China PPGI/PPGL Prepainted Galvanized/Aluzinc Steel Coils - Quality Suppliers & Factory Direct أسعار
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 Expoxy coated inorder to have adhesion in case the coils are used for insulated sandwich panel manufacturing.
Topcoats: R.M.P (Regular Modified Polyester)
Regular Modified Polyester is most widely-used coil coating with durable Polyester paint and heat dried. It is applied to interior/exterior materials with no heavy drawings. Thanks to its variable colours and glosses with an economic feasibility. RMP coated products are used for exterior panels and interior design purposes that do not require excessive processing. It generally displays superior workability, durability, and weather resistance and used for a variety of purposes; offered in a wide array of colours and degrees of polish.
Matt and wrinkle effect can be added to the top finish.
End Usage:
- Roofing & siding panels
- Interior Partition
- Building Interior/Exterior
- Sandwich panels
- Roof, Gutter
- Steel furniture
- Shutter, Door, Garage Door, Iron Frame, etc.
Topcoats: S.M.P (Silicon Modified Polyester)
Silicon Modified Polyester is a silicon resin modified Polyester paint coated and heat dried. Due to its higher durability than the Regular Polyester, generally applied for building construction. SMP assures economic benefits under circumstances of sea-side or industrial zones. 10-15 years limited warranty provided.
SMP products are coated and baked with paint containing silicon resin. It is suitable for coastal area due to its excellent weather resistance.
End Usage:
- Public Construction Material
- Sandwich Panel
- Corrugated Roof in Industrial Complexes
- Airport, etc.

Frequently Asked Questions (FAQ)
What types of primer are used for PPGI/PPGL coils?
We use Epoxy – Polyester (Chrome – Chrome Free) primers to achieve excellent corrosion resistance and inter-coat adhesion. The Back Coat is generally Polyurethane (PU)-Compatible Epoxy coated to ensure strong adhesion when used in insulated sandwich panel manufacturing.
What is the difference between R.M.P and S.M.P coatings?
R.M.P (Regular Modified Polyester) is the most widely-used economical coating, offering good workability, durability, and a wide array of colors. S.M.P (Silicon Modified Polyester) incorporates silicon resin, providing higher durability and better weather resistance, making it ideal for coastal areas and industrial zones with a 10-15 years warranty.
What base plates can be used for Color Coated Steel Coils?
We support a wide range of base plates including Galvanized sheet, Galvalume sheet, Zinc-aluminum-magnesium, Aluminum-zinc-magnesium, and Aluminum-magnesium-manganese.
What sizes and weight parameters do you offer?
Our color coated steel coils are available in thicknesses from 0.11mm to 1.5mm, and widths from 600mm to 1500mm. The standard internal diameter is 508/610mm, and the coil weight ranges from 3 to 7 tons.
Which coating type offers the longest service life?
High corrosion resistance and weather resistance polyester (HDP Pro) offers the longest service life of up to 20 years in common environments, followed by Fluorocarbon (PVDF) and Silicon Modified Polyester (SMP) which offer up to 15 years.
