Industrial Manufacturing & Heavy Equipment — Precision Components for Global OEMs
Custom welded and machined steel components for machinery manufacturers, railway suppliers, and heavy equipment producers. EN 15085-2 certified. Components to 25 tonnes and 12 metres. 0.05 mm positional accuracy, laser-tracker-verified. Since 1994.
One Partner for the Complete Manufacturing Chain — From Raw Steel to Verified Component
At Steiger, we manufacture large-scale welded and machined steel components for OEMs, Tier-1 suppliers, and heavy equipment producers across Europe and beyond. Our integrated approach combines certified welding with advanced CNC machining under one roof, eliminating the dimensional failures and coordination disputes that arise when these processes are split between suppliers.
Whether you need machine beds, railway certified structures, wave generators, or custom heavy-duty assemblies, we manage the complete process — from raw material procurement through cutting, welding, stress relief, CNC machining, dimensional verification, surface treatment, and delivery.

What Makes Our Industrial Manufacturing Different
Integration Eliminates Risk
When welding and machining happen under one roof, there is no ambiguity about responsibility. We take full accountability for quality and dimensional accuracy from raw material to final verification. If adjustments are required during machining, we handle them — no coordination delays, no change orders between suppliers.
EN 15085-2 Railway Certification
Few manufacturers hold EN 15085-2 CL1 certification for railway welding. This qualification — combined with our dimensional accuracy and full traceability — makes Steiger a credible partner for railway OEMs and Tier-1 suppliers across Europe.
Scale and Precision Combined
Our 12-meter CNC gantry combined with Leica laser tracker verification allows us to achieve 0.05 mm positional accuracy on components up to 25 tonnes. This combination is rare and critical for heavy machinery, railway, and tyre industry applications.
Engineering Support from Concept to Delivery
Our International Welding Engineers and experienced manufacturing team do not just execute drawings — they identify potential manufacturing challenges, recommend material and process optimisations, and help clients avoid costly errors before production begins.
Family-Owned Reliability Since 1994
Every component that leaves our production floor carries our name. We are not a high-volume job shop — we are a manufacturing partner that treats each project as if it were our own. Direct access to decision-makers, flexible problem-solving, and long-term partnership focus.
