Shaped tree grilles
Shaped grilles
Well designed grilles enable the tree to receive natural water, prevent surrounding soil from being compacted and add architectural flair to the paved surface. Designs vary to function best under different circumstances. Fine mesh grilles are offered where minimum change to the surface is needed. They will retain planting material and mulches but allow the free passage of pushchairs, wheelchairs, supermarket and shopping trolleys.
Octagons and hexagons provide an interesting alternative to squares without introducing the need for curves. Their use can give some very striking combinations within the blockwork design. All are supplied complete with medium or heavy duty frames and anti-vandal bolts.

Continental grilles
Originally designed to integrate with very ornate, traditional French architecture, this range is particularly suitable where something a little different is required. Each grille is available in a single size only. The entire range is made in ductile (SG) iron as standard. The articulated jointing system, used with flexible medium duty frames allows the grilles to be used in occasional traffic areas.

topRaised tree grilles
Raised grilles are unusual in their effect in that they contain vertical elements and thus make very distictive features. The elevation can be used to display plaques etc. This range is manufactured in cast iron and requires a special medium duty frame giving extra support.

This grille design is excellent in a car park environment as it is sympathetic to both pedestrians and vehicles alike. The gentle curves allow vehicular overrun up to 6.5 tonnes SMWL when used with a CIS Street Furniture medium duty frame, or 11.5 tonnes SMWL when combined with a heavy duty frame. The 1061 is available in two sizes – 1000mm outside diameter (400 inside) and 1200mm outside diameter (460 Inside). |

This series of raised tree grilles are designed to be used with more mature trees. The large base aperture can accomodate sizes of tree up to 1000mm in diameter. Due to their convex design they are ideally used around trees with bulbous root systems. |
Removable inners
1091 |
|
Young trees need only a small grille aperture, especially if guards are not used. The soil close to the tree can be protected using inner sections which can be removed as the tree trunk grows. The inners illustrated here will fit all grilles with 600mm diameter apertures. |

Creating alternative patterns using standard grilles
Using both round and square versions of the same design these ‘D’ and tear drop shaped derivations are achieved. 1072 and 1077 combinations are illustrated but other designs possible include 1002 + 1022, 1003 + 1023 and 1007 + 1027.

CIS Street Furniture was chosen by Legoland (Windsor) to satisfy all of their tree protection requirements at the Legoland theme park. Various combinations of products were used based on the 1002/1022 grille design. Patterns formed include square, round and ‘D’ shaped. In some cases inners have been used to further protect young trees. Guard type 1180 was chosen along with a spherical finial type A to protect the tree trunk.
