Glued laminated timber (glulam) should be manufactured in accordance with MS 758 : 2001
and Clause 4. All timber used for laminated members should be strength graded in
accordance with BS 5756 or equivalent Malaysian Standard.
NOTES:
1. The stresses given in this part of MS 544 apply only to timber graded in accordance with BS 5756 with respect to
structural tropical hardwoods. Because this standard is primarily for solid structural timber, manufacturers of glued
laminated timber may need to specify overriding requirements for wane, fissures and distortion. In deriving the
recommended stress for timber, estimates of 5 % lower exclusion values of the strength and stiffness were used.
Furthermore, the modulus of elasticity values no longer included element due to shear.
2. Grade and species for glulam that satisfy the requirement for strength classes are given in Table 1. Glulam
strength properties may be determined from the strength class properties given in Table 2.
