In architecture, a string course (otherwise known as a band course) is a horizontal band in a building. A string course or band course can either be flush with brickwork or projecting to provide an interesting architectural feature - often used to break up a monotonous expanse of brickwork. A string course or band course is an aesthetic device that occurs in virtually every style of Western architecture from classical Roman through Anglo-Saxon and Renaissance to modern. String courses or band courses are often used in conjunction with other architectural dressings such as plinth courses and quoins. The Q350, Q370, Q371, Q400 and Q450 are our standard string course designs.
