A seamless powder-coated wire with a rutile core, copper-covered, intended for single- or multi-bead joints. An innovative production technology determines a low hydrogen content (HD < 5 ml / 100 g) providing excellent mechanical properties at temperatures even up to (-60 ° C). IMT R811 wire is used in off shore construction, shipbuilding and steel construction.
