55kg Code 4 Roll of Milled Lead Flashing 450mm x 6m

55kg Code 4 Roll of Milled Lead Flashing in a 450mm width and standard 6m length, delivering approximately 2.7m² 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 450mm wide, this is suited to chimney flashings, valley linings, dormer flashings, and general abutment work in pitched or flat roofs. 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.
