The Steel Supply Company was founded as a specialty warehouse to supply ground and polished precision shafting. Today we are an international distributor operating from two locations. Our warehouse in Rolling Meadows, Illinois, stocks 4,000 individual sizes and grades of steel tubing and steel shafting.

Our in-house machine shop produces hydraulic rods and piston rods and cylinder barrels and is equipped for most types of general machining as well.Our second location, in Fox Lake, Illinois, is a complete source of chrome-plated shafting and tubing for the hydraulic industry and fills quantity orders at mill prices.Our manufacturing innovations and technical procedures are recognized by registered trademarks such as Electreat 50™, #2 Chrome Piston Steel™, and Hi-Yield™ Precision Shafting.

Steel Fabrication Services

• We provide the hydraulic industry with hard chrome plating for an extremely hard, long-wearing surface coupled with a very low coefficient of friction. Sizes from 1/8- inch diameter to 12-inch diameter and lengths to 32 feet can be produced.
• Induction hardening produces a very hard outer surface that can resist the damage which would destroy an unhardened rod.
• Our modern equipment produces the size, tolerances and roundness necessary for quality hydraulic and air cylinders.
• Centerless grinding of cold drawn or turned bars provides the size, tolerance and roundness necessary for piston rod stock.
• Special items, non-standard sizes, tolerances and chrome thicknesses can be quickly produced at our production facilities.
• Our in-house machine shop specializes in prototype work as well as production quantities. We produce hydraulic piston rods, cylinder barrels, blower shafts, power transmission shafts, rolls and pivot pins. We also have all the equipment needed to produce general job shop machined items.
