High-Spec Steel Assemblies

Complex machined & welded constructions, (sub) assemblies & complete products

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

Hubert has 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 Hubert given the heavy demands. Complex machined welding constructions, (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. Visit also our Dutch website staalbouwhubert.nl

Customer Stories

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.
