Key Advantages of Super Joist and SuperMAXX Joist

Super Joists and SuperMAXX Joists are engineered to provide several benefits in construction projects. Here are some of their key advantages:

  • Strength and Durability: Both Super Joists and SuperMAXX Joists are designed to offer high strength with minimal mass. This makes them ideal for supporting heavy loads without adding unnecessary weight to the structure.
  • Accessibility for Trade Installations: The large, strengthened punch-outs along the web provide excellent accessibility for the installation of mechanical, electrical, and plumbing (MEP) systems. This design feature ensures that all trades can easily work within the webbing of the joists, making the construction process more efficient.
  • Versatility: Super Joists and SuperMAXX Joists were designed as a comprehensive system with Super Studs, but stud and joist applications can be used independently. This flexibility allows them to be incorporated into various parts of a building’s structure, enhancing their utility in different construction scenarios.
  • Cost-Effective: These joists are designed to enable larger spans with less steel, providing a cost-effective alternative for construction projects. This means you can achieve the same structural integrity with less material, potentially reducing overall cost.

Dual Purpose Punchouts: Strength and Access

The punched flange profiles of Super Joists and SuperMAXX Joists significantly contribute to their span length and strength. The innovative design of the punch-outs ensures that the joists remain lightweight without sacrificing durability. This allows for longer spans, which can be crucial in creating open, unobstructed spaces within a building. The added strength from the punched flange profiles ensures that these joists can support substantial loads, making them a reliable choice for a wide range of construction projects.

One of the standout features of both Super Joists and SuperMAXX Joists is the accessibility they provide for MEP installations. The large, stiffened punch-outs along the web not only improve span length as previously discussed, but also accommodate the routing of pipes, cables, and ducts. This not only simplifies the installation process but also reduces the need for additional cutting or drilling, which can compromise the structural integrity of joists.

Key Differences of Super Joist and SuperMAXX Joist

While both Super Joists and SuperMAXX Joists offer significant performance and convenience, there are key differences between the two:

  • Flange Design: The primary difference lies in the flange design. SuperMAXX Joists feature a double return flange, which provides added strength, stability, and stiffness. In contrast, Super Joists have a single return flange.
  • Strength and Spanning Capability: Due to the double return flange, SuperMAXX Joists offer superior strength and can span larger distances compared to Super Joists.
