Granite Paving Flags

Granite Paving Flags these can be described as "Large Element Paving" and are obviously bigger than a Paving Sett. Please see elsewhere for a definition and descriHigh Street Using paving Flag ption of Granite Paving Sets on the BBS Natural Stone website. In BS1341 they would be described or granite paving flags defined as greater than 150mm wide and up to 900mm in length and again the depth or height would typically not be greater than half of the width. Again British or European Standards would suggest for Pedestrian use the thickness should be 40mm thick as a starting point and then increase depending on the Plan or area size of the Paving Flag. For vehicular use then you would start at 63mm and go thicker as the plan size gets larger.

It should be noted however, that with Granite Paving Flags you should not go too large on the plan or area size of the flag as this can have repercussions with regards to Health and Safety in relation to lifting such heavy slabs by hand. If the flag gets heavy then lifting gear should be employed in order to protect the workers involved in the laying of such flags

So a typical "granite paving flag" would be 600x300x40mm

At the smaller end Flag size would be 150x350x 40mm, using Width x Length x Height

At the larger end the Flag size could be 600x900x65mm, using Width x Length x Height

Like granite hard landscaping setts,natural stone or granite paving flags can be dressed on top. Calibrated flags usually come in the form of being sawn all six sides, yes they are still essentially a rectangle, the top surface is “dressed” in that it would not have a purely sawn side due to slip resistance requirements. It would usually be either a Flamed top or a Bush Hammered top –sometimes referred to as fine picked. The reason for this is so that when it is wet the flag is effectively not slippy. If you were to hone, saw or polish an external natural stone flag then it would be dangerous in the wet and people could fall or slip on it.
