358 mesh fencing, also referred to as "Prison Mesh," provides exceptional value in terms of performance, durability, and appearance. The name "358" originates from its dimensions—3" x 0.5" x 8 gauge—which convert to approximately 76.2mm x 12.7mm x 4mm in metric units. This fencing is specifically engineered for high-security environments and is finished with a heavy zinc coating or RAL powder coating, combined with a robust steel framework.
358 mesh fencing, often called "Prison Mesh," is a high-security fence system designed for areas requiring strict security. The name "358" comes from its panel dimensions: 3 inches by 0.5 inches with 8-gauge wire, which translates to 76.2mm x 12.7mm in metric. This type of fencing is made from low-carbon steel wire and features small, tightly spaced mesh apertures that prevent climbing or cutting.
Due to its strength and durability, 358 mesh fencing is commonly used in high-security locations like prisons, military bases, airports, and power plants. It is often coated with a protective zinc layer or RAL powder coating to increase resistance to corrosion and weathering. Its design combines security, performance, and longevity.
