Sectors served

Marine, offshore & subsea
We machine and fabricate parts for high pressures and corrosive marine conditions, from podded propulsion components to structural elements for offshore platforms. Fabrication, machining and corrosion protection are all done in-house, so the coating is never handed to a third party. Weight: 100 kg – 50,000 kg. Envelope: Up to 25 × 5 × 5 m (L×W×H). Materials: Marine-grade steels, carbon steel, stainless steel, duplex / super duplex. Surface treatment: NORSOK M-501 and C5-M, applied in-house. Class approvals: DNV, Lloyd's Register, Bureau Veritas, RINA — scope per project. Inspection: VT, PT, MT, RT.
Oil & gas / process equipment
We manufacture certified pressure vessels, tanks, piping modules and skids in strict compliance with PED and international safety standards. Design: EN 13445 / PED 2014/68/EU. Weight: 200 kg – 25,000 kg. Envelope: Up to 25 × 5 × 5 m (L×W×H). Materials: Carbon steel, stainless steel, duplex, super duplex. Inspection: VT, PT, MT, RT.
Rotating parts & shafts
Made to drawing for pumps, compressors, fans, turbines and power generation: impellers up to Ø 4,000 mm, rotors, shafts up to 3,250 mm, casings, and fan and blower components. Welded parts are stress-relieved, and rotating parts are dynamically balanced in the same order. Weight: 10 kg – 5,000 kg. Envelope: Ø 500 – Ø 4,000 mm. Balancing: Up to Ø 4,000 mm and 4,000 kg. Materials: Carbon steel, stainless steel, duplex / super duplex, titanium. Inspection: VT, PT, MT, RT.
Pulp & paper machinery
Precision spare parts and critical process components for mills in continuous production. Our priority is fast, reliable manufacturing that keeps your downtime short. Design: EN 13445 / PED 2014/68/EU. Weight: 200 kg – 25,000 kg. Envelope: Up to 25 × 5 × 5 m (L×W×H). Materials: Carbon steel, stainless steel, duplex. Inspection: VT, PT, MT, RT.
Mining & machine building
Heavy machine-building assemblies for the mining sector, precision-machined from wear-resistant materials for high-impact, abrasive service. Components: Machine assemblies, structural frames, conveyor elements. Materials: Hardened and wear-resistant steels. Conditions: High-impact, abrasive environments. Inspection: VT, PT, MT.
Defence
Precision manufacturing of regulated, mission-critical defence components, with full traceability, strict quality control and compliance with defence industry specifications. Focus: Mission-critical precision components. Requirements: Full traceability, strict QC, defence specifications. Capabilities: Welding, machining, assembly to military standards.

Why buyers choose us

Proven in demanding sectors
We are a specialised contract manufacturer and heavy engineering subcontractor delivering precision-welded, machined, and assembled products for demanding industrial applications.
Early DFM review
Before we build to print, our production engineers carry out a Design for Manufacturability (DFM) review to find potential failure points, optimise welding sequences and reduce your overall manufacturing cost.
Certified quality systems
Our operations are certified to ISO 9001, ISO 14001, EN ISO 3834-2 and EN 1090-2, and our documentation complies with PED.
Full material traceability
We guarantee full material traceability from prototype to series production. Weld integrity is verified by NDT (VT, PT, MT, UT) carried out by certified partners.
Scale and lifting capacity
With 18,000 m² of floor space and lifting capacity up to 160 tonnes, we can scale resources to your project timeline and handle very large components.
Heavy-haul port access
Our Tallinn site is 20 km from Muuga Harbour and 60 km from Paldiski Port, with direct heavy-haul road access that avoids city traffic. Oversized components up to 160 tonnes ship roll-on/roll-off to Europe and the Nordics.
Environmental responsibility
Waste, chemical safety and emissions are actively managed as part of our ISO 14001-certified operations.
