Softwood PSE V Redwood 75 x 100mm is a Planed Square Edge timber that can be used as construction stud timber, for furniture and internal joinery applications where a smooth finish is required. The timber has been machined to create square corners making it ideal for use with internal joinery work. The standard grade PSE has been machined from “fifths” redwood which features fewer knots. PSE timber can be used with nails and screws and once applied can be glued, stained, varnished and painted.
