ASTM A1105 is the ASTM standard for Corrugated Steel Manhole Assemblies, providing a technical reference for this type of utility structure. It helps define the expectations used when evaluating materials, construction, and overall product consistency for manhole assemblies made from corrugated steel. For buyers, engineers, and specifiers, the standard matters because it supports clearer procurement, better product comparison, and more reliable compliance decisions.

Purpose of ASTM A1105

The purpose of ASTM A1105 is to establish a recognized specification for corrugated steel manhole assemblies. As a standards document, it gives manufacturers and purchasers a common basis for describing the product and checking whether it meets applicable requirements. In practice, this kind of specification helps guide material selection, fabrication expectations, and quality control considerations. It is especially useful where consistent performance and technical clarity are important for infrastructure components.

Common use cases of ASTM A1105

ASTM A1105 is commonly used when specifying, reviewing, or procuring corrugated steel manhole assemblies for drainage, utility, or related civil infrastructure applications. It may be referenced by engineers, contractors, manufacturers, and purchasing teams during product selection and submittal review. The standard is also useful in technical documentation and compliance workflows where a clear specification is needed to support consistent fabrication and product acceptance.

Why ASTM A1105 matters

This standard matters because it helps reduce ambiguity in product requirements for corrugated steel manhole assemblies. A shared ASTM reference supports more consistent communication between design teams, suppliers, and inspectors. It can also help streamline evaluation, improve quality control, and lower the risk of ordering products that do not align with project expectations. For infrastructure procurement, ASTM A1105 provides a practical benchmark for technical and compliance review.
