🛠 Profile tube 40×20×3,0 mm is the strongest rectangle of its section
40×20 mm profile tube with 3,0 mm wall thickness is a reinforced version of the most popular rectangle. Electric-resistance-welded steel tube made from Ст3 (С235), weighing 2,54 kg/m, thanks to its thick wall, can withstand a significant sign-changing load without deformation. It is chosen for heavy gates, support frames and load-bearing frames in construction and mechanical engineering.
🏗️ Main areas of application:
- Heavy gate with solid filling: thick wall holds mass without sagging.
- Supporting frames and jumpers: loaded nodes of structures.
- Industrial frames: elements under significant load.
- Engineering constructions: 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 40×20×3,0 mm, flat geometry for butt welding.
- Reinforced wall: 3,0 mm — maximum rigidity for cross-section 40×20.
