Head Restraints
Blockwork
Head Restraints are designed to secure the top of masonry walls while allowing controlled vertical movement caused by structural deflection, thermal expansion, and other building movements. These systems ensure stability of the wall without imposing unnecessary stress, reducing the risk of cracking at the head joint.
Material Standards
Sheet
Mild Steel to ASTM A1008 or BS 1449-1
Hot Dip Galvanized after fabrication to ASTM A153 / BS EN 1461
Pre-Galvanized Steel to ASTM A653 / BS EN 10346 (replaces BS EN 10327)
Stainless Steel to ASTM A240 / ASTM A666 / BS EN 10088
a. Adjustable Head Restraint
Adjustable Head Restraints are used to provide secure lateral restraint at the top of masonry walls while accommodating vertical movement. This allows the structure to absorb deflections and thermal expansion without transferring excessive stress to the masonry.
Key Features
Restrains top of masonry walls securely
Allows vertical movement due to structural deflection
Accommodates thermal expansion and contraction
Reduces risk of cracking at wall head joints
Adjustable design for flexible installation
