Question 1

What is the difference between electro-galvanized and hot-dipped galvanized gabion mesh?

Accepted Answer

Electro-galvanized (cold galvanized) has a thinner zinc coating and is suitable for indoor or dry environments. Hot-dipped galvanized has a much thicker coating, offering superior rust resistance, making it ideal for outdoor projects, rivers, and coastal areas.

Question 2

Do you offer PVC coated or Galfan wire options?

Accepted Answer

Yes. We provide PVC coated wire for extra protection against corrosion and abrasion, available in various colors (green, grey, black). We also supply Galfan wire (Zn-5% Al-MM), which offers 2-3 times better corrosion resistance than standard galvanized wire.

Question 3

What are the standard sizes for gabion boxes?

Accepted Answer

The most common standard sizes are 2x1x1m, 3x1x1m, and 4x1x1m. However, we can customize any size according to your project drawings, including length, width, height, and mesh opening size (e.g., 60x80mm, 80x100mm).

Question 4

What wire diameter do you use for the mesh and the selvedge?

Accepted Answer

Typically, the mesh wire diameter ranges from 2.0mm to 4.0mm. The selvedge (edge) wire is usually thicker (2.7mm-4.0mm) to ensure structural strength. We strictly follow ASTM or ISO standards based on your requirements.

Question 5

Why is the "double twist" design important?

Accepted Answer

The double twist hexagonal mesh design ensures that if one wire is cut or broken, the mesh will not unravel or fall apart. This provides high safety and structural integrity for retaining walls and flood control projects.

Question 6

Do the gabion boxes come with diaphragms?

Accepted Answer

Yes, for boxes longer than 1 meter (e.g., 2m, 3m, 4m lengths), we install internal diaphragms (stiffeners) at 1-meter intervals. This prevents the box from bulging when filled with stones and maintains the shape.

Question 7

How are the gabion boxes packed for shipping?

Accepted Answer

They are packed flat in bundles to save shipping space and costs. Typically, secured with steel straps. A 20ft container can usually hold a large quantity depending on the size.

Question 8

What kind of stones should be used to fill the gabions?

Accepted Answer

You should use hard, durable stones that are larger than the mesh opening (usually 1.5 times the mesh size) to prevent them from falling out. The stones should be resistant to weathering and water erosion.

Question 9

Can gabion nets be used for decorative purposes?

Accepted Answer

Absolutely. Besides civil engineering, they are popular in landscape architecture for garden walls, privacy screens, and furniture. Using colored stones or glass inside PVC-coated cages creates a modern aesthetic look.

Question 10

Do you provide samples for testing?

Accepted Answer

Yes, we can provide free small samples of the wire mesh for you to check the quality, zinc coating, and flexibility. You usually just need to cover the courier cost.

Question 11

Can you manufacture gabion boxes in custom sizes different from the standard?

Accepted Answer

Yes, we specialize in customization. While we have standard molds (e.g., 2x1x1m, 3x1x1m), we can manufacture gabions in any length, width, and height according to your engineering drawings. We can also adjust the wire diameter (2.0mm - 4.0mm) and mesh opening size (60x80mm, 80x100mm, etc.) to meet specific project requirements.

Question 12

Are gabion walls environmentally friendly compared to concrete walls?

Accepted Answer

Absolutely. Gabions are a "green" solution. They are permeable, allowing water to flow through freely, which reduces hydrostatic pressure and prevents water buildup. Over time, soil and vegetation can grow into the stone voids, integrating the structure naturally into the landscape and providing habitats for small wildlife.

Question 13

Do your products meet international standards like ASTM or ISO?

Accepted Answer

Yes, our manufacturing process strictly adheres to international standards. We can provide test reports for tensile strength, zinc coating weight, and mesh torque according to ASTM A975 or ISO 10223 standards to ensure the quality meets your project specifications.

Question 14

What is your Minimum Order Quantity (MOQ) for a trial order?

Accepted Answer

We understand you may need to test our quality first. Our standard MOQ is usually one 20ft container (mixed sizes are acceptable). However, for trial orders, we can accept smaller quantities (e.g., 200 sets) to support your initial project needs, though the unit price may vary slightly due to fixed production setup costs.

Question 15

What is your monthly production capacity, and can you handle urgent large-scale projects?

Accepted Answer

We operate multiple automated weaving machines with a monthly capacity exceeding 500,000 square meters. For urgent large-scale infrastructure projects (like flood control or highway construction), we can prioritize your order in the production schedule to ensure on-time delivery without compromising quality.
