The Series Trays is a group of metallic false ceilings that are square or rectangular aluminium or galvanized steel trays installed on conventional visible profiling. The trays are easily detached and registered, ideal for false ceilings with many facilities. Possibility of perforated trays.
Tecnical descriptionExpand all
Ceiling placement in linear or modular system:
Fire Reaction Class A1 Classification of material behaviour in the case of fire in accordance with European law EN 13501-1. Class 1 for slats and trays for false ceilings and wall faces with a lacquered finish with COIL COATING or COIL COATING DI painting systems.
Fire Reaction Class A2 Classification of material behaviour in the case of fire in accordance with European law EN 13501-1. Class 2 for trays for false ceilings and wall faces with a POWDER PAINT electrostatic coating finish.
Capacity Support Profile Class 1: Classification of the load capacity of the support profile of the false ceiling and wall face systems with trays and slats, classified according to their flexion according to the regulation UNE-EN 13964:2000.
Durability Class A: Classification of exposure conditions of materials in false room and wall face systems which are normally exposed to variations in relative humidity of up to 70%, and variations in temperature of up to 25°; they have no corrosive pollutants, in accordance with regulation UNE-EN 13964:2006/A1
Material Aluminum Coils: Aluminium strapping with thickness according to the final product. It comes from an aluminium alloy of 3005 with Temper H-18. The material we use is from the second smelting.
Material Galvanized Coils: Galvanized steel strapping with a thickness according to the final product. It has a steel grade and quality for folding, and has a hot-dipped Zn coating in accordance with regulation UNE- EN 10346.
Acoustic absorption property:
Absorption with a Solid Panel of Mineral Glass Wool: Possibility of increasing the level of a false ceiling’s acoustic absorption with a solid panel of mineral glass wool, or mineral stone wool, with a film or acoustic cover on one of the panel’s faces.
Veil acoustic absorption: Possibility of increasing the level of a false ceiling’s acoustic absorption with a film or a heat-sealed acoustic cover on the inside of the trays or perforated slats. They avoid water condensation by having few thermo-isolating properties, and they ensure continual air circulation.

Lacquered Coil-Coating: Process of continual painting, meeting all ECCA (European Coil Coating Association) rules and regulations. The paint used is polyester-polyamide with thickness of 15-22 microns applied continuously and oven-dried. It is a pre-lacquering system (the process is carried out prior to formatting the tray).
Lacquered Coil-Coating DI: Process of continuous painting in two layers, meeting all ECCA (European Coil Coating Association) rules and regulations. The paint is polyester-polyamide with a thickness of 23-30 microns, meaning that the coating is guaranteed and protects the entire surface corresponding to the edge of the holes which form the perforations in the tray. It is a pre-lacquering system DI (the process is carried out before formatting the tray).
Powder Coating: Electrostatic painting process with power painting, achieving an organic finish of heat-strengthened polyester, guaranteeing an optimal treatment and ensuring that the mechanical and chemical properties of the final result are suitable for the purpose. The thickness of the paint is 60-90 microns depending on the final type of product. It is a post-lacquering system (the process is carried out after formatting the tray).
Recycling material: The false ceiling and wall faces at Gradhermetic Plc meet all the requirements for using recycled material in accordance with regulation UNE-EN ISO 14021:1999. The post-consumption recycled content is 99.2%, reaching 96.8% depending on the product and if it’s perforated or not.
