POWDER COATING

POWDER COATING is a high aesthetic value anti-corrosive treatment that creates a smooth and homogeneous film on the surface of steel products, commonly known as iron and metal structural work.

USEFUL DIMENSIONS: 13.000 x 2.500 x 1.600mm / 13.000 x 2.800 x 200mm

MAXIMUM WEIGHT: 2.000 kg

Speed of execution

POWDER PAINTING is quickly performed automatically and, upon completion, does not require additional drying time: the elements can be immediately packaged, shipped or assembled.

Certain timing in all weather conditions

POWDER COATING is performed on industrial plant systems that are not affected by weather conditions.

Solvent and VOC-free

The POWDER COATING process is solvent-free.

Even thickness

POWDER COATING allows you to achieve a film with an even thickness over the entire element, unlike the liquid coating which is directly proportional to the expertise of the operator and the application environment.

Architectural Paints

The paints used are designed to withstand atmospheric agents and UV rays, the main cause of fading colours. Cycles can be fine-tuned for special applications according to their intended use.

Guaranteed paint adherence

The secret of the paint adhesion lies in the pre-treatment. In the POWDER COATING system installations pre-treatments are constantly monitored and performed automatically. Something that can not easily take place in manual mode and on worksites.

What is it for

Unprotected steel degrades rapidly showing the formation of corrosion and/or rust. POWDER COATING allows you to create an organic film on the surface of the element which can serve as a corrosion barrier as well as an aesthetic finish.
POWDER-COATING allows you to:

Protect steel against rust
Preserve the structural characteristics of the metal elements
Achieve maximum aesthetic performance
Achieve the best possible inclusion of the work within the installation context by using the most appropriate colours
Preserve the environment and non-renewable resources

Where you can use it

POWDER COATING can be applied to all manufactured products made of carbon steel, commonly called "iron", aluminium, sendzimir metal sheets and pre-galvanised elements with maximum dimensions of 13,000x2,800x200mm, or 13,000x2,500x1,600mm and a maximum weight of 2,000 kg/piece.
POWDER COATING can be used in all environments: indoors, natural areas, urban areas and industrial areas. Special versions are designed for use in marine and off-shore environments or for heavy industrial uses.
Some of the most common elements treated are: gates, fences, railings, beams, roofing structures, storey buildings, pergolas, gazebos, as well as finished products such as lamp posts, litter bin posts and street furniture. View some application examples in the section Projects.

What does it consist of

POWDER COATING is carried out on an industrial plant system that allows monitoring of repeatability and therefore the quality of the film of paint that is created on the element. It differs from liquid coating given the perfect homogeneity of the thickness and the colour of the painted film. It is VOC-free (solvents) representing an excellent sustainable choice.

What is the life expectancy of the powder coating

POWDER COATING allows you to achieve excellent life expectancy.
It is necessary to distinguish corrosion performance from aesthetic performance.
POWDER COATING can achieve a life expectancy of from 2 to 7 years, from 7 to 15 years and over 15 years according to the different environments in which it is used (indoors, natural, urban, industrial, marine).

Description of the main treatment phases

The coating is performed based on a qualified process (according to the requirements of UNI EN ISO 12944 "Corrosion protection of steel structures by protective paint systems") consisting in the following phases:

MECHANICAL PREPARATION of the surface of the element by sanding with fine-grain abrasives, aimed at levelling off and uneven areas on the surface of the zinc coating.
ALKALINE DEGREASING and surface etching, at a temperature of 50°C, to ensure contaminants such as oils and fats are removed.
WASHINGwith mains water to remove residues of the previous treatment.
DEMI RINSE, rinse using demineralised water.
SURFACE CONVERSION with a nano-ceramic process, a treatment that allows you to create a very stable and compact inorganic layer to guarantee high performance paint adhesion.
DEMI RINSE,final rinse using demineralised water.
DRYING in a hot air oven at a temperature of 140-150°C.
POWDER APPLICATION: this phase foresees the actual application of the powder coating (in the required colour) by means of electro-deposition; it all takes place in an automated cabin with work station for any manual retouching required. There are many different types of powders used: epoxy, epoxy-polyesters and polyesters with the possibility of achieving smooth, textured and embossed finishes; all the powders used are "TGIC free" and specially developed for applications on hot-dip galvanized steel.
POLYMERISATION (Firing): the powder deposition phase is followed by the curing phase in a hot air oven at a temperature of 180-200°C; the material remains in the oven for the time required for the powder to polymerise.
REMOVAL AND CONTROL: removal of the materials from the transport equipment, followed by visual inspections to verify that there are no surface defects visible on the elements; the elements are now ready for the packaging phase.
