ASTM A1113/A1113M-20e1 PDF Download

ASTM A1113/A1113M-20e1 is a standard specification that provides guidelines for the manufacturing and installation of corrugated steel structural plate, polymer-coated, used in the construction of various structures such as pipes, pipe-arches, arches, underpasses, and special shapes. These structures are typically used for drainage purposes, pedestrian and vehicular underpasses, and utility tunnels.

The specification includes details about the appropriate fasteners and accessory materials that should be used in conjunction with the corrugated steel plates. However, it does not cover requirements for bedding, backfill, or the relationship between earth cover load and plate thickness of the pipe. It is important for the purchaser to consider factors such as plate thickness, type of bedding and backfill, and the corrosion and abrasion requirements of the field installation. The structural design of the corrugated steel structural plate pipe and the proper installation procedures are described in Practices A796/A796M and A807/A807M.

The standard allows for orders to be specified in either inch-pound units (A1113) or SI units (A1113M), with SI units being applicable when the material is ordered to A1113M. The specification also includes notes and footnotes that provide additional explanatory material, although these should not be considered as requirements of the specification.
