Quality And Production
How the coil is built and what is stated about its control.
The Coating Line In Sequence
Colour, pattern and protection are applied before the coil leaves the plant.
Coating Build Up For PCM Steel
Nine layers, published in full so a specification can be checked line by line.
| Layer | Type | Function |
|---|---|---|
| Protection Film | Polyethylene | Protects the paintwork from scratching and contamination |
| Clear Varnish | PE / SMP / HDP / PVDF | Transparent layer protects the printed layer and improves surface appearance |
| PVDF ink, PE | Carries the pattern, three colour printing | |
| Top Coating | PE / SMP / HDP / PVDF | Gives colour and appearance and forms a barrier film for long term durability |
| Primer | Polyester | Prevents undercutting of the paint and improves corrosion resistance |
| Chemical Treatment | Cr-free passivation | Pre-treatment layer for paint adhesion and corrosion resistance |
| Base Steel | GI, GL, EG, CR, AL | Galvanized steel, aluzinc steel, electro-galvanized steel, cold rolled steel or aluminium sheet |
| Chemical Treatment | Cr-free passivation | Adhesion and corrosion resistance on the reverse side |
| Backing Coating | Epoxy resin | Improves corrosion resistance and adhesion to the substrate |
Quality Statement
Senko Steel states that an international standard QC management system is applied to this production, so that output is in line with high end domestic and international manufacturing standards.
What Is Fixed Before Production
- Product and surface grade
- Thickness within the published range
- Coil width, inner diameter and coil weight
- Colour or pattern and the face style, plain or gridded
- Packing, marking and the documents required at destination
On certificates. No certification claim is published on this site. Ask for the specific document you need and it will be confirmed for your order rather than promised in advance.

Frequently Asked Questions
What quality system is applied?
Senko Steel states that an international standard QC management system is applied to this production, so that output is in line with high end domestic and international manufacturing standards.
Which certificates can you issue?
Document requirements differ by destination and by customer. Tell us what your import clearance and your own quality system need and we will confirm what can be issued for your order before you place it.
What protects the surface after production?
On PCM steel a polyethylene protection film covers the paintwork so it is not scratched or contaminated before installation.
What is checked on a writing surface?
Writing and erasing performance is what the product is specified on: it writes smoothly, erases cleanly and leaves no ghosting after erasing.
