Fire Resistive Designs |
Fire Resistive Designs with TrusSteel trusses have proven to be key documents in gaining the confidence and specifications of architects, engineers and end users. These TrusSteel Fire Rated Assemblies have also proven to be living documents, undergoing frequent updates as TrusSteel, along with our partner companies in these listings, continues to expand the Listings to include different materials and material configurations.
How can you obtain the very latest version of these TrusSteel UL design reports? Go directly to the UL Web site and download them. Here is how you do it:
You can print this report from your browser (File - Print), or you can highlight everything in the report (on your browser screen), copy the info (Edit - Copy) and paste it (Edit - Paste) into Microsoft Word or other programs.
Since it has proven to be simple to obtain current UL reports directly from the UL Web site, and because these reports change so often, we are no longer carrying the text of our UL reports on the TrusSteel website.
