Bolted connections in multi-storey steel frames and structures have been the Achilles' heel in fire resistant design - they are crucial, particularly with the advent of disproportionate collapse design criteria as defined by EC3 and BS 5950. Intumescent paint protected bolted connections can be under-protected in fire.

There are globally a number of fire threat curves, which vary in fire load intensity. Bolt caps are the only product to have been tested extensively against all these various fire threats and show consistent performance in them all. 

The bolt cap with a mechanical tap on fixing is available as the standard product, also available are bolt caps with a screw-fix system (SF).  A further AC bolt cap variant is also going to be introduced shortly, which will incorporate anti-corrosive properties as well as the fire protection.

The bolt cap has also undergone VOC testing to the California building code and a more demanding semi-conductor standard and has negligible VOC.

The bolt cap provides a quick fit engineered solution to the provision of consistent quality fire protection, it is outside the scope of REACH regulations, does not have a shelf life and the bolts do not need special preparation before application and can be applied in any weather providing fire protection for cellulosic, hydrocarbon, jet fire and high heat flux jet fire scenarios very efficiently with easy inspection and verification.

Bolt Caps Are Easy To Use Giving Cost And Time Savings In Any Weather

  • Cost Savings - quick and easy to apply - up to 9 times faster
  • All weather application
  • Quick & easy inspection of joints
  • Consistent quality to all connections
  • Quick & easy cyclic inspection if required
  • Tap on and screw on fitting available
  • Tailored masking inserts available for extra speed of build
  • Health & Safety benefits - less working time at height
  • Standard metric, imperial and custom sizes and shapes available
  • Negligible VOC

They provide engineered protection and are simply snapped into place as shown, need no surface primer or preparation, make inspection easy and are ideal for speeding up the build rate or recover programme time.

New application such as corrosion & erosion protection and protecting concrete anchors are also taking place (see the news section).

Cellulosic and hydrocarbon tapon bolt caps are available direct or via distribution globally.

Interchar and Chartek bolt caps are also supplied in conjunction with and on behalf of Akzo Nobel
