With a minimum of 10% chromium content, stainless steel is known for corrosion resistance. It's typically not as strong as steel and can be more difficult to machine.

Commonly called red metals, each of these alloys has a high copper content that provides good weather resistance. They're also excellent conductors of heat and electricity.

Build linkages for push/pull and oscillating movement by fastening rod ends, swivel joints, or ball joint linkages to the ends of these rods.

Create strong structures by welding this framing together. Add metal panels to close off openings.
