Several building codes now require masonry walls to be secured, but to break-away in the event of a fire. To accomplish this we offer our non-wire anchors to be manufactured from Rolled Strip Zinc Alloys. The physical and mechanical properties are listed below. The Rolled Strip Zinc Alloy is available in 1/8" or 16 gage.
Firewall anchors melt at 792 degrees and cannot be welded to steel. For conditions requiring welding, we suggest welding the #130 Weld-0n Channel Slot in plain steel or hotdip to the steel, and then use a channel slot anchor manufactured from the Zinc Alloy 710 material.
The majority of our non-wire anchors can be manufactured out of the zinc alloy material.
Below are some of the anchors commonly used as Firewall Anchors.
