Concertina Razor Barbed Tape Manufacturer & Supplier
Manufactured in Howrah • Securing Defense, Industrial & High-Risk Perimeters Across India
SAI INDUSTRIES produces ultimate-tier Razor Barbed Tape & Concertina Coils engineered to deliver extreme psychological and physical intrusion deterrence. Manufactured at our state-of-the-art facility in Howrah, West Bengal, our razor wire solutions combine high-tensile spring steel wire cores enclosed by razor-sharp, zinc-coated steel blades designed to prevent scaling, cutting, or breaching.
From heavy-duty BTO-22 and CBT-65 blade profiles for military installations to single-coil and cross-concertina configurations for commercial boundaries, each roll is cold-clamped to maintain rigid structural coil tension. We deliver customized loop diameters, coil lengths, and heavy galvanized coatings to meet strict defense and infrastructure security standards across Kolkata, West Bengal, and nationwide networks.
Certified high-tensile core • High GSM zinc blade coverage • Direct factory dispatch from Howrah, WB.

Core Engineering Advantages
IMPASSABLE INTRUSION BARRIER
Razor-sharp teeth combined with multi-directional concertina loops physically entrap intruders attempting to breach or climb.
CUT-RESISTANT HIGH-TENSILE CORE
The inner spring steel core wire resists hand tools, wire cutters, and heavy mechanical shear attempts.
CORROSION & WEATHER PROOF
Heavy-zinc hot-dip galvanizing protects razor edges and inner core wire against atmospheric rust and extreme outdoor wear.
FLEXIBLE OVERLAY INTEGRATION
Mounts seamlessly on Y-arm brackets, security wall toppings, chain link fences, or directly along ground perimeters.
