Industrial Plants — Steel Structure Fabrication and Turnkey Construction from One Partner
Fabrication, erection, and cladding of industrial production halls and steel structures. Steel structures to 800 tonnes. Free spans to 43.75 m. EN 1090-2 EXC4 certified. General contracting from design through turnkey handover. Since 1994.
One Partner from Raw Steel to Turnkey Handover — Fabrication, Erection, and Construction
Steiger acts as both the fabricator and the general contractor for industrial plant construction projects. We manufacture the steel structures in our own production facility, then erect and clad them on site — with full accountability from initial design through final handover.
This integrated approach eliminates the coordination risk and quality disputes that arise when fabrication and construction are split between separate contractors. Our clients receive a single point of contact, a single contract, and a single responsible partner for the entire project.
Certified to the Standards Industrial Construction Demands
Every steel structure we fabricate for industrial plant construction is manufactured under our certified quality management system. Traceability is maintained throughout the entire manufacturing process, from raw material to erected structure.

What Makes Our Industrial Plant Construction Different
Fabricator and Constructor in One
Most construction projects separate the steel fabricator from the general contractor, creating coordination disputes when structures do not fit, tolerances are missed, or delivery schedules slip. Steiger eliminates this risk entirely — we fabricate the structure and erect it ourselves, with single-point accountability throughout.
EN 1090-2 EXC4 Execution Class
Our steel fabrication is certified to EN 1090-2 Execution Class 4, for structural steel components. This certification applies to our full fabrication scope — from cutting and welding through surface treatment and dimensional verification.
Proven at Scale
We have completed industrial plant projects involving steel structures of 800 tonnes, free spans of 43.75 m, and building heights of 42 m. These are not theoretical capabilities — they are completed, documented reference projects.
Tailor-Made Solutions
We do not offer standard building catalogues. Every project is engineered to the client’s specific operational requirements, site conditions, and budget. Our engineers provide technical advice throughout the design phase to optimise cost and construction time.
Family-Owned Reliability Since 1994
Every project that leaves our production floor and construction site carries our name. We are not a high-volume contractor — we are a manufacturing and construction partner that treats each project as if it were our own. Direct access to decision-makers, flexible problem-solving, and long-term partnership focus.
