Project-driven and ISO certified construction process

As a project driven organization, Voortman Steel Construction organises the construction process as efficiently as possible. The purpose is to realise the project based on the highest quality within the agreed schedule. The responsible project manager supervises the entire process and involves the appropriate staff and expertise to each project. From production through to delivery on site, all processes are matched seamlessly.


The Voortman Steel Construction calculation department has an important role to play in the process. Our estimators carefully calculate every project. The result: an optimal price/quality ratio for the customer. We calculate with BIM. This allows us to quickly and expertly import, convert, and eventually calculate the IFC model.


With an automated machinery park of sister company Voortman Steel Machinery and our production location in the Netherlands, we have a production capacity of 30000 tons per year. The entire production process is facilitated LEAN and BIM controlled. In short: we guarantee short supply times and low production costs.

To prove the quality of services and products, we are certified for:

  • NEN-EN 1090-1 (CE marking), execution classification EXC4
  • NEN-EN-ISO 9001
  • NEN-EN-ISO 3834-2
  • NEN-EN-ISO 14001

The steel structures are produced with the latest welding techniques under a certified quality assurance system for welding: the NEN-EN-ISO 3834-2. Thus, we meet the requirements for welding co-ordination staff with extensive knowledge (IWE level) of preparations and checks before, during and after welding.

Surface Treatment

Expertise in the field of conservation is of great importance for a qualitative and long-term protection of the steel construction. That is why we work for the surface and anti-corrosion treatments with experienced and reliable partners, who know how to harness steel with the proper treatments. They make use of the latest techniques in order to guarantee a qualitative and long-term protection according to the current environmental requirements.


Every year, many thousands of tonnes of steel leave the Voortman Steel Construction production sites. To make the process as efficient as possible, we also offer transport solutions for the whole of Europe and beyond, if desired. We do this both by land and by sea. We work closely with international transport companies and transport our products in containers, via open transport or covered transport.
