Cast Iron is a widely used metal in the drainage industry, its resistance to corrosion permits extended use under extreme conditions. Castings are surface coated to provide protection, paint will gradually wear off and is replaceable; oxidisation (surface rusting) is a natural process which does not weaken the material. A zinc anti-corrosion coating is applied to certain castings by sherardizing. Used for bodies, membrane clamping collars, threaded pipework adaptors and accessories such as extensions.

Ductile Iron is a versatile and strong material, Ductile Iron is a type of cast iron known for its impact and fatigue resistance, elongation, and wear resistance due to the spherical (round) graphite structures in the metal. Used for Gratings, Ductile Iron provides a long durable service in high traffic areas. A zinc anti-corrosion coating is applied by sherardizing.

Mild steel is a ferrous metal made from iron and carbon, It’s a malleable material that is easy to work with and makes it ideal for use in fabricated and machined parts. Used for pipe adaptors and couplings for connections to pipework.

Nickel Bronze is a cast alloy with a fine grain effect which blends well with most floor finishes. The nickel and copper content makes it a very durable material and is suited to a long-life service. When left, the material will gradually tarnish to a darker bronze but will keep its high lustre finish if cleaned/polished. Used for Gratings, Rodding Eyes and funnels.

Certain plastics provide a high degree of resistance to heat, chemical
and abrasion resistance. Components such as removable traps, dip tubes, extensions and threaded pipework adaptors use a range of Polypropylene and ABS plastic.

Stainless Steel is a corrosion-resistant metal containing significant amounts of nickel and chromium; Grade 304 stainless steel is used as standard, which is suitable for general use in and around buildings including food and hygiene applications. In areas with more aggressive environments, such as swimming pools or marine applications, grade 316 is available on request. Used for bodies, gratings, funnels, rodding eyes, filter buckets and fixings.
