The construction of cold rooms requires quality materials.
Cold room panels are insulated self-supporting structural elements used in areas that require controlled temperature conditions, such as food preservation or freezing, in compliance with modern regulations – HACCP.
They consist of two pre-painted metal sheets with a polyurethane core between them.
The outer side of the panel can feature a light profile, micro-ribbing, or embossed/stucco texture.
The inner side of the panel can feature a light profile or a flat finish.
They connect via a male-female joint (interlocking system), feature a sealing gasket, and ensure uniform surfaces with an excellent aesthetic result, facilitating the easy application of all specified sealing materials, such as silicone or mastic.
The manufactured thicknesses are: 80 – 100 – 120 – 150 – 180, and 200 mm.
The 25 mm thickness is available with visible fixings only. Useful width: 1000 mm
Available in lengths from 2.00 to 14.00 m.

PLASTICIZED (PVC) STEEL SHEETS
Galvanizing Method
Hot-dip, with galvanizing weight of at least 150gr/m2 according to the SENDZIMIR method and FePo 2G, UNI5753-84, ASTM A 526 specifications on both sides of each sheet.
Lamination/Plasticization Specifications
Antimagnetic, non-toxic, anti-fungal lamination with a single layer of PVC, 120 microns thick for the outer exposed surface, and an epoxy-based primer, 8–10 microns thick for polyurethane adhesion on the inner side. It is exceptionally resistant to impact stress during product handling within the area, as well as to cleaning with harsh alkali-based detergents.
Classic Polyester Coating
Polyester coatings are the most widespread, common, and economical sheet coatings. They are suitable for both exterior and interior surfaces. With a nominal coating thickness of > 20μm, they offer very good resistance to outdoor environmental conditions.
Hygienic PVC Coating
PVC coating is suitable for food-grade constructions where the metal sheets may come into contact with food. The coating is white with a smooth texture. The coating has a nominal thickness of 120μm and provides excellent antimicrobial protection.
Durable Plastisol Coating
Plastisol coating is exceptionally resistant to outdoor weather conditions. It belongs to the category of "self-healing" coatings against mechanical damage. With a nominal coating thickness of 200μm, it is suitable for exterior applications where durability requirements are high.
Coating Color Options
An extremely wide range of coating color options is available. Please ask us for available colors (RAL 1014 to RAL 9010).

Refrigeration panels are a structural element for the construction of:
Refrigerators / Cold stores.
Cold rooms / Walk-in freezers.
Food production and processing areas.
Clean rooms.
Sterilization rooms.
As well as for the construction of interior and exterior walls.
They are used in areas where controlled temperature and humidity conditions are required.
