Due to the very high quality of METROSEAL raw materials the need for additional thickness is not necessary. The IEC:61111 specification only states ‘maximum’ thickness with minimum thickness being determined by suppliers ability to pass the correct tests defined in Clause 5 of specification. The above materials do so with the ‘integral’ layflat quality of the rubber compounds use not impaired in any way.

In addition to the above our thinner grades present less of a trip hazard when laid offering additional safety to operators. Standard finishes on this type is FINE RIBBED [corrugated] one side with an anti-creep impression on reverse.
