Galvanised vs. Galvalume Roofing Sheets: Know the Differences
When choosing the right roofing material for the commercial building, two popular roofing sheets options are galvanised and galvalume roofing sheets. Both of these materials have different characteristics and features that make them suitable for a variety of applications, so it is important to understand the differences between them to make the best decision for your project.
In this article, we will discuss the differences between galvanised and galvalume roofing sheets and their advantages and disadvantages.
Differences
The first difference between galvanised and galvalume roofing sheets is the material that they are made of.
● Galvanised roofing sheets
Galvanised roofing sheets are an excellent choice for those requiring a high-performance roof designed to last. Produced from steel or iron dipped in molten zinc, these sheets can last up to four times longer than other materials, making them the smart option for any serious building project. In addition, the sheets come in many different designs and profiles, adapting well to any roof construction, while their lightweight and cost-efficiency also work to their advantage.
● Galvalume roofing sheets
Galvalume roofing sheets are a highly durable roofing option due to their unique characteristics. Made out of steel or aluminium, an alloy of zinc and aluminium further strengthens these sheets. This coating combines the corrosion resistance of zinc with the sacrificial protection assistance of aluminium, meaning that it faces the elements with greater durability than other roofing solutions. With the classic look, flexibility, and powder finish options, galvalume is a prime choice for high-performance roofing materials.
Both materials provide a strong, long-lasting roof, but their performance has some differences.
Advantages
Here are the advantages of galvanised and galvalume roofing sheets:
The most significant benefits of galvanised roofing sheets are their low cost
and long-lasting durability. In addition, the zinc coating used in galvanised
roofing sheets offers excellent protection against rust and corrosion, making
them well-suited for coastal and industrial environments where the air is moist.
Galvalume roofing sheets offer similar protection from rust and corrosion.
Still, they can also reflect a significant amount of the sun’s UV rays, making
them suitable for applications where heat retention is important.
Disadvantages
Here are the disadvantages of galvanised and galvalume roofing sheets:
The main disadvantage of galvanised roofing sheets is their susceptibility to
damage from hail and other debris. In addition, the zinc coating can wear off
over time due to exposure to the elements, which means that galvanised roofing
sheets may need to be replaced more often than galvalume sheets. Galvalume
roofing sheets are also slightly more expensive than galvanised sheets, though
the price difference is relatively small.
Choosing between galvanised and galvalume roofing sheets will depend on your specific requirements. Galvanised sheets may be the best choice if you are looking for a low-cost option with excellent durability. However, if you need a material that provides heat reflection and superior protection from the elements, then galvalume sheets may be the better option. Ultimately, it is important to consider all variables to make sure you select a material that is right for your project. Metal wall cladding with either galvanised or galvalume sheets can be a great investment for any building and provide you with the perfect balance of protection and aesthetic appeal.
Be sure to buy roof sheets in India from a reputable supplier to ensure your roof is of the highest quality and will last for many years. So when you are ready to build or upgrade your roof, choose from galvanised or galvalume roofing sheets for a reliable and durable solution.
