum, 43.4% zinc and 1.6% silicon,at 600ºChigh temperature solidification and composition,its whole structure by aluminum-iron-silicon-zin, which our galvalume steel has excellent corrosion resistance. We can also offer the service of cutting and punching. We are very capable to custom make for you.

Application

Galvalume roofing systems offer property owners durable protection from harsh weather across a variety of commercial buildings. Though most recognized for its use in low-slung warehouses and industrial structures, this versatile metal material finding new applications each year.

Agricultural facilities have long utilized galvalume’s corrosion resistance above large span barns, coops and equipment storage. Its ability to stand up to the elements over decades reduces maintenance costs for farmers. Feed mills, grain elevators and other operational buildings also benefit.

In coastal regions, galvalume wins favor through its resistance to saltwater air that causes standard steel roofs to rot prematurely. Marine industries install it atop shipyard hangars, retail beach shops and more to shield structures across shoreline communities.

Even homeowners have gained access to galvalume’s strengths lately. Rustic mountain cabins, Mediterranean-style villas and multi-family dwellings flaunt its structural integrity and beauty and lengthy warranties ease property owner concerns.

Wherever a durable, low-maintenance roofing solution proves vital, galvalume corrugated panels answer the call through their weather-tested history. Their versatile applications continue growing along with new project needs and designs.
