Industrial Steel StructuresFrom Fabrication to Turnkey Installation
Complete steel structure solutions for industrial buildings up to 800 tonnes. We combine in-house fabrication with general contracting expertise: design support → manufacturing → installation → cladding → turnkey handover.
Complete Control from Workshop to Construction Site
At Steiger, we specialize in industrial steel structures that demand both manufacturing precision and construction expertise. Our integrated approach combines certified steel fabrication with general contracting capabilities, eliminating coordination delays and quality risks.
Whether you need production halls, multi-storey industrial buildings, or complex steel structures with simultaneous installation of production equipment, we deliver complete solutions from design support to turnkey handover. With over 7,000 m² of production area and 9 bridge cranes, each with a 35-tonne capacity, we manufacture, transport, and install structures up to 800 tonnes.

What Makes Our Approach Different
Scale and Certification Combined:
Our EN 1090-2 EXC4 certification combined with 7,000 m² production capacity and 35-tonne crane capacity allows us to manufacture and install structures up to 800 tonnes. This capability is rare and critical for large industrial projects.
Engineering Support from Concept to Commissioning:
Our two International Welding Engineers and experienced construction team don’t just execute drawings—they help optimize designs for manufacturability, cost, and construction efficiency. We provide design feedback, material recommendations, and process improvements.
Family-Owned Reliability:
Since 1994, every structure carries our name. We’re not a job shop focused on volume—we’re a manufacturing partner that treats your project as if it were our own. Direct communication with decision-makers, flexible problem-solving, and long-term relationship focus.
