Surface Anchors

Warning!

Before selecting any surface mounted anchor as a safety device, read this.

Design

The Safetor Surface Mounted Anchors are manufactured from Stainless Steel which are riveted and bonded to roofing profiles.

Surface Mounted Anchors:

All types of surface mounted anchors are attached directly to the roofing by either rivets or some form of screws. Because of this method of attachment, the life of the roofing that the anchor is attached to is reduced to only a few years.

Riveting any height safety anchor points to a roofing material as a fall-arrest safety device is not really recommended. There are far too many variables to make this practice a safe option.

Corrosion Of Metal Roofing:

Metal roof and wall cladding is widely used in New Zealand and Australia for all types of buildings, whereas the rest of the world tends to restrict the use of metal cladding to farm, industrial and commercial buildings. In New Zealand, 70-80% of housing is clad with metal roofs of long run or metal tiles that are made, supplied, and often installed by members of NZMRM. This is one of the reasons why the NZMRM executive agreed to invest a significant amount of money, time (4-6 years), and effort to investigate the specific causes for the deterioration that can occur when metal claddings are used in corrosive areas (predominantly by the sea) and determine how this can be avoided.

Stress:

Stress that is caused by this type of anchor plays a large role in reducing the life of the roofing iron. Roofing iron expands in the heat of the day and contracts as the day cools down. All Corrugate and Trapezoidal roofing is designed to curve or sag downward between the purlins that the roofing is fixed to. When a surface mounted anchor is attached to the roofing, it restricts the natural curve of the roofing iron between the purlins and places a greater stress factor on the anchor fixings. Within a short amount of time the roofing iron can crack at the fixings, which makes the surface anchor unsafe and the sheet of roofing iron that the surface anchor is attached to needing to be replaced.

Installation:

The installation should only to be carried out by a competent person as set out in the AS/NZS 1891.4:2009 Standards. We provide a warranty on product performance of the anchor but not the structure or the roof sheeting. It is the responsibility of the installer, building designer or building owner to ensure that the structure to which the anchor is attached will support a load as set out in Appendix F of the AS/NZS 1891.4:2009 Standard. If there is any doubt about the structures adequacy, a structural engineer should be consulted.

Warning:

Only competent users who have received training should use this equipment. (Refer to the AS/NZS 1891.4:2009 recommendations concerning selection, use and maintenance.)
