Stringers are shaped like an upside-down letter "F" and enclose all Rampit USA ramps and platforms. On platforms, two of the four stringers are usually flipped upside-down to create a smooth transition on and off the platform. Platform stringers are cut at 45-degree angles, whereas ramp stringers are cut at 90-degree angles. Stringers are sold individually and cut to the length specified. For a matching set, please add two of the same size to your cart.

All Rampit USA aluminum ramps and platforms are assembled using a series of inter-connected pieces of light and/or medium tread. Medium tread is sold by the foot and comes standard in all Rampit USA ramps and commercial platforms. Please note: there are two different types of medium tread in all Rampit USA ramp sections. The first piece of tread is open on the front and the back and is known as starter tread. All remaining tread on a ramp section is standard medium tread, which is open on the front but closed on the back. When ordering, please select the type of tread, the length needed, and the quantity. For standard platform tread, please see light tread. Please contact us for custom lengths not listed below.
