Overview
About Siera s.a.s.
Who we are
Siera has refined skills in processing metal tubes and in providing customized workings. We are spelialized in: - Pipe bending - Pipe forming - Flange bending, profile bending - Inert gas shielded arc welding (MIG/MAG) - Inert gas shielded arc welding (TIG) - Manual electrode welding - Robot welding - Stud welding - Sawing - Turning - Milling We realize on tubes, sheets, section bars and drawn products several metal processes and treatments such as bending, welding, turning, cutting, flowdrilling, satinizing, etc., also on tubes with small diametre. We produce components and accessories (for example handles, knobs, legs for tables, tubular benches) for furnishing, shipping industry, cycling and other industries. We work on drawing or sample.
