Palazzo dei Cristalli
Milan, Italy
The restoration project for the metal structure of the Palazzo dei Cristalli at Parco Lambretta in Milan represents a high-standard intervention in industrial surface treatment and anti-corrosion protection carried out by FES Global Group.
The structure, a central element of the urban regeneration of the former Innocenti‑Maserati industrial complex, covers approximately 39,000 sqm of metalwork and required a comprehensive, technically precise treatment cycle fully compliant with international standards.
Through a methodical and certified approach, FES executed a full cycle of surface preparation, treatment, and finishing, ensuring long-lasting durability and an aesthetic result aligned with the architectural vision.
Project phases
1. Surface preparation
All metal surfaces were prepared through SA1 shot blasting according to ISO 8501‑1, achieving a medium surface roughness in line with international standards, ensuring optimal adhesion for subsequent coatings.
2. Depowdering
After blasting, all elements underwent thorough depowdering, removing any residual particles and preparing surfaces for treatment.
3. Stripe coating of edges and corner
All corners, edges, and junctions were protected with epoxy primer applied by brush and roller (stripe coating), ensuring uniform protection in critical areas.
4. Epoxy primer application
The entire metalwork was treated with spray-applied epoxy primer, creating a continuous anti-corrosion protective layer.
5. Sealing of joints and assemblies
All metal joints and connections were sealed using a overpaintable polyurethane polymer, ensuring stable, long-lasting bonding of surfaces.
5. Polyurethane acrylic topcoat finish
Finally, a polyurethane acrylic finish applied by airless spraying completed the cycle with a high-quality protective coating.
Our services
Mechanical cleaning of surfaces using compressed-air abrasives to remove rust, scale, old paint, and impurities, creating a rough profile optimal for coating adhesion.
Applied treatments prevent material degradation caused by chemical and atmospheric agents. These protective coatings extend the life and functionality of steel surfaces, forming a barrier against oxidation and aggressive substances.
