Galvanized Steel: The Most Used Building Material

Galvanized Steel: The Most Used Building Material

When it comes to building houses, a lot of things come to mind – materials, material profiles, colors, aesthetics, and costs. There’s just a lot of options; and not to mention, the number of salespersons and marketers that just come right at you with information. The load of information is just debilitating, yet, at the end of the day, you are just left with more questions. 

But first and foremost, the right question is how are you going to cut through the dizzying proportions of information and choose what’s best for your project? You just came to right place. This article aims to give you a sound and clear analyzation of steel as roofing material

Though it’s true that there are a lot of ways you can work on materials these days and that many a number of developments on cheaper and stronger materials are already available, steel still remains
as the most dominant in the market worldwide and most present among construction sites.

What is Steel?
A steel is a construction material of the past, the present, and the future. There is still no replacement for steel as a construction material in terms of strength, cost, and applicability. As an alloy of iron and carbon and other elements, steel helps improve and increase durability, strength,  hardness, malleability, and elasticity and other mechanical and physical properties such as formability and thermal conductivity. There properties make steel an ideal go-to material because of its comparable low price and its accessibility.

What is Galvanized Steel? 
Galvanized Steel is basically a cold rolled steel that has been coated with zinc in a process called galvanizing. It is commonly referred to as “G.I.” or galvanized iron. Now there are a number of steel sheets available such as copper sheets, aluminum sheets, and the like, and you might ask, why should you favor galvanized steel sheets instead of its other counterparts?

That’s because galvanized steel, aside from its track record in durability, is infinitely recyclable and such factor makes it widely and easily available. In fact, most of the steel we use today is made from recycled materials; and, because its recyclability makes it plentiful, it also makes it more affordable

What is Galvanizing?

Galvanizing is the process of coating steel material with zinc or alloys of zinc and aluminum to protect it from corrosion. The coating then becomes the “sacrificial layer” or the part that gets firsthand exposure to external elements; thus, preventing premature rust and corrosion.

Aside from this, steel sheets are easy to fasten and quick to install. If installed correctly, galvanized steel can last for decades with minimal maintenance. They are also extremely fire resistant even though heat and sound can travel through steel sheet products with ease.

Here are more reasons why galvanized steel is the right material for your projects.

1. Durable
Steel roof ensures that the roof will last and protect you for the years to come. In fact, homeowners often cited longevity and strength as their primary reason for investing in metal. Its long history of withstanding elements including gusts of wind up to 140 miles per hour and inability to rust easily makes it a good investment specially that a piece of industrial steel is expected to last up to 20 years or even further if maintained regularly.

The unique metallurgical structure of galvanized coating that protects the steel core also gives outstanding resistance to damages that may be acquired in transport, erection, and service. Such characteristic ensures uncompromised performance of steel. Also, a steel metal, if installed properly and maintained regularly, can seal out water, withstand strong winds, and even resist fire damages.

2. Aesthetic Features
Pliability or formability is one of the strengths of steel. Such formability affects creativity; if a material is easy to work on, the ideas are limitless and designers won’t have to hold back on creating ambitious designs. For one, it is easier now to cop or create a certain look and make meaningful designs for individuals or various communities. You may even create a tiled effect, paneled effect or, classical corrugated looks without using too much energy

However, because of the unique steel metal properties, a wide array of colors, finishes, and shapes and many other variations are already available in the market. Although other roofing materials offer the same variety, steel are best in holding paint finishes well. In addition, the color doesn’t just fade easily. It can mimic nearly any look using multiple-layer factory finishes that ensure that the appearance is not only beautiful but long-lasting and durable. 

3. Fire-resistant
Steel is a non-combustible, fire-resistant material. It has been widely used in mass transportation services such as cars, ships, and planes for the same reason — it cannot aid in propagation or spread of fire. Fire tests have proven a number of times that even a loaded structural material made from steel has the ability to retain its strength even after exposure to fire. Such qualities are proven to prevent collapse and provide additional time for evacuation.

However, the opposite happens if any public system or structure would be built in any material that is poor in fire rating. Mass transport systems or public structures could easily cave in and put people in danger. In addition, steel is also relatively lighter in weight. Its lighter weight increases the structural integrity of a building helping professionals like architects and engineer maximize the design of the building without compromising its strength.

4. Economical
As mentioned, steel is more affordable. Not just because of recyclability, but also because it’s easier to maintain. It is also easier to set up and it’s easier to find steel services nowadays in the market. Now there might be cheaper products, but the truth is that you save better with steel if you consider maintenance costs. Steel roofs have been known to last more than 20 years if handled and maintained well. Just imagine the costs you’ll save if you don’t have to replace walling and roofing structures often.

Even in cases where the initial cost of galvanizing is higher than alternative coatings, galvanizing is almost invariably cheapest in the long run because it lasts longer and needs little maintenance.

5. Environment-Friendly
Steel is 100% recyclable. Compared to other materials that are dependent on fossil fuels and that require replacement every 12 to 20 years, steel sheet metals are more sustainable for a number of reasons. For one, steel roofing is infinitely recyclable; in fact, 25% of its components typically come from recycled materials. Second, a steel metal roof is so light that it can be installed directly without overburdening the roof’s structural support. Third and most important, steel is energy efficient and can translate to savings in monthly heating and cooling costs.

Metal roofs reflect solar radiant heat instead of absorbing it. If applied and installed effectively, you wouldn’t have to blast your air-conditioners as steel roofing already bounces off radiant heat. Such property can save energy cost by 25%. Even further, applying special reflective pigments to roofing can further minimize heat transfer.
