Steel

Steel is better suited for supporting heavy weights, being almost twice as rigid as brass. This increased rigidity also makes it more difficult to form, and may necessitate specific metal working tools; welding equipment, presses, brakes, and bending tools. Small pieces can be joined together by silver soldering, while larger pieces must be joined by welding or mechanical fastening.

Steel is also heavier than brass, but the increased strength it provides is often the more important factor for use with large, heavy objects.  It can rust, so must be properly sealed before installation.
