VE1 Heavy Duty Safety Vertical Twist Ties

VE1 Heavy Duty Safety Vertical Twist Ties are designed for superior performance in structural masonry applications where strength, durability, and moisture control are critical. Suitable for most buildings in the UK—regardless of height—and for cavity widths between 50mm and 150mm, these Type 1 wall ties offer a secure and compliant solution. The vertical twist feature is engineered to interrupt moisture paths across the cavity and allows for installation in either orientation. Manufactured from grade 304 stainless steel, VE1 ties deliver long-term corrosion resistance, making them a dependable choice for robust and regulation-compliant wall construction.
