Thermal Metal Spraying
Thermal metal spraying is a process for applying metallic coatings by melting a wire feedstock (zinc, aluminium, copper, brass or bronze) and spraying it onto a previously blast-cleaned surface. The molten metal is atomised using compressed air and projected at high velocity, forming a continuous, well-bonded coating with outstanding corrosion resistance. This process is widely used for steel structures, industrial equipment, components exposed to aggressive environments, and applications requiring long-term anti-corrosion protection.
At METALIZAREAL, this process is carried out in a large-scale thermal spraying booth equipped with an industrial dust extraction system and designed to accommodate 4 metal spraying operators working simultaneously, ensuring high productivity and stringent quality control. The main features of the facility include:
– Booth dimensions: 30.00 m (length) × 10.00 m (width) × 6.00 m (height)
– Simultaneous operation: capacity for 4 metal spraying operators working at the same time, enabling high production throughput
– Material compatibility: wire feedstock in zinc, aluminium, copper, brass and bronze, selected according to project requirements
– Dust extraction system: continuous extraction of fumes and airborne particles, ensuring excellent visibility, operator safety and a clean working environment
– Process control: precise adjustment of melting temperature, air flow and deposition rate to achieve uniform coating thickness
– High-durability coatings: capable of applying metallic coatings with excellent adhesion and outstanding mechanical performance
Thermal metal spraying produces coatings with exceptional performance in C4, C5 and CX corrosivity environments, in accordance with ISO 12944, making it an ideal solution for structures exposed to industrial, marine or highly corrosive atmospheres. The process also offers the significant advantage of introducing minimal thermal stress into the substrate, allowing large fabrications and complex components to be treated without the risk of distortion.
The combination of advanced spraying technology, highly skilled operators and rigorous process control enables METALIZAREAL to deliver metallic coatings of exceptional quality, uniformity and long-term durability.
