ASTM A1113/A1113M is the ASTM standard that addresses corrugated steel structural plate with a polymer coating for field-bolted pipe, pipe-arches, and arches. It is intended to support consistent material and product expectations for these structural applications, helping buyers, engineers, and fabricators evaluate conformance with a recognized specification. By defining the product type and general technical framework, the standard helps improve clarity in procurement, quality control, and project documentation.

What is ASTM A1113/A1113M?

ASTM A1113/A1113M is a product specification for corrugated steel structural plate that includes a polymer-coated finish and is designed for field-bolted assembly. The standard title indicates its focus on pipe, pipe-arches, and arches, so its role is to establish a common reference for this type of structural steel product. As an ASTM standard, it supports consistent evaluation of the plate material and configuration used in these built-up structures, which may be important for specification writing and acceptance checks.

Where is ASTM A1113/A1113M used?

This standard is commonly used where corrugated steel structural plate is selected for assembled pipe, pipe-arch, or arch installations. It is relevant to projects that rely on field-bolted components and a polymer-coated steel surface for the specified structure type. ASTM A1113/A1113M is useful in engineering, purchasing, and construction workflows when a project requires a clear product specification for coated structural plate and a consistent basis for ordering, inspection, and documentation.

Why is ASTM A1113/A1113M important?

ASTM A1113/A1113M matters because it gives a defined specification for a specialized structural plate product, reducing ambiguity during design and procurement. For teams comparing materials or reviewing submittals, the standard helps support consistent quality expectations and more reliable product evaluation. It also assists with compliance by providing a recognized reference point for field-bolted corrugated steel structural plate used in pipe and arch applications. That consistency can help lower risk in purchasing and project execution.
