CGCC RAL 5020 PPGI coil or PPGL coil for roofing, wall cladding and formed panels. Confirm the galvanized or aluminium-zinc substrate, paint system, dimensions, colour, forming route and packing per order.
This CGCC RAL 5020 PPGI or PPGL coil is a prepainted steel coil specification for roofing sheets, wall cladding and other formed building products. The buyer selects the metallic substrate first—galvanized steel for PPGI or aluminium-zinc coated steel for PPGL—then confirms the paint system, RAL 5020 colour, dimensions and forming route per order.
RAL 5020 gives the project a defined colour reference, while the coating schedule controls the finished surface. Confirm the primer, topcoat, back coat, gloss, surface treatment and any colour-retention requirement with the project specification. The colour name alone does not define the complete paint system. A sample review can help when appearance matters.
CGCC identifies the requested steel grade, but the final order still needs the governing standard, base-metal thickness, coating mass, width tolerance and forming requirement. Keep PPGI and PPGL separate in the quotation: their metallic substrates are different even when the colour and paint family are similar. State the substrate clearly so production and inspection follow the same material schedule. This also keeps colour approval tied to the correct steel system during production.

This prepainted coil suits roofing and cladding projects where colour, substrate and forming details must be agreed before production. Confirm the exposed face, profile, bend radius, storage route and receiving line before the coil is released for forming.
For related material selection, review the PPGI Coil range and the Galvanized Steel Coil range.
Send the roofing profile, drawing, bend geometry, exposed face, cut length, slit schedule and minimum bend requirement before production review. Confirm whether the order requires parent coil, slit coil or cut-to-length sheets. The paint system and surface protection must match the actual roll-forming and handling route. Identify the line direction and any surface-protection limits before approval. Share the receiving line details when the formed profile has tight tolerances.
Confirm coil weight, outer diameter, orientation, edge protection, moisture protection, strapping, shipping marks and container-loading limits per order. State the lifting and storage plan as well. Use the steel coil export packing guide when preparing the enquiry.
No. PPGI uses a galvanized steel substrate, while PPGL uses an aluminium-zinc coated steel substrate. Confirm the substrate before comparing quotations.
No. RAL 5020 identifies the colour reference. Primer, topcoat, back coat, gloss and performance requirements must be confirmed separately.
CGCC identifies the requested steel grade. Confirm the governing standard, thickness, coating, tolerances and forming requirements per order.
Yes, it can be reviewed for roll-formed roofing when the substrate, paint system, thickness, profile and bend requirements match the project.
Compare PE, HDP, SMP or PVDF against sunlight exposure, forming, appearance, maintenance and the project specification. Do not select by colour alone.
State thickness, width, tolerances, coil ID, coil OD, target weight, quantity and whether the buyer needs parent coil, slit coil or cut-to-length sheets.
