Steelwork painting restoration
Munich, Germany
The intervention forms part of a major industrial construction project involving steel structures intended for roofing systems of production facilities.
In this steelwork restoration and painting intervention, the structures—composed of trusses assembled on site—had already been coated at an earlier stage and subsequently handled, transported, and installed at height.
Following installation operations and on-site welding activities, widespread defects were identified in the protective coating, making a specialised restoration intervention necessary.
Goals of the intervention:
To restore the integrity of the protective coating system on the steel structures, ensuring:
- continuity of the coating system
- uniform dry film thickness
- compliant anti-corrosion protection according to project specifications (120 µm)
- correction of post-installation defects
Phases of the intervention
1. Initial inspection and assessment
Visual analysis of the coated surfaces aimed at identifying defects, damage, and issues affecting the existing protective system.
2. Environmental condition monitoring
Measurement of environmental parameters, including temperature and dew point, to verify the suitability of application conditions prior to the intervention.
3. Protection of surrounding areas
Application of masking and protective systems to safeguard areas not involved in the works.
4. Surface preparation
Localised sanding, removal of discontinuities, and technical cleaning to ensure proper adhesion of the new protective coating system.
5. Restoration of the coating system
Execution of touch-up and restoration works through manual application of the coating, ensuring uniformity of the protective film.
6. Thickness and quality control
Verification of dry film thickness and inspection of correct application in compliance with the required technical specifications.

Specialist technical consultancy services in the field of surface treatments, supporting clients in inspection, verification, and optimisation of application systems. This approach ensures compliance, quality, and durability of interventions across all application contexts.
Anti-corrosion treatments are designed to prevent the degradation of materials, particularly metals, caused by interaction with chemical and atmospheric agents. Special anti-corrosion protection systems extend the service life and functionality of surfaces by creating a barrier against oxidation and the attack of aggressive substances.
Results
The steelwork restoration and painting intervention made it possible to:
- restore continuity of the protective coating system
- bring the surfaces back to the required performance levels
- ensure coating thickness compliance with project specifications
- improve the aesthetic and functional uniformity of the structures
The works were carried out in accordance with on-site operating conditions and available access windows, ensuring high quality standards even in complex and high-level working environments.
