Precision Rolled & Welded Steel Rings

At Arntzen Corporation, we specialize in the fabrication of rolled and welded steel rings and ring segments, crafted from a wide range of formable grades of carbon steel, stainless steel, and nickel alloy materials. Our rings are engineered to meet strict dimensional and mechanical specifications for structural, industrial, and specialty applications.

We roll rings from flat bar, round bar, and square bar, with flat bar rings available rolled the “easy way” or “hard way”, depending on your design and structural needs. Rings can be left as open butt joints or fully welded and thermally stress relieved to ensure maximum durability and structural integrity.

With the capability to roll from 10 inches to 180 inches in diameter, thicknesses ranging from 3/16” to 3”, and in various widths, Arntzen delivers high-precision custom solutions to meet the most demanding project requirements.

We offer several advanced forming processes to suit your specific design and strength requirements:

Rolled and welded rings – Rings are fabricated by forming flat bar or plate steel into a circular shape and then welding the seam to create a solid, continuous ring. This is one of the most versatile and cost-effective methods for producing large-diameter rings used in structural, architectural, and industrial applications.

Flash Welding for Rolled Rings - Flash welding is a high-speed resistance welding process that joins the ends of a rolled steel ring by applying electrical current and pressure, creating a strong, seamless bond. It’s commonly used for carbon and stainless steel ring fabrication where consistent mechanical properties are required. 

Forging Process for Steel Rings - Forging is a precision forming process where metal is heated and shaped using compressive forces, often with a die or hammer. When applied to ring manufacturing—commonly referred to as ring rolling or closed-die forging—the goal is to produce seamless rings with refined grain structure and exceptional strength.
