Schöngen

What Schöngen does

Schöngen (legal entity: Karl Schöngen KG Kunststoff-Rohrsysteme) is a third-generation, family-owned German manufacturer of plastic pipe and molded-part systems, founded in 1956 and headquartered in Salzgitter, Lower Saxony. The company operates two production facilities in Salzgitter: Werk 1 in Salzgitter-Engerode (PVC cable protection pipes and headquarters/administration) and Werk 2 in Salzgitter-Watenstedt (established 1999, PE-HD and PP pipe production). Its portfolio spans PVC and PE-HD cable protection pipes, the Rocket Pipe trenchless jacking system, PP-HM and PE underground high-voltage cable pipes (Erdkabelrohr SHV for 220–380 kV), the Concept-HL wastewater pipe system (both jacking and solid-wall variants for trenchless and open installation), and the Concept-Drain drainage system with matching shafts. Proprietary technologies include the patented Multi-Raster-Schweißverbindung (a tensile-resistant welded connection without inner weld bead), the SSL low-friction inner surface, the ZRV tensile socket, and the Rocket Pipe constant-diameter trenchless connection. The business serves four primary verticals: energy supply, telecommunications, water disposal (municipal utilities), and construction, with a particular concentration in Deutsche Bahn and railway infrastructure projects and German high-voltage grid expansion. Approximately 130–140 employees are supported by an internal sales team of six, dedicated field sales representatives specializing in application technology and high-voltage cables, and trade fair participation (Schlauchlinertag, Kanalgipfel). Revenue is generated through quote-based B2B hardware sales of pipe systems, supplemented by technical documentation, installation guides, and planning materials as professional services; pricing is not publicly disclosed. The company holds DIBt, DIN CERTCO, EBA, HPQ, and Deutsche Bahn certifications, ISO 9001 (since 1996), ISO 14001, ISO 50001, and a Polish Institute of Building Technology approval.

Core offering

Schöngen manufactures and sells plastic pipe and pipe system products (PVC, PE-HD, PP-HM) for four end-uses: cable protection (energy and telecommunications infrastructure), trenchless and open-construction wastewater/sewage systems (Concept-HL), SHV underground high-voltage power cable ducts, and drainage pipe systems with manholes (Concept-Drain). All products are produced in-house at two Salzgitter plants and sold direct to enterprise and municipal buyers, including matching fittings, shaft systems, and accessories that form complete installation solutions.

Product overview

Schöngen is a family-owned German manufacturer (Karl Schöngen KG Kunststoff-Rohrsysteme) producing plastic pipe systems across multiple product lines. The portfolio comprises: (1) PVC cable protection pipes (Standard and Professional lines with adhesive or plug sockets, plus repair half-shells); (2) PE-HD cable protection pipes available as straight lengths with various socket types (plug, snap-lock, ZRV tensile-strength), ring bundles on drums, and multi-duct configurations; (3) Rocket Pipe PVC pipe jacking pipes for trenchless installation with color-coded warning system; (4) SHV underground power cable systems from PP-HM and PE for high-voltage applications; (5) Concept-HL wastewater systems including pipe jacking pipes (MV, MRV, MRS 2.0, ZRV, ML types) and solid-wall pipes (ARS 2.0, AM SN10, AM SN16) for both trenchless and open-cut construction; and (6) Concept-Drain drainage pipe systems with matching shafts for road, rail, tunnel, and landfill projects. The products are manufactured at two facilities in Salzgitter, Germany, and serve customers in energy supply, telecommunications, water management, and construction sectors.

Others

• Steinzeug-Keramo: European manufacturer of vitrified clay pipes for sewer and drainage applications. Adjacent to Schöngen's Concept-HL wastewater line in terms of end use (municipal sewer systems) but uses a different material (ceramic) and is relevant for cross-material competitive bidding on tenders.

Broad incumbents

• Geberit: Swiss-listed incumbent in sanitary and plumbing technology with broad portfolio including building drainage and supply pipe systems. Overlaps with Schöngen in DWV and building-related pipe systems, but is a much larger, publicly listed player with broader product range and different end-customer focus.

Regional players

• FRÄNKISCHE Rohrwerke: Family-owned German manufacturer of plastic pipe systems for drainage, sewer, cable protection, and automotive. Direct German-headquartered peer to Schöngen with similar product categories (cable protection, drainage, sewer) and a comparable mid-sized specialty manufacturer profile.
• Funke Kunststoffe: German manufacturer of PVC, PE-HD, and PP pipe systems for sewer, drainage, and cable protection. Comparable to Schöngen in materials, product range, and German municipal/utility customer focus.
• egeplast (ege gruppe): German plastic pipe manufacturer specializing in PE-HD pressure and cable protection pipes, with a strong German utility and telecom customer base. Direct competitor in PE-HD cable protection pipes, particularly for fiber rollout and energy infrastructure.
• Poloplast (Wietersdorfer Gruppe): Austrian manufacturer of PP and PE pipe systems for building drainage, sewer, and infrastructure. Comparable to Schöngen's PP-HM wastewater and Concept-HL product line, primarily active in DACH region.

Direct peers

• Pipelife (Wienerberger): One of Europe's largest plastic pipe manufacturers, offering PVC, PE, and PP pipe systems for cable protection, sewer, drainage, and water distribution. Closest direct peer to Schöngen in terms of product portfolio, end markets (utilities, telecom, construction), and European reach.
• Wavin (Orbia): Global plastic pipe producer (part of Orbia) covering water management, sewer, cable protection, and stormwater systems. Highly comparable to Schöngen's cable protection and wastewater pipe lines, with overlapping customer base in municipal infrastructure and telecom ducting.
• Uponor: Finnish plastic pipe manufacturer with strong presence in PE-HD and PP pipe systems for water, sewer, and cable protection. Comparable to Schöngen's product mix in PE-HD cable protection and PP-HM wastewater pipes, with similar applications in municipal and telecom infrastructure.
• REHAU Industries: German-headquartered polymer solutions company producing PE-HD, PP, and PVC pipe systems for cable protection, building services, and infrastructure. Comparable to Schöngen in materials, end markets, and German manufacturing heritage, with broader product breadth.
