Satellite Metals & Tubes's core business is the production of 904l stainless steel pipes & tubes for the water and gas distribution network, sewage treatment and fire protection. Furthermore, Satellite Metals & Tubes has built up strong brands supplying valves and controls for water treatment, dams & reservoirs, HVAC, chemical processing, marine and other industrial sectors. Satellite Metals & Tubes products are designed to the major international standards and are sold in more than countries worldwide. When dealing with the Satellite Metals & Tubes expect quality, reliability, functionality and long lifetime in service.
Satellite Metals & Tubes has not just veryfied the design but we also work in the optimization in order to obtain the best possible and most competitive solution in both the technical and commercial aspects.
In that year, the company began manufacturing stainless steel and established divisions for bright bars and for flanges and forging, and started exporting bright bars. Almost every year since then Satellite Metals & Tubes has added a type of 904l stainless steel pipes & tubes to its range, including sections and profiles, fasteners, wire and wire rods.
