Galvalume roofing is a type of roofing material that consists of steel coated with a mixture of zinc and aluminum. This coating, known as a "galvalume" coating, is applied through a hot-dip process, resulting in a resilient layer that combines the corrosion resistance of aluminum with the galvanic protection of zinc.

The resulting product offers excellent durability and weather resistance, making it particularly suitable for harsh environments like coastal regions where exposure to saltwater and moisture can accelerate the corrosion and degradation of traditional roofing materials.

Galvalume roofing offers several benefits:

Corrosion resistance: The zinc-aluminum coating provides superior protection against corrosion compared to traditional galvanized steel or aluminum roofing materials. This makes Galvalume roofing ideal for areas with high humidity, coastal environments, and areas prone to atmospheric corrosion.

Durability: Galvalume roofing is highly durable and long-lasting, with a lifespan ranging from 25 to 60 years depending on the specific environmental conditions and maintenance practices. It can withstand harsh weather conditions, including high winds, heavy rain, and snow.

Lightweight: Despite its durability, Galvalume roofing is lightweight, which reduces the structural load on buildings and makes installation easier and more cost-effective.

Heat reflectivity: Galvalume roofing has high solar reflectance, which helps in reducing heat absorption and keeping the building cooler during hot weather. This can contribute to energy savings by reducing the need for air conditioning.

Aesthetic appeal: Galvalume roofing is available in a variety of colors and finishes, allowing for customization to match the architectural style of the building. It provides a sleek and modern appearance while maintaining its protective properties.

Environmentally friendly: Galvalume roofing is made from recycled materials and is fully recyclable at the end of its lifespan, making it an environmentally sustainable choice for roofing.

Fire resistance: Galvalume roofing is non-combustible and offers excellent fire resistance, which can enhance the overall safety of the building and provide peace of mind to homeowners and occupants.
