Hail Protection Covers
Hail damage causes $10-15 billion in U.S. losses every year, and no market feels it like aviation. In 2013, a single hailstorm at Kandahar Airfield damaged more than 80 helicopters and aircraft parked in the open, proving that even hardened military assets are exposed on the flight line. Transhield Hail Protection Covers give commercial and military aviation operators, along with the broader military community, a practical defense against hail damage. Each cover is custom fit to your aircraft or equipment and engineered for hail alley, forward operating locations, and other regions where hail and severe weather are a regular threat.
Tested Hail Impact Protection
Transhield HPC material is tested to a modified ASTM F320 standard, shielding metal from 1-inch hail at 45 mph. In testing, the fabric absorbed and dispersed impact energy, leaving covered aircraft aluminum with no visible dents:
Mission Readiness
Aircraft that avoid hail damage stay off the repair line and on the schedule, protecting mission readiness for military units and dispatch reliability and continued operations for commercial operators.
Saves Time
A faster application process means less labor spent covering equipment and personal safety when a tornado warning or severe thunderstorm hits the forecast.
Customizable Features
Vents, zipper doors, hook and loop closures, straps, and labeling can be built into the design to match how your team handles and accesses each unit.
Custom-Design & Fit
Our Data Acquisition and Design teams build each cover around your product’s exact shape and dimensions, reinforcing wear points for repeated use. There are no limits on shape or size.

| Puncture (lbs) | 340+, no puncture observed | ASTM D4833 |
Frequently Asked Questions
Yes. In controlled testing, unprotected aluminum panels showed severe denting, while panels under a Transhield cover showed no visible dents from 1-inch hail at 45 mph. The fabric absorbs impact energy before it reaches the surface, a proven form of hail damage prevention.
Our engineering team ran controlled impact testing using a modified version of ASTM F320, with 1-inch and 2-inch hail at 45 to 72 mph against aircraft aluminum. The material also passed ASTM D4833 puncture testing at over 340 lbs of applied force.
Transhield HPC is built for military aviation, commercial aviation, and ground forces protecting aircraft, rotorcraft, and equipment staged in the open. The same covers also serve government fleets, industrial equipment, and other vehicle and machinery applications.
A generic hail blanket or hail protection tarp is a one-size sheet that needs constant adjusting and frequent replacement. A Transhield HPC is engineered to your product’s exact dimensions and stays put through strong winds.
A hail storm can ground aircraft for weeks, driving hail damage repair bills, insurance claims, and lost availability. For military units, that means degraded readiness and diverted maintenance manpower. Preventing the damage costs far less than repairing it after the worst hailstorms.
30+ Years of Protection You Can Count On
Since 1994, Transhield has designed custom covers that keep valuable equipment protected through shipping, storage, and severe weather. A 97.4% customer retention rate and an ISO 9001:2015 certified quality management system reflect how seriously we take that work. When you partner with Transhield, our design and engineering teams study your aircraft, equipment, and storage conditions before building a cover around them. The result is hail protection made for your operation rather than a generic solution pulled off a shelf.
