The GT Resi-Grille System is a cutting-edge solution developed in direct response to contractor demand across the UK for a tree grille that combines strength, visual appeal, and sustainable surface design. Engineered to integrate seamlessly with GT Resibond, the system features a recessed 50mm depth, allowing the grille to be filled with porous GT Resibond material. This not only supports the load of street and pedestrian traffic but also protects the tree’s root ball and promotes healthy tree growth in urban settings.
 
Designed specifically for high-footfall public realm projects, streetscapes, civic schemes, and regeneration initiatives, the GT Resi-Grille delivers a durable and contemporary finish. Once infilled, it creates a solid yet porous surface that minimises soil compaction, reduces trip hazards, and eliminates the accumulation of litter, cigarette ends, and debris commonly seen with traditional tree grille systems.
 
Manufactured from hot dip galvanised mild steel, the Resi-Grille is built to BS EN ISO 1461:1999 standards, offering long-term resistance to corrosion, wear, and harsh weather conditions. It’s an ideal choice for landscape architects, urban designers, councils, and engineers seeking to enhance urban greening schemes while meeting accessibility and durability requirements.
