ASTM A761/A761M is the ASTM standard that covers corrugated steel structural plate, zinc-coated, for field-bolted pipe, pipe-arches, and arches. It is relevant when projects need a defined specification for steel plate components that are assembled in the field and protected with zinc coating. By setting a clear technical basis for these structural forms, the standard supports consistent product selection, procurement, and quality expectations for engineered drainage and structural applications.

Purpose of ASTM A761/A761M

The purpose of this specification is to define requirements for corrugated steel structural plate used in field-bolted assemblies for pipe, pipe-arches, and arches. It provides a common reference for material and product conformance so that buyers, engineers, and manufacturers can align on the expected characteristics of zinc-coated steel plate. In practice, ASTM A761/A761M helps reduce ambiguity during ordering, fabrication, inspection, and acceptance of these structural components.

Common use cases of ASTM A761/A761M

This standard is commonly used for projects involving corrugated steel structural plate systems that are assembled on site into pipe, pipe-arches, or arches. These applications may include drainage, culvert, or other buried structural installations where field bolting is part of the construction method. ASTM A761/A761M is especially useful when specifying zinc-coated steel plate components that must fit together reliably during installation and meet a defined product specification.

Why ASTM A761/A761M matters

ASTM A761/A761M matters because it gives project teams a clear benchmark for product evaluation and compliance. A recognized ASTM standard supports more consistent purchasing decisions, better quality control, and more straightforward inspection of corrugated steel structural plate assemblies. For field-bolted installations, that consistency can help reduce installation issues, improve coordination between suppliers and contractors, and support risk reduction in the specification process.
