Allland - Structural Steel Pipe
Structural steel pipe is a hollow tubular section used in construction and engineering load applications. Manufactured by seamless or welded processes (ERW/SAW) with a high strength-to-light ratio and excellent torsional resistance. Due to its durability and design flexibility, it is widely used in building frames, bridges, industrial supports, and infrastructure. With proper corrosion protection, a service life of more than 30 years can be achieved.
- Outer Diameter: 21.3mm – 2000mm (Round)
- Section Sizes:20×20mm – 500×500mm (Square/Rectangular)
- Wall Thickness:1.0 – 50mm
- Length:6m / 12m / 18m (Customizable)
Urban landmark buildings: the core skeleton of super high-rise buildings, the dome grid of large stadiums, and the seismic steel structure residential frame.
Transportation network: arched main structure of sea-crossing bridge, pier columns of high-speed railway viaduct, subway tunnel support system, port crane track foundation piles.
Energy engineering: the main structure of wind power towers, boiler support frames for thermal power plants, and protective frames for transmission and transformation station equipment.
Industrial facilities: mine conveyor corridor supports, corrosion-resistant pipe galleries for chemical plants, load-bearing columns for assembly lines in automobile manufacturing plants.
People’s livelihood projects: the main rod of smart street lamps, the skeleton of modular bus shelters, the arc roof of agricultural greenhouses, and the flood control and drainage pipeline system.
Strong and reliable
Building skeleton-level load-bearing capacity, easily supporting super high-rise buildings and large venues
No deformation under extreme weather conditions (verified in projects in severe cold polar regions and high-temperature deserts)
Flexible and versatile
Provides a full range of round, square, and rectangular tubes, which can be freely combined into creative shapes such as arches and grids
Convenient on-site cutting and hole opening, perfectly suited to complex nodes
Durable
Galvanized pipes offer exceptional corrosion resistance, requiring no maintenance for 30 years in coastal facilities
Special coated pipes withstand acid fog corrosion in chemical plants
Energy-efficient
Hollow design reduces weight by 40% compared to solid steel columns, lowering foundation costs
Factory-prefabricated production reduces construction site duration by over 50%
Environmentally friendly
100% recyclable steel reduces mining pollution
Zero dust during construction protects urban air quality
Safety assurance
Flexible deformation absorbs energy during earthquakes, ensuring building stability
Fire-resistant coatings expand when exposed to fire, providing critical escape time
STRUCTURAL PIPE needs to pay attention to anti-deformation and anti-corrosion protection during transportation. It is fixed with a special bracket to ensure the stability of the pipeline during transportation. The main modes of sea freight include container transportation (suitable for short-distance and small batches), bulk carrier transportation (economical but complex handling and handling), and dedicated pipeline carriers (safe and efficient but costly). Choose the right mode of transportation according to the actual needs to ensure that the quality of the pipeline is maximized. In terms of packaging, wooden boxes, iron frames or other special packaging materials can be used to ensure the safety of the pipeline during transportation and storage.
