914mm to 1250mm Width PPGL Steel Coil Galvalume Base Material with Unique Composition

Introduction

Color-coated coil is a product of hot galvanized plate, hot aluminum plated zinc plate, electrogalvanized plate, etc., after surface pretreatment (chemical degreasing and chemical conversion treatment), coated with one or several layers of organic coating on the surface, and then baked and cured.

 The base material of our coil is made of galvalume steel, which is a combination of aluminum, zinc, and silicone. This unique composition provides excellent corrosion resistance and durability. Because coated with a variety of different colors of organic paint color steel coil named, referred to as color coated coil.

Color-coated Steel Coil Advantages

1. Corrosion Resistance
The aluminum-zinc alloy coating applied to PPGL (Pre-Painted Galvalume) steel sheets acts as a powerful barrier against rust and degradation caused by environmental exposure. This advanced coating combines the corrosion-resistant properties of aluminum with the sacrificial protection of zinc, resulting in a synergistic effect that significantly extends the life of the steel substrate. Even when used in harsh environments—such as coastal regions with high salt content in the air or industrial zones with acidic emissions—this coating maintains its integrity. As a result, PPGL steel offers a reliable and long-lasting solution for structures exposed to aggressive atmospheric conditions.

2. Durability
PPGL steel sheets are engineered for long-term performance. When paired with a high-quality paint finish that resists fading, chipping, and chalking, these sheets can endure the effects of sunlight, rain, humidity, and other natural elements for decades. Under typical weather conditions, they require only minimal maintenance—usually limited to occasional cleaning and inspections. In many cases, PPGL sheets retain their structural and aesthetic qualities for over 25 years, making them a cost-effective option for both residential and commercial construction projects that demand a long service life.

3. Strength and Support
Despite being lightweight, PPGL steel sheets offer remarkable mechanical strength. They are capable of bearing significant structural loads without deforming, making them suitable for applications where both weight efficiency and load resistance are critical. Their high tensile strength and excellent rigidity allow them to withstand strong wind pressures and heavy roofing materials without compromise. This makes PPGL steel an ideal choice for use in commercial buildings, warehouses, and industrial facilities where durable roofing and wall cladding are essential for long-term operational safety and performance.

Color-coated Steel Coil Applications:

1. Roofing
PPGL steel is extensively used for roofing in industrial, commercial, and residential construction due to its exceptional corrosion resistance and long-term durability.

2. Cladding
Thanks to its high-quality color-coated finishes, PPGL steel is a popular choice for exterior wall cladding and facades, maintaining visual appeal and structural integrity for decades.

3. Rainwater Goods
PPGL steel profiles are widely used to fabricate rain gutters, downpipes, flashings, and other rainwater management systems, offering reliable weather resistance and longevity.

4. Industrial Siding
PPGL steel panels are an ideal solution for warehouses, factories, and agricultural sheds, combining impact resistance, fire safety (non-combustibility), and low maintenance.

5. Agricultural Buildings
PPGL sheets provide a cost-effective and weather-resistant solution for farm structures such as sheds, barns, and stables, ensuring protection against harsh environmental conditions.

Standard Seaworthy Export Packing:

Color-coated coils are typically packed and shipped in a way that ensures their protection during transportation and handling. Common types of packing include coil packaging with edge protectors and VCI (volatile corrosion inhibitor) paper, followed by secure bundling with steel straps or wrapping with plastic film.
