Lead Sheet 600 x 600 x 15kg

This is a high-purity lead sheet cut to 600 x 600mm at approximately 15kg, the standard sheet size for flashing and lining work. It is a traditional, durable material for roof flashing, valley linings, parapet cappings and waterproofing, and it is also used for radiation and acoustic shielding. The sheet is supplied as Code 3 or Code 4 thickness depending on the stock batch, which covers both flexible detailing and heavier, more perforation-resistant work.

How To Use It

Shape the sheet with lead knives and dress the edges into sealants or mortar to finish the flashing. Fix it with non-ferrous fixings such as copper, bronze or brass nails so the fixings do not corrode against the lead. Overlap joints by at least 100mm and dress them down securely, and apply patination oil on the new lead to slow surface oxidation.

Applications

• Roof-to-wall abutments, chimney and dormer flashings
• Valley gutters, parapet cappings and step flashings
• Waterproof linings behind cladding and membrane
• Radiation and acoustic shielding in medical or industrial buildings

Frequently Asked Questions

What thickness is a 15kg 600mm sheet?

A 600 x 600mm sheet at approximately 15kg corresponds to Code 3 or Code 4 lead, roughly 1.3mm or 1.8mm depending on the batch. Code 3 is more flexible, while Code 4 is heavier and more perforation-resistant.

Which code should I choose?

Code 3 suits flexible work such as soakers, chimney flashings and intricate detailing. Code 4 is heavier and better for valleys, parapets and high-wear junctions. If you are unsure, tell us the job and we can advise the right code.

Is lead sheet still used for flashing?

Yes. Lead remains a trusted flashing material because it is malleable, naturally corrosion resistant and can last over a century when installed correctly. It is also fully recyclable.

How do I join two pieces?

Overlap the joints by at least 100mm and dress them down securely so water cannot work between them. Use non-ferrous fixings so the nails do not corrode against the lead.
