Lattice Joist Systems

Lattice joists provide an efficient and versatile solution for floor and roof structures, combining strength with reduced material weight and enhanced service integration. At Build With Steel, our lattice joist systems are engineered to deliver structural performance while supporting faster, more coordinated construction.

Key Benefits

Efficient Structural Design

Lattice joists are formed using a triangulated web between top and bottom chords, creating a lightweight, but highly efficient structural element. This configuration allows loads to be distributed effectively while minimising the amount of steel required, resulting in a strong yet economical solution.

The open web design also enables longer spans compared to traditional solid sections, reducing the need for intermediate supports and allowing for more flexible layouts within the building.

Integrated Service Zones

One of the key advantages of lattice joists is the space created within the web structure. This allows building services such as electrical, plumbing and HVAC systems to pass through the joists without the need for additional drilling or modification.

By incorporating service routes into the structural design from the outset, coordination between trades is significantly improved, reducing clashes on site and simplifying installation.

Precision and Off-Site Manufacturing

All lattice joists are manufactured off-site to exact specifications, ensuring consistent quality and dimensional accuracy. This level of precision enables rapid installation on site, with components fitting together as intended and minimal need for adjustment.

Off-site production also reduces waste and improves overall efficiency, supporting a more controlled and predictable construction process.

Reduced Weight, Improved Handling

Compared to traditional solid beam systems, lattice joists offer a lower overall weight while maintaining structural integrity. This makes them easier to transport, handle and install, improving site safety and reducing the need for heavy lifting equipment in certain applications.

Performance and Adaptability

Lattice joists can be designed to meet a range of structural and performance requirements, including load capacity, span length and integration with different floor or roof systems. Their adaptability makes them suitable for residential, commercial and mixed-use developments where both performance and efficiency are key.
