About
D-marc have developed a demarcation barrier solution for flat roofs.
The D-marc demarcation system is made up of 4 simple to install components;
• The base – a 16.8Kg recycled rubber non-penetrative base.
• The upright – 950mm high trapezoidal construction, manufactured from 304 stainless steel with an orange powder coated finish.
• The chain – 25m bag of orange & black polyethylene chain
• The connector link – split link used to join lengths of chain
Where ever roof access is required designers / duty holders are tasked with creating a safe route to and from the workplace. D-marc demarcation provides a collective protection solution following the doctrine “prevention is better than cure”.
D-marc 105 has been wind tunnel tested on single-ply, bituminous and concrete roof surfaces resisting wind speeds in excess of 105 mph.
