Building designers are required by law to take account of post-construction safety during the design stage. RigiSystems' systems approach to roofing construction can aid considerably in the designing in of passive safety, for instance in the detailing of wall/roof parapet interfaces and the provision of wide, walkable and durable gutter systems.

Passive safety is not always possible, however, and RigiSystems supplies a range of fall arrest or fall restraint systems all of which have been thoroughly tested in conjunction with the Ziplok standing seam and with trapezoidal systems. Exhaustive testing is carried out with the load in various directions, and the applied loads are measured and recorded by the transducers wired back to the recording system. The secure attachment of the system to the roof is therefore assured, whatever the gauge of metal or profile you are specifying, as well as the performance of the fall restraint system itself.

RigiSystems' fall arrest systems use either an 8 mm 316 stainless steel cable, a unique 16mm polyester parallel fibre cable, or an extruded aluminium rail. All systems offer exceptional benefits and the polyester parallel fibre cable is available in a range of colours to suit a building’s exterior.

Systems can be fitted not only to any of RigiSystems's roofing products, but also to other manufacturer’s systems, including membrane roofs.

Safewire stainless steel cable system

Based on a high quality steel cable, the Safewire system allows multiple workers to attach at any point on the cable and move over the intermediate support brackets using the special attachment device.

The Safewire system offers a cost effective fall arrest system where cost is a major consideration, with spans between support anchors of up to 12m, minimising cost and reducing the effect of clutter on the roof.

Safecord synthetic cable system

Constructed from a unique 16 mm polyester parallel fibre cable, with a minimum breaking strength of 76 kN, the Safecord system also allows workers to attach at any point on the cable and move over the intermediate support brackets using a special locking link device, allowing complete freedom of movement and security. Special corner units allow passage around a variety of corner situations, and intermediate supports at 16 to 30m centres help preserve the integrity of the roofing fabric.

The Safecord system is unrivalled in the market place for its unique construction, unique fall arrest capability and overall competitive advantage. It has a built-in wear indicator, offers low deflection, reduces structural loading and is capable of supporting multiple workers for fall arrest. In addition it has a high resistance to many chemicals and environmental conditions.

Force management anchors

RigiSystems have developed a range of roof anchors which support the cable systems when used on a variety of roof structures, including Ziplok and Lokroll.

These special patented anchors permit the use of roof sheets as structural anchors, by limiting the forces to less than 10 kN through a built-in energy absorber. They are fitted with minimal disruption, are self-sealing and preserve the integrity of the roof structure, by eliminating the need for through-fix posts in many cases. All anchors are certified to BS EN795 Class A and C. Early consultation is recommended to ensure the correct technical and design detail is achieved.

Saferail

The Saferail system is the very latest in fall protection technological development. The extruded aluminium rail system can be retro-fitted if required and provides an extremely aesthetically pleasing system, being almost flush to the roof surface.

Saferail eliminates many potential hazards associated with cable based systems such as cable fretting, cable tension, cable deflections and swing fall hazards, so providing an extremely safe and functional safety solution. In addition, even load distribution through the fixing system ensures complete safety in the event of a multi-user fall without damaging the integrity of the roofing system.
