When it comes to construction in the Philippines, galvanized iron sheets are a cornerstone material, valued for their strength, durability, and cost-effectiveness. However, they are not created equal. There are various types tailored to specific construction needs, from roofing and walling to industrial applications.

At Linton Incorporated, we provide a wide range of high-quality GI sheets that cater to the diverse demands of the construction industry. Read on to learn about the different types of GI sheets and how they can elevate your projects to the next level.

Traditional Galvanized Iron Sheets

Traditional GI sheets are a go-to choice for roofing, wall cladding, fencing, and general structure applications. This is due to the fact that they are produced by coating steel with a protective zinc layer through a process called hot-dip galvanization.

The zinc coating serves as a reliable barrier against rust and corrosion, ensuring that the sheets remain strong and long-lasting, even when exposed to moisture and harsh weather conditions.

Moreover, GI sheets provide excellent protection at a fraction of the cost compared to other corrosion-resistant materials.

Galvalume Sheets

Galvalume sheets provide enhanced corrosion resistance compared to traditional GI sheets. They are coated with a unique blend of aluminum, zinc, and silicon, offering superior protection against rust and oxidation.

The aluminum in the coating enhances heat and corrosion resistance, while the zinc adds durability, and the silicon improves overall coating adhesion. This combination creates a sheet that outlasts others, even in harsh environments like coastal areas, where exposure to salt and moisture is high.

Furthermore, these sheets reflect more sunlight than traditional GI sheets, helping to reduce indoor temperatures and improving energy efficiency. This makes them an ideal choice for roofing applications, especially in the Philippines, where the climate is often hot and humid.

Pre-painted Galvanized Iron Sheets

Pre-painted galvanized iron (PPGI) sheets combine the strength and durability of traditional GI sheets with an added layer of aesthetic appeal and extra protection. These sheets undergo a specialized coating process, where they are first galvanized and then coated with high-quality paint.

The paint layer enhances their appearance and provides additional resistance against corrosion, UV rays, and harsh weather conditions. As a result, PPGI sheets require less maintenance and offer a longer service life compared to uncoated GI sheets.

Available in a wide range of shades and finishes, they allow architects and builders to match the aesthetics of residential, commercial, and industrial structures. Whether used for roofing, wall cladding, or decorative facades, these sheets add both functionality and visual appeal to any project.

Corrugated Galvanized Iron Sheets

These sheets are among the most widely used type of GI sheets in construction, recognized for their distinctive wavy pattern. This design significantly enhances their structural strength and improves load-bearing capacity.

Their unique design allows them to withstand heavy impacts, high winds, and even extreme weather conditions—making them a reliable choice for roofing and wall cladding in residential, commercial, and industrial buildings.

Additionally, they are lightweight, making them easy to transport and install. Their versatility allows them to be used in various applications like agricultural structures and temporary shelters.

Ribbed Galvanized Iron Sheets

Ribbed galvanized iron sheets are designed with raised ribs or ridges, providing enhanced structural integrity and improved load distribution. This makes them an excellent choice for roofing, wall cladding, and various other construction applications.

The ribbed design significantly strengthens the sheets, allowing them to support heavier loads while retaining their lightweight properties. This combination of durability and ease of installation makes ribbed GI sheets a preferred material for projects that demand strength without sacrificing convenience.

Whether used in large industrial warehouses or for stylish home exteriors, they offer an ideal balance of durability, weather resistance, and aesthetic appeal, making them a wise and practical investment for any construction project.

Key Takeaway

Understanding the different types of GI sheets is essential for choosing the right material for your construction needs.
