Box section member with light webs
Plywood in the webs spaces the flanges apart to form a rigid
and strong beam or post that is light and can be built to
almost any depth. The box beam can be straight, tapered or
formed to almost any shape. Nailing patterns are crucial to
load carrying capacity.

Box section member with heavy webs
Plywood or LVL in the webs spaces the flanges apart to form
a rigid and strong beam. Built to depths up to 1200, the
heavy flanges increase the load carry capacity. Nailing
patterns are crucial to the structural design.

Box section member: Double
Plywood in the webs spaces the flanges apart to form a rigid
and strong beam or post that is light and can be built to
almost any depth. Double sections have increased strength
and stiffness where depth is a major consideration.

Box section member: Triangular
Structurally, triangular beams perform similarly to
rectangular ones but they provide a wider range of
architectural options for walls or as pre-finished ceiling
and roof elements.

Folded plate
Similar to a series of triangular beams fixed next to each
other, the webs can be slotted into the flanges and fixed
with nails or staples. With good spanning qualities along
the folds, the plate can easily curve across the folds.
