Considerations
Customer Guide
When deciding between steel or aluminium corrugated sheeting for your home in Ireland, it is essential to factor in Ireland’s unique climate, your budget, and the long-term durability of the materials. Ireland’s weather, characterised by frequent rainfall and coastal influences, makes corrosion resistance and wind endurance critical considerations for roofing materials.
Steel Corrugated Sheeting
Durability and Strength
Steel’s robustness helps protect your roof and walls from damage caused by high winds or falling debris, making it ideal for an Irish climate. Cordion steel is coated with a unique 10-layer system, which further enhances its durability and resistance. The steel sheeting features a factory-applied protective film that helps safeguard it from scratches during installation.
Corrosion Resistance
With the proper coating, such as Cordion’s 10-layer form, steel can withstand the challenges of Ireland’s climate. While it may not have the inherent corrosion resistance of aluminium, regular maintenance ensures that steel roofing can have a long lifespan, even in coastal areas.
Cost
Steel is generally more affordable than aluminium, making it a cost-effective option for homeowners, especially those on a budget. If managing costs is a priority, steel sheeting provides a good balance between performance and price.
Aluminium Corrugated Sheeting
Robust Performance
Aluminium is lighter than steel, placing less strain on the structure of your home. This is particularly beneficial for older buildings that may not have been designed to support heavier materials. Cordion offers a structural-grade aluminium in dark red and matt black colours, which is more robust than standard aluminium. It features a textured finish, which naturally enhances its resistance to scratches and surface damage.
Corrosion Resistance
Aluminium naturally resists rust, making it an excellent option for Ireland’s coastal regions, where salty air and high humidity can promote corrosion. While aluminium does not rust, it does undergo oxidation, which results in a dull, chalky appearance. This oxidized layer acts as a natural protective barrier against the elements.
Cost
Aluminium sheeting tends to be more expensive than steel. However, for coastal homes or in areas with high moisture, the additional cost may be justified by lower maintenance needs over time.
Conclusion
Steel: If you live in an inland area and are looking for a more cost-effective material that provides strength and impact resistance, steel is an excellent option. With the right protective coating (such as Cordion’s 10-layer form), steel sheeting can last for many years with proper care and maintenance.
Aluminium: Although aluminium is more expensive, its natural corrosion resistance and lower maintenance requirements make it a superior choice for homes located in coastal or high-moisture regions. The structural-grade aluminium from Cordion addresses concerns about denting and provides greater durability.
In the end, the choice between steel or aluminium corrugated sheeting will depend on factors like your home’s location, the environmental conditions, and your budget. Steel is a strong, affordable option for inland areas, while aluminium is ideal for coastal or high-moisture areas, offering exceptional durability and low-maintenance benefits. Both materials are reliable and long-lasting, so your decision should align with your specific needs, ensuring both functionality and aesthetic appeal for your roofing project.
