PPGL Steel is a composite building material made of aluminum-zinc coated steel as the substrate, with the surface chemically treated and coated. It has excellent corrosion resistance, heat resistance, and the rich decorative properties of color-coated steel sheets, long service life and high cost performance. It is used to build roofs, exterior walls, home appliances and factories. Wanzhi Steel is a professional supplier of PPGL coils and sheets in China, providing perforation, special-shaped, striping and other mechanical processing, supporting a variety of surface treatments such as matte, wrinkle, orange peel, texture, etc. We stock a variety of colors and thicknesses, support RAL color card full color customization and width customization. You are welcome to contact us for more information

Because of the 55% Aluminum, the corrosion resistance of PPGL is much better than PPGI, making the user life longer.
High heat resistance makes the building structure cool in hot summer.
PPGL Roof Sheet Production

Aluminum-zinc alloy steel can bear severe weather conditions, such as extremely hot Summer, cold winter, or rain.
Prepainted aluminum-zinc plating is easy to deform, such as cutting, profiling, etc.
PPGL looks attractive and impressive and is finished with a pleasant surface and aesthetics.
The color is generally divided into gray-white, sea blue, brick red, etc. If you like other colors, please send us RAL color codes or samples, and we will design according to your requirements.
PPGL Structure
RAL Color
The galvanized steel plate is covered with aluminum-zinc alloy on the surface of the steel plate. It is composed of 55% aluminum, 43.4% zinc, and 1.6% silicon solidified at a high temperature of 600℃. The entire structure is composed of aluminum-iron-silicon-zinc, forming a dense alloy-coated steel plate of a quaternary crystal. PPGL (pre-painted galvalume steel coils, pre-painted galvalume steel sheets) are widely used in roofs, side walls, electrical cabinets, agriculture, vending machines, home appliances, automobiles, color-coated substrates, etc.

The main factors affecting the price of color-coated steel sheets are the thickness of raw materials (substrate) and zinc layer, coating thickness, coating grade, steel coil thickness, and packaging methods.
The thinner the steel coil, the more expensive the price, because the thinner the steel coil, the more meters per ton of steel coil, the larger the area, and the more paint coating and longer color coating time will be used.
The price depends on the different thicknesses of the zinc layer. For example, the price of 20 grams of zinc coating and 50 grams of zinc coating is very different. If it is used in a humid, outdoor, and perennial tropical climate environment, it is recommended to choose a color coating with a higher aluminum and zinc content.
There are two types of color-coated steel coils: single-side color coating and double-side color coating.
Under normal circumstances, the thickness of the single-sided color-coated top paint film is 11-20μm, and the thickness of the back paint is 5-10μm. The thickness of the top coat of double-paint color coating is 11-30μm, and the thickness of the back paint is also 11-20μm. The price of single-sided color coating is lower than that of double-layer color coating. Customers need to choose the appropriate color coating according to the application and environment.
The price of color-coated steel coils is influenced by coating type and brand. Common coatings include PE polyester, PVDF fluorocarbon, HDP high weatherability, and SMP silicone-modified polyester. PE is the most widely used due to its high cost-effectiveness; PVDF, HDP, and SMP offer longer lifespans but come at a higher price. Renowned brands like Nippon Paint and AkzoNobel deliver superior performance. Customers should select appropriate coating types and brands based on their specific application environments and requirements.
Color-coated steel coil packaging is divided into simple packaging, standard export packaging, and special packaging. Simple packaging is suitable for short-distance transportation and uses waterproof kraft paper as the outer layer, providing simple protection and low cost. Standard export packaging, with waterproof kraft paper and galvanized iron sheet as the outer layer, is suitable for long-distance and container transportation. It is reinforced with steel wire for better surface protection and waterproofing, and is currently the most widely used packaging method.
