One of the secrets to Square-Fit’s versatility is its ability to telescope. Smaller sizes fit smoothly and snugly into the next larger size.
This is made possible by the latest in high-speed roll-forming technology with high-frequency resistance welding. This produces smooth corner welds within very close tolerances, reducing your fabrication costs.
