PORTAL FRAME SYSTEM
Discreet portal framing is the key to designing bespoke wide span or super-sized glazed roof structures. Portal frame legs locate into purpose-designed base plates. The sleeved aluminium profiles are bolted together in ‘Meccano-fashion’ and include purlins and welded angled trusses, as required, to provide a support structure for the roof glazing above.
Aluminium components are polyester powder coated to any RAL colour, according to specification.
Fully engineered drawings and structural calculations are all provided by the SkySpace team as part of a complete portal frame design and manufacturing solution.
Project Design and Manufacture
CAD drawings are prepared for each SkySpace project, together with itemised quotations. Complex designs can actually baffle computer software, so test-fitting of roofing elements onto the portal frame sub-structure is carried out in the factory as an essential discipline.
SkySpace portal frames are exported throughout the world, so factory pre-assembly to check manufacturing precision is carried out prior to despatch to minimise on-site issues.
Compared to welded steel alternatives, SkySpace aluminium portal frame profiles are more aesthetically pleasing and provide cleaner and more precise joints.
PORTAL FRAME PROFILES
SkySpace Aluminium portal system is lighter than steel so easier to move around on site and installing. Installation can be completed using scaffolding and a genie lift instead of a crane.
- SkySpace extruded aluminium portal frame profiles are available in multiple sizes for optimise use.
- Portal leg and base plate assemblies are typically attached at foundation level. Four rawlbolts or chemical fixings are used to anchor each base plate.
- The portal legs present a sleek appearance when fitted, neatly aligned with window-walling frames and brickwork. Eaves beam details are designed to complement standard Global roofing componentry.
- Depending on the construction, mid-span and ridge purlins are suitably deployed to brace the overall structure.
