PPGI Coils
Pre-painted galvanized iron (PPGI) coils and sheets in a wide range of colors for roofing and cladding.
PPGI Coils and Pre-Painted Galvanized Steel Coils Supplier for the Middle East
PPGI (Pre-Painted Galvanized Iron) coils are high-strength galvanized steel coils coated with multiple layers of primer and top paint. Tianjin Sino East Steel Group manufactures PPGI coils, PPGL coils and pre-painted galvanized sheets for roofing manufacturers, façade contractors and distributors across the GCC - from Dubai and Abu Dhabi to Riyadh, Doha and Kuwait City. Our pre-painted coils are produced on continuous paint lines with strict film thickness control, colour consistency and UV-resistant topcoats developed for intense Gulf sunlight.
What Are PPGI Coils?
PPGI coils begin as hot-dip galvanized steel coils, which are cleaned, pre-treated with a chemical conversion coating, and then coated with a primer and a polyester, SMP or PVDF topcoat. The result is a steel product that combines the corrosion protection of zinc with the aesthetic appeal and durability of a paint system. Because the paint is applied before forming, PPGI coils are ideal for roll-forming processes used to manufacture roofing sheets, wall panels, sandwich panels and gutters.
In the GCC market, PPGI is one of the most widely used materials for metal roofing and cladding. It is chosen because it offers a long service life in coastal and desert environments, a wide range of RAL colours, and significant cost savings compared with field-painted or aluminium alternatives.
Standards and Specifications
Our PPGI products are manufactured to international standards including JIS G3321, ASTM A755/A755M, EN 10169 and ISO 3575. Popular products in this category include:
- PPGI Pre-Painted Galvanized Coils - polyester (PE) coated, the most economical option for roofing and cladding
- Red Color Coated PPGI Coil - high-visibility red for warehouse and agricultural roofing
- Pre-Painted Galvalume (Zincalume) Coil and Sheet - AZ150 aluminium-zinc substrate for maximum corrosion resistance
- PPGI Pre-Painted Steel Sheet 26 Gauge - 0.5 mm pre-painted sheet for roofing and fencing
- Pre-Painted Galvanized Coil (White / Red) - the two most requested colours in GCC roofing projects
- Red Color Coated Galvanized Sheet - pre-painted sheet, cut to length for direct installation
Available specifications:
- Substrate: hot-dip galvanized steel (GI) or galvalume (GL, AZ150/AZ200)
- Thickness: 0.15 mm - 1.2 mm (base metal)
- Width: 750 mm - 1250 mm
- Coating: PE (polyester), SMP (silicone modified polyester), HDP (high durability polyester), PVDF

Applications Across the GCC
Pre-painted steel coils serve a wide range of applications in the Middle East:
- Roofing sheets: corrugated and trapezoidal PPGI roofing sheets for industrial buildings, warehouses and workshops
- Sandwich panels: PUF and rock-wool insulated panels for cold storage and modular buildings
- Wall cladding: architectural cladding panels for commercial and residential buildings
- Fencing: PPGI fencing sheets and privacy screens for residential compounds
- Home appliances: washing machine and refrigerator casings for local assembly plants
- Agricultural buildings: poultry houses and storage sheds throughout Saudi Arabia and Oman
Why Buy PPGI Coils from Sino East Steel?
As a direct factory, Sino East Steel controls the entire production chain - from the base cold-rolled coil to the final paint line - which guarantees consistent colour, thickness and adhesion batch after batch. We have more than 18 years of experience exporting steel to the Middle East and produce 500,000 metric tons of steel products every year from our 65,000 m² Tianjin facility.
For the GCC market we specifically recommend high-durability topcoats with UV stabilizers, because the intense sunlight in the region can fade standard polyester coatings. Our technical team will advise on the correct topcoat system for your project location and expected service life. Every PPGI coil is supplied with an EN 10204 3.1 Mill Test Certificate and our factory is certified to ISO 9001, ensuring full traceability.
Shipping and Delivery
PPGI coils are packaged for export with plastic film wrapping, edge protection and pallet fixing to prevent damage during sea transport. We ship regularly to Jebel Ali and Khalifa Port (UAE), Dammam and Jeddah (Saudi Arabia), Hamad Port (Qatar), Shuwaikh (Kuwait) and Sohar (Oman). Standard production lead time is 15 to 25 days, and sea freight to the Gulf takes approximately 18 to 25 days.
Frequently Asked Questions
What is the difference between PPGI and PPGL coils?
PPGI uses a galvanized (zinc-coated) substrate, while PPGL uses a galvalume substrate coated with aluminium-zinc alloy. PPGL offers better corrosion resistance and heat reflectivity, making it the preferred choice for roofing in hot coastal climates, though it is slightly more expensive than PPGI.
Which PPGI coating is best for the UAE and Saudi Arabia climate?
For exterior roofing in the Gulf, we recommend HDP (high durability polyester) or PVDF topcoats with UV stabilizers. Standard polyester (PE) is suitable for interior applications or budget-sensitive projects with shorter service life expectations.
Can you match custom RAL colours?
Yes. We can produce PPGI coils in any RAL colour. Custom colours may require a minimum order quantity and a slightly longer production lead time for paint preparation.
Do you supply PPGI sheets cut to length?
Yes. We supply PPGI sheets cut to your specified lengths, which reduces waste and labour costs at your site.
What are the payment terms for PPGI coil orders?
Standard terms are 30% T/T deposit with 70% balance before shipment, or an irrevocable L/C at sight. For established distributors we can discuss more flexible terms.

Quality Control and Testing
All products are manufactured and tested under our ISO 9001:2015 certified quality management system. Our in-house laboratory performs chemical analysis, tensile testing, bend testing and dimensional inspection on every production batch, and each shipment is accompanied by an EN 10204 3.1 Mill Test Certificate (MTC). For project-critical orders, we can arrange third-party inspection by SGS, Bureau Veritas, TUV or Intertek at the buyer's request, with inspection reports included in the shipping document set.
Traceability is maintained from the original heat number to the finished product, which is essential for project approvals, quality audits and long-term warranty claims in the Gulf region. We encourage new buyers to request samples and test reports before placing bulk orders.
