Hebei Slope Protection Net Supply – Custom Sizes, Lead Time and Technical Support

Published on 2026-10-11

Hengshui Zhanhe Engineering Rubber Co., Ltd. supplies slope protection net and related engineering rubber products to contractors, distributors and infrastructure projects worldwide. A flexible steel wire net system that either stabilises the slope surface or intercepts falling rock, covering both active and passive SNS systems.

This article explains the working principle, main types, typical applications, installation points, selection criteria, standards and frequently asked questions about slope protection net, and is intended for engineers, purchasers and project managers.

1. What Is Slope Protection Net?

A flexible steel wire net system that either stabilises the slope surface or intercepts falling rock, covering both active and passive SNS systems.

Working principle: The product works through elastic deformation and mechanical interlock to provide reliable sealing or load transfer.

2. Main Types

• Active net (GPS / GAR series): a tensioned cover net that restrains surface weathering, spalling and shallow sliding.
• Passive net (RX / RXI series): an interception barrier at the toe or mid-slope, selected by energy level from 250 to 5000 kJ.
• Ring net (RXI): interlocking steel rings giving large deformation and energy dissipation for high-energy rockfall.
• Guiding / curtain net: directs falling rock into a preset catchment area instead of stopping it.

3. Typical Applications

• Rockfall and collapse control on cutting slopes of highways and railways, especially above live traffic.
• Geohazard treatment on mining and quarry faces, including closed pit slopes.
• Protection of slopes at hydropower stations, transmission line corridors and pipeline routes.
• Safety protection behind scenic walkways, villages and schools.

4. Installation and Construction Points

1. Build working platforms and safety lines, then clear the slope from top down, dealing with loose rock first.
2. Set out anchor positions to the drawing, drill to the specified depth and diameter, clean holes, grout and cure to strength.
3. Tension boundary and support ropes to form the grid, fixing rope ends with the specified number and spacing of clamps.
4. Lay the grid net and cable net from the top downward, sewing panels together so the net follows the slope surface.
5. For passive systems, erect the posts, tension the upper and lower support ropes and lateral anchor ropes, then hang the ring net and fit the energy dissipating rings.
6. Check anchor pull-out test results, net tension and ring orientation; carry out rockfall trials where required by the supervisor.

5. Selection Guide

• Confirm the design displacement, load grade and service environment before ordering.
• Select material grade according to temperature range, medium and durability requirements.
• Provide drawings or a specification list so that the manufacturer can verify sizes.

6. Standards and Quality Control

Slope Protection Net is manufactured and inspected according to applicable national and industry standards. Hengshui Zhanhe Engineering Rubber Co., Ltd. carries out batch inspection before delivery, and inspection certificates together with third-party test reports (where required by the project) can be provided.

Typical standards applied to this product family include Chinese national and transportation industry standards; equivalent international standards can be referenced upon request.

7. FAQ

Q: How do I choose between an active and a passive system?

A: It depends on rockfall size and slope condition. For broadly weathered slopes with small blocks, an active cover net is more economical. For steep, high slopes with large blocks and something to protect below, install a passive barrier at the toe or mid-slope. Steep high slopes often use active above and passive below.

Q: What does the energy level of a passive net mean?

A: It is the impact energy the system can reliably arrest, in kJ, commonly graded from 250 kJ to 5000 kJ. Estimate the energy from block mass and arrival velocity and choose a level above the calculated value with a margin, rather than judging by block size alone.

Q: What do the energy dissipating rings do?

A: They yield plastically before the net and posts, absorbing part of the impact energy and limiting the force transmitted to the anchor ropes and posts so the anchorage is not pulled out. Deformed rings cannot be reused and must be replaced after an impact.

8. Price Factors

Active nets are priced by area, commonly 80-200 RMB per square metre, driven by anchor length and density, net specification and the difficulty of the terrain. Passive systems are priced by energy level per linear metre, with a 500 kJ class typically 800-1500 RMB per metre. Labour, plant and material transport such as cableways or secondary handling often exceed the cost of the materials themselves.

Packing: standard export packing (woven bags, pallets or wooden cases). Delivery terms: EXW, FOB, CFR, CIF or DAP as agreed. Payment terms: T/T, L/C or other terms subject to negotiation.
