IKO D-marc» Base and Upright

IKO D-marc» is a wind-resistant demarcation system for flat roofs. Applications consist of preventing access to hazards during roof maintenance or to provide safe access across the roof. Wherever roof access is required a safe route must be created, identified by a demarcation system.

Traditional demarcation systems on roofs can suffer from instability and wind uplift causing them to fall dangerously from the roof.

IKO D-marc» has been wind tunnel tested on felt, single-ply and concrete roof surfaces, resisting wind speeds in excess of 105mph.

The Uprights
The uprights are manufactured from a 304 stainless steel to EN 1.4301, with a powder coating enhancing life-span and providing a quality finish.

The lattice structure ensures the wind circulates around and through the system rather than pushing it over. Its three connecting pins do not protrude through the base and therefore do not come into contact with the roof structure, ensuring it cannot damage the roof. It also has an integral hook to ensure the chain cannot lift off.

The Base
The base is manufactured from recycled tyres complying with BS 4790 for flammability, BS 1006 for UV stability and BS 7188 for slip resistance. Its shape is aerodynamically designed and during extensive wind tunnel testing it was shown to be the most stable shape. The weight of the base is distributed to its perimeter, minimising the effect of wind uplift.
