Cut edge corrosion treatment project in Northamptonshire
Edges and laps stabilised, sealed and protected.

Cut edge corrosion typically begins at sheet cut edges, side/end laps and around fixings where factory coating stops. UV and weathering lift the finish, exposing steel and allowing moisture to track into laps. If ignored, it progresses to leaks, staining and premature sheet replacement.

Recent project in Northamptonshire: Business Park Entrance Roof — eaves & trims; fixings; evening shift. Outcome: crisp detailing; durable protection.

Early Indicators to Watch

  • Lifting or feathered coatings at lap edges
  • Rust staining beneath laps or down elevations
  • Pinholes and hairline gaps along side laps
  • Occasional water ingress during wind-driven rain

How We Treat Cut Edge Corrosion

Lap sealing and protective coating in Northamptonshire
Specified seal widths and topcoat returns for durability.
  1. Survey & Adhesion Check: Identify delamination, rust spots and moisture routes; test substrate soundness.
  2. Mechanical Prep & Arrest: Remove failed Plastisol/paint; treat corrosion and degrease to a sound edge.
  3. Prime: Apply compatible metal primer to stabilise edges and prepared areas.
  4. Seal Laps & Fixings: Tool sealant into side/end laps, penetrations and bolt heads to specified depth/width.
  5. Protective Topcoats: Install high-performance coatings with returns beyond the lap (typically ≥50 mm) and complete QA/clean-down.

Where steel loss is advanced, selective sheet replacement may be recommended after survey.

Often no. Targeted preparation, lap sealing and protective coatings can extend service life significantly. Replacement is only advised where corrosion has caused advanced section loss.

Service life depends on exposure and preparation quality. Installed to specification, treatments provide multi-year performance. A written guarantee can be provided with a manufacturer-backed spec.
