Wincro’s Universal Column Tie is a simple and time saving solution for tying masonry to steelwork.

It is simpler to use than traditional drilling or shot firing ties or Frame Cramps.

The benefits include:

  • 4 different fitting options.
  • Ease of installation with no fitting tools or equipment required.
  • Allows for variation in coursing, and easy to handle.
  • Excellent pull-out strength.
  • Exceeds the requirement of BS5628 for a Type 2 tie.
  • Manufactured from high quality grade 1.4301 (304) stainless steel.

Variation in notch sizes allow the Wincro WTUC Tie to be easily slotted around the flange of a column and so provide effective restraint between the inner and outer leaves of masonry cavity walls.

We can also manufacture a wide range of alternative solutions for tying masonry to steelwork. Please consult our Technical Design team for further information and guidance.

Internal Column Tie

Designed to fit between the flanges of standard sized universal columns and beams, this tie ‘locks’ into the mortar joint at 225mm vertical centres (block heights) and is available in a wide variety of standard sizes to suit all standard UC and UB sections, with pre-designed holes. Contact our Design Team for more information.


Wincro recommends large plate washers (WBPW) should be used as this increases the tensile load capacity of frame cramps.

For guidance, a Wincro WTS2E Frame Cramp will achieve a safe working load of approximately 1kN when fixed at the lowest point of the slot. For more information, please contact our Technical Design Team.

Special Internal Column Tie

Non-standard stanchions and masonry offsets can be accommodated by the use of special internal Column Ties, which can be designed to suit exacting circumstances. Please consult our Technical Design Team to discuss your exact application.

Bi-metallic Corrosion

We recommend that where internal column ties are used, the untreated mild steel structural steelwork be painted with a suitable bitumen coat where the two materials come into contact. This is avoid the potential for bi-metallic corrosion between the dissimilar metals.
