Whiteboard Writing Steel Coil

Whiteboard writing steel coil is the painted surface material that a magnetic whiteboard is built from.

Product Overview

What This Board Is

Whiteboard writing steel coil is the painted surface material that a magnetic whiteboard is built from. Senko coats the steel in its own coil line and sells it by the coil to board manufacturers who laminate it onto their own cores and frames. Because the magnetism comes from the steel itself and the writing performance from the paint, the coil decides how the finished board will write, erase and hold magnets years after it leaves your line.

Key Benefits
  • Smooth painted face writes and erases cleanly so finished boards do not ghost after repeated use
  • Steel substrate keeps the board magnetic without a separate magnetic layer in the build
  • Three surface types from one supplier so one purchase order covers plain office boards projection boards and squared boards
  • Coil form feeds straight into a laminating line with no sheet by sheet handling

Quality Control

Checked Before Packing

  • Writing and erasing checked on the painted face before the coil is released
  • Colour and gloss compared across the coil so boards cut from one order match each other
  • Thickness confirmed against the ordered gauge inside the 0.16 to 0.6mm range
Customization Options

What Can Change

  • Choice of glossy plain grid or matt projection surface
  • Thickness selected anywhere in the 0.16 to 0.6mm range
  • Grid pitch supplied as the standard 5x5cm layout
Use Guide

Getting It Right On Site

  • Laminate the coil face up onto a flat core such as MDF corrugated cardboard or honeycomb sheet
  • Pair the coil with a galvanized steel backing sheet so the panel does not bow
  • Keep the protective film on until the frame and corners are fitted
Comparison

How It Differs From The Alternatives

Compared with Melamine MDF writing sheet

Melamine writes at a lower cost but is not magnetic; painted steel coil gives a magnetic face.

Compared with Finished imported whiteboards

Importing coil ships far more writing area per container than importing assembled boards.

Questions

Whiteboard Writing Steel Coil FAQ

What thickness should I order for classroom boards?

Thicker gauges in the 0.16 to 0.6mm range are normally chosen for large classroom boards and the thinner end for small office boards. Send us the board size and we will advise.

Which paint do you use?

The coils are painted with KCC and NIPPON paint systems.

Can I get a grid surface?

Yes. White surface with a 5x5cm grid is a standard surface type alongside high glossy plain white and matt projection.

Is the coil magnetic?

The steel substrate is magnetic, which is what makes the finished whiteboard hold magnets.

Can I have a sample before ordering a coil?

Yes, we supply samples. The freight cost is discussed case by case.

What is the lead time?

Around 30 days for one 40'HQ container. Send your quantity and we will confirm for your order.
