Paint systems and coating structure
| Item | Specification options |
|---|---|
| Substrate | Galvanized steel for PPGI; aluminium-zinc coated steel for PPGL |
| Primer | Epoxy, polyester, polyurethane or specified compatible primer |
| Topcoat resin | PE / SMP / HDP / PVDF, selected by exposure and forming |
| Topcoat thickness | 10–30 µm for coil reference range |
| Reverse coating | 5–25 µm for coil reference range |
| Color | RAL code or approved physical sample |
| Appearance | Gloss, texture, print pattern and protective film to approval |
| Testing | Dry film thickness, adhesion, T-bend, gloss and color difference as ordered |
Resin names do not define base-steel chemistry or a universal service-life guarantee.
Zinc coating designations
| Designation | Minimum total mass, both sides (g/m²) | Basis |
|---|---|---|
| Z100 | 100 | Three-spot test |
| Z120 | 120 | Three-spot test |
| Z140 | 140 | Three-spot test |
| Z180 | 180 | Three-spot test |
| Z200 | 200 | Three-spot test |
| Z225 | 225 | Three-spot test |
| Z275 | 275 | Three-spot test |
Coating mass is separate from base-steel grade; Z275 is not a strength grade. Do not treat ASTM G90 and EN Z275 as identical acceptance specifications.
Coating order specification
| Item | Selection |
|---|---|
| Primer options | Epoxy, polyester, water-soluble acrylic or polyurethane |
| Color specification | RAL reference or approved color sample |
| Steel substrate | Select base-steel grade independently of the paint resin |
| Coating layers | Specify metallic coating, primer, topcoat and reverse coating separately |
Coating test results and exposure guarantees depend on the selected paint system and order; no universal salt-spray life is implied.
Grade-specific technical data
Select a grade to view its composition, mechanical properties and applicable test conditions.
DX51D+Z substrate option
Steel substrate: DX51D+Z — chemical composition
| Element | Maximum / range (% by mass) |
|---|---|
| C | ≤0.180 |
| Mn | ≤1.20 |
| P | ≤0.120 |
| S | ≤0.045 |
| Si | ≤0.50 |
| Ti | ≤0.300 |
Heat analysis limits; the ordered standard edition and grade take precedence. Applies only when this substrate grade is ordered; the organic coating does not define the steel strength.
Steel substrate: DX51D+Z — mechanical properties
| Thickness (mm) | Tensile strength Rm (MPa) | Elongation A80 min. (%) |
|---|---|---|
| 0.20–0.35 | 270–500 | 15 |

Frequently asked questions
What should I include in my enquiry?
Send the product, grade or standard, dimensions, quantity, required finish and destination. Describe the end use if the specification is still being developed.
Can I request a particular size or finish?
Yes, include your required size and finish in the enquiry. Availability and any processing requirements must be confirmed in the quotation.
How are minimum order and lead time confirmed?
They depend on grade, dimensions, processing and quantity. We confirm them for the particular order rather than publish one figure for every product.
What documents should I request?
State the material test document, inspection scope and other purchasing documents required for your project. Agree these with the order.
