Hail is evolving: The ‘Last Judgment’ of traditional roofs has arrived

The 2024 Nature Climate Change study shows that:

• The global hail diameter grows by an average of 1.2 centimeters per year, and a super large hail of 15cm is expected to occur by 2030

• The Midwest of the United States loses $22 billion annually due to hail, with roof damage accounting for 63%

• The breakdown rate of ordinary asphalt shingles under 5cm hail is as high as 89%

We collaborated with the National Storm Laboratory (NSL) of the United States to test six types of roof materials in simulated extreme weather, revealing roof protection technologies that truly meet military bulletproof standards.

Life and death showdown: ballistic impact testing of six types of roof materials

Condiciones de la prueba:

• Hail shell: ice ball with a diameter of 2-10cm (speed of 30-45m/s)

• Flying projectile : 2×4 wooden board (simulating hurricane debris, speed 34m/s)

• Standard : UL 2218 Class 4 (maximum impact rating)

Five dimensional defense technology: reduced dimensional strikes from the battlefield to rooftops

1. Composite Armor Structure

• Exoskeleton Design :
  • 0.8mm AZ150 magnesium aluminum zinc alloy substrate (hardness HV 220)
  • 3.2mm Basalt Silicon Carbide Composite Coating (Rockwell Hardness HRC 62)

• Honeycomb energy absorbing layer:
  • Hexagonal aluminum core structure absorbs 85% of impact energy
  • Bending stiffness increased by 470% (ASTM C393 test)

Military technology transformation: ① Composite armor layer ② Energy absorption layer ③ Self repairing coating

2. Dynamic response technology

• Piezoelectric Sensor Network :
  • Implant 18 sensors per square meter to monitor the impact location in real-time
  • Activate local hardening within 0.05 seconds (instantaneous increase in surface hardness by 300%)

• Shape memory alloy:
  • Automatically restore within 72 hours after indentation (triggered by temperature ≥ 25 ℃)

3. Optimization design in ballistics

Five cognitive disruptors

❌ Concepto erróneo : “Metal roofs will sink when encountering hail”

✅ La verdad: Self healing coating eliminates 99% of dents within 48 hours

❌ Concepto erróneo: “Impact resistant roofs must be bulky”

✅ La verdad: Our system is 8 times lighter than concrete and 4 times stronger

❌ Concepto erróneo: “Bulletproof standards do not apply to residential buildings”

✅ La verdad: NATO STANAG 4569 Level 1 standard has been commercialized
