Stainless Steel Square Bar Presses Offered

Cold Drawn:

Cold drawn is the best way to form square bars because of the concentrated forming required. This process would involve the hot rolled process and then, of course, be further formed into the square form that is required by the client. While cold drawn square bars will be stronger in quality, they are sometimes not n necessary for the task at hand.

Hot Rolled:

For steel sizes in between 3” to 8”, we can offer hot rolled versions of these square bars at the request of the customer. The size and durability of the hot rolled process allow us to have quicker service for those who need square bars.

Note: Orders over 3” are still considered special orders. Make sure to ask about the special order policy when contacting your sales advisor.

Square Bar Metals

For our square bars, we offer stainless steel and nickel alloy.

Stainless Steel Square Bars – We provide stainless steel square bar in 303, 304, 316, and 416. Other grades available on request.

Nickel Alloy Square Bars – We currently offer 14 types of nickel alloy, all of which can be forged into square bars upon the client’s request. The most commonly requested nickel alloy square bar types are 200/200L, 405/405L and 718.

Stainless Steel vs. Nickel Alloy – The choice of beam changes depending on the type of building you are trying to construct. Most of the time, Nickel Alloy will be better at withstanding corrosion, environmental damage, and water sustainability.

ROHS is to restrict certain dangerous substances commonly used in electronic and electronic equipment. Any time you see Rohs it is being checked for the presence of Lead (Pb), Cadmium (Cd), Mercury (Hg), Hexavalent chromium (Hex-Cr), Polybrominated biphenyls (PBB), and Polybrominated diphenyl ethers (PBDE). For Cadmium and Hexavalent Chromium, there must be less than 0.01% of the substance by weight at raw homogeneous materials level. For Lead, PBB, and PBDE, there must be no more than 0.1% of the material, when calculated by weight at homogeneous raw materials. Any RoHS compliant component must have 100 ppm, or less of mercury and the mercury must not have been intentionally added to the component. In the EU, some military and medical equipment are exempt from RoHS compliance. (According to,2014)
