Cast Iron Manhole Rings

CAST IRON SPECIFICATION    >>>

MATERIAL: Casting materials conform to specification ASTM-A48 Class 30B, Gray Cast Iron, unless otherwise specified
APPEARANCE: Castings are free from blowholes, shrinkage or other imperfections not true to pattern.
MANUFACTURING: Castings are manufactured with critical dimensions conforming to those specified on respective data sheets and drawings. Critical dimensions are defined as those that effect the load bearing capacity, interchangeability and drainage opening where applicable. Noncritical dimensions may change slightly to facilitate proper molding and casting technique. We reserve the right to make modifications to these products as required without notification.
TOLERANCES: Casting Tolerances, unless otherwise specified, are plus or minus 1/16 inch, and an additional plus or minus 1/16 inch per foot of dimension. Notwithstanding these tolerances, all frames, covers, grates and curb hoods of the same nominal size are interchangeable.
MACHINING: Bearing surfaces of circular heavy and medium duty manhole rings, covers and grates are machined to insure proper fit and prevent rattling.
WEIGHTS: Casting weights are approximate and shall be within plus or minus 5% of catalog published weight.
PAINT: Castings are supplied unpainted as a standard (See U.S. Foundry's No Paint Policy). For special paint applications, contact our customer service department.
