Welded stainless steel wire masonry joint reinforcement.
Wincro has developed a range of welded masonry reinforcement to overcome structural problems as well as crack control.
Wincro WMR is a manufactured in 2.7 m standard lengths and is used to improve the structural performance of masonry walls, in accordance with BS 5628-2: 2005, by providing additional resistance to lateral loads e.g. wind. It can also be used to reduce the risk of cracking either at stress concentrations around openings or as a result of movement, in accordance with BS 5628-3: 2005.
Available in four standard widths; 60, 100, 150 and 175 mm and is suitable for walls 100–215 mm thick.
The product is manufactured from three wire sizes and, where flattened, have an equivalent wire diameter of 3, 4 and 5 mm. Longitudinal wires have a minimum characteristic yield strength of 500 N/mm².
Wincro Double Span Masonry Reinforcement for collar-jointed walls is also available. Wincro WMRDCT is used to tie the two leaves of thin masonry together, so it acts as a single unit. The product consists of flat ties welded to flattened longitudinal wires. Manufactured in stainless and galvanized steel, WMRDCT is supplied in a standard width of 175 mm to suit a wall width of 215 mm comprising of either standard bricks or 100 mm blocks.
Also available in galvanized steel (specified separately).
