FAQ

358G Anti-Climb Security Fence — Frequently Asked Questions

What does “358” mean and why is this fence so secure?
The name 358 comes from the mesh aperture: 3 inches × 0.5 inches with 8-gauge wire (roughly 76.2 × 12.7 mm). These small openings leave virtually no finger or toe holds for climbing and are extremely difficult to cut, giving the 358G outstanding anti-climb, anti-cut, and anti-disassembly performance. Paired with reinforced cold-formed I-shaped posts and a seamless design with no leverage points, it is the top high-security choice in our welded mesh range.
What are the mesh and post specifications of the 358G fence?
The 358 mesh is available in heights of 1500, 2000, 2500 and 3000 mm and widths of 2000/2500 mm, with wire diameter Ø4.0/Ø4.5 mm, vertical wire spacing 76.5/100 mm and horizontal wire spacing 12.5 mm, made from Q195 steel. The reinforced I-shaped posts measure 54.4×100 mm with 1.5/2.0 mm wall thickness, in heights from 1000 to 3000 mm, connected to the mesh with dedicated interlocks and anti-theft bolts.
What is the surface treatment and zinc coating?
The 358G fence uses a dual anti-corrosion process: the base material is hot-dip galvanized with a zinc coating of 80–120 g/m², then finished with an electrostatic polyester powder coating of over 100 microns (100–120 μm). With 200+ RAL color options available, this combination ensures long-lasting durability and corrosion resistance, even in demanding high-security and outdoor environments.
Is there a minimum order quantity MOQ?
We have no fixed minimum order quantity. Whether you need a trial order, a single project’s worth, or large-volume container shipments, we’re happy to support orders of all sizes, including smaller orders for new buyers and distributors.
What is the lead time and how do you pack for export?
Standard lead time is around 30 days, depending on order quantity and customization. All products are packed for export with protective packaging suitable for long-distance ocean freight, helping them arrive in good condition. We support FOB and CIF terms.
Which applications is the 358G fence best suited for?
The 358G anti-climb fence is purpose-built for high-security perimeters: prisons and correctional facilities, military bases, airports, substations and utilities, data centers, borders, and other critical infrastructure. Its anti-cut, anti-climb mesh makes it the right choice wherever maximum security is the priority.
What information should I provide to get an accurate quotation?
To prepare an accurate quotation, please provide the fence height, total length, wire diameter, mesh size, post type, color, quantity, delivery destination, and any project drawings if available.
