Timberlab's CNC machines are equipped to handle 60ft sizes for both glulam and cross-laminated timber members. We work with suppliers from around the globe to fabricate material into a specialized, high-quality kit of parts ready for delivery.

Columns:
Glulam columns, either square or rectangular in cross-section, are subjected to stresses primarily in axial tension or compression and are most effectively manufactured with lumber of uniform grade. While we can produce glulam with many different grades of lumber, higher-strength lumber intended to reduce the cross-sectional dimensions of the member will have a higher cost and may be subject to longer lead times to gather wood of this grade.


Unbalanced Beams
Unbalanced beams are intended for use in simple-span applications loaded in positive bending, producing the greatest tension stress on the bottom of the beam. To resist such stresses, unbalanced beams are manufactured with the highest-strength laminations on the bottom of the member. Importantly, the asymmetry of unbalanced beams results in a significantly reduced bending capacity if installed upside down—the top side of the beam is indicated with a stamp.

Balanced Beams
Balanced beams are intended for use in multi-span or cantilevered applications. As either the top or bottom of the member are stressed in tension due to applied loads, balanced beams are manufactured with high-strength tension laminations on both the top and bottom.

Standard depths are in multiples of the standard lamination thickness:

Douglas Fir: 1-1/2 inches 
Alaskan Cedar: 1-1/2 inches 
Southern Pine: 1-3/8 inches

Glulam depths can be a minimum of (2) laminations, although our standard depths start at a minimum of (4) laminations. Our maximum standard glulam depth is 72 inches. Please contact us for information about producing glulam up to a maximum depth of 118 inches. 

Timberlab produces glulam in standard cross-section sizes. These sizes conform to standard sizes in the NDS up to 16 inches nominal width using either single or multiple-piece laminations (split laminations). The split lamination widths are based on the total laminating lumber widths in a layer minus an allowance to account for planning each side face after pressing to the finished width.

Timberlab can manufacture glulam up to 30 inches wide.

The Sunnydale Community Center will provide civic and recreational amenities inspired by nature for a community that has long-awaited such facilities.
