Lead Sheet 450 x 450 x 15kg

This is a high-purity lead sheet cut to 450 x 450mm at approximately 15kg, supplied as a special order size. It is the traditional material for flashing, chimney detailing, valley linings and waterproofing, and it is also used for acoustic lining and radiation shielding. The sheet is roughly Code 3 lead, which balances flexibility and formability for precise flashing work, and it conforms to AS 1804 for purity.

How To Use It

Cut the sheet to shape with a lead knife and form it around the flashing detail with lead dressing tools. Fix it with non-ferrous nails, screws or copper clinch fixings, and overlap joints by at least 100mm. Dress the edges into the sealant or mortar to compress the joints, and apply patination oil if you want to slow the oxidation of the new lead surface.

Applications

• Step and counter flashings on pitched roofs
• Chimney saddles and lead aprons

Frequently Asked Questions

What thickness is this lead sheet?

The sheet is approximately 15kg, which is equivalent to Code 3 to Code 4 lead at roughly 1.32 to 1.8mm. It balances flexibility for flashing with the durability to hold its shape.

Why is it a special order?

This is a less common sheet size, so it is cut to order rather than held as a standard stock item. Order it ahead of the job so the lead is ready when you need it.

Can I use it for chimney flashing?

Yes. Lead is the traditional material for chimney saddles, aprons and step flashings because it is soft enough to form around the stack and durable enough to last for decades.

How do I fix it?

Use non-ferrous nails, screws or copper clinch fixings so the fixings do not corrode against the lead. Overlap joints by at least 100mm and dress the edges into the sealant or mortar.
