DeltaStrand™ Triangular Strand Lumber (TSL)
The Greenville Business Incubator in Greenville, Maine, through its partnership with the University of
Maine’s AEWC Center, is seeking an incubator tenant to commercialize DeltaStrand™ Traingular Strand
Lumber (TSL).
Triangular Strand Lumber (TSL) is a new Structural Composite Lumber (SCL) product developed and patented at the AEWC Center. TSL is made from four foot long logs which are reduced into strands of triangular cross sections, approximately 3/8” high/wide and then reconstituted into a structural composite using an exterior grade adhesive and radio frequency energy. The triangular shape allows for satisfactory consolidation of the composite in spite of the relatively large strand size, thereby minimizing void space and increasing density.
Unlike existing SCL products, which rely on significant densification of low-to-medium density species to achieve their enhanced mechanical properties, TSL can be made from higher density hardwood species such as ma ple, birch and beech, all abundant in Maine’s forests. The resulting product density is similar to existing SCL products, but due primarily to the inherent density of the species rather than densification of the wood fiber. Lower pressures are therefore required, which can reduce manufacturing costs and minimize damage to the wood fiber during hot pressing.
product is expected to
compete primarily in the
residential beam and
header market. TSL
may have a competitive
advantage over
LSL/Timberstrand and
PSL/Parallam in terms of
reduced resource costs.
