Technical Information Aickinstrut Fiberglass Framing System
Operating Environment In order to design an Aickinstrut system for your application, consideration should be given to the maximum operating conditions. These “worst case” conditions will determine which type of Aickinstrut materials are best suited for your application. The three “worst case” operating conditions to consider are: ꞏ Temperature ꞏ Chemical Environment ꞏ Loading Temperature Ranges – Aickinstrut is supplied in six different materials covering distinct temperature ranges. Materials should be chosen which meet or exceed the minimum and maximum temperatures for your applications.
The temperature ranges indicated are meant to be used only as a general guideline. Continual exposure to elevated temperatures reduces the strength properties of plastics and glass reinforced fiberglass. Actual resin test data confirms that a 50% reduction in strength occurs at the extreme high temperature levels. Chemical Resistance – Each resin family has its own specifications regarding its performance against corrosion resistance. Use the following chart on pages 222-223 to determine which Aickinstrut material system will provide the best performance for your particular application. The results in the chart are based upon immersion for a 24 hour period. This is typically the “worst case” exposure to corrosion. Less severe contact such as spills, splashes and vapor condensate will exceed the performance results listed in the table. Loading – Channel loading is defined on pages 228 to 230. Additional loading and design limitations for fittings and accessories are described in the appropriate section for that part.
