3.35 x 50mm Stainless Steel Annular Ring Shank Nails

Specific Cullen products have been specified to be fixed with 3.35 x 50mm Stainless Steel Annular Ring Shank Nails for certain applications.

On the basis of wall ties having different failures in different materials e.g, tension – nail withdrawal (timber), compression – buckling (steel), we are now no longer publishing the lowest values and to assist the Building Designer we have shown the test results, failures modes and calculations.

Guidance

Spacing also required at each side of vertical expansion joints

Closer vertical spacing may be required in exposed locations as determined by the Building Designer

Wall ties to be installed perpendicular to timber and blockwork these cannot be installed at a skew

Additional ties are required at door and window openings (spacing should be no more than 300mm vertical centres and within 225mm of the jambs at openings).

Top row of ties should be 3 courses below top of brickwork.
