Work Smarter with Edcon Steel

Plan Your Lengths: Hollow bar is commonly supplied in 6 m lengths. Ordering cut-to-size helps reduce waste, lowers freight costs, and means you only pay for what you need.

Choose the Right Wall Thickness: Thicker walls suit load-bearing, welded, or high-wear applications, while thinner walls are easier to machine and handle for lighter-duty projects.

Protect Against Corrosion: For outdoor or damp environments, consider stainless steel or apply suitable coatings to carbon steel. Sealing or draining ends helps prevent moisture build-up inside the bar.

Store and Handle with Care: Keep hollow bar supported, dry, and off the ground to avoid bending or surface rust. Always de-burr cut ends before handling or assembly.

Common Uses and Sectors: Engineering Steel Hollow Bar

Engineering steel hollow bar is used across civil, structural, and general fabrication projects where a combination of strength and reduced weight is beneficial.

In construction and infrastructure, hollow bars can serve as load-bearing posts, columns or pins that carry heavy loads with less weight than solid steel, such as support rods, foundation piles or bridge components.

The mining and drilling industry use hollow bar extensively for machining into thick-walled pipes, hydraulic cylinders and drill rods, where durability and toughness are crucial. In the transport sector, these hollow sections become drive shafts, axle components or roller tubes in trucks and rail cars, helping reduce weight without compromising strength.
