Steel grandstands
The old site shows the seat and leaves the structure to someone else. Here the beam, the riser and the seat are one clause.
The telescopic photograph is from the BoxTech archive. The structural calculation is signed by the project engineer. The seat is signed by the factory.
Types in this section
Each type is a full page: what it is, where it sits in the hall or the bowl, and what the bill of quantities must say before a price is asked.
- 01Fixed grandstandFor a stadium or a university. Steel sized for live load, with the aisle and the accessible route in the drawing, not in the margin.Beam, riser, aisle and seat. Live load is signed by a structural engineer.
- 02Telescopic grandstandOpen for a concert, closed for the floor. Onik and Chronos mount on it because the upright width is already calculated.Open for the event, closed for the floor. Upright seat depth is the closing constraint.
- 03Galvanized outdoor grandstandFor the heat of Riyadh, Jeddah and Tripoli. Galvanizing and a polymer seat together, not rust under a new chair.Heat, dust and sun: galvanizing and a seat that tolerates UV, with no invented lifespan.
- 04Demountable grandstandFor an exhibition or a temporary tournament. It comes down and goes up again. The spare is a hinge, not a whole beam.Numbered parts, an exit drawn before tickets are sold, and a rebuild that is not luck.
