🛠 Profile tube 30×30×3,0 mm is the strongest square of its section
30×30 mm profile tube with 3,0 mm wall thickness is a reinforced version of the 30×30 square. Electric-resistance-welded steel tube made from grade Ст3 (С235), weighing 2,54 kg/m due to its thick wall provides the maximum rigidity and resistance to deformations for this section. It is chosen for heavy gates, support racks and loaded frames, where a real load-bearing capacity is required from the profile.
🏗️ Main areas of application:
- Heavy swing gate: thick wall holds massive fill without sagging.
- Support racks of canopies: vertical elements under a significant load.
- Loaded frames and columns: load-bearing elements of light structures.
- Responsible frames: designs with sign-changing efforts.
✅ 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. 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 30×30×3,0 mm, flat geometry for butt welding.
- Reinforced wall: 3,0 mm — maximum rigidity for cross-section 30×30.
