ANSI Standards

Understanding ANSI's role in US manufacturing standards.

ANSI coordinates the U.S. voluntary consensus standards system, accrediting the procedures of standard developing organizations like NAAMM and ASTM. Our perforated metal, expanded metal, and bar grating solutions conform to accredited technical specifications for predictable load ratings and structural integrity.

Core Clarification

The role of ANSI in US manufacturing

The American National Standards Institute (ANSI) is a non-profit coordinator and accrediting body. ANSI does not author or publish standalone product codes for perforated metal, expanded mesh, or bar grating directly.

Instead, ANSI accredits specialized Standards Developing Organizations (SDOs) — including ASTM International and the American Welding Society (AWS). Mutual Metal manufactures and supplies industrial metal products built to these ANSI-accredited standard frameworks to ensure verifiable metallurgical chemistry, mechanical load capacities, and weld performance.

Umbrella accreditation body
ANSI Coordination & Accreditation
ANSI oversees and validates voluntary consensus standards organizations across the United States, maintaining integrity and procedural rigor without drafting product-specific manufacturing rules.
Material & alloy testing standards
ASTM Material Specifications
Our raw materials, tensile thresholds, and chemical compositions comply with standards developed by ASTM International, an ANSI-accredited development organization.
Structural & fusion integrity
AWS Welding & Fabrication
Welded bar grating and joined structural components follow welding and inspection benchmarks established by the American Welding Society under the ANSI consensus system.

Engineering submittals & standard adherence

Every project specification is matched against applicable accredited criteria during the quotation and engineering review.

Verified US Supply
Accreditation vs. Direct Publishing

ANSI validates the development process of standards rather than issuing specific metal product dimensions.

Verified Consensus Systems

Technical requirements reflect multi-party consensus across manufacturers, engineers, and testing bodies.

Specification Alignment

Project submittals reference specific ASTM and AWS designations appropriate to each order requirement.
