What Guntram End does

Guntram End GmbH is a family-owned German manufacturer specializing in stainless steel fastening systems for roofing and wall construction applications. Founded in 1966 in Saarbrücken, the company pioneered self-tapping stainless steel screws in Europe and today produces a focused product portfolio under the E-X brand, including self-tapping screws (E-X Type A and BZ), self-drilling screws (E-X BOHR), and seamless drilling screws (E-X RS and E-X RS HT). The product line is engineered for fastening steel and aluminum trapezoidal sheets, sandwich profiles, light panels, and fiber cement panels in safety-critical construction applications, and is backed by DEKRA Ü-Zeichen certifications (Reg.Nr. ÜZ-001/2004 and ÜZ-002/2004) and European Technical Assessments from DIBt (ETA-11/0174 with Annex 16 extension and ETA-13/0181).

The company operates from an 11,000 m² headquarters and central warehouse facility in Saarbrücken that holds the full product range in stock, enabling same-day order processing and express delivery for time-sensitive construction projects. Customers can specify and order products through an online configurator, phone, or fax, with a sales team of seven dedicated representatives plus purchasing, accounting, payroll, quality assurance, and IT functions. Pricing is structured around order-value thresholds: domestic orders in Germany under €400 incur €9.50 shipping and orders at or above €400 are freight-free; international orders under €3,000 ship EXW from Saarbrücken and orders at or above €3,000 ship CPT to destination.

Guntram End distributes directly within Germany and through a network of 8 foreign representation partners covering Iceland, Austria, France, the UK, Switzerland, Ireland, the Netherlands, and Slovenia, with stated delivery reach extending across Europe and into the Middle East. The company is led by Jürgen End and Katja End as Geschäftsleitung (executive management), and is independently held by the founding family with no external investors, parent company, or subsidiary structure. End markets are construction industry roofing and wall specialists, where the combination of regulatory certifications, proprietary stainless steel know-how, and immediate stock availability constitutes the core value proposition.
