Buying Guide

Choose the right alloy

304 stainless is corrosion-resistant and versatile for indoor and mild outdoor use; consider 316 for harsher, chloride-prone environments

Match diameter to application

Select a rod diameter that meets your strength and fit requirements—thicker diameters are stronger but heavier and may require different tooling

Consider length and cut options

Longer stock (24–72 in) reduces the need for joins, while shorter lengths save material and are easier to handle

Check finish and temper

Mill finish is economical and machinable, while annealed rods are softer and easier to work for forming and threading

Plan for machining and welding

Confirm the rod’s machinability and weldability for your process; 304 machines and welds well with appropriate tooling and filler metals
