Fire rating is important, as it is important to understand how many minutes or hours one has time to run out of the building before the structure collapses in the case of fire. Or how many minutes the firemen have time to try to put the fire out.
This week was an important week for Peikko North America. The latest Deltabeam fire tests were done at the Underwriters Laboratories (UL) in USA with great success.
A test slab was casted already long time ago and on June 6th was the time of burning it from underneath. And it worked beyond expectations !
We had four exposed steel specimens (without fireproofing material) with fire designs for 1h, 2h, 2.5h and 3h. The first specimen designed for one hour tested over two hours and the specimen designed for two hours tested over four hours. Four hours being highest listing UL can grant, the data from test will allow Peikko to obtain listings of 1h, 2h, 3h & 4h.
Build safe, build with Deltabeams !
