High-Spec Steel Assemblies

Complex machined welded constructions, assemblies, sub-assemblies and complete products

The High-Spec Steel Assemblies division forms a separate branch within our company, in which there is collaboration with a number of select parties.

We have been supplying both components and assembled parts to the offshore industry and other applications within the shipping and dredging industry for many years. The market for fairground attractions is also interesting for us, given the heavy demands. Complex machined welding constructions, assemblies, sub-assemblies and complete products are part of our program.

For this market we work according to customer (mechanical) specifications. Our scope includes parts in single pieces, series as well as assembled products.

Carbon steel & various exotic alloys

We process low-alloy and high-alloy carbon steel, fine-grained steel, stainless steel (various alloys), aluminum, cupronickel 90/10 and 70/30, alu bronze, monel, inconel, weldox, duplex, super duplex and Outokumpu 1.4835 (253MA). We can handle workpieces up to 40 (m)tons in our workshop.

Platforms for (nuclear) power plants

We manufacture major components  like platforms for industrial installations in aggressive environments. Materials applied are stainless steel and duplex.

Containers for industrial applications

We manufacture major components like custom designed containers for industrial installations. Materials applied are stainless steel and duplex.

Components for steel production plants

We supply heat-resistant hoods applied in heat treatment processes in steel production plants (material Outokumpu 1.4835 -253MA).

Hoisting installations – piplay vessels

We manufacture major components for pipelay vessels, used to construct submarine pipelines.

Hoisting installations – heavy lift vessels

We manufacture also hoisting booms for heavy lift vessels like floating sheerlegs with a crane.

Hoisting installations – knuckle beams

Hoisting installations also have many critical components. Hubert, for example, supplies knuckle beams for cranes. These products are also thoroughly tested before they are put into operation.

Hoisting installations – beams

Crane components like hoisting beams are also provided with adjacent constructions like platforms and stairs.

Hoisting installations – pedestal

We manufacture substructures for cranes on ships like pedestals.

Hoisting installations – NDT tests

Crane components like hoisting beams are tested according international standards, including Non-Destructive Testing (NDT).

Components for leisure attractions

We supply critical components for fairground attractions. These products must also meet stringent requirements.

Project: Replacement of gutter and clearing bridge settling tank at WWTP Birdaard

The elaboration of the drawings with accompanying calculations in the preparation phase were well worked out. The construction of the new gutter and bridge was installed satisfactorily by employees and especially the foreman. The project was completed on time, both financially and in the delivery of product certificates and revision. A great project and end result was achieved through synergy between client and contractor.
