Veneer Ties

A wide variety of veneer ties are available from various manufacturers. The purpose of the veneer tie, regardless of design or type, is to transfer loads from the veneer to the backup structure. Veneer ties are designed to resist compressive and tensile loads that arise from lateral loads such as from wind or seismic excitation. Some tie systems are adjustable, to accommodate construction tolerances or permit the veneer to expand and contract independently of the backup structure.

Code Requirements

The Masonry Standards Joint Committee (MSJC) defines code requirements for masonry structures.

Installation & Anchorage

Embed wall tie ends at least ½" in the outer face shell of hollow units. Embed wall ties at least 1 ½" into the mortar bed of solid masonry units or solid-grouted hollow units. Maximum spacing between ties (according to the Building Code Requirements and Specification for Masonry Structures reported by the MSJC) is 36" horizontally and 24" vertically.

Corrosion Protection

Building Code Requirements and Specification for Masonry Structures Section 2.4 F lists required corrosion protection for steel joint reinforcement, ties, and anchors. Unless otherwise required, protect carbon steel ties from corrosion by galvanizing or epoxy coating. Specific minimums are outlined in the above referenced section.
