The Otara System

Tiered Light Weight Demountable Modular Grandstand Seating System Specifications

The grandstand structure is based on the innovative design of modular shipping containers and has been developed to produce a retractable folding stadia seating system. By its modular design, it is stronger, faster to assemble and more versatile than other event seating.

Any size grandstand can be designed within the container modulation design concept – as building blocks (limited to truck transport modules).

The rear four rows compact and fold down onto the first three seating rows for movement and storage purposes. Each module provides 85 to 126 seats purpose designed and is a self-contained seating unit.

Seat and balustrade units are independently fixed to the terrace decks to provide a safe interlocking seating area.

The system is available in a number of different platform depths, riser heights and seating space configurations.

The system is designed with a live load capacity of 5KN/m² and a dead load of 0.25KN/m².

The system is hot dipped galvanised for an extended life protection.
