500 Vs. 550 Filling in the Difference

  •   Posted on June 30, 2021

Minor changes can make a big difference, especially when it come to railing. With Superior offering different modifications and designs, what exactly makes these two variations the same and different?

As we explored previously when we investigated the small yet significant differences in 9000 and 9100 series railing, small changes can a big difference. Today, let’s dive into another series of railing that can cause some confusion because of the subtle yet significant differences. Join us as we take a look at what exactly separates Superior Aluminum Series 500 and Series 550 pipe railings.

What’s the Same?

500 and 550 railing can be seen as brothers of sorts, with similarities between the two mostly obvious. For starters, both products are built with the same 1-1/2” Schedule 40 aluminum pipe and are designed to meet various OSHA, ADA, and ICC safety requirements. The railing styles each utilize the same concealed fastener design, eschewing welding for clean lines and a mechanical finish. These similarities between 500 and 550 are pretty straight forward and easy to see, though just like brothers, there are differences between the two that make them unique in their own way.

What’s Different?

When looking at side by side at the two products, the difference between the two is just as stark as the similarities. Series 550 railing utilizes pickets to fill the vertical space whereas its series 500 counterpart does not, instead opting for much more negative space and horizontal pipe as needed, sometimes featuring nothing more than a single line of pipe. Each product’s design represents a stark contrast in applicable uses. Series 550 Pipe Picket railing can be used as a guardrail in commercial, residential, educational, and more applications. Meanwhile, Series 500 Pipe Railing is often used more as a handrail or on more industrial sites where guardrail requirements are less strict such as a water treatment plant. In an interesting twist these two products can team up to make an excellent pair! By utilizing pipe picket railing as a guardrail on steps or ramps and mounting pipe assist rail to said guardrail you create a code compliant juggernaut of style and function.
