Join is Green Theory’s modular system of planters, edging and planting trays. Constructed of highly durable aluminium or weathering steel, pieces easily bolt together to create an array of small or large configurations. Join system items are made to order, so size, colour, finish, accessories and detailing are customizable. Turnaround time is quick too—pricing is provided in minutes and approved orders are fulfilled in two to three weeks. To ensure the whole process runs smoothly, we manage projects in-house from start to finish.
