MicroGrid® Technology

MicroGrid® precision expanded material foils from Dexmet represent the industry standard for lightning strike protection in composite aircraft structures. As the exclusive expanded metal supplier for Airbus and Boeing, the principal supplier to Embraer, and the preferred vendor for the majority of aircraft manufacturers globally, Dexmet has established unparalleled market leadership.

Aircraft manufacturers are increasingly recognizing the superior benefits of Dexmet's advanced expanded materials compared to traditional woven wire technology. MicroGrid's single-unit structure offers significant advantages over woven materials, as it eliminates the risk of unraveling or loose strands that can create complications during pre-preg material processing or dry lay-up procedures. The homogeneous design ensures consistent conductivity between strands when forming the material into various configurations for end products.

MicroGrid's most significant advantage lies in Dexmet's ability to maintain precise manufacturing control to meet specific weight, open area, and conductivity requirements. This capability enables engineers to optimize material selection according to specific strike zones on aircraft, thereby minimizing overall weight while maintaining performance standards. Our standard materials are engineered to withstand Zone 1A strikes of up to 200,000 amperes.

Common MicroGrid® Materials

The following specifications represent our most frequently produced materials for lightning strike protection in composite aircraft structures across Zones 1, 2, and 3. For applications over rivet lines, lightning strike testing has demonstrated that materials with weights exceeding 400 gsm provide superior spark dissipation from embedded rivets. In wind energy applications, heavier configurations offer enhanced durability for repeated strike scenarios.

For specialized requirements involving heavier materials, alternative alloys or metals, varying thicknesses, and different pattern sizes, we recommend consulting with our sales and engineering professionals to determine the optimal characteristics for your specific application requirements.
