Lead Sheet 450 × 450 × 15 kg – Special Order

Our Lead Sheet 450 × 450 × 15 kg is a heavyweight, high-purity lead panel designed for specialist applications where precision, durability, and performance are essential. Supplied as a special-order size, this sheet is perfectly suited to flashing, waterproofing, acoustic lining, radiation shielding, and roofing projects requiring bespoke dimensions and weight.

Key Specification

Dimensions: 450 mm × 450 mm square
Weight: Approximately 15 kg per sheet (±5%)
Estimated thickness: Equivalent to Code 3 to Code 4 lead (≈1.32 mm–1.8 mm), based on typical weights of 17 kg/m² at 1.5 mm lead thickness
Material: High-purity lead conforming to AS 1804 and equivalent international standards

Available Thickness Codes

Lead thickness is typically classified by “Code”, which corresponds to weight and durability:

Code	Approx. Thickness	Weight per m²	Typical Uses
Code 3	~1.32 mm	~15 kg	Flexible flashings, chimney detailing
Code 4	~1.80 mm	~20 kg	Durable valley linings, parapets

Our special‑order sheet is most comparable to Code 3, offering a balance of flexibility and formability ideal for precise flashing tasks

Performance & Benefits

High pliability: Soft enough to form to chimneys, abutments, and stepped profiles without cracking
Exceptional longevity: Lead is naturally corrosion-resistant and can endure over a century when installed correctly
Multifunctional use: Ideal for roofing flashings, valley liners, waterproof membranes, and even acoustic or radiation shielding in sensitive environments
Strict compliance: Meets AS 1804, ASTM B749 and QQ‑L‑201F standards for purity and safety

Common Applications

Step and counter‑flashings on pitched roofs
Chimney saddles and lead aprons
Valley and parapet gutter linings
Waterproof barriers behind cladding or under membranes
Acoustic or X‑ray shielding panels in medical and industrial settings

Installation Advice

Select appropriate code based on site wear and need for flexibility.
Fix with non‑ferrous nails, screws, or copper clinch fixings.
Overlap joints by a minimum of 100 mm.
Form and dress edges with lead slaters’ tools to compress joints.
Optionally treat with patination oil to slow oxidation.
