In modern geotechnical engineering and
infrastructure safety systems, steel
wire rope net panels and rolls have become essential components. Used
predominantly for slope stabilization,
rockfall protection, and debris flow mitigation, these flexible
protective structures are deployed across roadways, railways, construction
sites, and mining areas. Their function is critical—safeguarding lives,
property, and infrastructure from natural hazards.
With the growing emphasis on structural safety and standardization, the Ministry of Commerce and Industry has issued a draft Quality Control Order (QCO), 2025, making BIS certification mandatory for steel wire rope net panels and rolls. This certification ensures compliance with the Indian Standard IS/ISO 17746:2016, which defines the essential requirements, testing methods, and quality specifications for these products.
Steel wire rope nets are constructed
using metallic-coated steel wire ropes,
configured in either panel or roll form. These nets form a flexible yet strong
mesh that adapts to irregular terrain and absorbs dynamic forces from falling
rocks or debris. Their high tensile strength and corrosion resistance make them
particularly suitable for long-term outdoor installations in harsh
environmental conditions.
The panel form of rope nets is pre-assembled and used for precise applications such as hanging net systems or tensioned barriers, while rolls are generally more flexible and adaptable to a variety of site conditions. Both formats provide essential protection in areas where traditional rigid barriers or concrete structures are either impractical or ineffective.
The Indian Standard IS/ISO 17746:2016, titled “Steel Wire Rope Net Panels and Rolls —
Definitions and Specifications”, is aligned with the international ISO
standard and establishes uniform quality benchmarks for these safety-critical
products.
This standard applies to:
The standard includes definitions, structural requirements, materials, coating specifications, and test methods, ensuring that the net panels and rolls meet critical performance parameters.
To meet the requirements of IS/ISO
17746:2016 and qualify for BIS
certification, steel wire rope net panels and rolls must undergo rigorous
testing. These tests evaluate both the mechanical
integrity and coating quality of
the wire rope materials. Some of the crucial tests include:
Additionally, dimensional tolerances, wire rope diameters, net aperture sizes, and mesh configurations are also checked for conformity with the design specifications outlined in the standard.
Under the proposed Quality Control Order (QCO), 2025,
steel wire rope net panels and rolls must obtain BIS certification before being manufactured, imported, or sold in
the Indian market. This move is part of the government’s broader effort to
enhance infrastructure safety by standardizing construction materials and
enforcing quality benchmarks.
Key aspects of the BIS certification
process include:
The order excludes goods that are
manufactured in India exclusively for export, allowing exporters to continue
meeting the specific standards of foreign markets.
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.
Steel wire rope net panels and rolls
are not decorative accessories—they serve as the first line of defense in preventing fatalities, asset loss, and
infrastructure failure due to natural hazards. A failure in the performance of
such components can result in devastating outcomes. The BIS certification ensures that only verified, high-quality products
are installed in critical infrastructure projects.
For infrastructure developers, public works departments, and private contractors, using BIS-certified materials ensures not only compliance with national regulations but also instills trust among stakeholders. It also facilitates smoother project approvals, especially in government-funded works or those involving environmental clearances.
With India’s expanding road and rail
networks cutting through hilly and geologically unstable terrain, the demand
for high-performance protective systems like steel wire rope nets is steadily
increasing. The implementation of BIS
certification under IS/ISO 17746:2016 marks a significant step toward
enhancing safety, reliability, and uniformity across all such installations.
Manufacturers and suppliers must act
swiftly to align their production with the BIS standards to remain competitive
and legally compliant in the Indian market.
