Steel grandstands

Telescopic grandstand

Open for the event, closed for the floor. Upright seat depth is the closing constraint.

Stand isolation — stadium seating by BOXTECH — A photograph from the published archive of halls, grounds and seats. It is not a generated image, and it does not mean BoxTech O2mea built the project.

The close is calculated before the cloth

A telescopic stand stores rows on top of each other. A seat that is too deep when upright stops the close or loads the mechanism. Onik is named in the catalogue for this reason: a shorter upright depth. Any other seat is checked on that dimension, not on a photograph of it open. The retractable photograph in the archive is a system reference, not a measure of one job.

Operation needs a clear path, training, and maintenance of wheels and locks. The audience is not on the stand while it moves. That is a safety clause in the use manual, not in the decor specification.

Final figures come from the drawing, the current manufacturer datasheet and a test of the room. This page is a design method, not a performance certificate and not a price.

Coordination sequence

Name the type before buying the seat: fixed stays, telescopic closes, outdoor is exposed, demountable is rebuilt. Each constrains seat depth, material and fixing differently.

Aisle, guardrail and accessible seat are on the drawing, not in a permit margin. Aisle width is after the arm. Load and fixing are signed by a structural engineer for the ground that exists. We do not publish a steel thickness.

The spare is a hinge, not a whole row. Galvanizing is reviewed after site cuts. A telescopic stand does not move with people on it. A demountable stand’s capacity is not sold before the exit is accepted.

This clause goes into the bill of quantities, with the signatory and the date of the test after installation: Upright seat depth within the closing limit set by the system manufacturer.

This clause goes into the bill of quantities, with the signatory and the date of the test after installation: An operating manual and a clear zone while it moves.

Mistakes that repeat

Questions about this type

Does every multi-use hall need telescopic seating?

No. If the rows never leave during the year, fixed is simpler. Telescopic seating is for when the floor must return to empty. The decision is use, not appearance.

Catalogue seats coordinated with this type

The seats shown are catalogue families in their own photographs, chosen with this type on the drawing, not from a separate picture.
