190 x 45

190mm x 45mm is a common size for structural timber used in construction in Australia. It is often used as a joist, stud or bearer in residential and commercial building projects.

Joists are horizontal structural members that support the flooring system, while studs are vertical structural members that support the walls. Bearers are horizontal structural members that support the weight of the structure above them, such as the walls and roof.

190mm x 45mm timber is typically made from softwood species, such as pine or spruce, and is commonly used in residential construction for floor and roof framing, wall framing and bracing. It can also be used as a lintel over door and window openings, or as a structural element in outdoor decking and pergola construction.

The specific use of 190mm x 45mm timber will depend on the design and requirements of the building or structure being constructed.
