Steeldeck® is suitable for a wide variety of environments, including theatres, festivals, music events, fashion shows, and even for film and TV sets. The high weight loading capacity and robust construction means you can concentrate on your performance, safe in the knowledge the stage will never let you down.

The system is equally as versatile as it is strong. Single-level, tiered, and custom shape configurations are achievable. It is even possible to use Steeldeck® to construct custom tiered seating designs. You can also add a range of accessories, including step units, wheelchair access ramps, guard rails, and valances.

High durability & weight loading capacity

The major selling point of Steeldeck® is its superb durability. Each modular platform has a 7.5kN per square metre weight loading capacity, enough to hold 2 tonnes.

Modules are available in 8ft x 4ft and 4ft 4ft standard sizes, giving you the freedom and flexibility to develop your construction the way you want. It is also possible to select custom sized platforms if necessary.

You can customise modules with cutouts, rounded segments, or even triangular platforms to achieve the perfect configuration. Each platform features Russian birch plywood with a high strength to weight ratio. There is black closed cell foam with fireproofing to Class 0 on the underside of each platform.

The steel construction comes with an iron phosphate pretreatment that inhibits corrosion. Every module is a powder coated to increase the appearance, strength, and durability of the steel.

A popular choice for festivals & music events

Being such a durable staging system, Steeldeck® is the de facto choice for large events like festivals and music concerts.

Theatres use Steeldeck® to achieve the perfect set configuration, while festivals can customise staging to improve accessibility or to include space for sound equipment.

Many other uses are possible, only limited by your imagination.
