Zincatura a spruzzo: more flexibility, longer duration, fewer operational constraints
An efficient and versatile technology for anti-corrosion protection, ideal for both new processes and on-site restoration work.
Advantages compared to hot dip galvanizing
Simple and compact process
It does not require complex systems or a high level of specialization of the workforce.
Greater application flexibility
Electric arc systems can spray zinc, aluminum, copper and brass, expanding operational possibilities.
Speed of execution
The work can be carried out without the waiting times typical of hot-dip galvanizing.
Reduced need for manpower
The operator who carries out the sandblasting can also carry out the galvanisation, optimizing time and resources.
Low energy consumption
The process requires low energy consumption, approximately equal to 10 kWh.
No deformation of the support
Zinc-iron adhesion occurs at approximately 150°C, avoiding deformations on the products.
Low initial investment
An accessible solution that offers high flexibility of use.
Trolleyable systems
They allow restoration interventions directly on site or at the customer's site.
Consume zinc only when necessary
There is no need to keep large quantities of molten zinc in the tank, with obvious economic and energy advantages.
Reduced environmental impact
A spray booth and a filtration system are sufficient, without the use of acids or wastewater management.
Advantages compared to traditional painting
Applicable on many surfaces
The process can be used on iron and, depending on the application needs, also on other media.
Greater safety and lower environmental impact
Reduces the use of chemical products typical of some painting cycles.
Ease of use
It does not require complex mixing of products or preparations typical of multilayer paint systems.
High productivity
Circa 30 kg of zinc allow to cover approximately 45 m²/h of iron surface.
Better adhesion and thermal resistance
The coating offers superior behavior at high temperatures and improved response of the protective system.
Significantly superior durability
Three coats of paint can offer a lifespan of around 7 years; zinc can overcome the 25 years of protection.
presence of winds and mechanical wear phenomena
Applying paint on zinc and/or aluminium, corrosion protection can exceed 35–50 years.
Precision, aesthetic performance and versatility
- Zinc deposition from 30 a 500 micron
- Pure and porous zinc coatings
- Ideal surface for sealants and subsequent painting
- Greater enhancement of the details and decorations of the artefact
- Absence of the typical slag and ash of hot galvanizing
An efficient solution to protect, restore and enhance
Spray galvanizing combines operational speed, containment of consumption, reduced environmental impact and long-lasting protection. It is a technology particularly suitable when flexibility is needed, on-site interventions and a better aesthetic result of the product.
