Cast Iron Tree Grille for Urban Tree Protection
The Cast Iron Sunburst Tree Grille provides a robust and visually striking solution for protecting tree pits in public realm settings. Its radial “sunburst” design allows water, air, and nutrients to reach the soil while preventing surface compaction caused by pedestrian traffic.
Commonly specified for streets, plazas, and landscaped civic areas, this tree grille helps maintain tree health while delivering a durable, long-term surface finish.
Heavy-Duty Cast Iron Construction
Manufactured from solid cast iron, the Sunburst Tree Grille is engineered to withstand heavy footfall and challenging outdoor conditions. Supplied in black as standard for express availability, it offers excellent durability and a timeless appearance suited to both contemporary and traditional schemes.
The grille sits securely within a supporting frame, ensuring long-term stability and resistance to movement once installed.
Designed to Support Healthy Tree Growth
By covering the tree pit while leaving an open central aperture, the grille helps reduce soil erosion and compaction. This encourages better root development and improves long-term tree performance in hard-landscaped environments.
Installation and fixing
Frames are available in medium or heavy-duty formats, depending on the level of central support required. The frame is fixed into a concrete surround either by bolting or by embedding tangs into wet concrete. Anti-theft clamps secure the grille to the frame once installed.
Typical installation guidance:
Concrete base approximately 150mm wide and 200mm deep
Frame fixed prior to grille installation
