Cut Edge Corrosion Treatment Amersham
Cut edge corrosion starts where factory coatings end — at cut edges, end laps and around fixings. UV and weathering cause the finish to lift, exposing the steel beneath. Left untreated, this progresses to leaks, staining and costly sheet replacement.
Warning Signs
- Peeling or lifting Plastisol/paint at sheet edges or laps
- Rust staining below laps or around bolts
- Hairline gaps along side laps; damp insulation or ceiling marks
- Water ingress during wind-driven rain
Our Treatment Process
- Preparation: Remove loose/failed coatings and corrosion; degrease and abrade to sound substrate.
- Prime: Apply appropriate metal primer to stabilise edges and corrosion-treated areas.
- Seal: Bed and tool sealant into side/end laps, fixings and penetrations to specified depth/width.
- Protect: Apply durable topcoats beyond lap edges (typically ≥50mm) for long-term UV and weather resistance.
- Handover: Quality checks, clean down and simple aftercare guidance.
In severe cases (advanced section loss), local sheet replacement may be recommended following survey.
