Anchor Selection

The Construction Products Regulation stipulates that all anchors sold for safety critical applications should have suitable approval. These approvals are called European Technical Assessments and are awarded after the anchor has undergone rigorous testing. Approved anchors will display the approval, carry the CE mark and have the manufacturer’s “Declaration of Performance” which is a guarantee of the loads they will take.

With the majority of mechanical and electrical installations being suspended from the building’s ceilings, these are deemed as safety critical and anchors should be suitably approved.

MIDFIX has developed a comprehensive range of ETA approved anchors particularly suited to the requirements of building services contractors. The ETA badges shown against the products identify the applications they are approved for.  Our sales team can advise you on selecting the most suitable anchors for their applications.  It is important to consider every aspect of the installation to ensure the anchor is suitably approved and will safely hold the required loads.  Another important consideration is the ease of installation particularly where large numbers of anchors are being used. 

BS8539 is the code of practice for the selection and installation of anchors and was introduced in 2012 to define the responsibilities around the correct selection and use of anchors. It is followed by industry leading building services contractors.

Fixing Selection Boards

A key challenge on sites is to ensure that the right fixings and anchors are being used across the project.  Anchors used in building services installations are seldom specified and the building services contractor and sub-contractors may often be using several different products on the same installation and very often this will include unapproved anchors.

Our Fixing Selection Boards are a great way of ensuring consistency. Working with the contractor, we will identify suitable anchors for the project, often including site testing and technical submissions. We produce a site specific board with physical samples of the approved anchors together with supporting data as a highly visual on site specification. This is an effective way of creating awareness of the approved products across all parties and ensure best fixing practice for the project.

Anchor Testing

Our site sales team are CFA approved to undertake tensile load testing to the recommendations of BS 8539.  A common requirement is ‘proof testing’ a sample of anchors to verify they are installed correctly and give the required load.  Test results are documented and presented in a test report to the contractor.
