Metal spraying in the province of Padua

Anti-corrosion metal coatings  to protect surfaces

Bacchin S.r.l. specialises in industrial metal spraying in Padua, providing professional treatments to protect metal surfaces from corrosion and weathering. With experience dating back to 1980 and specialised equipment, the company applies protective coatings to workpieces, components and industrial structures of various sizes.

Metal spraying is a surface coating process in which metallic materials are applied using thermal spray techniques. The treatment creates a protective layer on the substrate, helping to prevent corrosion and preserve the condition of treated structures over time.

At its facility in Saonara, in the province of Padua, Bacchin applies coatings using zinc, aluminium and zinc-aluminium alloys (85-15%), with coating thicknesses ranging from 50 to 500 microns, depending on specific technical requirements.

Work can be carried out either at the company’s premises or directly at customers’ facilities and on site, making it possible to treat large and heavy workpieces.

Metal spraying with zinc, aluminium and protective alloys

Choosing the coating material is a key part of defining the anti-corrosion treatment. The substrate, exposure environment and operating conditions all influence the choice of the most suitable solution.

Bacchin offers different types of metal spraying, using protective materials selected to suit each project.

The main options include:

• Zinc metal spraying: suitable for protecting steel surfaces against corrosion, thanks to the protective action of the metal coating.
• Aluminium metal spraying: used to create corrosion-resistant coatings, particularly suited to industrial and marine applications.
• 85-15% zinc-aluminium alloy metal spraying: combines the properties of both metals to provide protective coatings for a range of exposure conditions.

Coating thicknesses from 50 to 500 microns make it possible to tailor the treatment to the specified technical requirements, taking into account the workpiece and the planned protection system.

Where specified in the project, metal spraying can also be followed by painting to create multi-layer anti-corrosion protection systems.

The aim is to identify the coating best suited to the structure’s operating conditions, helping improve its corrosion resistance and reduce surface deterioration over time.

Thermal Spray Aluminium (TSA)  and protection in aggressive environments

Among the specialized applications of the industrial metallization in Padua This includes treatments with aluminum through thermal spraying, also known as Thermal Spray Aluminum (TSA).

This technology is used for the anti-corrosion protection of metal surfaces exposed to particularly harsh environmental conditions, such as those found in the marine environment and in certain industrial plants.

The treatment consists of applying an aluminum coating to the appropriately prepared surface, forming a protective layer designed to counteract the action of corrosive agents.

Bacchin is qualified by Shell for TSA (Thermal Spray Aluminium), a distinctive element that demonstrates the skills developed by the company in carrying out this type of specialist treatment.

Proper surface preparation plays a fundamental role in the quality of the result. Before metallization, the substrate undergoes the necessary processes to achieve the surface conditions required by the application cycle.

In this context, industrial sandblasting constitutes an important preparatory phase, as it allows the removal of contaminants, oxidations and pre-existing coatings, promoting the adhesion of the subsequent metallic layer.

The choice of materials, thicknesses and application methods is defined by considering the technical specifications and expected operating conditions.
