🛠 Profile tube 120×80×4,0 mm — reinforced wide beam for floor slabs and trusses
120×80 mm profile tube with 4,0 mm wall thickness is a heavy-duty wide beam for highly loaded structures with a long span. Electric-resistance-welded steel tube made from grade Ст3 (С235) weighs kg/m. Its cross-section and thick wall provide high rigidity in both directions. It is chosen for floor slabs, heavy load-bearing trusses, hangar spans and support beams.
🏗️ Main areas of application:
- Floor slabs and heavy trusses: very long span under heavy load.
- Long-span hangar spans: the section depth and width help resist lateral forces.
- Support beams and folding frames: strong elements with significant forces.
- Major industrial structures: 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.
- Fair Cut: real 120×80×4,0 mm, smooth butt welding geometry.
- Thick Wall: 4,0 mm — high load-bearing capacity for the 120×80 section.
