190 x 35

190mm x 35mm is a common size for structural timber used in construction in Australia. It is often used as a joist or bearer in residential and commercial building projects.

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

190mm x 35mm timber is typically made from softwood species, such as pine or spruce, and is commonly used in residential construction for floor and roof framing. It can also be used as a structural element in outdoor decking and pergola construction.

However, it should be noted that the specific use of 190mm x 35mm timber will depend on the design and requirements of the building or structure being constructed. The size and span of the joists or bearers will be determined by the load they need to support, and the spacing will depend on the structural requirements and the type of flooring system being used.
