90 x 45

One common use of 90mm x 45mm timber is as a wall stud. Studs are vertical structural members that support the weight of the walls and are typically spaced at regular intervals along the length of the wall. 90mm x 45mm timber is also used for framing smaller structures such as garden sheds, pergolas, and fences.

In addition to wall framing, 90mm x 45mm timber can be used for bracing, which involves adding diagonal or horizontal members to reinforce the structure against lateral forces such as wind or earthquakes. It can also be used as a bearer for smaller loads, such as in deck construction or other outdoor structures.

As with all structural timber sizes, the specific use of 90mm x 45mm timber will depend on the design and requirements of the building or structure being constructed. The size and spacing of the timber will be determined by the load they need to support and the structural requirements of the building.

there is a significant difference between 90mm x 35mm and 90mm x 45mm timber in terms of their load-bearing capacity and structural applications.

90mm x 45mm timber is larger and thicker than 90mm x 35mm timber, which means it has a higher load-bearing capacity and can support heavier loads. As a result, 90mm x 45mm timber is commonly used for structural applications such as floor joists, roof rafters, and wall studs, where it is required to carry significant weight and maintain structural integrity.

90mm x 35mm timber, on the other hand, is smaller and thinner than 90mm x 45mm timber, which means it has a lower load-bearing capacity and is better suited for lighter structural applications. It is commonly used for smaller structures, such as garden sheds, pergolas, and fences, where it is not required to support as much weight.

In summary, the choice between 90mm x 35mm and 90mm x 45mm timber will depend on the specific structural application and the load-bearing requirements of the project. If heavier loads need to be supported, then 90mm x 45mm timber would be the better option, while 90mm x 35mm timber may be more suitable for lighter structural applications.
