PATECO
Finger
- jointed and laminated wood as applied to structural
members refers to materials glued up from smaller
pies of wood, with the grain of all laminations
essentially parallel to the length of the member.
In figure-jointed lumber, pieces of wood are glued
together and are interlocked along the joints to
produce longer ones. On the other hand, laminated
wood is made up of narrow pieces of wood glued edge
to edge to make wider ones.
TESTS SHOW THAT PATECO FINGER-JOINTED
AND/OR LAMINATED WOOD IS AS STRONG OR EVEN STRONGER
THAN SOLID WOOD.
Traditionally,
people used solid wood for structural and architectural
purposes requiring strength. They believe that
solid wood has a better strength properties and
can perform better than finger-jointed or laminated
wood. However, experiments & tests show
that finger - jointed / laminated lumber
is as strong or can actually be even stronger
than solid wood.
In
developed countries especially in Europe, people
preferred to use finger jointed lumber if the
requirements is 7 feet or longer. It is because
it is more stable and can
stand up against twisting, warping and bending.Irritating
natural defects such as wane and knots can be
removed and the profile is more stable. All these
contribute to the high-grade quality of lumber.
BENDING STRENGTH THAT IS TESTED IN EUROPE
At
Pacific Timber Export Corporation
(PATECO) we
use finger-jointed lumber in construction of door
elements and in producing some wood mouldings
like baseboard, cornice, T&G, etc.. Its bending
strength has been tested in Europe and was conducted
by Stitching Hout Research - SHR (Foundation for
timber research) instructed
by Stitching Keuringsbureau Hout - SKH (Timber
Inspection Bureau). The bending strength has been
determined by means of four-point bending test.
Results
showed that the finger jointed lumber split into
two but not along the portion where it was jointed.
Further, we also use KOMO-certified glue from
Europe in
our finger jointed lumber, which attributes to
its strength property. Thus
S4S kiln-dried jointed lumber passed the test
and complied with their requirements
