Railings on decks above 760 mm (30 in) are considered guard rails. [according to whom?] Guard rails have a specific building code requirement for both height and structural strength. Most U.S. commercial building codes require a 1,100 mm (42 in) guardrail on decks, and 910 or 1,070 mm (36 or 42 in) for a residential code depending on the state.

Cutting speeds on thin 1.2 mm (0.047 in) sheet can be as high as 25 m (82 ft) per minute. Most laser cutting systems use a CO 2 based laser source with a wavelength of around 10 μm ; some more recent systems use a YAG based laser with a wavelength of around 1 μm.
The most commonly used thickness range is from 1 ⁄ 8 to 3 inches (3.2–76.2 mm). The sizes of the most commonly used plywood sheets are 4 by 8 feet (1,220 mm × 2,440 mm) [20] which was first used by the Portland Manufacturing Company, who developed modern veneer core plywood for the 1905 Portland World Fair.
