What SIHGA does
SIHGA GmbH is an Austrian manufacturer of specialized fastening technology, mounting systems, and structural connectors focused on timber construction, with additional product lines serving terrace, facade, and concrete/brick applications. Founded in 2003 and headquartered in Ohlsdorf bei Gmunden, Upper Austria, the company develops, patents, and manufactures its products domestically, offering system connectors (Modulix, IdeFix, Winkelix, ProziFix), height-adjustable supports (JustiFix II JK, TefaFix), invisible fastening systems (GleitFix, SenoFix, LamellenFix), and specialized tools (Orakelix precision leveling instrument). Notable technical components include the proprietary SIHGAMID glass fiber-reinforced plastic (adapted from space research), ETA-23/0821-certified structural products, BIM data hosted via PARTCommunity, and integration of SIHGA connectors as native elements in the TCCdesigner software for timber-concrete composite floor calculation per ONR CEN/TS 19103:2022.
The company operates a B2B e-commerce model with mandatory business account registration requiring a VAT ID, selling exclusively to professional customers across the timber construction value chain: carpenters and timber builders (Zimmerer), architects and structural planners, timber dealers, and garden/landscape companies. Pricing is opaque (login required), with tiered free-shipping thresholds across Austria, Germany, South Tyrol/Italy, France, and Poland, and worldwide shipping available on request. SIHGA augments hardware unit sales with a substantial content and services layer: digital planning tools (Terrace Planner, S3 statics software, Fassade BeziFix Bemessung), training (SIHGA Academy), on-site product demonstrations (Tourbus mobile unit), the TimberTalk expert interview video series, and the Schraubenrücknahme screw recycling program. Active customer segments span hospitality, residential wood construction, landscape architecture, sports infrastructure, cultural heritage, and commercial real estate development, with the company led by Managing Director DI Dr. Marc C. Simmer, MBA as majority shareholder.

SIHGA competitors and assessment
Company assessmentDirect peers
- Rothoblaas: Italian-headquartered specialist in timber fastening systems, structural connectors, and building hardware for wood construction, with strong European and growing global presence. Closely comparable in product breadth, focus on timber-only solutions, and emphasis on engineered/mass-timber applications.
- Knapp GmbH: Austrian manufacturer of concealed timber connectors (e.g., RICON, GIGANT) widely used in European timber framing and mass-timber projects. Directly comparable to SIHGA in product category, customer base (carpenters and timber builders), and B2B/specifier-driven go-to-market.
- HECO-Schrauben GmbH & Co. KG: German manufacturer of wood screws and engineered fasteners for timber construction, facade, and concrete applications. Closely comparable product portfolio (wood screws, system fasteners) and similar DACH-centric B2B customer base of carpenters and timber builders.
- Eurotec GmbH: German specialist in fastening systems and hardware for timber construction, decking/facade, and concrete anchoring. Directly comparable in product categories (terrace pedestals, facade connectors, structural wood screws) and B2B e-commerce distribution model.
- Sherpa Connection Systems: Austrian manufacturer of concealed timber connectors for main-secondary beam and panel connections in engineered wood. Comparable in domain specialization (timber-only), DACH market focus, and premium concealed-connection positioning.
- Pitzl Metallbau GmbH & Co. KG: German/Austrian manufacturer of structural connectors and post bases for timber construction (e.g., Pitzl column bases, concealed connectors). Direct competitor in system connectors serving the same DACH carpenter and engineered-timber customers.
Broad incumbents
- SFS Group: Swiss-listed global supplier of engineered fastening solutions and components for construction, automotive, and industrial markets. Overlaps with SIHGA in fastening technology for construction applications but serves a much wider set of end-markets.
- fischer Group (fischerwerke): Major German manufacturer of fastening solutions including screws, anchors, and chemical fixings across construction, wood, and concrete. Comparable in concrete anchors and Bauchemie product lines but operates across a far broader construction portfolio.
- Simpson Strong-Tie: Large global manufacturer of structural connectors, fasteners, and anchoring systems for wood, concrete, and steel construction. Comparable in the connector and fastener categories but operates at much broader scale and across all construction materials, not specialized to timber.
Emerging players
- PMJ-tec GmbH: German niche manufacturer of specialty wood screws and fastening systems for timber construction. Comparable product focus and target customer base, with a smaller catalog and narrower geographic footprint than SIHGA.
