About HSI
HSI HERMANN SCHWERTER Iserlohn GmbH is a fastening technology company based in Iserlohn. Its product programme includes fasteners such as structural timber screws, timber connectors and fittings, window frame screws and drywall screws as well as anchors, plus a range for patio and garden construction, castors and wheels, furniture fittings and tools. A second focus is solar mounting: the company supplies substructures and mounting profiles made of aluminium and stainless steel for pitched roofs, flat roofs, green roofs, facades, trapezoidal sheet metal and standing seam roofs, as well as module holders for balcony power plants. For solar installations, HSI provides planning on customer request, including structural calculation of the mounting system, and supplies installation instructions. In addition, screw foundations made of structural steel S355 with hot-dip galvanized surface are offered, whose installation is documented with screwing-in equipment. For specialist retailers, the company also assembles customized product presentations for the point of sale. Distribution is via its own online catalogue and specialist retail partners.
