Open Cell Ceiling System
False ceiling composed of open grid, made of aluminium, normal thickness 0.5mm (or as client request). The height is 35mm, 40mm, 45mm, 50mm, 60mm, 70mm & 80mm. The standard colour is white and also can refer to our colour table or RAL codes.
Open grid ceilings are built using easy to join square rod profiles, which it is possible to obtain meshes.
50mm x 50mm, 75mm x 75mm, 100mm x 100mm, 110mm x 110mm, 120mm x 120mm, 125mm x 125mm, 200mm x 200mm & 250mm x 250mm. This grid can be perforated on request. Also available Pyramid grid ceiling as per client request.
Suspension for Open Ceiling system:
- Wire hanger: Galvanized steel wire 2.5mm, 3mm and 4mm diameter.
- Adjustment clips: 0.6mm spring steel fixed to wire hanger.
- Edge trim: 0.5mm Aluminium stove enameled edging at right angles to the panels 15x30x15mm in 4m length or any one of our latest design.
Suspension Technical specifications
Rock Wool Backing can be placed on top of the perforated panels to achieve a high coefficient of absorption (refer to perforated system section for different designated shape). These Metal Ceilings are classified non combustible fire proof class 0, aseptic, humidity - proof, bacterium - proof, corrosion - proof, not dangerous for the health.
Zinc coated carbon - steel wire ASTM A641 / A641M, Class 1 zinc coating, Soft temper. Recommended diameter 3mm so its stress at 3 tines the hanger design load (ASTM C635, Table 1 Direct Hung) will be less that yield stress of wire.
Strips are manufactured from carbon steel strip of ASTM SE 1070 and zinc plated to ASTM B 633-98.
Manufactured from galvanized mild steel strip to ASTM LFQA527.
Main Runner member were tested according to ASTM C 635 - 97 for load-carrying capabilities and didn't exceed the maximum allowable deflection equal 1/360 of its span.
Steel hot-dip galvanized, between Z180 & Z 220
ASTM A366-A366 M
ASTM A366-A366 M
BS EN 10143: 1993
Fire rating :
Suspension system member are tested for fire performance in compliance with ASTM-E119. Classified "0".
Squared or beveled
A black felt is applied to the back of every single perforated panel. The black f supplied already fixed to the panel. The black felt has extremely powerful noise absorption f erties, doesn't release noxious fibers into the air and doesn't decompose over time.
Thermal insulation can be achieved with the application of absorbing pads or insulating materials which can be selected on the market for the specific applications.
Fire performance & hygiene
These Metal Ceilings are classified non combustible fire proof class 0, aseptic, hun - proof, bacterium - proof, corrosion - proof, not dangerous for the health. The coating ii subject to any toxicological classification or identification requirements.
Noise Reduction Coefficient (NRC)
Tested as per ASTM E 795 and the result was over 90% for standard white plain tile over 80% for standard white perforated tile.
Light Reflection Coefficient (LR)
The brighter the color, the more light it reflects, standard ceiling finished in white 9003 or RAL 9010 was Tested and the result was over 85% for plain panels and over 75( perforated panels. Measured in accordance with ASTM 1477 - 98.
Metal LX panels with a degree of gloss upto 22%. can be provided opon request.
Ceiling Attenuation Class (CAC)
Tested and proved over 45 %.
