Fischerwerke of Waldachtal now have an extensive range of fire approved fixing elements which meet ultimate safety standards in passive and practical fire protection.
The best fire protection is of little use if the fixing elements are not fire tested and approved. The strength and useful life of many building components depends to a large extent on the quality of the fixing elements. Anchors and plugs play a particularly important role in passive fire protection, for instance to keep escape routes clear of falling down building elements.
The properties of plugs and anchors are specified and stipulated in a number of laws, regulations and special approvals. Depending on type and use of the anchor or plug, the approvals or fire test certificates show the appropriate values for loads and the duration of fire exposure.
Polyamide frame fixings
For approved polyamide frame plugs with zinc-plated screws it is expected that, in the event of fire, the curtained facade together with its aluminium or timber subframe will collapse first before the plug or anchor will fail. Tests have shown that the expanding section of the plug remains sufficiently fire resistant (minimum 90 minutes) in the anchoring base. Fischer offers the following anchors in this segment: the longshaft fixings SXR 10 and SXS, the universal frame plug den FUR and the frame plugs S-R and S-H-R.
