The Monkeytoe Aluminium walkway is a full aluminium fabricated system which results in a very strong walkway. Being fabricated with 2 specialised side beams means this walkway can span up to 3m with loading of 2.5kpa/m.

The Skywalk is a lighter walkway that spans a maximum of 2.4m between supports and then has the FRP Deck clipped to support beams underneath. The Skywalk is a lighter construction, but more modular.

Timber walkways cause two issues;

1. The tannin in the timber reacts with the colour steel and will often begin corroding within one year of installation. Even where malthoid has been installed between the timber and the roofing, the same reaction happens.
2. Timber retains moisture which keeps can keep the roof wet 100% of the time. Colour steel must be given a chance to dry out and without that chance it begins to corrode. Although timber is sometimes more cost effective to install, it will cause many longer term maintenance issues and associated costs.

When the walkway is near a potential fall area of more than 300mm so generally when the roof has a pitch of more than 7°.

Monkey Toe top fixing roofing clips have specially fabricated jack stud which is threaded into the roofing clip then sits on the purlin below. The Jack stud is then tek screwed onto the purlin and the Monkey Toe clip screws down the outside of the stud until it is sealed onto the roofing profile. Using this unique Monkey Toe fixing, all loads are transferred to the building structure – not the roofing product.

Generally you will see a nail or tek screw line in a top fixed profile.

Generally when the platforms is closer to the edge of a roof than 2000mm and when raised more than 300mm above that of an adjacent platform or the Roof. (For further detail refer toAS/NZS 1657, 1992).

When closer than 2000mm from the roof edge or where the potential to fall more than 2000mm high is apparent.

The standard units are 0-80kg, HD are 80-150kg and the super HDs can support up to 400kg depending on the roof pitch and the actual physical dimensions [please ask the MKT consultants for a special design].

The following detail is required:

• How many condensers do you have to mount?
• Approx. weight of Condenser Unit
• Roof profile type (so we can provide you with the correct fixing type)
• Purlin spacings (our mounts span from purlin to purlin)
• Roof Pitch (we’ll make sure your Mount has enough adjustment so that the condenser will sit level, i.e. won’t be on the same angle as the roof).

A Mesh Platform provides the service personnel a service area, further enhancing the protection of your roof. It means the servicemen are working on the same level as the mechanical units, making it easier to service. It is also safer as they are working on a level area rather than standing on the slope of the roof.

Generally, the platform induced lateral loads can be transferred to braced walls/portal frames/shear walls through roof diaphragm actions by the roof sheeting or other forms of diaphragms such as plywood. In the case where the diaphragm is absent or inadequate, the lateral load transfer can be achieved through axial tension/compression actions of the purlin in the along direction and through out of plane bending and shear in the across direction. In this case the client’s structural engineer is required to carry out this check. Monkey Toe can assist with this if required.
