Project Overview
A US-based fitness business needed to expand its indoor training area without moving to a larger facility. The client commissioned us to design and manufacture a custom steel mezzanine platform that would create a full upper floor for fitness equipment while keeping the ground level open and usable. After reviewing the site conditions, we engineered a bolted steel structure precisely matched to their dimensions, height, and loading requirements.
Client Requirements
- Platform size: 18m × 8m (144 m² of usable floor)
- Finished platform height: 2.8m
- Design live load: 300 kg/m² to support heavy gym equipment
- Two sides mounted against existing walls (wall-supported layout)
- A staircase positioned along the 8m side for safe upper-level access
- Upper level dedicated to fitness equipment and training space

Our Engineering Solution
The mezzanine was designed as a modular bolted steel structure so it could be shipped in compact bundles and assembled on site quickly, without heavy welding. Because two sides anchor directly to the building walls, we used wall-mounted beams to transfer part of the load to the existing structure, reducing the number of internal columns and keeping the ground floor clear for daily operations.
On the open sides, we positioned hot-rolled steel columns on a regular grid to safely carry the 300 kg/m² live load. The primary and secondary beams were sized to limit deflection, ensuring the floor feels solid under the dynamic, concentrated loads typical of gym equipment. A dedicated staircase was placed along the 8m side, giving users convenient and code-compliant access to the upper training level.
Key Design Features
- High load capacity: engineered for 300 kg/m², ideal for treadmills, racks, and weight machines.
- Wall-supported efficiency: two sides tied to existing walls to maximize open space below.
- Optimized access: staircase on the 8m side for smooth and safe circulation.
- Fast installation: bolted connections allow rapid, low-disruption on-site assembly.
- Long service life: powder-coated finish for corrosion resistance in indoor environments.
Results & Benefits
The completed mezzanine effectively doubled the client's usable training floor at a fraction of the cost of relocation. The 18m × 8m upper platform comfortably accommodates the fitness equipment, while the ground level remains open for reception, storage, and additional workout zones. The robust structure has been designed to withstand the continuous, heavy use of a commercial gym setting.
