Choosing Engineered Beams - Images 1-6

Use manufactured timbers to handle heavy loads and long spans

Laminated veneer lumber (LVL), like this structural ridge beam, is stronger than comparably sized sawn lumber because any natural defects like knots and splits are only one ply deep.

Dense southern pine LVL calls for a higher pressure setting on your nail gun. Even then, you may have to pound the heads flush.

Drill-point hex-head SDS screws from Simpson eliminate nail frustrations and provide a strong, warp-resisting connection.

Glulam lumber is manufactured in two grades for residential use. This is framing grade lumber.

Framing grade and architectural grade (shown) differ only in their appearance; there's no difference in their fabrication or strength.
