SYI Manhole Cover Series (EN 124) - Maximum load allowed for various classes
- GROUP 1: (class A 15 minimum) Test 1.5 metric ton
Material — Ductile iron and Grey iron:
- Microstructures of the two types:
- The difference between ductile iron and traditional grey iron: The addition of magnesium at the molten stage transforms the flakes of graphite which are common with the grey iron casting process and transform them into spheroidal or
nodular form. The nodular structure provides a higher tensile strength as well as a higher “strength to weight”ratio when compared with the properties inherent with grey iron manufacture.
- The benefit of ductile iron: Ductile iron high strength to weight ratio allows for the production of light weight castings that offer what can amount to a 50% weight saving over traditional grey iron.
Most of the standard sizes are available.
