Straatman Dredging & Construction is a specialist in coatings for the offshore and maritime sector. Preserving, painting, post-treating, protecting, or coating: These are all terms used for protecting (steel) products from external influences. Influences that damage the base material of constructions by causing corrosion and rust. Our coating work ensures your steelwork with a weather-resistant protective layer.
Wet painting, powder coating, and galvanizing
We provide coatings in our own workshop using wet paint systems and powder coat systems. With the help of our blasting cabin, conditioned wet paint cabin, and powder coat installation, we can take care of all finishes for your company. Also in accordance with the requirements of the maritime industry (ISO8503). In collaboration with our strategic partners, we also offer the possibility for electrolytic or thermal galvanizing.


Preparation is the key
At Straatman Dredging and Construction, we know better than anyone how construction parts need to be prepared, produced, deburred, and ground for a good coating. The quality of our coating, therefore, already starts at the sawing and drilling department, where literally every part of the construction is deburred and provided with the correct radius to guarantee good adhesion. Special parts are also blasted. At Straatman, we know better than anyone how construction parts need to be prepared, produced, deburred, and ground for a good coating. We can also carry out the preparation according to the ISO8503 standard.
Wet painting
Straatman Dredging & Construction provides your final product with wet paint in our special conditioned wet paint cabin. As the name suggests, wet painting is a coating technique where the paint layers are applied wet on wet. For optimal protection, this is always done in multiple layers, according to a so-called multi-layer system. Also, for protection standards that are mandatory for extreme weather conditions in the maritime sector. Many of our clients come from the maritime sector. That is why we mainly apply wet painting in accordance with the ISO12944 standard up to the highest category: C5M (marine). For the 3-layer systems for this application, only high-quality paint systems from Hempel and International are used.


Powder coating
We use high-quality powders for our powder coatings, which meet the requirements of the construction industry. This is due to their excellent weather resistance and mechanical properties. Depending on the application, we select the powders, the number of layers, and the layer thicknesses. Just like wet painting, finishing with a powder coat is also possible in any RAL color.
We specialize in various powder coating systems. Ranging from single-layer systems for steel to multi-layer systems, for example, aluminum. We can even make a distinction between applications for outdoor or indoor use. Straatman Dredging & Construction has powders in stock for various applications. This varies from powders based on epoxy resins to polyester resins and even combinations thereof.
The most extensive, or best protective variant, is a so-called duplex system, in which steel parts are first galvanized and then powder-coated. This is applied to products that are exposed to extreme weather conditions or are placed in a maritime climate.
