EXCEPTIONAL STRENGTH Durable powder-coated aluminum is AAMA certified and rust proof. And with over 10,000 hours of salt-spray testing (used to accelerate corrosion performance of a coating system), Avalon performs at more than 3 times the required standard of 3,000 hours! It exceeds most all commercial and residential codes and is supported with a limited lifetime warranty. If you’re looking for something more, try Avalon with glass slats. Glass slats open up your view from your deck without compromising your safety. SECURATEC™ LOCKING STRIP Patented, innovative locking strip, pre-installed into the top and bottom rails, locks in balusters for a secure fit and eliminates rattling.
