WPB Section Beam

Mechanical Properties

Wide Flange Parallel Beams (WPBs) are renowned for their substantial cross-sectional area, providing a high moment of inertia and resistance against bending and torsion. These beams exhibit superior mechanical properties, including exceptional tensile and yield strengths, making them capable of supporting large loads over wide spans. The flanges in WPBs are designed to resist bending forces, while the web resists shear stress, making them highly efficient in both vertical and horizontal load applications.


WPBs have limited bendability, which is by design to ensure their structural integrity in supporting loads. The steel composition and the beam's geometry are optimized for rigidity and strength rather than flexibility. Modifications to enhance ductility or bendability can compromise the beam's load-bearing capacity, which is why WPBs are primarily used in applications where strong, straight support elements are needed.

Dimensional Tolerance

Wide Flange Parallel Beams are manufactured with precise dimensional tolerances to ensure that each beam meets stringent specifications. These tolerances are crucial for maintaining the structural integrity of buildings and other constructions, ensuring that each beam performs as expected under load. Dimensional tolerances cover the depth, width, thickness, and straightness of the flanges and web, facilitating the design and construction of complex structures.

Corrosion Resistant

WPBs can be treated with a variety of finishes to protect against corrosion, extending their lifespan and reducing maintenance requirements. Protective measures include hot-dip galvanizing, where a zinc coating is applied, and painting or the application of protective coatings. These treatments are essential for beams exposed to corrosive environments, such as those found in industrial, marine, or coastal applications.

Where do you need it?

Wide Flange Parallel Beams are versatile and can be used in a vast array of projects across multiple sectors, including:

  • Commercial and Residential Buildings: As primary support structures in the construction of high-rise buildings, office complexes, and residential developments.
  • Industrial Facilities: Providing the backbone for large warehouses, manufacturing plants, and other industrial buildings.
  • Public Infrastructure: Integral to the construction of bridges, hospitals, schools, and public transportation systems.
  • Specialized Constructions: Used in stadiums, arenas, and exhibition centers where long spans and heavy loads are common.
  • Energy Sector: Forming part of the structural framework for power plants, including those in the renewable energy sector.
  • Marine Engineering: For docks, piers, and other structures requiring durability against harsh marine conditions.
WPBs are a cornerstone in modern construction and engineering, offering unmatched strength, durability, and flexibility in design. Their wide flanges provide excellent resistance to bending, making them a preferred choice for projects requiring robust structural components.
