Beam is generally made of wood or timber, steel and rcc concrete providing with reinforcement Steel. It is load bearing structure and flexural member of frame structure that supporting the floor joist that vertical transfer all the incoming dead load, live load and self load of roof to the post or column via post- beam joint through development length of structure element to the foundation and finally to the soil.

A 4 ply wood beam are made when 4 beams are nailed together. A 4 ply 2×8 beam are made when 4 piece of 2×8 lumber are nailed together represented as 4-2×8 or 4 ply 2×8. A 4 ply 2×10 beam are made when 4 piece of 2×10 lumber are nailed together represented as 4-2×10 or 4 ply 2×10. A 4 ply 2×12 beam are made when 4 piece of 2×12 lumber are nailed together represented as 4-2×12 or 4 ply 2×12.

4 ply of 2×8, 2×10 & 2×12 different grade lumber (#1, #2, #3) are made of different species of wood such as Douglas fir, Hem fir, spruce pine fir used for Construction application in commercial and residential structure including beams, header etc.

Size of beam generally depending on span between two support and all the load acting on it. Beam is structural member subjected to flexural stresses and shear forces . The size of the beam (width and depth of beam) are governed by the different type of shear forces and stresses. When the beam is subjected to loading the bending moment is developed and the moment carrying capacity of the beam depends mainly on the depth of the beam.

In this article we mainly know about how far can a 4 ply 2×12, 2×10 & 2×8 beam span and also know about many species of wood Douglas fir, southern yellow fine, spruce pine fir, others hardwood of different grade of lumber #1, #2 or #3 are used for beam.

A wood beam is a structural support made from different species and grade of wood wood. They are most commonly used in wood frame structures like small houses, although they can be used in other types of construction as well. Beams are designed to resist bending when stressed by weight or forces like high winds

They are included in structural elements like floors and roofs to distribute the weight of the structure and provide support. Historically, wood was the most common construction material in many regions of the world in US, UK, Canada and solid wood beams were a preferred method of structural support.

The type of wood and size of the beam both play a role in how much weight a single wood beam will be able to bear.

Highly dense, close-grained woods of different species tend to be preferred because of their increased strength, as well as resistance to insects and rot. The wood beam can be cut in a solid block, I, or H shape, depending on the needs of construction.

In some cases, multiple pieces of wood are stacked and bound to create a single beam. If 2 beam nailed together known as 2 ply beam such as 2-2×10 or 4×10, if 3 beam nailed together known as 3 ply beam such as 3-2×10 or 6×10, if 4 beam nailed together known as 4 ply beam such as 4-2×10 or 8×10 and if 5 beam nailed together known as 5 ply beam such as 5-2×12 or 10×12.
