Dragon’s teeth (ПЗ-1): how a concrete pyramid stops vehicles
The ПЗ-1 barrier pyramid is a simple-looking concrete tetrahedron that forms an anti-tank line. How it works and how many you need.
«Dragon’s teeth» are ПЗ-1 barrier pyramids — concrete tetrahedrons placed in rows to stop or slow armoured vehicles. Effectiveness comes not from a clever shape but from mass, strength and correct placement.
Why reinforced concrete
- Mass and strength. Heavy reinforced concrete withstands impact and does not shift.
- Resistance over time. The product is not afraid of weather and lasts for years.
- Readiness. The pyramid arrives ready — no on-site work except placement.
- Scale. Thousands of units in a short time — enough to cover a whole line.
A line, not single elements
Anti-tank effectiveness comes from systems of several rows of pyramids with calculated spacing. We produce ПЗ-1 in large batches at two sites, so we can quickly cover the need of an entire line.
We will calculate the quantity for your line length — send the parameters.
