For Fire Safety…

Nothing protects better than sheet steel.

Because sheet steel is inherently non-combustible, it offers maximum protection from fire, not surprisingly, it adheres to even the most strict safety regulations.

The design of buildings often requires that an assembly have a minimum fire resistance rating. ULC W605 is a listing for an insulated sheet steel wall assembly with a 1 hr fire resistance rating and W606 is for a 2 hr assembly. The listings are available from the ULC online directory. To access this directory, go to and then follow the links to the Online Directories and search for W605 or W605 as appropriate. It is recommended that you check the ULC directory for the most current version of any listing.
