No matter the application, Simkar provides an assortment of round and square steel poles, tenons and mounting accessories. Simkar’s poles feature materials and finishes resistant to chemicals, corrosion and abrasion which will enhance the pole’s aesthetic appeal and service life. It is important to select pole(s) according to the structural requirement and to suit the specific application. Effective Projected Area (EPA) ratings on page 256 are listed for each pole and cover the full range of available fixtures with various mounting options. EPA ratings take into account a gust factor of 1.3 to ensure adequate wind loading under extreme conditions. EPA is the exposed surface area of both the fixture and the bracket with some variation depending on the shape of the surface. Pole selection should take into account the effect of winds. When placing your order, it is also important to consider the total weight of the fixture(s) to be mounted on each pole. Simply add the total weight of all the fixtures and reference the maximum fixture weight listed on the pole ordering information table for each model as shown below.
