Q. What’s the approx. weight per metre of MonkeyToe Aluminium Walkway?
A. The Walkway decks weigh 8kg per metre. The weight of Walkway Supports varies depending on the length used. (Allow 2.15kg per metre) A 1300mm Walkway support weights 2.80kg (e.g. which suits 1200mm purlin spacings). A 2500mm Walkway support weights 5.38kg (e.g. which suits 2400mm purlin spacings)


Q. What’s the main difference between the Aluminium Walkway and the Skywalk Walkway?
A. 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.


Q. Why don’t timber walkways do the job?

A. 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.

Q.  What’s special about your roof fixing method, how does it work?

A. 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.

Q. When does a walkway require handrails?
A. 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°.


Q. On a raised plant platform when are safety handrails required?
A. Generally when the platforms is closer to the edge of a roof than 2000mm and when raisedmore than 300mm above that of an adjacent platform or the Roof. (For further detail refer toAS/NZS 1657, 1992).


Q. At what point near the roof edge are handrails required.
A. When closer than 2000mm from the roof edge or where the potential to fall more than 2000mmhigh is apparent.


Q. What is the maximum weight that your condensers mounting system can support?
A. 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].


Q. How do we know whether the roof profile is top fixed or hidden fixed profile?
A. Generally you will see a nail or tek screw line in a top fixed profile.


Q. What do we need to know to order a Condenser Mounting Frame?
A. 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).


Q. What are the advantages of having a Mesh Platform over a Skeletal Platform?
A. 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.


Q. How do we know whether the roof profile is top fixed or hidden fixed profile?
A. Generally you will see a nail or tek screw line in a top fixed profile.


Q. Does MonkeyToe cover the Engineering of Plant Platforms?
A. Yes. All platforms have either generic design or are designed as job/project specific.


Q. At what height does a modular ladder required a safety cage?
A. This does depend on how the permit for the building was done as the department of building and housing and the AS/NZS 1657, 1992 have different interpretations but we recommend any ladder that is 3m-4m from the ground to the top rung to have a safety cage.
