Magnetic holding pads are designed for securing items to receptive surfaces. They are used extensively for securing roof signs to vehicles and signs to steelwork and internal metal structures.
They work by exerting a combination of high magnetic strength and friction, giving an immense resistance to shear forces when mounted to smooth steelwork.
The magnetic base that is in contact with the metal surface has a polyurethane coating that is relatively soft to prevent scratching. The back plates of the magnets are coated to prevent corrosion and come with the design options of holes or thread studs for fixing.
