FAQsView More

What is camber?

Camber is a "crown" purposely built into a glulam at the time of manufacture. It is most often desired in long span applications to counteract deflection. Camber does not affect the strength of the beam. Residential stock beams are normally made in either 5000' radius or zero camber, while other engineered wood products are zero camber. Most residential spans are less than 24', and the camber derived from a 5000' radius falls inside industry accepted manufacturing tolerances for zero camber beams. These glulams are increasingly popular because they contribute to a "flat" framing system without humps.
