Sports & recreation · Large spans
A steel frame and roof over a full court — quicker to erect and easier to permit than a building, and open at the sides where the climate allows it. Sized around the court, the lighting and the way the venue is booked.
01 What the hall has to solve
A covered court fails in four ways: a column appears inside the run-off, the hall becomes an oven by midday, rain on the roof drowns out the whistle, or the lighting is hung wherever a purlin happened to be. All four are decided at drawing stage, and three of them cost nothing to fix there.
The span is set by the court plus its run-off and the side lines the referee needs. Trusses, arches or a cable-stayed frame carry the roof across that width so nothing lands inside the playing envelope or the safety margin.
A dark roof over a court turns into a radiator. A light-coloured membrane, a ventilated ridge or a translucent strip along the ridge changes the temperature under it more than any fan. Decide which before the roof build-up is fixed.
A metal sheet roof amplifies rain; a membrane is quieter, and an insulated panel quieter still. If the hall is used for coaching or events with a microphone, the roof and the side infill are an acoustic decision as much as a weather one.
Lamp positions are agreed before the purlin layout is frozen, so fittings hang from the frame rather than from improvised brackets. Side netting or mesh infill keeps balls in without closing the hall off visually.
02 Configuration
Most projects start with a single court under a portal or arch frame and add bays as bookings grow. The frame is detailed with a bolted extension point from the first drawing, so phase two does not mean cutting into phase one.
03 Photographs
Reference installations across this range. Sizes, colours and membranes vary by project — send a photo of your site and we will say which of these is closest.
04 How it works
Every project follows the same four steps. Nothing is cut until the drawing is approved and the deposit is received.
Court size, run-off, booking pattern, the side that weather comes from, and the site photos.
Frame family, clear span, roof build-up, lighting positions and the foundation loads for each column.
Priced against the drawing, with the roof, side infill, packing and delivery terms stated separately.
Frame trial-assembled, roof welded or cut, cartons marked against the erection sequence.

Usually, because there is no envelope and no permanent heating or cooling to install. The honest comparison is not the roof against the building — it is the roof plus whatever side infill, lighting and drainage your use actually needs.
Yes, and in a mild climate that is often the best value. The frame is then designed for the open condition, which is a different wind case from a closed hall — both cases should appear in the drawing package.
With a ridge or valley that collects to one or both ends, and downpipes outside the playing area. The fall and the outlet positions are fixed on the layout drawing, and the discharge point has to work with your site drainage.
The frame can be detailed for it from the start, which is much cheaper than retrofitting. Netting, mesh infill and partial walls all change the wind load, so they belong in the first drawing even if they are installed later.
