Applied anti-slip treatment | Non-slip load bearing extruded aluminium bars.Guidance for specification option: 25 mm deep non-slip load bearing extruded aluminium bars joined using the unique swage lock method of construction. The bars in a nominal 30 x 100 mm mesh pattern spanning transversely across the width of the walkway are set into 65 mm deep side ‘Z’ section members. |
Toe plates | Extruded aluminium toe boards.Guidance for specification option: 150 mm high. |
Handrail system | Not required.Required.Guidance for specification option: The handrail systems consist of a 38 mm diameter extruded aluminium circular hollow section top rail positioned at 1100 mm from the walkway grillage surface and a 32 mm diameter extruded aluminium circular hollow section mid rail positioned at 0.6 m above the walkway grillage surface. The handrails are supported by 50 mm extruded aluminium circular hollow section posts fixed to extruded aluminium side palm bases which are in turn fixed to the side section members. The handrail posts are positioned at centres to match the cover length of the walkway grillage (maximum 2.133 m to suit Kalzip 305). The walkway can be installed with handrails to both sides, handrail one side or without handrails. It can be installed without handrails alongside the Kalzip fall arrest system where fall arrest capability is needed. |
