Professional FAQ: Technical Terms & Buying Advice

1. What is the difference between BTO and CBT blade profiles?
BTO (Barbed Tape Obstacle) and CBT (Concertina Barbed Tape) refer to the shape and size of the razor profile. CBT blades, such as CBT-65, are larger and typically used for critical infrastructure, while BTO (e.g. BTO-22) is common for general perimeters. BTO is easier to produce and less aggressive, while CBT is heavier duty.
2. Which materials are recommended for extreme corrosion environments?
For high-salinity or petrochemical zones, SS304/316 stainless steel or double-coated hot-dip galvanized wires (per ISO 1461 and ISO 9223) offer maximum corrosion resistance and longevity.
3. What industry standards apply to Double Loop Concertina Razor Barbed Wire Coil?
Key standards include ISO 9001:2015 (quality), ISO 1461 (zinc coatings), ASTM A123/A370 (mechanical/tensile tests), and EN 10223-7 (razor wire geometries).
4. How is installation quality ensured?
Professional installation follows ICC/ANSI fence codes with pre-site ground analysis, coil spacing templates, and tension-force testing. Each batch includes an ISO/CE-certified quality test report.
5. What warranty and support are provided?
XZMetal supplies Double Loop Concertina Razor Barbed Wire Coil with a 2-year product guarantee, on-site technical support, and lifetime project traceability.
6. Is it possible to order custom coil lengths or colors?
Yes. Coils from 450mm up to 1200mm with color-matched or anti-UV PVC coatings are available. Installation brackets and security seals can also be customized.
7. How quickly is delivery?
For most standard configurations: 10-15 working days after order. Large projects are supported with partial delivery, phased according to site needs.
