🛠 Profile tube 40×30×3,0 mm is the strongest rectangle of its cross-section
40×30 mm profile tube with 3,0 mm wall thickness is a reinforced version of a wide rectangle. Electric-resistance-welded steel tube made from grade Ст3 (С235), weighing 3,01 kg/m can withstand a significant load in both directions without deformation due to its thick wall. It is chosen for heavy gates, support frames and load-bearing frames in construction and mechanical engineering.
🏗️ Main areas of application:
- Heavy gates and support frames: a thick wall holds mass and sign-changing forces.
- Loaded trusses: bearing elements with a concentrated load.
- Industrial frames: structures under significant load.
- Engineering units: structural frames with variable forces.
✅ 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. Guidance on selecting the section and wall thickness, weight, and installation is available in our Technical documentation.
- Exact weight: you pay for the actual linear length, without the lightweight wall.
- Honest Section: real 40×30×3,0 mm, flat geometry for butt welding.
- Reinforced wall: 3,0 mm — maximum rigidity for cross-section 40×30.
