Code 6 Lead — Flashing Series Guide
Code 6 lead is rolled to BS EN 12588 for consistent thickness and performance. At roughly 2.65 mm thick and ~30.05 kg/m², it’s a robust choice for flashings, gutters/linings and exposed roof details where durability matters. Always install to BS 6915 and LSTA guidance.
What is Code 6 Lead?
Rolled sheet to BS EN 12588 delivers uniform thickness and tight tolerances. Purity is typically ≥99.9% with trace elements controlled for stability and corrosion resistance — ideal for long-life weatherings and heritage details.
Specs at a Glance
- Thickness: ≈ 2.65 mm
- Weight: ≈ 30.05 kg/m²
- Manufacture: milled/rolled for consistency and ± tolerance control (BS EN 12588)
Maximum Lengths & Movement
For durability and crack-free performance, limit lengths between drips or mechanical joints to around 2.25 m (2250 mm). The same rule of thumb applies to lap spacing on pitched applications. Provide drips/steps typically in the 50–60 mm range (adjust by code, pitch and exposure) and follow BS 6915 / LSTA tables for exact settings.
Where Code 6 Excels
- Roof flashings & abutments: junctions, step flashings, valley/hip details.
- Gutters & linings: parapet, box and abutment gutters sized with correct falls and bay breaks.
- Dormers & chimneys: aprons, back gutters, soakers and cheeks.
- Decorative/heritage elements: moulded weatherings, rolls and fins where longevity is critical.
Advantages
- Corrosion resistance for long service life.
- Durability under UK weather and thermal cycles.
- Malleability for complex bossing and detailing.
Standards & Compliance
Specify Code 6 as BS EN 12588 rolled sheet and install fully to BS 6915 with LSTA guidance for bays, joints, fixings, underlays and falls. See our Leadwork Standards hub for the full references.

What’s the maximum length between joints?
Plan for about 2.25 m between drips/mechanical joints, with movement control and falls set per standards.
Do I need patination oil?
Yes — apply to exposed faces to minimise staining and support even weathering.
Is Code 6 suitable for heritage work?
Often, yes. For domes/spires or very wide bays you may step up to heavier codes. Always confirm bay sizes against standards.
