Steel grandstands

Fixed grandstand

Beam, riser, aisle and seat. Live load is signed by a structural engineer.

Fixed means a lifespan, not a match

A fixed stand stays season after season. The seat is sometimes replaced. The frame remains. Draw the fixing so a hinge can be changed without cutting the beam. Kairos, Chronos or Amik is chosen by sector: general admission, density, or another catalogue model. Families are not mixed in one row to save a colour.

The aisle, the guardrail and the accessible seat are part of the drawing, not a safety footnote added at permit time. Aisle width is measured after the arm, not before. Any load or rake is signed by the structural engineer under the local code. This page does not issue a calculation.

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 We do not publish a steel thickness.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: One seat family per sector, and the model number in the bill.

This clause goes into the bill of quantities, with the signatory and the date of the test after installation: Aisle width after the arm.

This clause goes into the bill of quantities, with the signatory and the date of the test after installation: A structural calculation separate from the product page.

Mistakes that repeat

Copying a seat count from another ground because the photograph looks similar.

Questions about this type

Is BoxTech O2mea a structural practice?

No. We coordinate the seat and the route with whoever calculates the frame. We do not sign loads and we do not offer a steel thickness. If structural design is required, it is a separate appointment with a qualified engineer.

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.
