🛠 Profile tube 80×80×4,0 mm — thick-walled square for powerful columns
Profile tube 80×80 mm with wall thickness 4,0 mm is the strongest version of the 80×80 square section. Electric-resistance-welded steel tube made from grade Ст3 (С235), weighing 9,55 kg/m due to its thick wall provides maximum load-bearing capacity for this section. It is chosen for heavy-duty support columns, racks of canopies and long-span hangars, trusses and major industrial frames.
🏗️ Main areas of application:
- Strong supporting columns: vertical load-bearing elements for heavy loads.
- Stacks of sheds and hangars: supports of a large span under snow load.
- Trusses and frames of heavy gates: load-bearing elements with significant forces.
- 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 8639-82 / 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 Cross Section: Real 80×80×4,0 mm, smooth butt welding geometry.
- Thick wall: the 4,0 mm wall provides the highest load-bearing capacity for the 80×80 section.
