IS 4093:1967 is the Indian Standard (BIS) for chain link fence for security purposes - specification. This standard specifies the requirements for materials, dimensions, and construction of chain link fencing intended for security purposes. It covers the specifications for the wire fabric, supporting posts, struts, and guidelines for proper erection and tensioning.
Specifies requirements for chain link fence intended for security purposes.
Standard Specification for Zinc-Coated Steel Chain-Link Fence Fabric
Specifies zinc-coated steel chain-link fabric, directly aligning with the core scope of IS 4093.

Key Differences
≠IS 4093:1967 is a withdrawn standard, superseded by IS 2721:2003. The international equivalents listed are current, regularly updated standards reflecting modern materials and manufacturing practices.
≠Modern standards like ASTM A392 and BS EN 10223-6 specify a wider range of coating options, including polymer (PVC) coatings and aluminum-zinc alloys, whereas IS 4093 focuses solely on two classes of hot-dip galvanizing.
≠International standards typically mandate higher minimum tensile strength for the steel wire. For example, ASTM A392 requires a minimum of 75 ksi (517 MPa), whereas IS 4093 specifies a lower range of 30-45 kgf/mm² (approximately 294-441 MPa).
≠Tolerances for manufacturing parameters such as wire diameter, mesh size, and fabric height are generally more detailed and often tighter in current international standards compared to the broader tolerances specified in the 1967 Indian standard.
Key Similarities
≈All standards are based on the fundamental construction of a chain-link fence fabric formed by helically winding and interweaving steel wires.
≈The primary method of corrosion protection specified in IS 4093, hot-dip galvanization (zinc coating), remains a principal and classifiable option in all modern international equivalents.
≈All standards define and specify the main customizable parameters for the fabric, including wire gauge (diameter), mesh size (diamond size), and the overall height of the fabric roll.
≈The specification of different selvage (edge finish) types, primarily 'knuckled' (bent over) and 'twisted' (barbed), is a common feature across all the standards.
