LCN FInishes

STANDARD POWDER COATED FINISH: LCN door closers feature the finest, state-of-the-art metal finishing process available. LCN powder coating provides superior protection against the effects of weathering and is an environmentally friendly process. The high quality, chip resistant finish is far superior to any previously offered. Corrosion resistance surpasses 100 hours salt spray testing (four times the industry standard). Non-metallic components also provide the same high resistance to the effects of the elements. All LCN products must be shipped with a finish.

OPTIONAL CUSTOM POWDER COATED FINISHES: LCN offers optional custom powder coat colors to compliment special installations. This provides a custom appearance and all the corrosion resistance of standard powder coated finishes at a nominal additional cost. See Downloads tab for available custom colors.

OPTIONAL PLATED FINISHES: Visible components such as covers, arms, fasteners, and finish plates are plated to match the selected finish. Surface mounted tracks are powder coated to complement the plated finish. Hidden assemblies such as cylinders, tracks, and mounting plates are supplied with a powder coated finish.

SPECIAL RUST INHIBITING (SRI) PROCESS: For installations where a higher level of protection against weathering, or the effects of a potentially corrosive atmosphere is required, LCN offers a special rust inhibiting (SRI) process. Ferrous metal components receive an SRI pretreatment and a powder finish coat in your choice of either an LCN standard color or optional extra charge custom colors. Closers treated with the SRI process exceed the 100 hour protection level available with standard LCN powder coated finishes.
