The walkway we used for this project is specifically designed for modern roof types such as trapezoidal profile composite or built-up-on-site and standing seam roofs. It is fully compliant with EN516:2006 requirements, and it can be used on a number of differently-shaped roofs (including flat, sloping, and barrel-shaped), with steps and a traverse option allowing for virtually any roof configuration between 0 and 35 degrees.
