Product Introduction
Zhongman concertina razor wire is an aggressive coiled barrier formed from sharpened steel blades crimped onto a high-tensile core wire. Supplied as spiral coils or as concertina cross-type (CBT) where adjacent loops are clipped together, it expands accordion-style along a boundary to create a dense, three-dimensional obstacle that is extremely difficult to cross, cut, or climb. The razor barbs, pressed from galvanized or stainless sheet, deliver both physical penetration and psychological deterrence. Lightweight and rapid to deploy, concertina wire is the go-to solution for securing perimeters quickly, whether laid on the ground, mounted on walls and fences, or stacked in pyramid formations for maximum barrier depth and breach delay.
Key Features & Advantages
Concertina razor wire combines low cost with high deterrence. The CBT clip-bound coils spring open into a stable, self-supporting entanglement that resists being pushed aside, unlike loose spiral coils. Sharp BTO-22 and CBT-65 blades on a 2.5mm spring-steel core penetrate clothing and equipment, slowing and injuring intruders while signaling a hardened boundary. Hot-dip galvanizing gives long outdoor corrosion resistance; 304 stainless serves coastal and marine sites. The wire installs fast with minimal labor and can be added atop existing walls and fences to upgrade security instantly. Stackable pyramid configurations create wide, deep barriers, and the open coil structure preserves CCTV sightlines while presenting a clearly hostile obstacle.
Specifications & Options
Zhongman offers concertina razor wire with BTO-22, BTO-30, or CBT-65 blade profiles crimped to a 2.5mm spring-steel or 304 stainless core. Coil diameters of 450, 500, 700, and 960mm are available, with 33 to 56 loops per coil depending on stretch length. Choose spiral type for economical single-coil runs or clipped concertina (CBT) for a denser, more stable entanglement. Coatings are hot-dip galvanized (Z-class) for general use or solid 304 stainless for corrosive environments. Options include flat-wrap razor coil, mobile rapid-deployment frames, anchor clips and brackets for wall and fence mounting, and pyramid kits combining multiple coils for maximum barrier width and crossing difficulty.
Applications & Industries
Concertina razor wire secures the world's most sensitive perimeters. Correctional facilities and detention centers use it on wall and fence tops and in sterile zones. Military bases, defense installations, and border-control lines rely on rapid-deploy concertina for forward security. Critical infrastructure such as power stations, substations, oil and gas terminals, airports, and ports uses it to harden boundaries against intrusion. Industrial and commercial sites add it atop existing fencing to deter theft and vandalism. Temporary applications include event security, riot control lines, and emergency cordons where fast, formidable barriers are needed. Wherever maximum deterrence is required at minimal cost, concertina razor wire is the standard choice.
