Paver-Grate® Pavement Suspension System

IRONSMITH’s Paver-Grate® Pavement Suspension System lets you design over (instead of around) tree plantings for optimized planting space, tree health and pedestrian comfort. Paver-Grates® provide a way to create visually seamless expanses of unit pavers in plazas, malls and building entries while incorporating trees for shade and scale. It is a very flexible system that can be used alone or in combination with traditional tree grates to increase the uncompacted root zone.

Tree Guards

IRONSMITH tree guards are crafted from heavy steel to hold up in the most vigorous urban environments. Besides offering protection from bicycles, carriages and car doors, they also add vertical interest in your pedestrian space, enhancing either a contemporary look or a historical period style.


Adding security while keeping the design theme cohesive is no longer a challenge with IRONSMITH bollards and caps. Installation options include both permanent and removable configurations.
