Introduction
In a country frequently exposed to heavy rains, intense heat, and strong typhoons, selecting a material that’s strong enough to withstand these weather conditions is essential when taking on a construction project. One such material is Galvanized Iron (G.I.) sheet, a metal sheet coated with protective metallic and organic coatings to prevent rust and corrosion.
G.I. sheets, also known as liso, have long been a cornerstone of construction and fabrication projects, from simple residential roofing to industrial warehouses and commercial structures. They provide a good balance of durability and versatility, hence their popularity among Filipino builders.
However, many builders often overlook one thing when it comes to choosing the right G.I. sheet supplier in the Philippines: the material’s size. Many prioritize price alone, therefore compromising the overall quality of their projects. In this article, we will walk you through choosing the right G.I. sheet gauge for your project, why they are essential, and how partnering with a reliable G.I. sheet supplier near you can help ensure your project’s integrity and longevity.
What Makes G.I. Sheets Essential in the Philippines Today
The popularity of G.I. sheets among builders in the Philippines relies heavily on their practicality and climate resilience. They are coated with a protective layer of naturally occurring metal, like zinc, which protects the steel underneath from rust and corrosion. This makes it an ideal material in a tropical, high-humidity environment, as well as in coastal areas.
G.I. sheets are also typically more affordable than other types of metal sheets for roofing and cladding, while still delivering dependable strength and durability. They are also widely available, with numerous G.I. plain sheet suppliers in the Philippines offering this material at competitive prices. The shift to more sustainable materials also fuels the popularity of G.I. sheets, as they are a long-lasting material that generates less waste over time.
These are just a few reasons why they are used in a variety of projects in the country, from small home renovations to large-scale commercial developments.
Which G.I. Sheet Size Suits Your Project Best?
G.I. sheets are measured in millimeters or gauge. Gauge refers to the thickness of the sheet. As a general rule, the lower the gauge or the higher the millimeter, the thicker and stronger the material is.
Choosing the right G.I. sheet thickness is essential in ensuring the longevity of your project. And to further ensure that you are getting quality G.I. sheets, you should check their sizes firsthand. To do so, you will need to use a micrometer to measure the thickness of its edges. You can also measure the middle portion of the sheet to ensure consistency in thickness.
Below is a breakdown of gauges available at most G.I. sheet suppliers in the Philippines, along with their common applications.
- 26 gauge (≈0.5mm)
26-gauge (approximately 0.5mm) G.I. sheets are among the thinnest sizes used in construction. They are lightweight, easy to transport, and simple to install. And because they are lighter, they are ideal for projects where minimal strength is required, such as residential roofing, light cladding work, and temporary structures, where heavy loads are not expected. - 24 gauge (≈0.6mm)
24 gauge (approximately 0.6mm) G.I. sheets are a step thicker than the former, so they offer more durability while maintaining their light weight. They are also used in medium-duty residential roofing, as well as automotive panels and siding. - 22 gauge (≈0.7mm)
22-gauge (approximately 0.7mm) G.I. sheets are well-suited for projects that need added durability. They can be used in warehouses or carports, as well as in industrial applications like HVAC ducts. They are also preferable for areas exposed to strong winds and rainfall compared to the previous ones. - 20 gauge (≈0.9mm)
Typically used in industrial and commercial applications, 20-gauge (approximately 0.9mm) G. I. sheets are significantly thicker and more robust. They are commonly used in large-span roofing, car body panels, metal enclosures, and even light construction projects. - 18 gauge (≈1.2mm)
Designed for heavy-duty applications, 18-gauge (approximately 1.2mm) is often used as material for gates and doors, as well as structures that need more strength. - 16 gauge (≈1.5mm)
16-gauge (approximately 1.5mm) G.I. sheets offer exceptional strength and load-bearing capacity. This is why they are used in industrial fabrication, heavy structural supports, fences, and cladding work that needs high resistance to impact. - 14 gauge (≈1.9mm)
This is among the thickest sizes available at G.I. sheet suppliers in the Philippines. A 14-gauge (approximately 1.90mm) sheet is commonly used in industrial shelvings, heavy machinery, and even in constructing infrastructures and outdoor billboards.
When sourcing this material, it is important to note that sizes and gauges may vary depending on the G.I. sheet dealers near you. Therefore, it helps to inquire first about their size availability before purchasing. You can also ask the supplier if you can check the items at their warehouse first, to verify firsthand if they have the correct size you’re looking for.
