In the context of Australian commercial construction projects, "milled" refers to the process of transforming raw materials, such as wood or metal, into highly accurate building components using automated, computer-controlled machines, such as Computer Numerical Control (CNC) milling machines .

In the case of timber, milled products include sawn timber, which is cut from logs into different shapes and sizes, such as solid timber beams and rectangular timber sections . The milling process involves cutting, shaping, and smoothing the raw materials to produce the desired shape and size.

In Australian commercial construction projects, the term "milled" typically refers to the process of shaping, cutting, or forming materials using specialized machinery or equipment. This can include:

1. Timber milling: The process of cutting and shaping timber into various sizes and profiles using saws, planers, and other woodworking tools. Milled timber is often used for framing, flooring, and other structural components in construction projects.

2. Concrete milling: The process of removing a layer of concrete from a surface using a milling machine. This can be done to level uneven concrete, remove damaged or contaminated sections, or create a specific texture or finish.

3. Metal milling: The process of cutting and shaping metal using a milling machine. Milled metal components can be used in structural framing, cladding, and other applications in construction projects.

4. Stone milling: The process of shaping and polishing natural stone using specialized equipment. Milled stone can be used for countertops, flooring, and other decorative elements in construction projects.
