8 4 5 London Extras Technical Info Also in the London Brick range are two types that are often underrated. Commons The standard brick for all purposes by virtue of its strength, durability and uniformity. It is used extensively for industrial chimneys, foundations and other specialist work. These are available in both 65mm and 73mm formats with a minimum of 25 N/mm 2 when laid frog up. Selected Regrades As well as Commons, don t forget we also have available from time to time, a range of London Selected Regrades, manufactured under the strict quality assurance system BS EN ISO 900. These are assorted bricks from our London Brick range that have been reclassified after firing because of their non standard colour, texture or because they have minor damage. Their physical properties, size, compressive strength etc are the same as for best quality London Bricks. Selected Regrades conform to the requirements of BS EN 77-. Due to their inconsistency in colour and texture however, these products are not suitable for facings.
