What is the difference between LVL and PSL?

PSL beams are generally more expensive than glulam, LSL, or LVL beams. Laminated Veneer Lumber (LVL) is a commonly available engineered product that is manufactured similarly to PSL. Available sizes, strengths, and stiffnesses are similar to PSL but are generally cheaper, making it a commonly specified beam type.

What is the difference between Microlam and LVL?

What Laminated Veneer Lumber (LVL) Is. Much like plywood, thin sheets of wood are sandwiched and bound with super-strong glue. Unlike plywood, Microllam and other LVLs are solid and intended to carry loads. This means that LVL has greater strength in a smaller size than solid lumber.

How far can a glulam beam span without support?

How far can a 12 glulam beam span?

In large open spaces, glulam beams can span more than 100 feet. One of the greatest advantages of glulam is that it can be manufactured in a wide range of shapes, sizes and configu- rations.

Is glulam stronger than timber?

Glulam has been shown to be as strong as steel, with greater strength and stability than similarly sized standard dimensional lumber. As compared to solid sawn lumber posts, Glulam is a stress-rated engineered wood product composed of layers of bonded wood laminations running the length of the post.

How far can a PSL beam span?

* The span and load tables in this guide cover beam spans up to 60 feet; however, 2.2E Parallam® PSL beams can be delivered in lengths up to 66 feet.

What is the strongest wood beam?

Perhaps the strongest wood beams made this way are Douglas fir. There may be a stronger wood, but I’m not aware of it. Today, lumber mills make beams like they make plywood. They use layers of solid wood that are glued together to make incredibly strong structural engineered timbers.

How big of a beam do I need to span 20 feet?
