Hofstetter AG Stahlbau

What Hofstetter AG Stahlbau does

Hofstetter AG Stahlbau is a privately held Swiss steel construction company headquartered in Bernhardzell (Lee), Canton of St. Gallen, operating primarily in Eastern Switzerland and Liechtenstein. Founded in 1960 by Jakob Hofstetter in St. Gallen, the firm is now under the ownership of Marcel Kaiser, who acquired the business in 2017 as part of a planned succession from Jörg Hofstetter. The company employs approximately 20 qualified staff and operates from a single workshop facility of over 2,500 m² equipped with cranes capable of lifting up to 12 tons.

The company's offering spans the full project lifecycle of structural steel work: planning, certified fabrication, on-site assembly, and in-house corrosion protection (steel shot/grit blasting and wet painting). Core product lines include industrial and commercial halls/roof structures, pedestrian and cycling bridges, stair towers, and special constructions (renovations, structural reinforcements, masts, crane substructures). Since 2021, fabrication has been certified under EN 1090-2 EXC3 (factory production control for load-bearing steel structures up to execution class 3, enabling dynamically stressed constructions) and EN ISO 3834-2 (comprehensive welding quality), both of which are prerequisites for many public-sector infrastructure tenders. Reference projects include 90-meter pedestrian walkways, 35-ton bridge components, and 32-meter mobile phone masts.

Hofstetter generates revenue on a project-by-project basis through direct sales to industrial enterprises, municipalities, construction firms, and infrastructure operators. Pricing is fully custom-quoted per project scope; no standard tiers or recurring SaaS-style contracts exist. In addition to construction work, the company monetizes its in-house corrosion protection capacity by selling shot blasting and wet painting services to third parties — a service line that was vertically integrated in 2023 when Hofstetter acquired the steel grit blasting and paint shop of a former partner located at the Lee site. The company's go-to-market is primarily sales-led within Eastern Switzerland, supported by a website, LinkedIn, Facebook, and Instagram presence, and by membership in Stahlbau Zentrum Schweiz (SZS).
