Alro Steel was established in 1948 by Al and Robert Glick and has grown to include Alro Plastics, Alro Industrial Supply and Alro Metals Outlet.

Metals Processing Capabilities


Thermal Processing

Stress Relieving diminishes the residual stress in steel caused by working the material (i.e. flame cutting, forming, rolling, casting, machining, welding, bending, straightening). This is accomplished by reheating the steel then cooling it at a slower rate.

Normalizing is accomplished by heating the metal above the transformation temperature, then cooling it in still or slightly agitated air.

Annealing is accomplished by heating the metal just below the transformation temperature, then cooling in a controlled cycle which limits the cooling rate and brings the temperature down slowly.
