Stainless Steel

• installation top edge height is 865mm
• stainless still requires earth continuity cross bonding
• the most popular on the market–in fact, according to Franke 70% of all sinks are made using stainless steel.
• Stainless steel is classified in terms of gauge:
  • Lower gauge steel is heavier
  • higher gauge is lighter
• residential sinks are usually between 18 and 22. In terms of inches, this means the steel sheeting used to make the sinks has a thickness that ranges from .048″ to .030″.
• a heavier gauge sink can be slightly more resistant to denting and is typically less noisy
• it can be difficult to keep them looking immaculately clean at all times. However, they offer excellent resistance to heat and stains.
• waste size: 92mm
• Waste pipe min size is 40mm

Cast Iron

• cast iron sinks receive a heavy porcelain enamel finish
  • porcelain enamel finish used on cast iron sinks isn’t merely paint–it’s actually melted glass that has been fused to the bare iron.
• Porcelain enamels also have good resistance to light and fading
• It’s heavy. An average-sized iron sink can easily weigh 100 lbs or more, which is 2-3 times as much as most stainless steel sinks
• Cast iron can be much more expensive than stainless steel
• the enameling of a cast iron sink can chip, but modern porcelain enamel is strong

Composite

• usually granite or quartz composite
  • made by combining crushed granite or quartz with a resin filler
  • it’s usually around 70%-80% rock and 20%-30% resin
• highly resistant to stains and scratching
• granite tends to hold up better than quartz

Fireclay

• made by molding a ceramic clay into the shape of the sink and allowing it to dry at a high temperature for a period of up to 40 hours
• fireclay sinks are generally regarded as being more durable than cast iron
• the enamel can chip from the impact of a dropped pot or glass
• Fireclay kitchen sinks fall on the expensive end of the spectrum.
• the material is most commonly associated with farm sinks (also known as farmhouse or apron sinks)
• Many people choose fireclay farmhouse sinks for their traditional but timeless styling
