Schedule 40 pipe, Galvanized
Schedule 40 pipe for use as end, corner or line posts, and rails, for commercial, industrial and institutional installations Schedule 40 pipe is the historically used material for this purpose. The requirements for this material are contained in various government specifications for use in road, dock, airport, housing, forestry, and military installations.
Schedule 40 pipe is typically used in installations which incorporate zinc-coated or aluminum-coated steel chain link fence fabric, although it may be specified for use with other types of fabric, i.e. PVC coated.

Galvanized Steel Framework:
The informationcontainedhereinfor hot- dipped galvanized welded steel pipe covers two options of ASTM F1083 hot-dipped galvanized schedule 40 welded steel pipe, Regular Grade and High Strength Grade. The accompanying tables show the different options have the same dimensions, wall thickness, weight per linear foot, galvanized coating and tolerances. The Grade signifies the yield strength of the schedule 40 pipe.
Grade Yield Strength:
Regular Grade - Yield Strength, min.30,000 psi High Strength Grade - Yield Strength, min.50,000 psi
The Pipe shall be coated inside and out by the hot-dip process. The average weight of zinc coating shall be not less than 1.8 oz/ft2 of the outside surface and 1.8 oz/ ft2 of the inside surface. A 2.0 oz/ft2 zinc coating weight is available upon request. A conversion coating is also applied to the interior and exterior surfaces to protect against corrosion and white rust.
Periodic inspection is recommended but no routine maintenance is required.
