Singrauli is one of the most heavily industrialised districts in central India, and the ground conditions around its mines and power stations put steady demands on every embankment, slope and drain on site. ## Project snapshot | Parameter | Details | | --- | --- | | Project | Coal Plant Project | | Location | Singrauli, Madhya Pradesh | | Product supplied | Ocean Double Twisted Hexagonal Shaped Steel Wire Mesh | | Quantity | 140 pieces | | Supplied by | Ocean Non Wovens | | Sector | [Power and mining](https://oceangeosynthetics.com/suitable_sectors/power-and-mining/) | ## Why Singrauli is a demanding site Singrauli is often called the energy capital of India. Large opencast coal mines feed several thermal power stations in the district. That concentration of industry shapes the civil engineering. A coal plant is not a single building. It is a spread of coal handling yards, conveyor corridors, approach roads, ash handling areas, drains and embankments, much of it built on cut or filled ground. The local conditions add to the load on those structures: - **Monsoon rainfall:** most of the year’s rain falls between June and September, often in heavy bursts that send fast runoff across exposed slopes. - **Loose and disturbed ground:** overburden dumps, fill and cut faces erode quickly once vegetation is stripped. - **Heavy traffic and vibration:** dumpers, coal trucks and machinery load the edges of roads and embankments every day. - **Long service life:** plant infrastructure is expected to work for decades with limited downtime for repairs. Protection works on a site like this have to drain freely, tolerate settlement and keep working after the ground moves. That is the brief double-twisted wire mesh was developed for. ## What double-twisted hexagonal wire mesh is Ocean Double Twisted Hexagonal Shaped Steel Wire Mesh is woven from galvanised steel wire. Pairs of wires are twisted together through three half-turns, and the twisted pairs are joined to form a hexagonal opening. The twist is what matters. If a wire is cut or damaged, the twist locks the mesh around the break, so it does not unravel the way a single-twist or chain-link mesh can. The hexagonal pattern also lets the mesh deform under load without tearing, so it follows settling ground and keeps holding its fill. In India, this product is covered by IS 16014, the BIS specification for mechanically woven, double-twisted hexagonal wire mesh gabions, revet mattresses and rockfall netting. ASTM A975 and EN 10223-3 cover it internationally. These standards set wire diameter, mesh size, coating mass and tensile requirements, which gives engineers a measurable basis for specification and acceptance. Ocean supplies this mesh to these standards, with wire diameter, coating and mesh dimensions checked against the specification before dispatch. ## Typical specification parameters The table below shows the parameters an engineer specifies for double-twisted mesh. Values are typical of IS 16014 practice; the exact figures for any project come from its design and the current edition of the standard. | Parameter | Typical values | | --- | --- | | Mesh type (D = distance between twists) | 6×8 (60 mm), 8×10 (80 mm), 10×12 (100 mm) | | Mesh wire diameter | 2.2 to 3.0 mm (2.7 mm common for 10×12) | | Selvedge (edge) wire diameter | 2.7 to 3.9 mm (3.4 mm common for 10×12) | | Lacing wire diameter | 2.2 mm | | Coating | Heavy zinc, zinc-aluminium (Zn-5%Al), or PVC over galvanised wire | | Governing standards | IS 16014, ASTM A975, EN 10223-3 | | Design guidance | IRC:SP:116 for gabion structures | Coating choice drives service life. Galvanised wire suits dry and freshwater sites with normal soils. Where the mesh will sit in acidic runoff, saline water or permanently wet ground, a PVC coating over the galvanising protects the zinc and extends life considerably. Coal handling areas can produce acidic drainage, so coating selection deserves attention at the design stage. ## Where the mesh works on a coal plant site Double-twisted mesh is a versatile material, and on a power and mining site it usually serves several purposes at once. **Gabion retaining walls.** Formed into boxes, laced and filled with hard stone, the mesh becomes a gravity wall. Gabion walls hold back fill along roads, coal yards and conveyor corridors. Because the stone fill is permeable, water drains straight through, so no hydrostatic pressure builds up behind the wall. **Slope and embankment protection.** Laid over a slope or formed into mattresses, the mesh armours exposed faces against rain wash and gully erosion. This matters for embankments and dumps where loose material would otherwise be carried into drains. See our [erosion control solutions](https://oceangeosynthetics.com/solution/erosion-control/) for related systems. **Drain and channel lining.** Storm water channels on a plant site carry heavy, fast flows during the monsoon. Gabion mattresses line the bed and sides, resisting scour while still letting water seep into and out of the ground. **Rockfall and debris control.** Hung as drapery over cut rock faces, the mesh guides loose stones down to a catch ditch rather than onto roads and work areas. Our [rockfall protection](https://oceangeosynthetics.com/products/rockfall-protection/) page covers this use in detail. ## Why double-twisted mesh over rigid construction Concrete and masonry walls are still common on industrial sites, but they have real limits on ground like Singrauli’s. | Factor | Double-twisted mesh gabions | Rigid concrete or masonry | | --- | --- | --- | | Response to settlement | Deforms and keeps working | Cracks and loses strength | | Drainage | Free-draining through stone fill | Needs weep holes and filter media | | Construction | No formwork or curing; hand-assembled | Formwork, curing time, skilled labour | | Materials | Local stone fill | Cement, steel and aggregate hauled in | | Repair | Damaged units can be patched or replaced | Usually needs breaking out and recasting | | Vegetation | Silt in voids allows plants to establish | Remains a hard, bare surface | Speed is the other factor. A plant cannot pause operations for long civil works, and the dry season is short. Gabions arrive folded flat, go together by hand and use local stone. Ocean has supplied double-twisted gabions for similar demanding work, including bank and scour protection at a [lock-cum-bridge in Malappuram, Kerala](https://oceangeosynthetics.com/double-twisted-gabions-at-a-lock-cum-bridge/) and slope stabilisation on a [highway corridor in Srinagar](https://oceangeosynthetics.com/mountain-engineering-in-srinagar-using-gabion-boxes/). Closer to the coalfields, our [rope gabions at Talcher, Odisha](https://oceangeosynthetics.com/ocean-rope-gabions-for-retaining-walls-in-talcher-odisha/) went into retaining walls and runoff control. This is where Ocean’s experience helps. Our team advises on mesh type, wire diameter and coating for each site’s soil and water conditions, so the material supplied matches the job rather than a generic catalogue entry. ## Supply and delivery The 140 pieces of Ocean Double Twisted Hexagonal Shaped Steel Wire Mesh were manufactured, inspected and dispatched to Singrauli for the plant’s civil works. The mesh is delivered folded and bundled, which keeps transport compact and handling simple on a busy site. Pre-dispatch checks on mesh of this kind cover: - Wire diameter for mesh, selvedge and lacing wire - Mesh opening dimensions and twist quality - Zinc coating mass and adhesion - Unit dimensions and, for boxes, diaphragm placement ## Installation good practice The performance of a gabion or mesh structure depends as much on construction as on the material. On sites like this, the following steps make the difference: 1. Level and compact the foundation, and remove soft pockets before placing the first course. 2. Place a non-woven [geotextile](https://oceangeosynthetics.com/products/geotextile-manufacturers/) filter behind any gabion that retains soil, so fines do not wash out through the stone. 3. Assemble each unit, then lace it to its neighbours with the specified tying wire so adjacent boxes act as one mass. 4. Fill with hard, durable stone larger than the mesh opening, hand-packing the exposed faces to reduce voids. 5. Fit internal connecting wires in taller units to stop the faces bulging. 6. Lace each course to the one below, stepping or battering the wall as the design requires. Most gabion failures trace back to undersized stone, slack lacing or a missing filter layer. ## Long-term performance Over time, silt settles into the voids and grass roots through the stone, binding the fill and blending the structure into the ground. Routine maintenance is light. A visual check after each monsoon for damaged wire, displaced stone or scour at the toe is usually enough. Any local damage can be repaired by lacing in a new panel, without disturbing the rest of the wall. ## Frequently asked questions ### What is double twisted hexagonal wire mesh? It is a steel wire mesh in which pairs of wires are twisted together through three half-turns to form hexagonal openings. If one wire breaks, the twist stops the mesh from unravelling, so it keeps its shape and strength. ### Which standard covers double twisted wire mesh in India? IS 16014 covers mechanically woven, double-twisted hexagonal wire mesh gabions, revet mattresses and rockfall netting. ASTM A975 and EN 10223-3 are the common international equivalents. ### Galvanised or PVC-coated mesh for a coal plant? Galvanised mesh suits dry ground and normal soils. Where the mesh sits in acidic runoff from coal handling areas, saline water or permanently wet ground, PVC coating over galvanised wire gives a much longer service life. ### Why use gabions instead of a concrete retaining wall? Gabions drain freely, tolerate settlement without cracking, need no formwork or curing, and use local stone. On disturbed ground around mines and plants, that flexibility is the main advantage. ## Ocean Non Wovens: geosynthetics for India’s infrastructure Ocean Non Wovens manufactures and supplies high-performance geosynthetics and wire mesh products for large-scale civil engineering across India.
