Technical Information
  AICKINSTRUT FABRICATION
The installation of fiberglass channel and accessories is similar to the installation of metallic channel and accessories. All standard installation practices and procedures apply. In general, special handling is not required. Fabrication of Aickinstrut components requires just three simple operations; cutting, drilling and sealing as described below.
Cutting – Cutting can be accomplished with a wide variety of saws. Hand held saws, such as hack saws (24 to 32 teeth per inch) are suitable when a few number of cuts are required. For frequent cutting, a circular power saw with a carbide-tipped masonry blade yields the best results and the greatest number of cuts. When using a power saw, dust filter masks, gloves and long sleeve clothing should be worn.
Drilling – Any standard twist bit, even when used with battery-powered drills will work well. Carbide-tipped drill bits are recommended.
LABOR SAVINGS
Aickinstrut fiberglass structural members can be cut and drilled at a much faster rate than steel. Typically, fiberglass can be fabricated in less than half the time. As a result, substantial labor savings will be realized. Also, Aickinstrut products average 1⁄3 the weight of their steel counterparts, making them much easier to handle on the job site.
RELATIVE MATERIAL COSTS
Aickinstrut materials are advantageously priced relative
to specialty metals traditionally used in corrosive environ- ments. Aickinstrut, even though slightly more expensive than pre-galvanized channel, can be used with the knowledge that it will not have to be maintained regularly or replaced after a brief time. Should pre-galvanized chan- nel have to be replaced once, its cost far outweighs the expense of doing the initial installation with Aickinstrut.
MATERIAL
The finished Aickinstrut application will utilize a combination of materials from the following resin families:
these criteria, you will be able to select the optimal Aickinstrut Channel, Fittings and Accessories for your particular applications.
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:
• Temperature
• Chemical Environment • 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.
Material Low High Code Temperature Temperature
 E -25°F P -35°F V -35°F
PU -40°F PP -30°F N -20°F
130°F 200°F 200°F
140°F 150°F 150°F
  Material Code

PU PP N
Material
PVC (extruded) Polyester (pultruded) Vinyl ester (pultruded)
Polyurethane (injection molded) Polypropylene (injection molded) Nylon (injection molded)
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 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 13 to 15. Additional loading and design limitations for fittings and accessories are described in the appropriate section for that part.
   The ability of each material to handle high and low temperatures, chemical exposures and static loads is covered in each of the following sections. By using
