Super-Light

Super-light TM is a new magnetic material offering greater power to weight ratio than the industry average standard 0.85mm magnetic sheet. At 0.5mm thick, Super-light TM has a pull force of 40g/cm2, but weighs 30% less than 0.85mm magnetic sheet.
The fact that Super-Light TM is a lighter material means that it is both cheaper to ship and once in your possession easier to handle. Due to its thickness and weight, Super-light TM covers vehicle surfaces more evenly, making it an ideal material for vehicle signs.
Supplied in 0.6mm x 620mm x 30metres.
