LG produces high quality copper tubes using the horizontal continuous casting and rolling method. This is the most sophisticated manufacturing method, maximizing working unit weight with high speed drawing. This method are simplified by eliminating the extrusion process.

LG copper tubes have excellent workability and corrosion resistance. They are characterized by high heat transfer and used in a wide range of tubing applications, such as condensers and evaporators for airconditioners, refrigerators and cooling units.

STRAIGHT TUBES
This adaptable copper tube is used for a variety of purposes, both domestic and industrial. It provides for all plumbing needs, supplying hot and cold water to buildings, and has extensive uses in most industrial fields, including as a heat exchanger for boiler and various other pipes.
