ISO 24259:2022

Overview

ISO 24259:2022 - Steel Strapping for Packaging sets international criteria for the design, manufacture, testing, and logistics of steel strapping used in packaging applications. Developed by ISO Technical Committee 122 (Packaging), this standard defines the classification, dimensions, shape, technical requirements, inspection rules, testing methods, marking, ordering information, and logistics related to steel strapping. Applicable to packaging operations in sectors such as metallic materials, glass, light industrial products, and general logistics, ISO 24259:2022 ensures the quality and reliability of steel strapping products across industries and global supply chains.

Key Topics

Classification

Steel strapping is classified by:

• Tensile Strength: Regular, High, and Super High, enabling selection based on load requirements.
• Surface Finish: Options include Bright, Blue and Waxed, Painted and Waxed, and Zinc Coated, offering different levels of corrosion resistance and handling properties.
• Wound Type: Ribbon and Oscillated, determining coil arrangement for compatibility with various packaging systems.

Dimensions and Tolerances

• Nominal widths and thicknesses suitable for multiple packaging needs.
• Strict dimensional and shape tolerances (for camber, flatness, and twist) to ensure reliable performance and compatibility with automated packaging machinery.

Technical Requirements

• Mechanical Properties: Defined tensile strength and elongation parameters for each classification.
• Appearance Quality: Surface must be smooth and free from defects such as rust, burrs, and incomplete coatings.
• Corrosion Resistance: Zinc-coated steel strapping is tested to withstand corrosion under specified conditions.

Inspection and Testing

• Methods for verifying size, mechanical performance, surface finish, and coating thickness.
• Testing includes tensile testing (referencing ISO 6892-1), coating thickness checks, and corrosion resistance tests (in accordance with ISO 9227).

Marking and Ordering

• Minimum marking requirements: manufacturer information, standard reference (ISO 24259), product dimensions, tensile and surface classifications, wound type, and lot/production data.
• Detailed ordering information to facilitate accurate procurement and specification compliance.

Logistics and Packaging

• Guidelines for safe handling, waterproof and moisture-proof transport, and storage.
• Recommendations for coil packaging (individual and bulk), including use of straps, wrapping materials, and corrosion inhibitors for enhanced product protection.

Applications

Steel strapping compliant with ISO 24259:2022 is ideal for:

• Securing and bundling: Used widely to contain and stabilize metallic materials, glass, and light industrial products during storage and shipping.
• Heavy-duty logistics: Ensures the safe transport of large and heavy goods by providing high-strength reinforcement.
• Industrial packaging lines: Compatible with both manual and automated strapping machines.
• Export packaging: Meets global requirements for durability and traceability, supporting international trade.

Adopting ISO 24259:2022 supports standardization, reduces risk of product damage, and facilitates regulatory compliance throughout the packaging and logistics supply chain.
