Virtually all Sanctum aluminium products are supplied pre-finished and ready to install. The finish of choice for all aluminium products is powder coating – where the finishing coat is applied as a powder to an electrically charged surface, and then baked on for a great looking, robust and protective finish. Powder coating is one of the most durable colour coatings available and, with very little effort on your part, it will provide you with many years of excellent service. To extend the life of powder coated articles and to comply with warranty requirements for powder coated aluminium surfaces, a simple, regular maintenance program should be implemented. The Australian environment is particularly demanding, and harsh sunlight, atmospheric pollution, dirt, grime and airborne contaminants can all accumulate over time and should be removed at regular intervals. As a general guide, your screens and gates should be properly cleaned every three months. In harsh environments and / or areas where pollutants are more prevalent, such as poolside installations, beachfront houses and industrial applications, then a more regular cleaning program is recommended.
