Before ordering rockfall netting for a project installation, the user should not confirm price only. The supply scope, mesh opening, wire diameter, roll size, surface treatment, lacing wire, packing and delivery information should be clear first.
The rockfall netting discussed here is double twisted hexagonal steel wire mesh supplied in rolls. It can be supplied as material for slope rockfall protection, but it is not a complete active protection system, passive rockfall barrier, anchor system or steel rope netting system. Installation method, anchor layout and site safety should be confirmed by the project side or installation team according to actual site conditions.
1. Confirm the Supply Scope First
Many projects use the term "rockfall netting," but the actual purchase scope may be different. Some users only need double twisted hexagonal rockfall netting rolls. Other projects may also involve anchors, steel ropes, support ropes, plates, posts or other system components.
Before ordering, confirm:
- Whether this order is only for rockfall netting rolls
- Whether lacing wire or connection wire is needed
- Whether anchors, steel ropes or plates are supplied by another party
- Whether the project document has already defined the material scope
- Whether the order is material supply only, without site installation service
This step is important. Otherwise, mesh roll material may be misunderstood as a complete slope protection system, and the later quotation and delivery scope will not be clear.
If the user is not sure about the product scope, see what rockfall netting is.
2. Confirm Mesh Opening, Wire Diameter and Selvedge Wire
The core specifications of rockfall netting start with mesh opening and wire diameter. Saying only "we need rockfall netting" is not enough. The factory needs the mesh opening, main wire diameter and selvedge wire requirement.
Common confirmation items include:
| Item | What to confirm |
|---|---|
| Mesh opening | 60x80 mm, 80x100 mm, 100x120 mm or project requirement. |
| Mesh wire diameter | Main wire diameter used in the mesh body. |
| Selvedge wire diameter | Wire specification along the roll edge. |
| Mesh structure | Double twisted hexagonal mesh. |
| Quantity | Square meters, roll quantity or project quantity. |
These parameters affect the actual product, weight, packing, production and later site preparation. Mesh opening and wire diameter should be read together. The same mesh opening with a different wire diameter means a different product.
The rockfall netting specification table can be used as a basic reference.
3. Confirm Roll Width and Roll Length
Rockfall netting is usually supplied in rolls, so roll width and roll length should be confirmed before ordering. Roll size affects packing, container loading, handling, site distribution and later unrolling preparation.
The user should confirm:
- Width of each roll
- Length of each roll
- Total square meters
- Total roll quantity
- Whether different specifications need separate labels
- Whether the site has limits for single-roll weight or size
If the site road is narrow, the slope is divided into clear work areas or handling conditions are limited, roll size should not be decided at the last moment. Clear roll width and roll length make later receiving and material distribution easier.

4. Confirm Surface Treatment
Rockfall netting is exposed outdoors for a long time, so surface treatment should not be chosen only by product photos or price. Common options include hot dipped galvanized, Galfan, PVC coated galvanized and PVC coated Galfan.
When confirming surface treatment, consider:
- Project environment
- Whether the site is humid, coastal, mine-related or exposed to long-term rain wash
- Whether there is a corrosion-resistance requirement
- Whether there is a color requirement
- Whether the project document has a specified coating
- Budget and service-life reference
Common directions can be understood this way:
| Use environment | Surface treatment direction |
|---|---|
| General outdoor slope | Hot dipped galvanized. |
| Higher corrosion resistance than standard galvanized wire is needed | Galfan. |
| Humid, coastal, rain-washed or color-required project | PVC coated galvanized or PVC coated Galfan. |
Coating selection should not be simplified into saying that one option is always the best, and it should not be used to promise a fixed service life. Later condition depends on environment, installation, maintenance and exposure conditions.
For selection logic, see how to choose rockfall netting.
5. Confirm Whether Lacing Wire Is Needed
If later connection, joining or fixing needs lacing wire, it should be confirmed before ordering. Lacing wire is not the main product, but it is a common support detail in a rockfall netting order.
Confirm:
- Whether lacing wire is needed
- Lacing wire diameter
- Whether the surface treatment should match the main netting
- Quantity or weight
- Whether it should be packed with the netting rolls
- Whether separate labels are needed
The focus here is order support, not promoting lacing wire as an independent main product.
6. Confirm Packing, Labels and Delivery Information
Rockfall netting is roll material, so packing and labels affect receiving, sorting and later site preparation. If one shipment includes different roll widths, wire diameters or coating types, labels and packing records become more useful.
Before ordering, confirm:
| Item | Notes |
|---|---|
| Packing method | Standard bundling, pallet or other requirements. |
| Roll labels | Whether specification, roll count and size should be marked. |
| Separate packing by specification | Useful when different wire diameters, roll widths or coatings are shipped together. |
| Destination country or port | Needed for transport and delivery discussion. |
| Trade term | FOB, CFR, CIF or another agreed term. |
| Document requirement | Packing list, invoice, certificate or other documents. |
Packing photos, container loading photos and delivery photos belong to supply records, loading records or shipment records. They should not be described as completed engineering cases.
7. Confirm Whether Pre-Shipment Product Photos or Documents Are Needed
If the user needs to confirm product condition before shipment, this should be stated before ordering. The factory can then arrange photos or documents in advance.
Common items include:
- Finished roll photos
- Mesh opening measurement photos
- Mesh wire diameter measurement photos
- Selvedge wire measurement photos
- Packing photos
- Label photos
- Container loading photos
- Test records or certificate information required by the order
These records are used to confirm supply status. They are not engineering acceptance and cannot replace site installation checking.
8. Summary
Before ordering rockfall netting for installation, the user should first confirm the supply scope, then confirm mesh opening, wire diameter, selvedge wire, roll width, roll length, surface treatment, lacing wire, packing, labels and delivery records.
These details belong to material supply and installation preparation. They are not construction methods or complete engineering design. Yuelian can support specification, support material, packing and delivery-record confirmation for double twisted hexagonal rockfall netting rolls. Site installation method, anchor layout and safety judgment should remain with the project side or installation team.
