🛠 The 80×40×5,0 mm profile tube is the strongest beam of its cross-section
Profile tube 80×40 mm with wall thickness 5,0 mm is the thickest-walled version of a deep beam. Electric-resistance-welded steel tube made from grade Ст3 (С235) weighs 8,63 kg/m. Its 80 mm section depth and 5,0 mm wall provide the greatest load-bearing capacity of the section. It is chosen for heavy-duty industrial beams, load-bearing cross-members, heavy-duty trusses and support beams.
🏗️ Main areas of application:
- Heavy industrial spans: maximum load and long spans.
- Powerful trusses and supporting beams: load-bearing elements with significant forces.
- Crane tracks and floors: structures with a safety margin.
- Major industrial frames: critical connection points for 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 80×40×5,0 mm, flat geometry for butt welding.
- Thick wall: the 5,0 mm wall provides the highest load-bearing capacity for the 80×40 section.
