Libya 210 Tons PPGI Coils Project

Following the Azerbaijani customer’s purchase of 50 tons of PPGI coils, after several rounds of negotiations, the Libyan customer purchased 210 tonnes of RAL 9003 color coils from Wanzhi Steel, which had been completed and sent to Libya on 18 May 2023. Libya is a stable source market for Wanzhi. Customers are very satisfied with the quality of our products. We offer all RAL colors, and we can also customize the colors for you. The following is the cooperation record of this project

Production Process

PPGI Meaning

PPGI coil is short for pre-painted galvanized steel coils and is made of galvanized steel coil after surface coating treatment. Its surface is coated, can be customized according to customer needs, has a variety of colors, beautiful, anti-corrosion, and weather resistant can be good. The pre-painted galvanized coil is widely used in construction, home appliances, automobiles, electronics, and other fields.

What is The Purpose Of Galvanizing?

1. Prevent corrosive substances: The zinc coating on galvanized metal prevents corrosive substances from reaching the weaker underlying substrate metal. This can extend the service life of the substrate, especially in demanding applications.
2. Prevent rust: galvanized rust delays significantly.
3. Create a sacrificial anode: The zinc coating is consumed by corrosive substances, so it provides protection for the underlying metal until it is completely used up. Even if the scratch penetrates the coating, the zinc will run out before the iron.
4. Durability: The zinc coating formed by galvanizing is tough and long-lasting, often providing decades of protection for the underlying metal.
5. Affordable: Galvanizing is a fairly simple and affordable procedure that provides significant benefits with minimal outlays.
6. Form a thick coating: Although not suitable for all applications, galvanizing produces a thicker coating than, say, electroplating.

Classification of Coatings

1. PE Pre-painted Galvanized Coils

PE polyester color coated board has good adhesion, rich color, a wide range of formability and outdoor durability, medium chemical resistance, and low cost. PE polyester color coated board advantage is mainly cost-effective, in a more friendly environment or recommends you use PE polyester color coated coil.

2. HDP Color Coated Coils

HDP high-weather-resistant color-coated coils offer excellent color retention, UV resistance, and outdoor durability, along with strong film adhesion and rich color. They are particularly suitable for harsh environments with strong UV rays, such as those on the plateau, and offer exceptional performance.

3. SMP PPGI Coils

SMP silicone-modified polyester color-coated roll film is highly hard, wear-resistant, and heat-resistant, with excellent outdoor durability and gloss retention. It is particularly suitable for high-temperature workshops such as steel mills and indoor temperature-variable environments.

4. PVDF Pre-painted Galvanized Coils

PVDF fluorocarbon color-coated sheet offers excellent color retention, UV and weather resistance, solvent resistance, easy molding, and stain resistance, but its color selection is limited and its cost is high. It is particularly suitable for the harsh environments of highly corrosive factories or the humid, salty atmosphere of the seaside.

Coating Types	Paint Film(μm）	Using Environment	Service Life
PE	10+5	Friendly environment	7-8 years
SMP	20+8	Areas of high UV light	10-12 years
HDP	23+8	High-temperature environment	15 years
PVDF	25+8	Strong corrosive environment	20 years

Service Life of Different PPGI Paintings

As shown in the table above, the lifespan of pre-coated coils depends on the substrate, environment, galvanizing layer, and coating type. In terms of weather resistance, the order is: PVDF > HDP > SMP > PE. PVDF is preferred for corrosive environments, while PE is an option for mild environments.

Project Transportation

Conclusion

Now 210 tons of color coated coils have been sent to Libya, and customers will receive the coils soon. Our products are sure to satisfy customers, and we welcome more Libyan customers to come to consult and buy our products. For Pre-painted galvanized coils, Wanzhi has 12 years of production and sales experience. Our color-coated coils have been sold to more than 120 countries and regions in the world.

In addition to PPGI coils, we can also produce PPGL Steel coils, corrugated sheets, and roofing sheets. If you have any needs, welcome to contact us.
