🛠 Profile tube 80×80×3,0 mm — reinforced square for heavy columns and supports
Profile tube 80×80 mm with wall thickness 3,0 mm is a reinforced version of a large bearing square. Electric-resistance-welded steel tube made from grade Ст3 (С235), weighing 7,25 kg/m, due to its thick wall, can withstand significant loads and sign-changing forces without deformation. It is chosen for heavy supporting columns, racks of long-span canopies, frames of massive gates and trusses.
🏗️ Main areas of application:
- Heavy support columns: vertical load-bearing elements for heavy loads.
- Stacks of long-span canopies: supports for snow load.
- Frames of massive gates: strong section for heavy sashes.
- Farms and load-bearing frames: elements of industrial structures with variable forces.
✅ 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.
- Fair Cut: real 80×80×3,0 mm, smooth butt welding geometry.
- Reinforced wall: 3,0 mm — high rigidity for cross section 80×80.
