Bolting is a very well understood method of making a fixing in engineering and the Gantrail bolted clips are the easiest to install. They can be used with different grades of bolt and some clips can be fitted over studs welded to the steel rail support surface.
Gantrail recommend the use of grade 8.8 bolts for all normal applications as they offer the most economical solution. Some construction sites require that only grade 8.8 bolts are used. In some cases, where a larger clip cannot be used, it is possible to use 10.9 grade bolts to increase horizontal load capacity.
Gantrail have bolted clips to fit all rail sizes including some that are no longer routinely made but are still found in some older applications. The size of the clip for any rail is in proportion with the rail it is designed to fix.
Gantrail have carried out extensive testing on clips to ensure that they will perform reliably and result in a long service life. This includes load tests on every model with external third party witness of tests and fatigue tests in third party laboratories.
Size for size welded clips give a stronger installation but bolted clips are often more convenient.
