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.
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.
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:
Key technical aspects covered by
IS/ISO 17745:2016 include:
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.
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:
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 under this standard
involves a rigorous conformity assessment process to ensure product quality and
adherence to regulatory norms. The steps typically include:
To apply for BIS certification, manufacturers need to submit the following documents:
● Application form
● Manufacturing process details
● Quality control plan
● Test reports from BIS-approved laboratories
● Factory layout and equipment details
● Proof of business registration
● Product specifications and technical details
● Declaration of conformity to Indian standards
Additionally, manufacturers may be required to provide proof of compliance with environmental and safety regulations, depending on the specific type of product being certified.
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.
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.
