Look no further than BM Steel for square ERW tubes that you can trust to do the job and to do it well.

To manufacture our tubes, high-quality mild steel is formed and then welded together by an electrical current that creates a powerful, seamless bond without the need for welding filler material. The result is a square ERW steel tube that’s durable, reliable, and robust.

Our square ERW tubes can bear large loads and withstand pressure, thanks to their high bending, compressive, and tensile strengths. You can confidently use them for a wide range of applications, such as structural parts, building frames and trusses, barriers and fencing, industrial machinery support structures, bridges and pedestrian walkways, and beams and support columns.

These steel square Electric Resistance Welded tubes also boast a stable structure and high dimensional accuracy that makes them ideal for applications that require stability and accuracy. They have good corrosion resistance after galvanising or other surface treatment, making them adaptable to different environments, and they’re cost effective.

Choose from a wide range of top-quality square ERW tube sizes at BM Steel and enjoy the convenience of shopping online.

What is the difference between square, rectangular and round ERW tubes?

There are a few differences between square, rectangular, and round ERW tubes, starting with the shape of their profiles. Square ERW tubes’ profile has four sides of equal length, while the length of rectangular ERW tubes’ profile is greater than the width. Round ERW tubes have a circular profile. Square and rectangular tubes join easily and offer rigidity and stability, making them a good choice for architecture, construction, and manufacturing applications. Round ERW tubes arguably are the most common ERW tube shape and are ideal for various applications in different industries.
