Technical Data

SYMONITE® is an Australian manufactured composite panel, produced exclusively by Symonite Australia Pty Ltd. It is suitable for curtain walling and cladding, fascias, columns, furniture, signage, soffits, spandrels, balustrades etc or wherever a non-flammable, strong, lightweight panel is required.

Standard Panels

Thickness:	4mm and 6mm - other thicknesses available
Width:	1220mm - can be cut to size
Lengths:	1850mm, 2150mm, 2500mm, 2850mm

Standard SYMONITE is manufactured with 0.5mm aluminium faces; the exterior face is coil coated with PVF2 (PVFD), the interior face is normally mill finish. Other sizes, thicknesses and finishes may be available on request.

Core
The core is a fully cured fibre reinforced Phenolic Resin bonded under heat and pressure to the outside metal faces.

THE ADVANTAGES OF SYMONITES' CORE

The advantages of SYMONITE over other composite panels available to building professionals stem from its unique thermosetting core construction.

Extreme Impact Resistance makes SYMONITE a suitable building element where compartmentalisation of fire is an important aspect in fire safety engineering and design.

High Degrees of Stiffness and Rigidity reduces facade engineering and construction costs through superior wind loading characteristics.

High Temperature Stability prevents creep and telegraphic deformation of the external face of the panel on high ambient or high surface temperature conditions because the core does not soften.

UV Stability means that the panel edges can be fully exposed to the elements thus introducing design and fabrication options and also reducing fabrication and installation costs.

Homogenous Thermal Expansion means no differential thermal expansion between the panel's aluminium skin and its core, thus ensuring panel flatness over a wide temperature range.
