🛠 Profile tube 70×70×3,0 mm is a load-bearing square of intermediate size
Profile tube 70×70 mm with wall thickness 3,0 mm is a heavy-duty square tube between 60×60 and 80×80. Electric-resistance-welded steel tube made from grade Ст3 (С235), weighing 6,31 kg/m is stronger than 60×60 but lighter and cheaper than 80×80. It is taken for columns, support racks of long-span canopies, frames of heavy gates and trusses.
🏗️ Main areas of application:
- Columns and supporting posts: load-bearing elements of canopies and long-span gazebos.
- Heavy swing gate frames: strong section for massive structures.
- Farms and load-bearing frames: elements of industrial buildings.
- High pillars and supports: structures for significant wind load.
✅ Advantages of the steel pipe from SteelStream
