House Builders


Category: General


House building was at the heart of the UK government’s recent Budget. Measures such as the extension of the Help to Buy equity loan scheme and the extra £500m for small builders should help more housing projects get off the ground.

This is encouraging news but Rapid Industrial Fasteners working with some of the world’s leading suppliers of specialist fixing solutions, are warning builders not to cut corners when it comes to choosing appropriate fixings for their construction projects.

Choosing a suitable fixing

There are many key considerations when choosing a suitable fixing for a job, these include:

  • What substrate is the fixing going into (E.g. lightweight block, solid or hollow brick or plasterboard)?
  • What load (weight) does the fixing need to hold?
  • What type of installation is required, does it need to be fixed through the fixture or does the fixing need to be installed in the wall prior to the fixture being fitted?
  • Substrate factors

Modern building materials offer several challenges regarding fixing.  With greater use of lightweight aerated concrete blocks (Aircrete blocks), hollow clay bricks and thinner board materials, such as plasterboard, many traditional fixing solutions are just no longer suitable.

  • Load factors

Rapid offers data for its complete fixing range, including safe working load information with a factor of safety built in to ensure safe installation and technical advice department offering fixings advice, to ensure the correct fixing is specified for the type of substrate and weight to be held.

  • Type of installation

The two main types of installation for domestic properties are flush fixing and through fixing.  Flush fixing is when the fixing is pushed into the wall prior to the item being applied.  An example of this would be a nylon plug, with a screw for a bathroom towel rail.

However, for door and window frames, through fixing is recommended.  Builders drill through the frame straight into the substrate, the fixing is then pushed through the frame and tightened and the fixing is then supported through the framework.  Good examples of Rapids through fixings would be an ‘SXR frame fixing’, ‘

Fixing size is also another key consideration.  Most fixings require a minimum embedment into a wall, to which you then need to add the thickness of your application.

Last but by no means least, always install fixings using the manufacturer’s guidelines and never be tempted to modify the fixing in any way, if it is not suitable for the application you are using it for.
