BS 460:2002 is the British Standard governing cast iron rainwater goods — gutters, pipes, and fittings. It sets the dimensional tolerances, materials, and performance requirements a component must meet, so that joints seal, sections align, and the system performs as a whole rather than as isolated parts. All Tuscan Foundry Products components are manufactured to comply with BS 460:2002, which is worth citing directly in specification documents and listed building consent applications. The same manufacturing standard applies to bespoke and copy-cast work, even where the profile itself isn't from our standard range.
