SECTION 725 - MISCELLANEOUS METALS AND PLASTICS
725-01 Copper Flashing
SCOPE. This specification covers the material requirements for copper flashing. MATERIAL REQUIREMENTS. Sheet copper for flashing shall be rolled from copper fulfilling the requirements of ASTM B5. This sheet metal shall be cold rolled soft copper. BASIS OF ACCEPTANCE. Acceptance of this material will be based on the manufacturer's certification that the material meets the specification requirements.
725-02 Steps for Manholes
SCOPE. This specification covers the material requirements for steps used in manholes. GENERAL. The minimum design live load, for steps, appurtenances and fastenings, shall be a single concentrated load of 800 pounds. The live loads imposed by persons occupying the steps shall be considered to be concentrated at such points as will cause the maximum stress in the structural member being considered. Steps shall be designed so a worker's foot cannot slide off the end. The minimum length of the rungs shall be 10 inches. Whenever a combination of dissimilar types of metals are used in the manufacture of steps, appurtenances and fastenings, the materials shall be treated to prevent deleterious effects. MATERIAL REQUIREMENTS. Manhole steps shall be fabricated from one of the following:
A.Ferrous Metal. Steps shall conform to one of the following requirements: Iron Castings Class 25A, 715-05 Malleable Iron Castings Grade 35018, 715-09 Steel ASTM A575, Grade M 1020 galvanized in accordance with '719- 01, Type 1. The steps shall have a minimum cross sectional dimension of 1 inch exclusive of any coatings placed on them.
B.Non-Ferrous Metal. Steps shall conform to the following requirements: Aluminum Castings Alloy 356-T6, 715-03. Wrought Aluminum 6061-T6, 6005-T5, or 6351-T6, 715-04

NEW YORK STATE DEPARTMENT OF TRANSPORTATION Section 700 STANDARD SPECIFICATIONS (USC) January 1, 2026 VOLUME 4 When aluminum steps are used, the portion of the step which will be in direct contact with cement concrete or concrete mortar, shall be coated with a zinc chromate primer or bituminous material approved by the Materials Bureau.
C.Reinforced Plastic. Steps shall consist of polypropylene or other plastic material completely covering a steel core. The plastic may be extruded, cast, or molded into the standard size and shape manhole steps, and provide corrosion protection. The plastic material shall have the following characteristics:
1.Resistance to Salt and Caustic Solutions. Resistance to the following solutions when submerged for 30 days:
a.10% Sodium Chloride
b.10% Hydrochloric Acid
c.10% Sodium Hydroxide
d.10% Sulfuric Acid
2.Flow Point. A flow point of 320OF or greater.
3.Flexibility. It shall remain flexible over a temperature range of -22OF to +248OF upon long aging.
4.Fire Resistance. It shall be non-burning, self-extinguishing, or very slow burning. The steel core shall be not less than 1/2 inch diameter and shall have the following physical characteristics:
a.Tensile Yield, Minimum 40,000 psi
b.Tensile Strength, Minimum 70,000 psi The plastic step, when cast into a concrete block the proper depth, shall withstand a minimum load of 800 pounds applied on 1 square inch area in the center of the step without cracking or breaking the plastic coating, loosening the step in the concrete or permanently deforming the step. BASIS OF ACCEPTANCE. Manhole steps shall be accepted on the basis of the manufacturer's certification of compliance with this specification. However, the Department reserves the right to take random samples at any time for testing for compliance with the requirements of this specification.
