About RSJ.info

Building the future, one beam at a time.

Our Iron-Clad Mission

Welcome to RSJ.info, where heavy metal meets heavy intellect. We aren't just a website; we are the digital load-bearing wall of the construction internet. Born from the sparks of a grinding wheel and the precise calculations of structural genius, we exist to demystify the world of Rolled Steel Joists for builders, architects, and the brave weekend warrior.

Whether you're calculating the load for a grand extension or just trying to figure out why your builder keeps muttering about "universal columns," we've got your back. We believe that structural integrity shouldn't be a mystery, and that every beam deserves its moment to shine (even if it's getting plastered over).
