About ALTEC Metalltechnik
ALTEC Metalltechnik GmbH, based in Schleiz, district of Crispendorf (Thuringia), has been developing and manufacturing PV mounting systems and individual components for photovoltaic installations for more than 30 years. The portfolio includes substructures for pitched roofs (tiles, beaver-tail tiles, slate, shingles, concrete roof tiles, metal roof panels), flat roofs, façade and wall mounting, as well as open-space/ground-mounted systems supplied as complete kits. Manufacturing takes place in-house from corrosion-free aluminium and stainless steel, supplemented by plastic components such as EPDM sealing tapes and plastic anchors. In addition to production, ALTEC offers planning, project engineering, design, structural calculations, bill of materials preparation, sample orders and support including training videos as well as an online planning tool (Solar Pro.Tool). Customers are solar technicians and installers for projects in residential construction, commercial properties, industrial companies, public buildings and agriculture. Delivery is made within the German mainland.
