Q1:What is the difference between welded mesh gabions and twisted (woven) gabions?
A:Welded Gabions: Made from steel wires welded at every intersection, forming a rigid and stable structure. They offer a neat, square appearance and are stronger for retaining walls and architectural facades.
Twisted (Woven) Gabions: Made from wires twisted together, allowing more flexibility. They are better suited for uneven ground or applications where slight movement is expected (like riverbanks).
Q2:What wire material and coating are used to ensure long-term corrosion resistance?
We use high-quality low-carbon steel wire. The primary corrosion protection is Hot-Dipped Galvanized coating (typically over 250g/m²). For extreme environments (coastal, chemical, or highly polluted areas), we offer an additional PVC Coating or use Galfan (zinc-aluminum alloy) which provides 2-3 times better corrosion resistance than traditional galvanized.
Q3:What are the standard panel sizes and mesh openings?
A:Common welded gabion sizes (Length x Width x Height) include 2m x 1m x 1m, 1.5m x 1m x 1m, and 2m x 1m x 0.5m. Standard mesh openings are typically 50mm x 50mm, 75mm x 75mm, or 100mm x 100mm. The wire diameter usually ranges from 2.7mm to 4.0mm, depending on the mesh size and application.
Q4: How are the panels connected to form a box?
A: The gabion boxes come as flat panels for economical shipping. On-site, you connect them using heavier gauge connecting wires or spiral binders (lacing wire) provided with the order. These are inserted through the matching edges and twisted to form a secure, continuous box. Internal diaphragms (partitions) are also supplied to maintain the box shape when filled.
Q5:How is it packaged for shipping to prevent damage?
AThe flat panels are bundled together, often on pallets, and tightly secured with steel strapping. They are then wrapped in waterproof materials (like PP woven fabric) to protect the galvanized coating from moisture and damage during sea freight. This compact packaging also minimizes shipping costs.
