The tree grate is made of solid cast-iron. Both the tree grate and the innerside of the tree grate are square of shape. The tree grate consists out of 4 segments. The framework consists of at least 2 segments. The tree grate is standardly suited to bear the load of pedestrians and cyclists. To increase the load-taking capacity, a light frame (for cars) or a heavy frame has to be installed underneath the tree grate. The segments of the tree grate can be assembled to each other with M12x60mm bolts. Optionally, a removable inner ring can be applied. Tree protection cages can be mounted if the tree grate is combined with a frame. The grate is standard black waxed. This layer is going to oxidate within some months, therefore the colour is getting darker.
