Why choose code 5 1600mm 3m roofing lead?

The code 5 1600mm 3m roofing lead roll is one of the widest and heaviest standard lead sheet formats available, engineered for major weathering applications and full-surface coverings. At 1600mm wide and 3m long, it delivers exceptional coverage for large bay roofs, parapet tops, walkways, wide gutters, heritage coverings and architectural details requiring maximum durability and lifespan.

Produced to BS EN 12588, this ultra-wide sheet offers consistent mechanical performance and uniform thickness of approximately 2.24mm. Installers choose code 5 1600mm 3m roofing lead when structural reliability, long-term stability and superior corrosion resistance are essential—particularly in exposed locations or prestigious conservation projects.

The 3m length balances coverage with practicality, keeping each roll manageable while still allowing correct bay sizing in accordance with LSTA/LSA guidance.

Typical uses for code 5 1600mm 3m roofing lead

Thanks to its exceptional width, this heavy-gauge sheet is widely used for:

• Large bay roofs with significant surface area.

Wide-sheet design considerations

When using code 5 1600mm 3m roofing lead, correct bay design is essential. Ultra-wide coverings must be divided into manageable bays incorporating drips, welts and movement joints in line with professional leadwork guidance.

• Always divide the 1600mm sheet into properly sized bays.
• Incorporate drips on longer or low-pitch areas.
• Install over a suitable
  Lead Underlay.
• Ensure appropriate falls to avoid water ponding.
• Use access boards where occasional foot traffic is anticipated.

Installation guidance

This is a heavy, structurally significant sheet and must be installed to the correct workmanship standards set out in BS EN 12588 and LSTA/LSA technical manuals. Handling should be done by two installers due to weight and width.

After laying code 5 1600mm 3m roofing lead, apply patination oil immediately to promote even weathering and minimise early carbonate staining. Ensure all fixings and clips allow for thermal expansion and contraction.

For sealing chases, joints and perimeters, use mortar or
Lead Mate Sealant.

Installation essentials

1. Prepare the deck: Fully support all areas and use correct underlay.
2. Set out bays: Divide coverings following LSTA/LSA bay tables.
3. Fix appropriately: Use copper or stainless steel fixings from our
   Leadwork Fixings.
4. Seal joints: Use mortar or Lead Mate Sealant.
5. Finish properly: Apply patination oil across all exposed surfaces.
