Product Description
PPGL Steel Sheet Description
PPGL is GL steel sheets coated with a colored paint layer.
Characteristics: PPGL provides enhanced corrosion resistance along with a wide range of color choices. It is suitable for architectural and industrial applications in harsh weather conditions.
Uses: Frequently used in the production of roofing, wall cladding, oil tanks, refrigeration equipment, and more.
PPGL stands for pre-painted galvalume steel, which is a kind of color-coated steel with GL as substrate. It combines the strength of steel with excellent anti-corrosion of Zn-Al coating. The galvalume coating is made of 55% aluminum, 43.4% zinc, and 1.6% silicon. Except for their excellent corrosion resistance, PPGL sheets also have high thermal reflectivity, which makes them heat-resisting.
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.
Advantages of Color Coated Plate
Custom Colors
You can choose any RAL color, as well as customize the pattern according to your needs. The beautiful surface makes the color coated board decorative. So it can be directly used in many fields.
Tough Soating
Color coated steel plate including PPGL plate PPGI steel, the use of continuous coil coating, the surface luster bright, no cracking, no peeling. In addition, it can keep the color for at least 10 years.
Excellent Mechanical Properties
The color coated plate retains the mechanical properties of the base metal, such as tensile strength. In addition, the application of the coating can protect the surface from rust, thereby extending its service life. Studies have shown that the service life of color-coated steel sheets is 50% longer than that of galvanized steel sheets.
Easy to Use
Different from the coil, the color coated plate is a kind of finished product. This means that it can be directly used in many industries. Considering its light weight, it is easy to carry and install. In addition, due to its aesthetic appearance, no additional decoration is required. Also, less maintenance is required during the service life.
Coating Type
In the coil coating, the durability of the role is the resin and pigment, the most commonly used finish polyester, silicon modified polyester, high durability polyester and polyvinylidene fluoride.
Polyester PE
Good adhesion, rich color, wide range in formability and outdoor durability, medium chemical resistance, low cost.
Silicon Modified Polyester SMP
The hardness, abrasion resistance and heat resistance of the coating film are good; as well as good external durability and powder resistance, gloss retention, general flexibility and medium cost.
High Durability Polyester HDP
Excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, good film adhesion, rich color, excellent cost performance.
Polyvinylidene Fluoride PVDF
Excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, excellent solvent resistance, good formability, dirt resistance, limited color, and high cost.

FAQ
Q1: What types of steel products does your company primarily manufacture and supply?
A: We are a direct manufacturer specializing in carbon steel, hot-dip galvanized steel, PPGI (pre-painted galvanized iron), and stainless steel (grades 201, 304, and 316) in the form of sheets, coils, pipes, and various structural profiles, along with complementary steel structural components. Our products serve a wide range of industries, including infrastructure, photovoltaics, machinery manufacturing, chemicals, and new energy.
Q2: Do you support customization regarding material grades, thicknesses, and dimensions?
A: Customization is available across our entire product range. For carbon steel, galvanized steel, and stainless steel, we can adjust thickness, width, and cut-to-length dimensions according to GB, ASTM, or EN standards. Various profiles can be cut and bent based on customer drawings, and special steel grades can be produced through customized scheduling.
Q3: What is the difference between galvanized steel and color-coated (PPGI) steel, and how should I choose for my project?
A: Hot-dip galvanized steel features a pure zinc anti-rust layer; it is cost-effective and impact-resistant, making it ideal for mounting brackets, guardrails, and load-bearing factory structures (and it can be painted over). PPGI color-coated steel uses a galvanized base, offering both rust protection and aesthetic appeal with a wide range of colors; it is commonly used for factory roofing, wall cladding, and energy storage equipment casings. We recommend thicker galvanized coatings for projects in rainy coastal areas, color-coated sheets for outdoor projects requiring visual appeal, and weather-resistant fluorocarbon (PVDF) coatings for high-temperature desert environments.
Q4: Does the factory keep stock on hand, and what is the minimum order quantity (MOQ)?
A: We operate our own standardized, zoned warehouse with a capacity of over 10,000 tons, maintaining ample stock of carbon steel, galvanized steel, and stainless steel. The MOQ for standard specifications is 1 ton, though we also accept sample orders as small as a few dozen kilograms. There is no upper limit for large-scale projects, and we support mixed-load shipments combining different steel products in a single container.
Q5: What are the lead times for stock items versus customized products?
A: Standard stock items take 3–7 days for processing, packaging, and container loading. Simple cutting and bending orders take 7–10 days. Orders requiring mold creation or special steel customization take 15–30 days; exact delivery dates are confirmed based on the customer's specific order specifications.
