Magnetic Signage

The steel panel facing of the our systems provides a natural surface for incorporating magnetic accessories for hanging pictures, coats, fire extinguishers, notice boards etc. With a magnetic backing, hooks, wall plates and signs can all be installed without drilling into the finished panel surface, keeping the wall finish untouched.  Accessories can also be relocated at any time by anyone (no maintenance required).
