Square Bar

Stainless steel square bar is a strong, versatile solid section used in fabrication, engineering, and
architectural projects where clean edges and dependable load-bearing performance are
essential. This range is supplied as cold drawn and polished bar in standard 4 metre lengths,
giving a smoother surface finish and improved dimensional accuracy compared with hot rolled
alternatives. The polished finish also makes square bar a great option for visible components
where presentation matters.

Available in Grade 304 and Grade 316 stainless steel, square bar can be specified to suit both
everyday environments and harsher corrosion conditions. Grade 304 is the most commonly used
stainless for general fabrication, offering excellent resistance to oxidation and staining for
indoor and many outdoor applications. Grade 316 provides enhanced resistance to chlorides and
aggressive environments thanks to its molybdenum content, making it a preferred choice for
marine and coastal projects, chemical exposure, and wash-down areas.

Square bar is often selected for machined parts, frames, brackets, shafts, and custom
components where flat faces are beneficial for clamping, alignment, and accurate welding. It is
also widely used for architectural detailing, balustrade components, support brackets, and
decorative metalwork. The cold drawn process improves straightness and strength, helping with
machining outcomes and reducing rework.

Sizes listed range from 6mm up to 50mm depending on grade, with the table showing
availability by grade. If you need a stainless steel solid bar that combines a professional finish
with reliable performance and fabrication-friendly geometry, cold drawn and polished square
bar is a proven choice.
