Planed square edge timber (PSE timber) is widely used in modern construction for internal joinery, cladding, furniture making, and visible structural work. Builders value its smooth surface and uniform profile, which help speed up installation and finishing. Common applications include door frames, window casings, skirting boards, and shelving. Historically, timber was rough-sawn and dressed by hand; today most PSE timber is machine-finished for consistent accuracy across different sizes and species.
You can find planed square edge timber in a variety of softwood and hardwood options, including oak for higher-end projects. PSE timber is available in standard and bespoke sizes, making it suitable for everything from framing to detailed carpentry. Its smooth faces require less sanding and preparation, saving time on site. Whether you are building to a traditional spec or working on contemporary interiors, PSE timber provides flexibility for a wide range of jobs.
