Bangor Blue County Slate

Bangor Blue County Slate

Technical Section

Penrhyn Bangor Blue slates come in standard sizes of 500 x 300mm (20” x 12’’). However, specialist sizes are available on request and large format are popular for conservation projects where the architect may want to replicate the original size of slate used in the previous century. In a recent example of a Cathedral in Liverpool, we supplied slates which were size 1200cm x 600cm to match the original sized slates supplied in the 1700s.
