Reproduction Slate

manufactured in the ukManufactured in the UK

As with our stone products each individual slate is hand crafted using moulds taken from natural slate originals. The fine edge detail and textured surface combines with realistic colouration to create an attractive alternative to natural slate.


The tensile strength that results from glass reinforced cement construction allows the slates to be cut easily, without cracking or breaking and offers a 33% saving in weight compared with the natural equivalent.

Our roofing slates have been designed in consultation with professional roofers and architects, to achieve an easy to lay and uniform slating format.

Weight 30kgm2

The light weight construction of our slates saves on labour and timber costs, approximately 33% with our slate products.


Our slates are constructed from Glassfibre Reinforced Concrete (GRC). Construction allows easy cutting without cracking or breaking. Our slates weather like natural slate not concrete, unlike aggregate based concrete products that can show aggregate through their surface due to weathering over time.

In a recent document The International Glassfibre Reinforced Concrete Association recommend that for good quality GRC, ductile lifetimes of at least 60-80 years can be confidently expected in UK weather conditions (Source: www.grca.org.uk).
