QuartzGrip GRP Grating Joining Bars (also referred to as strengthening bars) enable you to join mesh panels side by side with minimal deflection between the two. Provides a smooth finish on large platforms or floors where panels need to join between support profiles. Secure using GRP M-Clips on open mesh grating and Dome Washers on solid top panels. We stock standard and mini-mesh versions of both. Where flexing isn’t likely to be an issue (on smaller spans) you can opt to use G-Clamps which will also keep panels tied together.
