PPGI Coils
PPGI Coils Manufacturer and Supplier in Indonesia
PPGI (pre-painted galvanized iron) coils are galvanized steel coils coated with primer and a top coat of paint, combining corrosion protection with a durable decorative finish. Sino East Steel is a ppgi coils manufacturer and supplier based in Tianjin, China, exporting to Indonesia and more than 50 countries for over 18 years. As a direct factory supplier with a 65,000 m2 production base and 500,000 tons of annual capacity, we deliver to Indonesian importers, distributors, contractors and project companies with complete documentation, including the Mill Test Certificate (MTC) per EN 10204 3.1 on every shipment.
Indonesian buyers choose our ppgi coils because every batch is tested in our ISO 9001:2015 certified quality system, packed seaworthy and shipped to Tanjung Priok (Jakarta), Tanjung Perak (Surabaya), Belawan (Medan) and Makassar within 18-25 days after production. Third-party inspection by SGS, BV or TUV can be arranged at the factory or at the destination port, and SNI documentation support is available for regulated applications.
What Is PPGI Coils?
PPGI coils are produced by applying a multi-layer paint system to hot-dip galvanized steel: chemical pretreatment, primer, and a top coat selected from polyester (PE), silicon-modified polyester (SMP), high-durability polyester (HDP) or PVDF fluoropolymer. The result is a pre-finished material that needs no painting on site, available in any RAL color, with gloss levels and special effects such as wood print, stone print and embossed finishes.
Indonesian roof sheet rollers, building material traders and appliance manufacturers buy PPGI coils from Sino East Steel for residential roofing, commercial cladding, wall panels and metal furniture, with stable color consistency from coil to coil and full MTC documentation on every shipment.

Coating Performance and Color Consistency
The paint system determines how long a PPGI roof keeps its color in Indonesia's tropical UV environment. We control coating thickness (typically 20-25 microns total for PE, 25-35 for HDP/PVDF), hardness, adhesion and reverse impact strength on every batch, and we match color within Delta E tolerances across production runs. For coastal areas and premium projects we recommend HDP or PVDF coatings, which significantly outperform standard PE under intense UV and salt exposure.
Applications of PPGI Coils in Indonesia

- Industrial roofing - Factory and warehouse roofs with high UV resistance.
