What Krinner Schraubfundamente GmbH does

Krinner Schraubfundamente GmbH is a German specialty manufacturer of ground screws (Schraubfundamente) and matched installation equipment, headquartered in Straßkirchen, Bavaria. The company produces galvanised steel screw-in displacement piles across multiple product series (G, M, U, V, E, F, and the newly launched Vi-Series) that serve as concrete-free foundations for solar mounting structures, railway noise barriers, timber construction, and other light infrastructure. Krinner is one of the few manufacturers that vertically integrates production of both the screws themselves and the dedicated installation drivers (KRE, KRB, KRL, KRD series), and holds key engineering approvals including DIBt (German general construction approval), ICC-ES (North America), and an EPD under ISO 14025/EN 15804, with ISO 9001:2015 quality certification.

The business operates a multi-channel go-to-market: direct enterprise sales to infrastructure and solar customers, a specialist retailer and installer network, a dedicated e-commerce portal (krinnerscrews.io) targeting DIY and SMB buyers, active trade show participation, and a partner enablement program (KRINNER Connect). Named enterprise customers include Deutsche Bahn (railway infrastructure, with a co-developed Technology Center in Mühldorf opened in 2023), Mounting Systems and Terrasmart (solar mounting), Løvtag (treetop hotel/timber), and TUM Boring (academic/R&D). The company runs regional websites for Germany/Europe, North America, and International markets and is led by CEO Simon Baumgartner, appointed April 1, 2024. Employee count is reported in the 51-100 range, consistent with a mid-sized specialty industrial manufacturer. No revenue is disclosed.
