Platinum Paper-faced Metal Drywall Beads and Trims are made with a unique, high quality paper laminated to various metal forms. The metal provides maximum strength and protection for the corner, while the paper provides reinforcement to prevent cracking caused by the movement or shrinkage of framing members. The result is a clean, precise corner that is long lasting, provides superior resistance to edge cracking, rust resistance and is not subject to fastener popping. Platinum Tape On L-Trims are used to finish rough edges of wallboard were it abuts other building components such as suspended ceilings, beams, masonry or concrete walls, untrimmed door and window jambs and bi-fold door openings. This trim can be quickly and easily installed using joint compound, so backing is not required, leaving a crack resistant finish that is not subject to fastener popping.G-4 1/2 L-TRIM 8’ PPR-MTL – 160831
