What is Glulam

What is Glulam

Glulam (glued-laminate timber) is a structural timber product manufactured by gluing together individual pieces of dimension lumber under controlled conditions.

  • The main reason for laminating is to produce larger size members than possible in solid sawn timber.
  • Laminating is an effective way of using high strength lumber of limited dimension to manufacture large structural members in many shapes and sizes. Glulam is used for beams and frequently for curved members loaded in combined bending and compression.
  • Glulam has become an indispensable engineered wood for building residential houses, gymnasium and others which require the use of structural materials with high performances in strength, fire resistance, and durability.
  • It reduces the overall amount of wood used when compared to solid sawn timbers by diminishing the negative impact of knots and other small defects in each component board.
  • Glulam is a completely eco-friendly material, and laminated timber beams can be used for everything from large industrial buildings to single family homes. Glulam offers wide freedom of architectural design.
  • The high strength and stiffness of laminated timbers enable glulam beams and arches to span large distances without intermediate columns, allowing more design flexibility than with traditional timber construction. The size is limited only by transportation and handling constraints.

Lay-up

Our Glulam products are mainly used as load-bearing structural members such as posts, beams, girders, arches, etc.

Because of the fact that Glulam products are made from laminae of natural wood without problematic defects, their qualities are stable and even. In addition, the laminae are glued together with superior Resorcinol Resin glue, the strengths of our Glulam products are about 1.5 times greater than those of solid wood.

Our Glulam products are 100% straight.

Lay-up

Glulam shall comply with the required performance as stipulated in MS 758 such as:

  • Design properties. They shall be the characteristic values for bending strength, modulus of elasticity, compression strength, shear strength and tension strength.
  • Glue line integrity. The requirements for glue line integrity shall be based on testing of the glue line in a full cross-sectional specimen, which shall be cut from the manufactured glulam member.
