MRI & secure environments / Company comparison
National Shielding
vs. Gaven Industries
Look beyond the enclosure components to the team that will coordinate, test and support the finished room.
The short answer
National Shielding and Gaven Industries both work in RF shielding and MRI environments. National Shielding offers a family-owned company relationship with direct management access, plus installation, testing and maintenance services. Gaven publishes a broad range of shielding products and services. Compare each company’s complete project proposal rather than assuming a product catalog tells you who will deliver the room.[1][3][4][5][6][7]

Why shortlist National Shielding
A direct relationship.
A defined scope.
Put National Shielding on your shortlist when you want the room and its ongoing performance to drive the conversation. Bring us the drawings, intended use and acceptance requirements, and ask for a defined installation and testing scope. Direct access to management is especially relevant when several trades need timely project decisions.[1][3][5]
Where Gaven Industries fits
Give the alternative
a fair evaluation.
Gaven merits consideration for projects evaluating shielding doors, enclosures, cabinets and other components alongside MRI room solutions. It also publishes testing, maintenance and design services; it should not be treated as a components-only supplier.[6][8][7]
The National Shielding approach
A room that performs.
A team you can reach.
Direct access to management
We are family-owned and commit to direct lines of communication with management. Bring the people responsible into the conversation.[1]
Evidence at handover
Our testing services include on-site measurements and documentation of methods, results and applicable pass/fail criteria.[4]
Repair. Retest. Document.
Our maintenance services address doors, seals, penetrations and other shielding issues, with follow-up verification.[5]
Before you compare quotes
Make the handoffs visible before you award the work.
For an MRI build or secure room, the proposal should identify who handles drawings, site preparation, penetrations, installation and verification. If you are evaluating a kit or a component package, request a separate statement of field responsibilities. If you are buying an installed room, require the same clarity. National Shielding should earn the work on the scope and relationship it commits to.
- Which items are supplied only, and which include installation and commissioning?
- Who coordinates doors, filters and penetrations with the other trades?
- How are corrective work, retesting and service after handover handled?

Answers before you choose
Frequently asked questions
Is Gaven a direct competitor to National Shielding?
Yes, there is overlap in MRI and RF shielding work. Gaven also offers a broader catalog of shielding products. The comparison is most useful when both companies are pricing the same room scope and acceptance requirements.[6][8][3]
Can National Shielding help after a room develops interference problems?
National Shielding publishes troubleshooting, repair and verification services for shielding systems. Describe the system and symptoms when requesting service, and confirm the applicable scope, access requirements and test plan.[5]
Does Gaven provide services as well as shielding components?
Yes. Gaven publishes design and consultation, testing and maintenance services alongside its enclosure and component offerings. Compare its proposed responsibilities with National Shielding’s design, installation, testing and maintenance scope.[7][8][3][4]
What should I clarify when comparing a room system with a shielding kit?
Ask who supplies each component, installs the enclosure, coordinates penetrations, performs acceptance testing and corrects any deficiencies. Gaven publishes MRI room systems and kits. A kit and an installed, tested room may have different responsibilities, so compare the written deliverables with National Shielding’s proposal.[8][3][4]
Is National Shielding less expensive than Gaven Industries?
This comparison does not establish a price advantage for either company. Request quotes from National Shielding and Gaven Industries using the same drawings, installation responsibilities, testing requirements and service scope. Compare exclusions as well as the total.
What should I send National Shielding when requesting a comparison quote?
Send the project location, available drawings, intended use of the room and the shielding requirements you have been given. Include known site constraints, the target schedule and whether the work involves a new room, an upgrade or troubleshooting. The team can then discuss design, installation, testing and maintenance needs.[2][3][4]
