What is a Stainless Steel Box?
Stainless steel box section, also referred to as stainless steel square hollow section, is a hollow metal profile with a square cross-section. The profile is measured by its outer width, outer height, and wall thickness, with all dimensions listed in metric on the product page.
Stainless steel is an alloy of iron, carbon, and chromium that offers excellent corrosion resistance, strong durability, and a clean, modern appearance. These properties make it a practical choice across a wide range of industries and applications, from construction and architectural work to food processing environments where hygiene is part of the specification.
Stainless steel box section is supplied in mill finish as standard and performs well in both indoor and outdoor settings.
Sizes, Wall Thicknesses, and Dimensions
Our stainless steel box section range comes in different sizes, from 12.7mm x 12.7mm up to 50mm x 50mm, with wall thicknesses of 1.2mm and 1.5mm depending on the size. Stock lengths are available in 2m and 3m, and custom lengths can be cut to suit your project requirements. All dimensions refer to the external width of the section and are listed in millimetres on the product page.
If the stock size or length does not match what your project calls for, contact our sales team to discuss your specific dimensions or required length.
Mill Finish and Surface Options
Our stainless steel box section is supplied in mill finish as standard. Mill finish reflects the natural surface of the stainless steel profile straight from production and can be worked or further treated to achieve a specific surface finish.
Satin and bright polished finishes are available on selected stainless steel products, so get in touch with our sales team for further details on finish availability across the range.
Common Uses of Stainless Steel Box Section
Stainless steel box section is commonly used across construction, architectural applications, and general metalwork. The profile is a popular choice for handrails, frames, supports, and decorative structures where both strength and a clean finish are part of the brief.
The material cuts cleanly, is easy to work with, and can be welded to produce fabrications suited to a wide range of industries and settings, from indoor commercial projects to outdoor structures exposed to the elements.
Properties of Stainless Steel Box Section
Stainless steel resists rust and corrosion without surface treatment. The chromium content in the alloy forms a passive layer that protects the metal and repairs itself naturally if the surface is scratched.
The profile offers a good strength-to-weight ratio, consistent wall thickness throughout each length, and a clean finish that holds up well in both indoor and outdoor conditions. The material is hygienic and easy to clean, which is why it is commonly specified in food processing and commercial settings.
