How to Build With Grid Beam is a guide to a clever and flexible system of construction for a wide range of home-built projects, from storage units to work spaces to furniture, vehicles, and structures. The system relies on the use of â€œsticksâ€ or beams of square tube steel or aluminum or wood with holes placed at regular intervals along the length of each stick. Using lag bolts or other fasteners, these sticks can be assembled quickly and easily into structures that are quite robust and easily adapted and reconfigured. And when you are finished with a project, you simply disassemble the project and use the components for something else. By using adapters and add-ons, most of which can be found in hardware stores, industrial supply houses, or fabricated in even a modestly-equipped shop, the system can be expanded to encompass a staggering array of applications.
