BIS Certification for Steel Wire Ring Net Panels IS/ISO 17745:2016

In mountainous regions and areas vulnerable to natural hazards like rockfalls, landslides, debris flows, or even snow avalanches, safety measures must be both reliable and robust. One of the most critical components in these protective systems is the Steel Wire Ring Net Panel—a flexible yet high-strength solution that helps mitigate risks from falling rocks and debris. These panels form the backbone of many geotechnical safety systems and infrastructure projects, particularly those built along roads, highways, railways, urban slopes, and mining sites.

Recognizing their importance in civil and structural safety, the Ministry of Commerce and Industry has proposed a Quality Control Order (QCO), 2025, making it mandatory for manufacturers and importers to obtain BIS certification for steel wire ring net panels under Indian Standard IS/ISO 17745:2016.

Understanding Steel Wire Ring Net Panels

Steel wire ring net panels are engineered from numerous high-tensile steel wire rings, typically formed into circular loops and interlinked in a chainmail-like mesh. This configuration offers excellent flexibility while maintaining exceptional tensile and impact strength. These panels are designed to absorb and redistribute the kinetic energy of rockfalls or fast-moving debris, thereby preventing catastrophic damage to infrastructure and reducing risk to human life.

Because they are exposed to environmental stressors like rain, snow, UV radiation, and chemical corrosion, the wires used are often metallic-coated—with either zinc or advanced Zn-Al alloy coatings—to prolong operational life and enhance resistance against corrosion and wear.

What IS/ISO 17745:2016 Specifies

IS/ISO 17745:2016 is an Indian adoption of the international ISO standard that lays out technical specifications for steel wire ring net panels. It includes criteria that ensure the materials used, structural design, and mechanical performance are all aligned with international safety and durability standards.

This standard applies to metallic-coated or advanced metallic-coated steel wire ring net panels used for:

     ● Rockfall and landslide mitigation
     ● Debris flow control systems
     ● Snow avalanche barriers
     ● Slope retention for highways, railways, tunnels, and mines
     ● Urban slope stabilization and roadside protective installations

Key technical aspects covered by IS/ISO 17745:2016 include:

● Wire material and coating properties, including minimum tensile strength, elongation, and corrosion resistance

● Ring construction—such as outer diameter, cross-sectional wire diameter, and number of wraps

● Panel layout, including spacing and joining of rings

● Dimensional tolerances, strength requirements, and performance under impact loads

● Testing procedures for durability, flexibility, and mechanical resilience

● Marking and labeling, which ensures traceability and compliance during inspections

The standard is comprehensive in its approach and ensures that the ring net panels used in safety-critical environments can endure extreme weather and dynamic forces over long operational periods.

Why BIS Certification Is Now Mandatory

The Indian government’s move to mandate BIS certification for steel wire ring net panels underscores its commitment to improving safety in infrastructure and environmental protection projects. Under the Steel Wire Ropes, Strands, Ring Net Panels, Rope Net Panels and Rolls (Quality Control) Order, 2025, any steel wire ring net panels manufactured or imported into India must conform to IS/ISO 17745:2016 and be approved by BIS before being sold or used.

This means manufacturers must undergo the BIS certification process, which includes:

●Factory inspection and audit to evaluate production capabilities and quality management systems
● Testing of product samples in BIS-recognized laboratories
● Compliance with labeling and documentation norms as per BIS regulations
● Surveillance and reassessment to ensure ongoing conformity

Once certification is granted, manufacturers are authorized to use the ISI Mark, which signifies compliance with Indian Standards and builds trust among consumers, project engineers, and government agencies.

BIS Certification Process for Locknuts and Locking Devices

BIS certification under this standard involves a rigorous conformity assessment process to ensure product quality and adherence to regulatory norms. The steps typically include:

  1. Filing an application to BIS with detailed product specifications, quality management system documents, and test reports.

  2. Factory inspection by BIS auditors to verify manufacturing capability, equipment, testing infrastructure, and quality controls.

  3. Product testing of locknuts and locking devices at BIS-recognized laboratories to confirm compliance with IS 16605 (Part 2):2018.

  4. Grant of BIS License upon successful audit and testing.

  5. Ongoing surveillance by BIS to ensure continued compliance through periodic inspections and testing of market samples.

The Importance of Compliance

Given the role these panels play in saving lives and protecting infrastructure, ensuring that only certified, high-quality panels are used in critical applications is of utmost importance. Non-compliant or substandard ring net panels can fail under stress, leading to potentially disastrous outcomes.

BIS certification under IS/ISO 17745:2016 ensures uniformity, reliability, and durability—especially in high-risk areas such as Himalayan transport corridors, mining zones, and regions with extreme weather conditions. Moreover, the presence of certified safety materials enhances the credibility of infrastructure developers and may be essential in securing government contracts or environmental clearances.

Conclusion

Steel wire ring net panels may seem like a modest component of a larger infrastructure safety system, but they perform a life-saving role. As India continues to invest in infrastructure expansion and disaster mitigation, ensuring the quality and reliability of every safety component becomes non-negotiable.

The BIS certification for steel wire ring net panels, based on IS/ISO 17745:2016, sets a new benchmark in structural safety and engineering standards. Manufacturers, suppliers, and project developers must proactively adapt to this regulatory change to maintain market access and meet compliance expectations.
