Beyond that, many people specify it on period properties simply because the profile, weight and finish match the age of the building in a way lighter modern materials don't.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes primed finish need painting on site?\u003c\/strong\u003e Yes — primed castings are supplied ready for a proper topcoat once fixed, matched to your specification. Black finish arrives ready to fix with no further painting needed, though it can still be overpainted later.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow is cast iron guttering fixed?\u003c\/strong\u003e Half round profiles hang from fascia brackets at standard 915mm centres; ogee profiles typically fix directly to the fascia board. Downpipes are secured with pipe nails or brackets at each socket and mid-length. Always follow the fitting manufacturer's fixing centres for wind loading in your area.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between plain and eared downpipe?\u003c\/strong\u003e Eared downpipe has cast lugs at the socket for a screw-fixed wall strap — the traditional heritage fixing method. Plain downpipe is fixed with separate pipe brackets. Match whichever your existing system or specification calls for.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs cast iron heavier to install than aluminium?\u003c\/strong\u003e Considerably — allow for proper support and expect two-person handling on longer runs and downpipe lengths. This is a genuine strength of the material for longevity, but plan installation accordingly.\u003c\/p\u003e\n\u003cp\u003eFitting a period property?
