Forgebar Grating 60 series
SERIES 60 GRATING - 60mm centres
Developed for the mining industry, series 60 grating has larger openings. This allows most materials to fall through and minimises build-up of spillage on platform floors, making for a safer walking surface. However, being very light, this profile of grating is not suitable for high impact loads. It has only 50% of the load bearing capacity of Series 30 grating.
