Tie Down has always believed in growth through innovation in both product and manufacturing capabilities. In the early 80's, Tie Down became one of the first manufacturers in the Southeast to incorporate robotic welding. Early 90's brought CNC sheet laser cutting permitting the growth of products no longer dependent on the older legacy manufacturing methods that traditionally required great expense in both hard tooling and higher volume run requirements from coiled steel. CNC laser cutting also allowed much greater freedom in engineering design as the shapes and profiles being produced in CAD were no longer constrained to hard tooling. Tie Down was also an early adopter of 3D modeling as well as FEA analysis when such tools were still in their infancy.
