RNK Care Guide for Tapware

Products and their composition

RNK have main composition materials of solid brass, 304 and 316 stainless steels. 

Solid Brass 

RNK use solid brass for most of our tapware range, it is an extremely durable and suitable material for its purpose. Brass is mainly used throughout the home as it is a low traffic area and is constructed from pure brass. 

Stainless Steel 

We use stainless steel grade 304 for our indoor range and stainless-steel grade 316 for the outdoor range. These types of stainless steel are extremely versatile. The chromium found in stainless steel gives it versatility and durability making it extremely hard-wearing metals to choose from. Stainless steel is commonly used for areas which require a high level of durability for example a kitchen sinks. Stainless steel grade 316 has further corrosion resistance making it suitable for outdoor use. 

Whilst both these materials are treated using the same finishing process, the differences in the ergonomics of the material mean there may be slight variations in the colour and overall finish. All RNK products can be used in residential and non-residential environments unless the standard states otherwise. 


Product Treatment and Finish

Our products undergo one of the following colour treatments to finish the product: 

  • Advanced Electroplating Application (AEA
  • Physical Vapour Deposition – Industrial Grade (PVD) Electro Colouring System 
  • Prime Shield Lacquer Technology (PSLT)


Advanced Electroplating Application (AEA) 

When the process of electrolysis is used to coat a layer of chromium, nickel or coloured alternative aids the longevity of its life and prevents it from corrosion and general wear and tear. 

  • Chrome (AEA) 
  • Matte Black (AEA) 

Physical Vapour Deposition (PVD)

PVD is a technique which a solid material is placed in a vaporised vacuum environment which leads to pure material substrate or alloy composition coating. The coating builds bonds to the surface providing an extremely pure and high-performance protection layer. 

  • Brushed nickel (PVD) 
  • Brushed Brass (PVD) 
  • Brushed Gunmetal 
  • Brushed Copper 


Prime Shield Lacquer Technology (PSLT) 

PSLT is the process in which a dried powder is applied to a surface electrostatically and cured under high temperature, because this process elements the ability to corrade there is a less concern or rust and other cleaning related damage. 

  • White (PSLT)
