PrimeAlux supplies prepainted steel coil, known in the market as PPGI, on the same coating line as our coated aluminum. The same coating systems, color matching and quality checks apply to both metals. Sourcing both from one supplier simplifies color matching, qualification and logistics. The coil is manufactured by our partner mill.
PPGI means prepainted galvanized iron, the common name for prepainted steel coil on a galvanized substrate. Gauge, width, tolerances, grade and order size are confirmed per project.
| Substrates | Steel and aluminum (same coating line) |
|---|---|
| Coating systems | PE, HDPE, PVDF, PU, PUPA, Epoxy, Acrylic, Epoxy-PE |
| Color | Any RAL or custom match |
| Coating sides | One-side, or two-side with primer |
| Finishes | Solid, metallic, woodgrain, brushed, matte / gloss, textured |
| Gauge, width, tolerances | Available on request |
| Temper / grade | Available on request |
| Minimum order | Confirmed per project |
Both coat and form well, and we supply both. The decision usually comes down to corrosion, weight, stiffness and cost.
| Property | Coated aluminum | Coated steel (PPGI) |
|---|---|---|
| Corrosion | Does not rust | Protected by the coating over a galvanized substrate and pretreatment |
| Weight | About a third the weight of steel | Heavier than aluminum |
| Stiffness and strength | Lighter, lower stiffness per unit thickness | Higher stiffness and strength per unit thickness |
| Material cost | Typically higher | Typically lower |
| Forming | Forms easily | Forms well with proper coating and pretreatment |
| Favored when | Weight and corrosion resistance lead: roofing, gutters, facades, transportation | Rigidity and cost lead the decision |
The same coating systems and color matching run across steel and aluminum, so a roof and its trim can match even when they use different metals.
Both metals are coated on the same line and tested against the same ASTM or EN references, which simplifies qualification.
Combining coated steel and coated aluminum on one supply relationship reduces the number of vendors to manage.
Manufactured by our partner mill at a plant certified to ISO 9001, ISO 14001 and ISO 45001.
Coated steel is tested against ASTM or EN references, including salt spray, UV, T-bend, adhesion, gloss retention and color difference (delta E).
Material certificates accompany every batch. Test reports are available on request.
Yes. PPGI, short for pre-painted galvanized iron, is the common market name for prepainted steel coil on a galvanized substrate. It is the product on this page.
Yes. Both metals are coated on the same line with the same coating systems and color matching, so colors can be matched across a project that uses both.
The same families as coated aluminum: PE, HDPE, PVDF, PU, PUPA, Epoxy, Acrylic and Epoxy-PE. The system is chosen for the exposure and forming the part needs.
