We are MACS
In recognition of the influence codes and standards can have on the use of masonry materials, the Masonry Alliance for Codes and Standards (MACS) a coalition of masonry organizations representing national, state, and regional producer associations, material suppliers, mason contractor organizations, and organized labor promotional groups was established in 1995 to represent the interests of the masonry industry within various design and construction forums.
