About Stratosteel

Manufacturer and industrial architect.

Stratosteel s.r.o., founded 2009, Slovakia, EU. We manufacture heavy industrial parts and we architect the route a part takes from drawing to delivery. One contract, single responsibility, either way.

Who we are

We take a drawing and return a finished, certified part: cast, forged, welded, machined, inspected and delivered under one contract. The buyer deals with one partner and one accountable name, not five suppliers and the integration risk between them. We own no machines, on purpose. We own responsibility for the result.

We are the sales force of our production plants. When our plants prosper, everyone prospers: the buyer gets stable capacity, the plants get serial work, and one name stays accountable for both.

The Slovak core of the network is 5 plants under long-term agreements covering heavy machining to 50 t static and 30 t rotary, 5-axis precision to IT6, vertical turning to diameter 2 700 mm (carousel to 15 t), deep drilling diameter 400 x 6 000 mm and weldments to 10 t under EN ISO 3834-2. For heavier scope, long-term EU partner plants extend the envelope: steel castings to 50 t single piece, ductile and grey iron on project basis, open-die forgings on project basis, weldments to 64 t x 45 m. Stratosteel holds the contract and the responsibility across all of it.

2009 to today

The legal entity was founded on 27.06.2009 and carries seventeen years of unbroken registry, tax and banking history under one company ID. In February 2025 it took the Stratosteel name as the network model formalized. The manufacturing craft behind it is older than the name: the founders spent twenty years on the shop floor before building the network. Active programs today: a 6-year serial weldment and machining program for a forestry equipment OEM, a serial defence component program, and network foundry production running in major OEM machines. Details on the proof page.

Production footprint

Production runs in 5 plants in Slovakia under long-term agreements, coordinated and contractually carried by Stratosteel s.r.o.: heavy machining, 5-axis precision, vertical turning, deep drilling and certified weldments. Casting and forging scope runs in long-term EU partner plants and is stated separately wherever envelopes appear. The registered seat in Banska Bystrica is the legal address, not a production site. Full plant list with locations and capabilities is disclosed under NDA. All plants are auditable.

3NEXT, where it comes from

3NEXT is not a CSR programme. It is how the company is built. It started small and literal: blood given three times a year, and a mountain-bike race run for others (e3nexus.eu). As the network grows, three percent of every deal closed goes forward, toward founding the Stratosteel Foundation for the next generation. Built into the deal, not a donation. Profit is the fuel. It is not the point.
