Copper vs Zinc vs Stainless Steel Guttering: Which to Choose

Copper, zinc and stainless steel guttering all outlast PVC and painted metal by decades. They need no painting and suit period properties, conservation areas and contemporary architecture alike. This guide compares the metals in the Metal Gutta range, which is made in Hampshire, UK, to help you choose.

At a glance

Metal Appearance Best for
Copper (0.6mm) Bright copper, weathering to brown and then a green patina Period and listed buildings, statement projects; run-off helps inhibit moss
Natural Zinc Silver-blue, weathering to dark grey Matching VM Zinc or Rheinzink roofing and cladding
Quartz Zinc Pre-weathered mid-grey from day one Contemporary homes wanting a consistent grey finish straight away
Stainless Steel (grade 304) Slightly shiny mill finish The lowest-maintenance option, modern designs

Lifespan

All four metals have an expected lifespan of 70–100+ years and never need painting. They can cost more up front than PVC or aluminium, but they can outlast several replacement cycles of those materials.

Profiles and sizes

  • Standard Half Round 125mm – 125mm wide x 76mm deep
  • Large Half Round 165mm – 165mm wide x 102mm deep
  • Standard Ogee 125mm – 125mm wide x 97mm deep
  • Large Ogee 145mm – 145mm wide x 137mm deep
  • Standard Box 80mm – 80mm wide x 75mm deep
  • Large Box 115mm – 115mm wide x 100mm deep

Availability varies by metal. The Metal Gutta Quick Order tool shows which profiles and downpipes come in each metal and estimates the brackets, joints and fittings for your run.

Don't mix copper with zinc

Use one metal throughout a system. Rainwater running off copper corrodes zinc, so never let copper drain onto zinc gutters, roofs or flashings.

Fitting

Half round lengths overlap 30–50mm without a separate joint. Ogee and box profiles use internal joints. Each metal has its own fitting instructions, and these are linked as PDFs on every Metal Gutta product page.

Delivery and lead times

Metal Gutta products are made to order and delivered direct to site from the manufacturer. Fittings typically take 5–10 working days.
