What 3G Shielding Specialties does

3G Shielding Specialties LP is a privately held, US-based manufacturer of EMI/RFI shielding and thermal management components, founded in 1994 and headquartered in St. Petersburg, Florida with a secondary office in Oceanside, California. The company sells board-level shields, enclosure-level conductive gaskets, microwave absorbers, and thermal interface materials under four product families (Board Level Shielding, Enclosure Shielding/Waveseal, Microwave Absorbers/Wavexorb, and Thermaworx). Differentiated offerings include proprietary MULTIZONE and Hybrid shield technologies, vulcanized conductive elastomers compliant with MIL-DTL-83528D, and integrated turn-key packages that combine metalwork, conductive elements, absorbers, and thermal transfer materials in a single design.

The company's go-to-market is application-engineering-led: prospective customers engage via website contact forms or sample kit requests, and 3G's application engineers function as an extension of the customer design team, producing detailed specifications and solid models with same-business-day engineering responses and 48-hour sample shipping. Pricing is quote-based, project-specific, and tied to multi-year contracts. 3G sells across defense/aerospace, telecommunications (including 5G base stations), medical electronics, industrial electronics, automotive/EV, and consumer electronics; ITAR registration (DoD No. M36737, CAGE 7PCU6), ISO 9001:2015 certification, and JOSCAR registration underpin defense supply chain access.

The business operates at a modest scale of 51-100 employees, produces millions of board-level shields per year, and is self-funded with no disclosed institutional investors, parent company, or M&A history. Commercial activity through 2025-2026 includes a December 2025 next-generation EMI gasket launch and confirmed exhibition at IMS Boston 2026, indicating continued organic reinvestment rather than capital-driven expansion.
