Grid Beam Guide


Guide

Grid Beam is a simple technique to build things from re-usable parts.
In the Grid Beam system, there are 5 types of parts:
  • beams (wood, aluminum, or steel)
  • nuts and bolts
  • skins (plywood, sheet metal, or fabric)
  • accessories (wheels, lights, sinks, drawers, etc)
  • adapters, which let you bolt odd-size accessories into the system

Quickstart

The key to Grid Beam's quick assembly and strong integrity is the tri-joint:when 3 beams join together with 3 bolts, they form a strong bond.
To see how this works in action, let's construct a simple work bench!

Beams

Beams are square sticks, where the width is the same on both sides.
Each beam has a repeating hole pattern wherethe distance between each hole is equal to the width of the beam.The hole pattern is the key to Grid Beam's modularity and interoperability.
Beams can be made from either wood, aluminum, or steel.

Nuts and Bolts

The nuts and bolts are the fasteners that connect the beams together in the strong tri-joints.

Skins

Skins are the flat planels that go over the beams.

Sizes

Grid Beam thrives with standard sizes.
