37kg Code 4 Roll of Milled Lead Flashing 300mm x 6m

37kg Code 4 Roll of Milled Lead Flashing in a 300mm width and standard 6m length, delivering approximately 1.8m² of coverage per roll.Code 4 refers to a nominal thickness of 1.80mm, equating to 20.41kg per m², making it the standard grade for general-purpose flashings that balance strength with workability. At 300mm wide, this is suited to chimney back gutters, aprons, and wide cover flashings across standard-sized chimneys and roof abutments. Manufactured to BS EN 12588, the milling process produces uniform thickness, fine grain structure, and a smooth finish for reliable installation. Its purpose is to provide a malleable, durable, and completely waterproof seal at critical junctions - including abutments, chimneys, and parapets - preventing water ingress and extending the lifespan of the building fabric. Application of patination oil after installation is essential to prevent carbonate staining.
