🛠 Profile tube 80×40×4,0 mm is a thick-walled beam for heavy spans
80×40 mm profile tube with 4,0 mm wall thickness is the strongest version of a deep beam. Electric-resistance-welded steel tube made from grade Ст3 (С235) weighs 7,03 kg/m. Its 80 mm section depth and 4,0 mm wall provide maximum bending resistance. It is chosen for long-span beams, load-bearing cross-members, trusses and support beams.
🏗️ Main areas of application:
- Heavy long-span girders: height and thick wall hold the maximum load.
- Loaded crossbars and support beams: bearing horizontal elements.
- Farms and industrial frames: rigid elements with significant forces.
- Major load-bearing structures: critical connection points under concentrated load.
✅ Advantages of the steel pipe from SteelStream
We supply profile tubes in standard 6 m lengths in accordance with ГОСТ 8645-68 / ДСТУ EN 10219. A complete table of weights, cross-section, wall thickness and tolerances is in the Structural Hollow Section Technical Guide.
- Exact weight: you pay for the actual linear length, without the lightweight wall.
- Honest Section: Real 80×40×4,0 mm, flat geometry for butt welding.
- Thick wall: the 4,0 mm wall provides the highest load-bearing capacity for the 80×40 section.
