Standard Specification for Zinc-5 % Aluminum-Mischmetal Alloy-Coated Steel Chain-Link Fence Fabric

ABSTRACT
This specification covers the physical requirements for zinc-5 % aluminum-mischmetal (Zn-5Al-MM) alloy-coated steel chain-link fence fabric before weaving. The physical properties to which the fabric should conform are weave form, size of mesh, size of wire, height of fabric, selvage, weight of coating, workmanship, and standard length of rolls.
SCOPE
1.1 This specification covers zinc-5 % aluminum-mischmetal (Zn-5A1-MM) alloy-coated steel chain-link fence fabric, Zn-5A1-MM alloy-coated, before weaving.  
1.2 The values stated in inch-pound units are to be regarded as the standard.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview

ASTM F1345-10a(2023) is a standard specification developed by ASTM International that addresses the requirements for zinc-5% aluminum-mischmetal (Zn-5Al-MM) alloy-coated steel chain-link fence fabric, specifically before weaving. This specification defines the vital physical properties for chain-link fence fabric including wire size, mesh size, coating weight, fabric height, selvage finish, weave form, and standard roll length. These criteria ensure consistent quality and long-term durability for coated steel fencing products. The standard is designed in accordance with globally recognized principles set forth by the World Trade Organization’s TBT Committee.

Key Topics

• Material Specification: Covers chain-link fence fabric made from steel wire coated with a zinc-5% aluminum-mischmetal alloy, providing improved corrosion resistance and strength compared to traditional coatings.
• Wire and Mesh Sizes: Details specific tolerances for wire diameter and mesh size to ensure uniform weave and structural reliability.
• Coating Weight: Specifies two protection classes for coating mass:
  • Class 1: Minimum 0.6 oz/ft² (183 g/m²)
  • Class 2: Minimum 1.0 oz/ft² (305 g/m²)
• Fabric Construction:
  • Defines allowable mesh dimensions and wire gauges.
  • Ensures accurate height measurements and specifies methods for selvage finishing-knuckled, twisted, or a combination.
• Workmanship: Requires good commercial practices and prohibits excessive surface roughness, blisters, or flaking on the coating.
• Inspection and Testing: Provides guidelines for sampling, testing, and acceptance criteria for manufactured rolls to ensure product conformity.
• Packaging and Marking: Outlines standard packaging, tagging, and shipment practices in compliance with ASTM and government requirements.

Applications

This standard is widely applied in the construction and installation of security and boundary fencing for various settings, including:

• Commercial and Industrial Facilities: Where durability, strength, and corrosion resistance are critical for perimeter security.
• Recreational Areas: Such as parks, playgrounds, and sports fields, where chain-link fencing provides visibility and protection.
• Residential Properties: To delineate property lines or enclose yards while maintaining a low-maintenance barrier.
• Government and Military Installations: The specification supports procurement processes by specifying packaging, marking, and shipment in line with civil and military standards.

By meeting ASTM F1345-10a(2023) requirements, suppliers and contractors ensure consistent product quality, ease of installation, and long-term fence performance in diverse environments. The Zn-5Al-MM coating offers enhanced lifespan over traditional galvanization.

Related Standards

Entities working with or specifying chain-link fencing should be aware of several related ASTM and federal standards, including:

• ASTM A90/A90M: Test Method for Weight [Mass] of Coating on Iron and Steel Articles with Zinc or Zinc-Alloy Coatings.
• ASTM A491: Specification for Aluminum-Coated Steel Chain-Link Fence Fabric.
• ASTM A817: Specification for Metallic-Coated Steel Wire for Chain-Link Fence Fabric and Marcelled Tension Wire.
• ASTM A700: Guide for Packaging, Marking, and Loading Methods for Steel Products for Shipment.
• Federal Specifications: Fed. Std. No. 123 for civil shipment marking, MIL-STD-129 for military shipment marking, and MIL-STD-163 for preparation and storage of steel mill products.

Compliance with ASTM F1345-10a(2023) and related standards assures users and buyers of high-performance, safe, and reliable fence products suitable for a range of demanding applications.
