What is S4S Trim Board
S4S trim board stands for "surfaced on 4 sides" trim board. This term is commonly used in the construction and carpentry industry to describe a type of lumber or board that has been planed and smoothed on all four sides. Each side of the board is precisely machined to create a smooth, consistent surface, free of rough edges or irregularities.
S4S trim boards are often used for various interior and exterior trim applications, such as baseboards, crown molding, window casings, and door frames.
