About SGD Gap Sealing

SGD Servicegesellschaft für Verladetechnik mbH & Co. KG (brand SGD Gap Sealing) manufactures gap seals for sealing gaps and slits at doors, gates, automatic sliding doors, lift tables, loading ramps and dock levellers. The SAMT, SAMTS, SAMTA, SAML and SAMLH systems consist of a hygienic, waterproof specialty fabric with a robust, smooth surface and a fibre-reinforced sealing lip, and are supplied with magnetic strips (metal insert) on one or both long sides. The trademark- and technically protected system closes gaps from 4 to 55 mm continuously and draught-proof, and can be retrofitted without drilling, screwing or riveting. The seals are cut to the desired length and are used in many industries, especially in food and meat processing, frozen and refrigerated logistics, retail, freight forwarding logistics as well as in the chemical, pharmaceutical and paper industries. Reference customers include Amazon, Havi Logistics, Nordfrost, Westfleisch, IKEA, Aldi and Edeka. Locations are the Papenburg/Aschendorf branch of doors and parts Germany GmbH and the Wettringen site.
