Our 20mm Ball Proof Grating is designed to be used where the working platform or walkway is above a place where people are working (as opposed to people passing under it occasionally).
The 20mm Ball Proof Grating’s maximum openings shall not permit the passage of a 20mm diameter sphere.
It is typically used on walkways above machinery and permanent working areas, where the risk to personal from large objects falling from above is critical.
Our 20mm Ball Proof Grating complies to Specification to: BS45920:2006+A1:2012.
