Welcome to Cerra Metal Works
Crack Stitching Bars are both wide and varied and they can be utilised in new buildings and for many specialised refurbishment requirements like apartment buildings, historic buildings, bridges and many more (building materials – concrete, brick, stone, wood, air concrete and others). Made from high-quality stainless steel, these bars are expertly installed into slots that have been cut into the masonry and then secured with grout, resulting in a quick and effective solution that will stand the test of time.
