Rockfall Netting Manufacturing Process

Rockfall netting buyers often see finished rolls first, but the manufacturing process is more useful for checking whether a supplier understands the specification. Double twisted rockfall netting depends on wire preparation, mesh forming, edge processing, roll checking and packing. If one step is unclear, the final order may still look similar in a photo but differ in wire diameter, mesh opening or surface treatment.

This article explains the process in procurement language. It does not treat workshop photos as project cases. They are production records that help buyers understand how the product is made and what should be checked before shipment.

1. Wire and Coating Preparation

Production starts with wire that matches the required coating system. A rockfall netting order may use hot dipped galvanized wire, Galfan wire, PVC coated galvanized wire or PVC coated Galfan wire. The buyer should not confirm the order only by product name.

Before production, the supplier should know:

• Mesh opening

• Mesh wire diameter

• Selvedge wire diameter

• Roll width and roll length

• Surface treatment

• Zinc coating, Galfan alloy or PVC coating requirement

• Quantity and packing method

For PVC coated rockfall netting, both the inner wire diameter and the coated outside diameter should be stated. A 2.7 mm inner wire and a 3.7 mm coated wire are not the same measurement, and both may be needed for inspection.

2. Mesh Forming

Rockfall netting is generally made as double twisted hexagonal mesh. During mesh forming, wires are twisted into continuous hexagonal openings and produced into roll form. The mesh opening, wire diameter and coating must stay consistent with the confirmed order.

For buyers, mesh forming matters because it affects whether the supplied product matches the project specification. A quotation that says only "rockfall netting" is incomplete. The rockfall netting specifications should be used to confirm the measurable details before production.

3. Traction, Rolling and Roll Size Control

After mesh forming, the netting is pulled, collected and rolled according to the required roll size. Common roll sizes may include 2x25 m, 2x50 m, 3x25 m, 3x50 m, 4x25 m or 4x50 m, depending on order requirement.

Roll size is not only a packing detail. It affects:

• Quantity calculation

• Loading arrangement

• Installation handling

• Lacing wire requirement

• Export packing method

Buyers who need special roll dimensions should confirm them before production instead of changing them after the rolls are finished.

4. Selvedge Processing

Selvedge processing refers to the edge treatment of the roll. The selvedge wire is usually heavier than the mesh wire and should be confirmed as a separate specification item.

Selvedge details are important because they are connected with site handling and roll connection. If lacing wire is required, the buyer should also confirm the lacing wire for rockfall netting requirement, including diameter, coating and packing.

5. Finished Roll Checking

Finished roll checking should focus on measurable items rather than only appearance. Useful checks may include:

• Mesh wire diameter

• Selvedge wire diameter

• Mesh opening

• Roll width and roll length

• Surface treatment

• Zinc coating or coated wire diameter, depending on product type

• Finished roll condition

• Packing preparation

If the order requires inspection support, buyers can ask for rockfall netting quality checks such as wire diameter measurement, mesh opening measurement, zinc coating testing, tensile or elongation records, or certificate information where applicable.

6. Packing and Export Preparation

Packing is the last step before shipment, but it should be discussed early. Roll size, bundle method, lacing wire, documents and loading arrangement can all affect export preparation.

Shipment photos may show finished rolls, packing condition and loading preparation. They are useful as order communication records, but they should not be described as completed engineering cases unless the project information is verified and approved for public use.

ANPING YUELIAN WIRE MESH CO., LTD. is based in Anping, Hebei, China, and the public site presents rockfall netting production, quality and quotation information for overseas buyers. To prepare an order review, send mesh opening, wire diameter, roll size, coating, quantity, packing notes and destination details through the request rockfall netting quotation page.

Buyer Summary

The rockfall netting manufacturing process runs from wire preparation to mesh forming, rolling, selvedge processing, finished roll checking and packing. Buyers do not need to inspect every factory step in person, but they should confirm the measurable specification before production and request relevant inspection records when the order requires them.
