stainless steel aluminum clad metals for dual/three layer hot plate induction cooktop, diffuser plate & steel plate armor

FASTAL Griddles

FASTAL clad plate is our premium quality, three-layered product delivering the highest performance for industrial griddles. This tri-metal composite consists of an aluminum core metalurgically bonded between two sheets of stainless steel.
Advantages
  • Excellent hear transfer – 5x faster than carbon steel
  • Even heat distribution over the entire plate for optimum cooking uniformity
  • 30% lighter than carbon steel for easy installation
  • Easy to clean and low maintenance
  • Outstanding resilience to frequent temperature changes
  • Reduced sticking and flavour transfer

Typical Properties of Stainless Steel/Aluminum/Stainless Steel

Our three-layer material provides better ductility and strength than pure aluminum. It also achieves superior heat conductivity than stainless steel. The same benefits apply to our thicker plates.
