You may have come across the term “galvanization”, but what does it actually entail? Galvanization involves applying a layer of zinc to iron or steel to prevent corrosion. The most commonly used method is hot-dip galvanizing. This process involves submerging metal in a molten zinc bath to coat the metal and protect the metal. At Dura Roof, our roofing sheets are made of galvanized metal and offer some major, measurable benefits. Let’s take a closer look at some of them.

Low initial cost

Unlike other types of steel and treated steel, galvanization is one of the lowest priced steel treatments. Other standard coatings including specialised painting are much more labour intensive, so much so that application costs are as high or higher than the cost of factory operations. This results in an extremely high initial cost for contractors. However, with galvanized steel, contractors can significantly reduce their initial costs. Homeowners looking to replace their roof will also benefit from the cheaper rates.

Low maintenance

Apart from saving a lot of money on initial costs, galvanizing your steel is invariably the cheapest option for the long term. This is because galvanized steel lasts much longer than any other treated metal and requires the least amount of maintenance. Thus, galvanized steel helps you save a lot of money in the long run that would have been lost due to periodic repairs or maintenance costs.

Reliable performance

Through galvanization, your metal roof is treated with an application of protective zinc coating. This protects your metal roof from rusting and drastically increases the durability of your product. Even the most standard, minimum coating works to improve the performance of your material, making it much more reliable. Dura Roof’s galvalume roofing sheets are coated with 55% aluminium, 43.5% zinc and 1.5% silicon making them anti-corrosive, temperature-resistant and highly flexible. Even our colour-coated roofing sheets are guaranteed to last for decades without any fading, peeling or cracking.

Long lasting

Thanks to the zinc alloy coating, galvanized steel can stand the test of time – one of its biggest advantages. This is because the zinc layer corrodes first, sacrificing itself to protect the metal beneath. The by-products of zinc being corroded get deposited on the steel underneath and reseal it. This means external forces, no matter how harsh, will not be able to cause corrosion. In fact, several tests and studies reveal that galvanized steel will last well beyond 50 years in regular environment and close to 25 years in coastal regions or extreme environments. End users and contractors can use galvanized steel confidently in any of their projects as it will stay durable and resilient for several decades.

Total protection

The hot dip process used to galvanize steel ensures that every part of the product is protected from rusting and harsh environmental, including sharp edges and corners. Any other chemical coating process would not be able to reach every recess. Moreover, the galvanization process also protects the internal structure of steel underneath, helping it maintain its structural integrity.

Resistant coating

Galvanization is a unique chemical process that helps zinc bond with your steel products. Courtesy this process, your products are left with a tough and protective outer layer which provides an abrasion-resistant film. The coating itself has a unique molecular composition that will protect the steel underneath from damage during transportation, installation and service. You can be rest assured that your galvanized steel products can withstand sight damage, scratches and dents and will also stay sturdy during the speedy erection of structures. Dura Roof’s roofing sheets provide exactly these benefits. Apart from potential external damage, the resistant coating also protects your facility from excessive heat and light. Galvanized metal is capable of reflecting heat and light keeping your property cool.

Ease of use

Unlike other structural steel products, galvanized steel is ready for immediate use as soon as it is delivered. You don’t require any additional preparation time before beginning construction. Additionally, there is no inspection or additional coating or painting required. Once the structure is assembled, contractors can immediately begin the next stage of construction without any worry.

If you’re looking for durable materials for your next project that will stand the test of time, look no further than galvanized steel. And if you’re after metal roofing, then head over to Dura Roof. Our team of experts will help you make the right decisions through your roofing journey.
