Surface Treatments<\/h2><\/div>

Galvanizing <\/u><\/h3>

Grating for urban furniture solutions adds a modern and original touch to your architectural and landscape design elements. Hot-dip galvanising of steel gratings<\/strong> serves to protect against corrosion. By immersion in a zinc bath at approx. 450\u00b0C, the gratings become corrosion-resistant and more durable.<\/p>

The standard governing the execution of hot-dip galvanising is the Norm DIN EN ISO 1461<\/strong>.<\/p><\/div>

Powder Coating<\/u><\/h3>

A finishing process in which powder paint is applied to the grating and then cured in an oven at 200 \u00b0C<\/b>.<\/p>

Powder coating allows a wide color range and creates uniform, durable finishes on metal gratings (gloss, matte, textured, etc.).<\/p>

Powder coating is in the Architecture<\/a> popular and has an aesthetic, design-oriented side.<\/p><\/div>

\"\"<\/figure><\/div><\/div>

KTL Coating (Cathodic Dip Coating)<\/u><\/h3>

KTL is an industrial coating process that ensures an even paint layer on metal parts.<\/p>

The grating is immersed in a bath of water-based conductive paint and connected as a cathode. Using direct current, pigments migrate to the metal surface, coating the entire immersed part uniformly. The coating is then cured at approx. 180 \u00b0C.<\/p>

KTL is also known as electrophoretic coating<\/b> or cationic electro-dip coating<\/b>.<\/p>

It is widely used in the automotive industry and is also applied in sectors such as aerospace and construction.<\/p><\/div>

Pickling<\/u><\/h3>

Pickling removes impurities through chemical or electrochemical reactions, leaving the surface clean and free of grease and oxide layers. This creates a uniform base surface that ensures good adhesion for subsequent coatings. Benefits include improved corrosion resistance, better surface quality and optimal adhesion of passivation layers or additional coatings.<\/p><\/div>

Passivation <\/u><\/h3>

Passivation is a process that forms a protective layer on the surface of a metal to slow down corrosion. This layer acts as a barrier between the metal and its environment, protecting it from external influences.<\/p>

Passivation not only improves corrosion resistance but also enhances the appearance of gratings.<\/p><\/div>

Anodizing (Anodic Oxidation) <\/u>Anodische Oxidation)<\/u><\/h3>

A specific surface treatment for aluminum.<\/p>

Anodizing forms an oxide layer on the aluminum grating surface (an electrically insulating layer of 5 to 50 micrometers<\/b>).<\/p>

This process increases resistance to wear, corrosion and heat. Colored anodizing in accordance with the EURAS color chart<\/b> is also possible.<\/p><\/div>

Electropolishing <\/u><\/h3>

A specific surface treatment for stainless steel.<\/p>

This process simultaneously polishes and passivates the stainless steel grating.<\/p>

Electropolished (or polished) stainless steel obtains a smooth surface with particularly high corrosion resistance.<\/p>
