| MATERIALS, FINISHES AND TOP
LOADING CLASSIFICATIONS Cast Iron Painted: Gray cast iron has long been a satisfactory material for plumbing fittings and equipment. The inherent fluidity of the metal allows the casting of intricate shapes and its resistance to corrosion permits extended use under extreme conditions. The gray iron commonly used in plumbing fittings is a relatively high silicon iron with a tensile strength in the range of 2l,O0O pounds per square inch. The iron is sufficiently close grained to withstand hydraulic pressure of 250 pounds per square inch. Ductile Iron: A material developed to provide the strength of steel without sacrificing corrosion resistance and fluidity. This material ductile or nodular iron has tensile strength upwards of 75,000 pounds per square inch. Yield strength and elongation are equal or superior to many carbon steels. The material can be welded when heat-treated. |
| Metal | Specifications | Tensile Strength (psi) | Yield Strength (psi) | Elongation | Modulus of Elasticity (psi) |
| Cast Iron | - | 21,000 | NIL | NIL | 16x100° |
| Ductile Iron | 60-42-10 | 60/80,000 | 42/60,000 | 10% to 25% | 24x100° |
Wade-Paint: Wade cast iron is furnished standard with a high quantity enamel paint coating which has an attractive appearance and a high resistance to rusting. This coating is burnt red in a appearance. Galvanized Iron: Wade galvanizing is a process of applying a zinc coating to a thoroughly cleaned fitting. This coating contains approximately 95% zinc in a hot dip process. Wade galvanizing is recommended wherever discoloration caused by oxidation is objectionable. Galvanizing may be desirable in coastal areas where corrosive atmospheres may be encountered. Acid Resisting Enamel (A.R.E): Wade A.R.E. is a white epoxy powder coating thermochemically applied to a thoroughly cleaned cast iron product. It provides a high gloss finish that is hard, tough, provides superior corrosion resistance, and is ideally suited for sanitation purposes. As this is an epoxy, it is not recommended for outdoor applications where gloss retention is required. Acid Resisting Coating: Wade interceptors normally come with a base coating that provides good corrosion resistance, and is inert to most chemicals encountered in DWV systems. Stainless Steel: Wade stainless steel floor sinks are normally supplied in 16 ga. Type 304. Stainless steel provides a superior sanitary finish. Aluminum: Light weight, exceptional strength and corrosion resistance make aluminum ideal for drain components, especially sediment buckets and secondary strainers. Commonly used with A.R.E. coated drains because the possibility of chipping is minimized. Nickel Bronze: Nickel bronze is Wade's name for C99700 white manganese brass. Its tensile strength ranges from 40,000 to 60,000 pounds per square inch. This particular material maintains its appearance despite abuse or exposure. Nickel bronze is preferred to chromium plated brass whenever lasting appearance is required and should be used in all finished floor applications. Top Loading Classification: Grates and covers on Wade products carry a safe live load rating as follows:
*Shower drains (1100 Series) are rated (LD) Light Duty For general classification only. These drains are for foot traffic only (300 lbs. max.) These live load ratings were established by testing methods outlined in ANSI A112.21.1M. The test procedure is as follows: A 3.5" (89mm) diameter platen is applied to the center of the grate or cover. Loading is applied slowly so that point of failure can be observed. Point of failure is established for cast iron or ductile iron when the first fracture appears. For bronze materials, the point of failure is the load at which a permanent set is achieved greater than 2% of the longest outside dimension. The maximum safe live load is computed by dividing the load at failure by two (a two times safety factor). |
