Roof beams
Pitched aluminium members with four open corner channels for the PVC. The hollow section and fixing holes receive the eave and ridge knuckles.
Clearspan frames & components.
From complete aluminium frames to additional bays and replacement parts, explore our span range, extrusion profiles and the components that bring a clearspan marquee together.
Five spans. One modular approach.
Choose a 3, 6, 9, 12 or 15 m width. Lengths extend in 3 m bays, with eave heights of 2.3 m or 3 m across our standard range.
3 m
6 m
9 m
12 m
15 m
End-gable supports are shown at 3 m centres. These are end-wall legs; the space between the main frames remains clear of internal columns. All five diagrams use the same metre scale.
Build the length around your site.
Four 3 m bays create a 12 m length; six create 18 m. For example, a 9 × 18 m marquee gives a 162 m² footprint. We can discuss a complete structure, additional bays or individual replacement components.
Explore structure dimensionsA closer look at the profile.
The frame range includes 94 × 48 mm and the larger 114 × 80 mm aluminium sections. The profile is specified to suit the frame, span and connection arrangement.
94 × 48 mm
Four open PVC channels around a hollow core.
114 × 80 mm
A larger section with visible internal reinforcing ribs.
Both profiles are illustrated at the same scale, with the open PVC channels and internal shapes shown. Dimensions are nominal; confirm the exact section and matching fittings when ordering.
| Section | First dimension | Second dimension |
|---|---|---|
| 94 × 48 mm | 94 mm | 48 mm |
| 114 × 80 mm | 114 mm | 80 mm |
Know your frame.
Explore the members, connectors and bracing that make up the system. Each part has a role in the complete frame assembly.
Main legs
Open aluminium uprights with continuous PVC channels, elongated connection slots and round fixing holes. Slot arrangements depend on the leg and eave-height specification.
Eave purlins
Members joining neighbouring frames at eave level. The shaped section includes lower attachment channels, with a curved flat hook fixed beneath each end.
Ridge purlins
Hollow box-section members linking frames at the ridge and along the roof slopes. Bent flat end hooks locate the purlins; their number and positions follow the frame specification.
Curtain rails
Rails used to hang and slide compatible PVC sidewalls. Specify the bay length and connection details when ordering replacements.
Ground rails
Round tubular rails with flat fixing ends, running at ground level between the legs. Match the length and end connections to the wall and frame arrangement.
Gable leg inserts
A continuous perforated hollow insert with its fitted bottom cap for the intermediate gable leg. The series of fixing holes allows the specified connection position to be selected.
Eave knuckles
Angled steel connectors joining the upright leg to the pitched roof beam. The illustration shows the fixing holes, elongated slot and connection eye.
Ridge knuckles
Two angled arms joining the roof beams at the apex, with the central purlin fitting and connection eye shown separately from the aluminium beam section.
Scissor bracing
Crossed braces fitted in the specified side bays. Bracing positions are coordinated with doors and openings; portal arrangements are available where specified.
Portal beams
Horizontal members with upright angle brackets at both ends. A specified portal arrangement can keep a side opening clear where scissor bracing would otherwise cross it.
Baseplates
Slim plates with three anchoring holes, two upright cheeks and a transverse retaining pin. The leg sits between the cheeks; anchoring is selected for the frame and site.
Wire bracing
Tensioned wire assemblies used in the specified bracing positions. End fittings and tensioning components form part of the complete assembly.
Illustrations show the component details; lengths may be shortened to make the connections clear. Confirm sizes, end fittings and bracing positions for your frame before ordering.
