Stierli-Bieger

What Stierli-Bieger does

Stierli-Bieger AG is a privately held Swiss industrial machinery manufacturer, founded in 1936 and headquartered in Sursee, Switzerland. The company designs and builds hydraulic horizontal bending machines, straightening and bending presses, radial 360° bending machines (RADIAL line), flange straightening machines (FRM series), and welding turning devices (ROTATOR), with bending capacities spanning 8.5 to 880 tons. Control systems range from manual steering through NC to advanced CNC-W and CNC-WP variants with automatic angle measurement, spring-back compensation, and laser-supported straightening. A hybrid hydraulic-electric drive platform underpins the latest generation of horizontal bending centers, and the company maintains an in-house construction and controls engineering department to deliver customer-specific Sondermaschinen. The firm self-describes as a world market leader in high-quality hydraulic horizontal bending machines.

The company's product portfolio serves a diversified set of metalworking end-markets, including general metal fabrication (its primary segment), busbar and electrical power processing, steel service centers, vehicle construction, shipbuilding, rail machining, wind power systems, and high-volume series production. Sub-brands ROTATOR, RADIAL, FRM, and Hybrid Series are registered, and a strategic partnership with Boschert enables co-marketed busbar processing centers that integrate punching and bending. Pricing is quote-based and not publicly disclosed, with sales conducted through a worldwide network of machine trade representatives, direct factory sales from Sursee, an inquiry-driven website funnel, and active participation in major European machine trade fairs.

Revenue is generated primarily through one-time hardware sales of standard and custom machines, complemented by professional services including commissioning, training, transport, spare parts, and an aftermarket stream of certified used/refurbished machines. The company has 11-50 employees, operates as a Swiss Aktiengesellschaft, has no disclosed funding rounds, no parent company, and no public listing. No definitive ownership structure or investor affiliations are described in the available source data.
