Corrugated gi(galvanized) Sheet

Corrugated roofing is one of the best choices for homes that get a lot of rain. But even though you don’t live in areas not heavily rained on, corrugated roofing can still offer you a lot of benefits that can trump the benefits that other roofing such as tiles and asphalt shingles can offer.

Corrugated GI sheets are made from a fusion of metal panels. Depending on the manufacturer, they can be made from G-90, G-60, galvanized, stainless steel or aluminum sheets.

They are then shaped to form waves or ridges. After that, these panels will go into a process where they are corrugated or where the grooves are shaped. The corrugated shape will allow rainwater and even snow to effectively slide off of the roof.

Pros:

  • Longevity

Arguably the biggest advantage of corrugated GI sheets is their durability. They are designed to last for a lifetime, depending on how thick the panels are and what kind of coating was used to treat it.

In the past, galvanized steel is prone to rusting but with modern day corrugated GI sheets, that won’t happen anymore.

Additionally, these metal sheets are not prone to corrosion and to infestation. Unlike with other types of roofing where termites and other burrowing pests can get in and damage the material of your roofing, this is impenetrable to these pests.

Additionally, they also don’t decay overtime because these materials are not prone to the formation of molds, mildew and algae.

You can also find corrugated GI sheets today that make use of nanotechnology. This injects the ability to repel heat, which not only keeps the interior of your residential or commercial property cool but also prolongs the lifespan of your roofing.

  • Fire resistance

Corrugated GI sheets do not catch fire as easily as other traditional roofing materials. This is why it is a better choice for your home or residential property’s safety. It is also heat-resistant, great for countries with a warmer climate.

  • Easier to maintain

Corrugated GI sheets do not require as much maintenance as shingles or tile roofing. The external coating and chemical treatment prevent algae growth, which basically reduces the amount of maintenance work you need to do. And since it is impervious to termite attacks, you don’t have to worry about patching up small holes in your roof.

Cons:

  • Higher costs of installation

The biggest downside to this type of roofing is that it requires professional installation, especially if you are using the high-end ones.

If someone inexperienced installs the GI sheets, it can lead to leaks. It is also important to use the right fasteners recommended for the GI sheet you are buying. On the other hand, its lightweight features make up for the more rigorous installation.

  • Noise level

Although there is a higher level of noise with these metal sheets, it can be argued that other types of roofing also produce the same level of noise.

Additionally, you can also add noise-dampening features to muffle the sound of rain drops. Adding insulation and soundproofing is also possible.

Finally

Finding corrugated GI sheet suppliers start with deciding what you need.

What kind of roofing are you looking for? Do you already have a style and color in mind?

You need to first consider what your needs are before looking for suppliers.

The thickness of the corrugated GI sheet, the color and the design all contribute to the aesthetic and the functionality of your roofing.

You need to take into consideration durability and weather-proofing as well to make sure that the materials you will buy will last for a long time without the need for extensive maintenance.

Find a supplier that can deliver the material with the specifications you are looking for. Make sure they are industry experts and they are institutions that have been around for a long time now.

Credibility is important when it comes to expensive materials like roofing. Try to compare suppliers in terms of the products they can offer, the availability of the products, the speed of delivery and the price.

Whatever you choose, make sure you don’t choose price over quality. Try to find a middle ground if you are on a budget, to buy roofing materials that will last you for a lifetime.
