PPGI is a galvanized color-coated steel material. The coated steel sheet is subjected to surface chemical treatment, and then coating is applied and then baked. It has the mechanical strength and easy formability of steel plates, as well as the good decorative properties and corrosion resistance of organic materials. The coating has strong adhesion and can keep the color fresh for a long time. PPGI is widely used in various fields such as construction, home appliances, furniture, public facilities and transportation.
Product Parameters
Color Selection
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.

Galvanized color coated roof panels are widely used in commercial, agricultural, industrial and civil buildings. This is because it has many benefits, such:
Long Service Life
The color coated GI roof panel adopts galvanized steel sheet as the base material, which is durable. Several coatings are then applied to enhance its corrosion resistance. Therefore, the service life of PPGI roofing panels will exceed 15 years.
Noise Reduction And Heat Insulation
The profile design of the color galvanized roof can reduce the sound resonance and isolate the noise. In addition, due to its low thermal conductivity, it can help you keep your home cool on hot, sunny days.
Low Installation Cost
PPGI roof panels are lightweight and easy to transport and install. The use of color coated roof panels can shorten the construction period by 40%. In addition, the colored galvanized roof can be recycled, especially for mobile homes. It can reduce your construction costs.
Beautiful Appearance
Galvanized color coated roof panels are rich in color and unique in design, and can be used in a variety of styles. In addition, the painted roof looks great, which means that no surface decoration is required.
Good Drainage Performance
Galvanized color coated roof panel has waterproof function. In rainy areas, the corrugated design can help rainwater gather and run down quickly.
Excellent Safety Performance
PPGI plate retains the mechanical properties of the base metal, such as high tensile strength, great toughness and so on. Not only that, when made into a corrugated roof, it can bear more weight.
Scope of Application
Agricultural Applications: Including but not limited to greenhouses, chicken coops, stables, hay barns and barns
Residential Applications: Including residential houses, simple houses, apartments, towers, garages, storage sheds, etc.
Commercial Applications: For example, factories, warehouses, manufacturing plants, department stores, office buildings, etc.
Public Buildings: Such as cinemas, exhibition halls, gymnasiums, terminal buildings, schools, hospitals, etc.
Chemical Industry
steel is used to construct facilities such as large storage tanks, refining equipment, and chemical pipelines.
Natural Gas Industry
Steel is also widely used in the energy industry, such as oil and gas pipelines.
Oil Pipeline
In the oil and gas industry, carbon steel is used to manufacture various equipment and pipelines.
Ship
In shipbuilding, steel is used to manufacture key components such as ship structures and engine parts.
Stadium
Steel plays an important role in steel structure buildings such as high-rise buildings, large-span buildings, and sports venues.
Water Treatment
The application of steel in water treatment is mainly reflected in the construction of water treatment equipment and the production of components such as pipelines.
Q1: What metal materials do you supply?
Jiangsu Zhongersheng is a professional manufacturer mainly supplying carbon steel, hot-dip galvanized steel, PPGI color coated steel, 201/304/316 stainless steel sheets, coils, tubes and profiles, as well as various steel structural parts. Our products serve infrastructure, photovoltaic, machinery manufacturing, chemical and new energy industries.
Q2: Can you customize material grades, thickness and sizes?
Full customization is available. For carbon steel, galvanized steel and stainless steel, thickness, width and length can be adjusted in accordance with ASTM & EN standards. Profiles can be cut and processed as per drawings, and special steel materials can be customized via production line scheduling.
Q3: What’s the difference between galvanized steel and color coated PPGI?
Hot-dip galvanized steel features pure zinc anti-rust coating with cost-effective and wear-resistant performance, suitable for steel brackets, guardrails and load-bearing structures, and supports secondary painting. PPGI takes galvanized sheet as base material with colorful coating for anti-rust & decorative purposes, widely used for factory roof/wall panels and energy storage housings. Thick galvanized steel is recommended for rainy coastal areas, while PPGI is ideal for decorative outdoor projects.
Q4: Do you have spot inventory? What’s your MOQ?
We built a 10,000-ton standardized warehouse with abundant spot stock of carbon steel, galvanized steel and stainless steel. 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 of multiple steel types is supported.
Q5: How long is the delivery time for spot goods & customized goods?
Spot goods can be loaded within 3-7 days; simple cutting & bending processing orders take 7-10 days; mould opening & special steel customization takes 15-30 days, subject to specific specifications confirmation.
