This is Dur-o-wal
the masonry wall reinforcement with the butt-welded construction
Together with the patented trussed design, Dur-o-wal is distinguished from other metal-rod reinforcement by the electrically butt-welded contact between cross rods and side rods. All rods are held securely straight and level in a single plane, for bonding and structural efficiency.
This makes for reinforcement that exceeds accepted standards. Dur-o-wal increases the flexural strength of a masonry wall 71 to 261 per cent, depending on weight Dur-o-wal used, type of mortar, number of courses.
An independent new research study shows that Dur-o-wal tied walls outfunction brick-header tied walls. Write to any Dur-o-wal address below for 44-page test report.
