Bar Grating Now from PalmSHIELD
PalmSHIELD is excited to announce the addition of our new aluminum bar grating railing and fence panel system specifications and CAD drawings. This information will make it easy and complete for architects and engineers to provide a complete set of specifications for bar grating panel systems. PalmSHIELD has been successfully manufacturing aluminum and steel bar grating railing products for over twenty-five years.
Our new bar grating system is a complement to our current array of louvered, square mesh, and perforated metal systems. All of PalmSHIELD’s products utilize our proven picture frame system, engineered structural post design, Gorilla hinges, internal locking devices, and fully framed gates. PalmSHIELD is working in cooperation with AmeriFence Corporation of Madison. One more reason we are your Madison fence company.
