China PPGI/PPGL Steel Coils Suppliers - Prepainted Galvanized/Aluzinc Steel Factory Products
Color Coated Steel Coil/Sheet (PPGI/PPGL)
Primers
Epoxy – Polyester (Chrome – Chrome Free); for excellent corrosion and inter-coat adhesion. The Back Coat of the PPGI/PPAZ strip is Generally Polyurethane(PU)-Compatible Epoxy coated in order to have adhesion in case the coils are used for insulated sandwich panel manufacturing.
Topcoats (R.M.P & SMP)
R.M.P (Regular Modified Polyester): The most widely-used coil coating with durable Polyester paint and heat dried. Applied to interior/exterior materials with no heavy drawings, offering variable colours, glosses, and economic feasibility. Displays superior workability, durability, and weather resistance. Matt and wrinkle effects can be added to the top finish.
S.M.P (Silicon Modified Polyester): A silicon resin modified Polyester paint coated and heat dried. Offers higher durability than Regular Polyester, making it suitable for coastal areas and industrial zones. 10-15 years limited warranty provided.
S.M.P (Silicon Modified Polyester): A silicon resin modified Polyester paint coated and heat dried. Offers higher durability than Regular Polyester, making it suitable for coastal areas and industrial zones. 10-15 years limited warranty provided.

Frequently Asked Questions (FAQ)
What types of base plates are used for PPGI/PPGL steel coils?
The common base plates used include Galvanized sheet, Galvalume sheet, Zinc-aluminum-magnesium, Aluminum-zinc-magnesium, and Aluminum-magnesium-manganese.
What is the difference between R.M.P and S.M.P coatings?
R.M.P (Regular Modified Polyester) is highly cost-effective and widely used for general indoor/outdoor design. S.M.P (Silicon Modified Polyester) is modified with silicon resin, offering higher durability, better weather resistance, and a longer warranty (10-15 years), making it ideal for coastal and industrial zones.
What coating structures are available for these steel coils?
The available coating structures include Double-Coating + Double-Baking, Triple-Coating + Triple-Baking + Monochrome Printing, and Color Printing + Hot Laminating + Embossing.
How long does the HDP Pro coating last in a common environment?
High corrosion resistance and weather resistance polyester (HDP Pro) has a coating thickness of ≥25 um and can last up to 20 years in common environments.
What are the standard sizes and weights of the steel coils?
The thickness ranges from 0.11mm to 1.5mm, the width ranges from 600mm to 1500mm, the internal diameter is 508/610mm, and the coil weight generally ranges from 3 to 7 Tons.
