| Clickfix Aluminium Coping - Performance Wind resistance
Clickfix copings have been satisfactorily used in many locations, but in very exposed locations it may be preferable to use the Alifabs Architectural coping. It is essential that copings are properly fixed to enable them to meet design performance. Resistance to chemicals
Not affected by normal industrial atmospheres. Consult Alifabs before using in conditions of extreme atmospheric pollution or in coastal areas. Thermal movement
Coefficient of linear thermal expansion is 23 x l0:6 per deg C. A gap of 2 to 3mm left between coping sections will accommodate normal thermal movement. Lightning protection
Lightning conductor linkages can be supplied to provide electrical continuity between lengths of coping. Compatibility
Fixing straps can have a coat of zinc chromate primerto the underside, if necessary, to protect from direct contact with materials which might cause electrolytic action. Durability
Aluminium is inherently resistant to corrosion due to the formation of a natural oxide film on the surface. In normal atmospheric conditions the coping has a life expectancy in excess of 40 years. |
