What Gunnebo Fastening does
Gunnebo Fastening is a Swedish industrial manufacturer of mechanical fastening solutions headquartered in Gunnebo, Sweden, with continuous operations since 1764. The company designs, develops, and produces screws (including collated), nails (including collated), construction brackets/connectors, expansion anchors and plugs, chemical anchor mortars, and inspection hatches, alongside proprietary corrosion-protection coatings (Impreg®+, Zink Flake, Zink-Nickel, Protec+). The product range is engineered for professional construction use across wood, concrete, masonry, and steel substrates, with ETA/CE-certified lines for structural load-bearing applications and product variants tuned for the Nordic climate.
The business operates a two-sided value chain. On the physical side it serves professional carpenters, contractors, and larger construction/industrial end-users through an exclusive Swedish and Nordic dealer/reseller network (both building materials retailers and specialized fastener distributors). On the digital side it bundles each sale with specifier-facing engineering tools — SolidWood (a structural dimensioning program), a BIM library in multiple CAD formats, the GuideCenter suite of product-selection guides, and Trallguiden — which embed Gunnebo / Simpson Strong-Tie products into architects' and structural engineers' workflows. The company does not sell directly to end customers and does not publicly disclose pricing or revenue.
At year-end, the legal entity was renamed from Gunnebo Fastening Systems AB to Simpson Strong-Tie AB, formally unifying the Swedish operations under its US-based strategic parent, Simpson Strong-Tie, a global leader in structural construction connectors. Operating geographies disclosed are limited to Sweden and the Nordics, and the company employs 251–500 people, primarily at the Gunnebo plant and headquarters site.
