What Overlasko Konstruktie does

Overlasko Konstruktie BV is a family-owned Dutch metalworking and heavy steel fabrication company founded in 1993 and headquartered in Nieuwdorp, Zeeland, Netherlands. The company operates a single integrated facility offering a full-stack service portfolio — design (Autodesk Inventor Professional, AutoCAD Mechanical), cutting (ESAB Suprarex SXE 4500 plasma/oxy-fuel bridges, 20000x3800mm table), welding (GTAW/GMAW/FCAW/SMAW/SAW qualified to DNV/ABS/BS/LRQA/AWS/NORSOK/BV/EEMUA 158 standards), CNC machining (turning up to ø4000mm, boring/milling up to 12000x4300mm with 50-ton turntable, SHW PowerSpeed 6 bed mill), CNC plate rolling and bending (up to 700T press brakes), assembly and testing (LRS-certified load tests, hydrostatic pressure tests), blasting and conservation (via partner Nooijer), and heavy transport (up to 300 tonnes including SPMT). It is DNV-certified to ISO 9001, EN 1090-1 EXC Class 4, and ISO 3834-2, and holds LRQA stamping authority to re-certify 3.2 materials. The company's customers are enterprise buyers in offshore (oil, gas, wind), marine and shipping, machine building, (petro)chemical, and construction/transport; named reference clients include Van Oord (2 x ~100 m.T. spreader beams for vessel Svanen), Mourik (winches for Maasstuw Sambeek and Belfeld), and Spacelift/Zwagerman group (35,000 m.T. crane, 2009).

The business model is project-based, one-off custom manufacturing rather than recurring product or subscription revenue. All revenue is earned per project/delivery through custom metalworking services, in-house and on-site assembly and testing, transport (including SPMT rental), and blasting/coating services. Go-to-market is exclusively direct enterprise engagement — customers contact the company via phone or web form to scope and quote specific projects; there are no resellers, distributors, or self-serve channels. Marketing is minimal: a bilingual (Dutch/English) website with service pages and a project showcase, supplemented by direct outreach and word-of-mouth within the Dutch offshore and marine industrial cluster near Vlissingen-Oost. Pricing is not publicly disclosed and is tailored per project. Ownership sits with the Van Gurp family (S.A. van Gurp and T.A. van Gurp in Purchase/Sales, J.J. and H.J.S. van Gurp in Planning/Transport, Samuël van Gurp as Commercial Director), with no external investors, parent company, or public funding rounds identified. The company has no digital product surface — no app, no API, no software offering — and is firmly in the physical-services industrial category.

Direct peers

• Sif Group: Dutch manufacturer of large-diameter steel foundations (monopiles, transition pieces) for the offshore wind industry. Comparable as a Netherlands-based heavy steel fabricator with a North Sea offshore wind customer base, though more specialized and larger-scale than Overlasko.
• Eekels Technology: Dutch technical services provider delivering electrical, mechanical, and automation solutions for marine, offshore, and industrial markets. Comparable in size, customer overlap (Dutch marine/offshore), and project-based service model, though Eekels skews more toward MRO/retrofit.
• Smulders: Belgian-Dutch heavy steel fabricator producing offshore wind foundations (jackets, monopiles, topsides), offshore substations, and civil/industrial steel structures. Highly comparable as a Benelux-based certified fabrication shop serving the same offshore/marine customers Overlasko targets.
• Heerema Fabrication Group: Dutch heavy steel fabricator for offshore oil and gas and offshore wind (jackets, topsides, modules). Operates large-capacity fabrication yards in the Netherlands with EN 1090 and DNV-class qualifications, directly comparable to Overlasko's certified heavy steel offering.

Others

• Mammoet: Dutch heavy lifting and engineered transport specialist. Overlaps with Overlasko's heavy transport / SPMT capability and shares the offshore/marine customer base, but is a transport-and-rigging specialist rather than a metal fabricator.
• Damen Shipyards: Major Dutch shipbuilding group with yards across the Netherlands and Belgium. Not a fabrication peer, but a key customer category for Overlasko (deck equipment, winches, seafastening, ship repair work).
• Allseas: Swiss-based but Dutch-rooted offshore contractor specializing in pipeline lay and heavy offshore installation. Functions primarily as a buyer of heavy steel fabrication services and SPMT/heavy transport rather than a competitor, but useful as a reference customer profile.

Broad incumbents

• VDL Groep: Large Dutch industrial conglomerate with metalworking, subcontracting, and heavy vehicle activities including VDL Steelweld. A broader incumbent in the Dutch steel fabrication market, far larger and more diversified than Overlasko but addressing adjacent customers.
• Royal IHC: Dutch shipbuilder and supplier of marine equipment for dredging, offshore, and mining. Overlaps with Overlasko on deck equipment, winches, and heavy marine fabrications but is a far larger, integrated OEM rather than a custom job shop.
• Huisman Equipment: Dutch manufacturer of heavy construction equipment, cranes, and offshore installation tools. Relevant as a Benelux-based heavy steel and machinery peer; however, Huisman designs and serial-produces branded products rather than offering custom one-off fabrication services.
