THREE CHEERS FOR SAFETY.
ADVANTAGES
Safety in the finger-jointing
Safety in the grading
To be designed and dimensioned
like glue laminated timber
Up to 20% material savings
compared to conventional
finger jointed structural timber
Up to 15% cost savings compared
to glue laminated timber
SAFETY IN TRIPLICATE
The safest bet is fully tested!
Every GLT® (tested glulam beam) and
its finger joints are exhaustively tested
under extreme conditions.
SAFETY STEP 1:
QUALITY GRADING
Specially selected and certified sawn timbers
are produced in our own saw mill, technically
dried and pre-graded by our specialists
SAFETY STEP 2:
HIGH-TECH STRENGTH GRADING
Strength-related deficiencies in the timber
are detected and rigorously eliminated using
state-of-the-art X-ray and laser technology.
SAFETY STEP 3:
PATENTED TENSILE TEST
The strength of load-bearing components is
usually only monitored on a random basis not so with GLT®. After finger jointing, every
GLT® is subjected to the patented tensile test
according to Austrian Standard B 4125 and its
quality is therefore completely assured.

Tested finger-jointed structural timber
beams are individually tested for strength

Scope of validity
The surface qualities shown are applicable on delivery.
(1) knot diameter up to 40% of cross-section height or width permissible
(2) loose knots, falling-out knots, knocked-out and isolated knots with black wane permissible up to 20 mm knot diameter
(3) the mean annual-ring width according to EN 1310 is applicable. An area of 25 mm around the pith is not taken into account. The
requirements and grading criteria specified on the basis of the table must be complied with due to unavoidable grading errors and
fluctuations in moisture content within the cross-sections in 95% of the pieces supplied. The grading parameters of EN 14081
are complied with during mechanical sorting and therefore deviations from the sorting parameters shown in the table may occur.

1) In GLT ® tested glulam beams, the values for bending strength, tensile strength and compressive strength can be multiplied by the factor k pl according to ETA-13/0644.
2) The shear strength must be multiplied by the factor k cr (crack factor).

FINGER JOINTED
STRUCTURAL TIMBER
is impressive due to the naturalness of its
surface, even in exposed areas. The tensiletested variant GLT® - tested glulam beams makes
building with finger jointed structural
timber safer and more efficient because GLT®
may be dimensioned like glue laminated timber.
