Quality and precision are at the heart of our approach to steel structures. We are NEN-EN 1090-1 certified: our structures demonstrably meet high quality requirements.
The process starts with an accurate survey of the site, after which we prepare the structural drawing. This drawing contains all the exact dimensions and specifications of the materials required, so nothing is left to chance.
Once the drawing has been approved, we order the materials required and start production. We use only high-grade structural steel to EN 10025. Our profiles are manufactured to strict DIN standards and the steel tubes are of welded construction. As standard, we use hot-dip galvanised fasteners that meet property class 8.8.
Depending on your requirements, we can finish the structure in various ways. We can hot-dip galvanise the structure (to NEN-EN-ISO 1461), finish it with a powder coating or spray it in a RAL colour of your choice. The coating is applied in several layers, including an epoxy zinc phosphate primer and a high-gloss polyurethane topcoat, providing optimum protection and an attractive finish.
You can read exactly what NEN-EN 1090 certification involves and how we work to the standard on the page NEN-EN 1090.
Would you like us to handle installation on site as well? No problem. Our skilled installers will be happy to take care of it, so you have nothing to worry about.
For BAM Bouw en Techniek, we made the cage structures for the service shafts of this eleven-storey building, with grating floors on every level. In the atrium, we finished the edges of the voids with white sheet metal, with 67,000 holes per panel for better acoustics.

At the end of 2019, NS and ProRail replaced the familiar split-flap board in station concourses with a large digital passenger information display: a single screen showing the departure times for the next half hour at a glance, plus travel advice during disruptions. Utrecht Centraal, Den Haag Centraal and Rotterdam Centraal were among the stations to get one of these new displays.
Streetfurniture supplied the displays on behalf of NS and ProRail; we made the steel housings and supporting structures of this new model for them. Every station has its own size and its own position in the concourse, so every display is custom-made.

For many years, we have been making steelwork for public spaces for Streetfurniture, from one-offs to complete series. One example is the housings and structures for the new NS and ProRail passenger information displays, the digital successor to the split-flap board.
For Carrier, we make modular frames that make large cooling and heating units mobile for rental. The frames carry heavy machines and are moved and transported again and again. Safety and strength calculations therefore come first.
For many years, we have been producing sheet metal and bending work, drawings and structures for Van den Akker Metaaltechniek. These are often series of tens to hundreds of parts, which we produce from a drawing or sketch.
Besides large projects, we make parts and steelwork for many companies, as one-off orders or in series.
