In some cases, fiber manufacturers employ structural engineers, however, their sales   representatives are specialists who can assist in designing mixes using steel fiber  reinforcement. They can help you decide on the fiber type, style, and amount of fiber to use  for an application, offer advice on mix proportions, supply cost information, and sometimes even  supply the conveyors needed to load the fibers into a ready-mix truck. Our company developed a proprietary software system to help develop  designs for different applications.
