Characteristics
Materials and forming processes
Material type:
Carbon steel.
Forming process:
Cold forming process, welding or seamless method can be selected. The cold forming process increases its yield strength and tensile strength while ensuring tight dimensional tolerances for structural applications.
Performance characteristics
High strength and durability:
In particular, grade B, C and D pipes have high strength and durability and are suitable for heavy load and high stress conditions.
Weldability:
With excellent weldability, the pipe can be easily welded to other materials without losing structural integrity.
Impact resistance:
High strength and good uniformity, with good impact resistance.
Corrosion resistance:
Although it has a certain resistance to general environmental conditions, corrosion resistance can be improved by additional treatments such as galvanizing or painting.
Applications
1. Construction industry
Steel frame: Support structures used in buildings, such as columns, beams and frames, that can withstand heavy loads and high stresses.
Stairs and balustrades: as safety support structures within the building.
Bridge construction: Used for the main load-bearing components of Bridges such as beams and longitudinal beams to ensure the reliability of the structure under various environmental conditions.
2. Industrial use
Mechanical brackets and equipment frames: used to support production lines and heavy machinery to ensure the stability and safety of equipment.
Conveyor system support: Used to support conveyor belts and piping systems.
Industrial equipment: such as power equipment, mining machinery, etc.
3. Transportation
Railway structure: Used for railway track support and signal towers.
Car and truck frames: used for vehicle frames and mechanical support components.
Ship structural frame: used for support structures and chassis of ships.
4. Municipal infrastructure
Street lights and poles: used to support urban street lights and power transmission towers.
Traffic sign support: Support for road signs and traffic signal systems.
Water pipes and pipe supports: used to support urban water supply and drainage systems.
5. Agriculture and irrigation systems
Greenhouse structure: The supporting frame for the greenhouse.
Irrigation system: Used to support irrigation pipes.
6. Communications and energy
