◉ Product Description
The coating was aluminized zinc steel made of 55% aluminum, 43.3% zinc and 1.6% silicon. Aluminum forms a honeycomb layer around the zinc, which can protect the metal from further attack. This means that PPGL will be more durable. According to the data, the service life of PPGL roof panels under normal circumstances is more than 25 years. In addition, it is beautiful and generous, with various colors, patterns and patterns, which can meet different architectural styles. More importantly, PPGL steel has excellent heat resistance, which makes it an ideal roofing material even in hot climates. Whether it is home or investment, PPGL roof panels will be a good choice.
We provide many colors to choose from, the following are common colors, if you like other colors or patterns, please send us the RAL color code.

PPGL is short for pre-coated aluminum-zinc steel, which uses aluminum-zinc steel as the base material. It is widely used in many fields, especially in roof and wall systems.
High Corrosion Resistance
The coating was aluminized zinc steel made of 55% aluminum, 43.3% zinc and 1.6% silicon. Aluminum will form a honeycomb layer around the zinc, which can protect the metal from further attack. This means that PPGL will be more durable. According to the data, the service life of PPGL roof panels under normal circumstances is more than 25 years.
Excellent Heat Resistance
Galvanized zinc steel has good heat resistance and can withstand high temperatures above 300 degrees. In addition, it also has the characteristics of high thermal reflectivity. It can therefore even be used as an insulating material. This is why PPGL is a good choice for roofing materials.
Easy Installation And Maintenance
The weight of the PPGL sheet is much lighter than conventional materials. It can also be used directly. All you need to do is connect the roof slabs. As a roof, it is very easy to install to reduce construction time and cost. In addition, it is made of high-strength steel, which is enough to withstand extreme weather. No matter where you are, PPGL will be a cost-effective solution for your roof.
Beautiful Appearance
The aluminized zinc steel plate has good adhesion and smooth surface. Moreover, it can keep the color for a long time. Not only that, Wanzhi Steel also provides a variety of finishes and designs of PPGL corrugated board to choose from, which can adapt to different architectural styles. So no matter what color you want, glossy or matte, dark or light, please contact us for more details.

◉ FAQ
Q1:What metal materials do you supply?
A:We supply one-stop full range of metal materials: pure copper & brass, carbon steel, hot-dip galvanized steel, PPGI/PPGL color coated steel, 201/304/316 stainless steel, high temperature alloy, industrial aluminum profiles and various structural profiles. Sheets, coils, tubes, bars are all available for infrastructure, new energy, machinery, chemical and electrical industries.
Q2:Can you customize material grades, thickness and sizes?
A:Customization is available. For stainless steel, copper, aluminum, galvanized & color coated steel, thickness, width and length can be adjusted per ASTM & EN standards. Profiles can be cut to fixed length or custom moulded according to drawings. Special alloy materials can be ordered from steel mills.
Q3:What’s the difference between galvanized steel and color coated PPGI?
A:Galvanized steel only has zinc coating for basic anti-rust with lower cost, suitable for brackets, guardrails and load-bearing structures. PPGI is galvanized base with colored paint layer, anti-rust & decorative, widely used for factory roof/wall panels and equipment housings. Thick galvanized steel for rainy coastal areas, PPGI for decorative outdoor projects.
Q4:Do you have spot inventory? What’s your MOQ?
A:We own 10,000 tons standardized warehouse with spot carbon steel, stainless steel, galvanized, copper and aluminum materials. MOQ is 1 ton for standard sizes; small samples of dozens of kilograms are acceptable. No upper limit for bulk engineering orders, mixed container loading with multiple metals is supported.
Q5:How long is the delivery time for spot goods & customized goods?
A:Spot goods can be loaded within 3-7 days; simple cutting processing orders take 7-10 days; mould opening & special alloy customization takes 15-30 days, subject to specific specifications.
