Easy to maintain

The Multigard® is one of the only roller shutter doors that can achieve its SR rating without the need for a canopy. This means servicing access is fast and easy. It incorporates split guides allowing fast and efficient curtain repairs following collision damage. This also removes the need for working at height, increasing safety and reducing operational downtime. The door achieves Class 5 wind loading without the need for windlocks which traditionally can be a problem for attracting corrosion, as well as pinch points on the door’s operation.
