Atlantic sea proof steel
Design furniture from Joma is designed for use in challenging and harsh environments.
All steel components are Joma Marine™ treated and come with a lifetime warranty against rust.
This process was developed to ensure a high-quality finish that complies with the strict requirements of Corrosion Class C5-M (EN ISO 12944), which enables our products to remain outdoors for several decades. All screws and fastenings are supplied in stainless steel.
First, comprehensive cleaning and pre-treatment, involving many stages, are carried out. Components are dipped in a series of immersion tanks, filled with degreasing agents, purified water and activators. Then, it’s time for the cathodic electrodeposition, which consists of a process of immersion painting, based on the displacement of charged particles within an electric field (paint tank) towards the opposite sign pole (metal part to be painted). So, by applying an electric potential difference, the paint molecules are deposited on the piece (cathode) evenly. This process produces an antioxidant coating that allows our products to remain outdoors for several decades. It is carried out in accordance with the strict specific environmental requirements in ISO 12944.
El recubrimiento en polvo es completamente libre de disolventes y se aplica electrostáticamente a través de boquillas automáticas. El polvo se polimeriza en un horno automatizado para dar al producto su aspecto final y garantía.
The powder coating is completely solvent-free and is applied electrostatically through advanced nozzles. The powder is then melted in an automated curing oven to give the product its final appearance and warranty. This process was developed to ensure a high-quality finish that complies with the strict requirements of Corrosion Class C5-M (EN ISO 12944). This treatment far exceeds the corrosion tests Saline Fog Chamber (UNE-EN ISO 9227) and the European Standard UNE EN 13724.
