All our strip drains are manufactured from 316L Grade Marine Stainless Steel. To add the perfect finish to our drains, we use specialist equipment to electropolish the stainless steel to eliminate burrs and uneven surfaces to produce a superior surface finish.
Electropolishing¹, also known as
Is a process we use to reduce the roughness of the surface of our stainless steel drain products. It polishes and deburrs the surface of the metal, used in place of abrasive fine polishing, as a superior result is achieved.
The drain is placed in an electrolyte bath, which acts as the anode, then attached to a DC (Direct Current) power source positive terminal. The negative terminal is attached to the cathode. The electrical current is then passed from the anode to the cathode, oxidising the surface metal. At the cathode, a hydrogen producing reduction reaction occurs.
The electrolyte solution is usually made from Sulphuric and Phosphoric acids and is high in viscosity.
For this process to achieve a superior polish, the protruding parts that need to be removed must dissolve faster than the main body of the metal.
The benefits of using electropolishing for stainless strip drains are:
Electropolishing creates a superior finish for stainless steel drains, and offers ease of polishing complex shapes such as a wedgewire strip drain.
Electropolished finishes offer a better result than abrasive polishing, due to the efficiency of the electrolyte process.
