We have a bone to pick with rust and weathering!
CORROSION PROTECTION
Our core expertise. In recent decades, we have processed many millions of square metres of steel and in 2016 we moved and coated the world's heaviest monopile, with a weight of over 1302 tonnes. With our large production halls and our several thousand square metres of storage space, we are able to professionally process any surface. Our complete corrosion protection services can be combined with our heavy duty logistics. This means that no waiting times or delays arise for our customers.
We are able to perform stationary and mobile work for you across Europe:
- Blasting and coating work for conventional and heavy corrosion protection
- Removal and disposal of old coatings contaminated with PAH and asbestos
- Maximum pressure water jets (max. 3,000 bar)
- Interior tank coatings, applied conventionally or using the 2K hot spray process
- Sprayable rubber coatings using ProCoat®
- Thermal spraying of zinc, aluminium and their alloys
- Thermoplastic coatings
- Coatings using Oxifree TM 198
- Powder coatings
- All types of blasting work
- Staining and passivation work
- Labelling work
CORROSION PROTECTION Special coatings
If your conventional corrosion protection is no longer sufficient, we have further special solutions ready for you in the form of coatings. We operate with all corrosion categories (C1 – CX)
Since our work on the wind farm "Arkona Becken Südost" for E.ON, our robotics have also been used since 2017 for coating work on monopiles using thermally coated aluminium.
We developed a robot-supported coating option for this project with our R&D department.
E.ON was therefore the first company in the world to install the monopiles of an offshore wind farm entirely using environmentally friendly corrosion protection technology, thereby setting new standards.
The coating process involves a robot with two arc torches spraying molten aluminium onto the foundation. The process is conducted dust-free for the most part under the highest occupational safety and environmental protection standards. The surface is then sealed.
We are proud to have found another way in which we can significantly reduce environmental influences with this process.
Our patented coating material (e.g., for bridge structures or tank depots) made of recycled car tyres is a solution for a wide range of applications!
- heat insulated
- noise insulated
- high mechanical resistance
- no limitation in the layer thickness
Powder coating is an efficient solution for many steel and aluminium parts that do not need to be coated on site. We offer a cost-optimised solution for almost every requirement, ranging from a purely decorative colour coating to C5+ corrosion protection. The powder coating offers greater mechanical resistance than a conventional wet coating.
Whether large or small – with our modern systems, our competent team and parts dimensions up to 6×2.5×1.9m, we are definitely the right contact for you.
Even if your workpieces require more elaborate pre-treatment, they can be blasted, ground, phosphated, passivated or otherwise pre-treated directly onsite.
In Hamburg, we can guarantee professional coating with the highest quality standards for small and large series or individual parts up to 1,500 kg, as well as a short processing time.
We are also happy to handle all logistics services related to your order. Hanseschicht is your partner for coating.
Thermoplastic coatings
Thermoplastic coating is a special type of powder coating.
Here, thermoplastic material is applied to the hot part and melted onto it. The part must have a rough surface, as the adhesion is purely mechanical.
This means that the plastic remains very elastic, and this method makes it possible to achieve much higher layer thicknesses than when applying regular powder coating. Abcite® is therefore ideal for all areas of application where maximum mechanical, chemical and UV resistance are required as well as maximum corrosion protection and good repair options.
Interior tank coating using hot spray products
Tanks and containers used in the petrochemical sector are inspected by the TÜV or other inspection institutions at regular intervals. We recommend coating the interior of the tank to ensure that your tank or container will pass the acceptance tests in the next few years, and that it is conductive and suitable for use in storing inorganic and/or water-polluting liquids such as acids, alkalis and salt solutions.
As a certified and approved specialist company according to the Water Resources Act (WHG) §19 I, we can apply the respectively approved and tested hot coating materials, in accordance with DIBt [German Institute for Building Technology Berlin], to your tank/container.
For the optimal protection of your tank/container, it is important to consider a wide range of different and at the same time very demanding and complex processing parameters. Starting with the optimal surface preparation, to ensuring and maintaining the best climate parameters in the coating atmosphere, the precise and error-free measurement of the coating material component, to documentation, inspection and acceptance by the TÜV.
Thanks to our modern, environmentally friendly and highly effective machinery, our specialist company can guarantee you fast, safe and efficient processing on your premises, while observing the respective safety standards.
Thermally sprayed zinc and aluminium alloys (TSA) can be used to protect iron and steel structures such as steel buildings and bridges from corrosion. This work can be performed under the concept of metallisation, both in a stationary location and on site, taking into account DIN EN ISO 2063 and specific employee qualifications in accordance with DIN EN ISO 14918.
The coating material, such as zinc or aluminium, is melted or fused with the aid of thermal energy and applied to the surface of the structure by means of dusting.
This coating method results in a solidified coating material which creates a firmly bonded metal layer on the structure, and which is protective for longer than conventional organic corrosion protection systems. Furthermore, the system is able to repair itself to a certain extent. For the customer, this means a longer period between inspections, therefore reducing repair costs.
CORROSION PROTECTION Mobile
With mobile corrosion protection, we bring our proven quality and technology to your location! Our team is continually gaining references in the fields of bridge renovation, tank renovation, lock gate renovation, weir drums and other steel structures. We have prepared a suitable coating for you for each corrosion category.
We use environmentally friendly blasting agent processing (TRGS 519 is fulfilled) with our mobile blasting unit, which means that the processed blasting agent can be used again multiple times and therefore significantly less needs to be disposed of. Old coatings containing hazardous substances can also be blasted in this way.
Thanks to the use of our own logistics, we are independent and extremely flexible in terms of location, time and speed when it comes to your project!
CORROSION PROTECTION Under exertion
Corrosion protection under particular exertion is defined by its environment:
- Working at heights
- Working with hazardous substances
- Protection against radiation
- Tank interiors
Whether on land or at sea, our employees are precisely suited to work in these areas of application due to their qualifications and the results of their occupational health examinations.
When working at heights, our trained personnel (FISAT/IRATA) are not limited by either the climate or the operation site. We have been able to gain experience at all possible kinds of operation sites, such as support structures, gantry cranes, coal power plants, offshore platforms, industrial plants, etc.
Our employees have been trained internally to complete services which can be performed at heights. The following capacities are available for this purpose, at a minimum:
- 10 industrial climbers (Level3 AvO)
- 40 industrial climbers (Level1-2)
Working with hazardous substances
Structures are protected from corrosion for functional and optical reasons against weathering and environmental influences using a wide variety of coating materials. Over the course of time, some coating materials used in the past have now been classified as hazardous, as they can be hazardous to health, carcinogenic or even mutagenic. These materials generally include polycyclic aromatic hydrocarbons (PAHS), organic chloride compounds such as polychlorinated biphenyls (PCBs), asbestos and lead.
If the building belonging to the energy, air, traffic or water industry which needs to renovated contains coatings with one of these hazardous materials, specialists such as the Krebs Group of Companies are required to perform the renovation/repair of the corrosion protection!
As a competent partner, we have the necessary technical and professional expertise, are able to provide a wide variety of coating and exhaust equipment, black, white and monitoring techniques as well as special PPE (personal protective equipment), and are familiar with the respective official requirements of the individual federal states.
Regardless of whether your building should be partially or completely renovated, or if all hazardous coatings should be removed before being scrapped, we are available to provide advice and assistance as your competent partner!
CORROSION PROTECTION Stationary
Our stationary corrosion protection is available at our 4 locations in Hamburg, Wismar, Rostock and Lubmin. Different hall capacities and logistical access result in a wide range of options for your components and requirements.
