PRODUCT BRIEF

The product of a collaboration with Peter Walker and Partners for use in their award winning Jamison Square, the aptly named Jamison design has been adopted by the design community as the new standard for a high quality, modern, pedestrian friendly tree grate.

Its clean modern rectilinear design of 1/4″ openings offset by 3/8″ bars seems simple, but belies the deep technical expertise needed to successfully cast this product.

Further, the products modular nature has produced some unique applications – continuously grated multi-tree planting areas, walkway decking and more.
