The Stanley Roofing Square is a 400 x 600mm steel square designed for roofing calculations and stair layout work. Built from durable steel with a buffed finish and protective lacquer coating, this metric roofing square provides reliable accuracy for professional roofers and carpenters working on complex measuring tasks. The face of the square features graduations every 2mm for standard measuring work, whilst the reverse of the blade is graduated every 1/8 inch to accommodate detailed work requiring imperial measurements. This dual measurement system makes it particularly useful on sites where both metric and imperial dimensions are encountered. Crisply embossed graduations ensure the markings remain legible even in challenging light conditions, whilst the reversed reading scale allows measurements to be taken from multiple angles. The protective lacquer coating provides rust resistance, helping maintain accuracy and extend the working life of the tool when used in exposed external environments typical of roofing and construction work.
