RF Steel Door & Frame Assemblies
General Description:
AMBICO radio frequency (RF) doors and frames are specialized products that minimize the transmission of electromagnetic energy that is transmitted across an opening. RF doors and frame assemblies offer reliable protection against electromagnetic interference in environments that contain sensitive equipment or confidential information. RF applications include government facilities, healthcare institutions, research laboratories, data centers, and industrial settings
Product Overview
| Design | Flush, single-panel steel door & frame assemblies independently tested to IEEE 299 for either 60 or 70dB attenuation across electric, planewave & microwave frequencies. |
| Configuration Options | 60dB assembly now offered in paired configuration incorporating an industry-first mullion-free design that uses an astragal instead of a removable or fixed mullion. 70dB assembly requires fixed mullion if paired. |
| RF & Acoustic Ratings | Compatible with acoustic ratings up to STC51. Higher ratings available upon request. |
| Hardware & Gasketing | Supplied with RF gasketing essential to shielding performance. Supports a range of hardware from standard to high-security. 70dB assembly requires surface-mounted hardware. |
Frame Options:
Welded Frames
- One-piece construction ideal for new builds or major renovations
- Factory-welded for strength and continuous shielding
- Most cost-effective option
Split Frames
- Two-piece retrofit-ready design clamps around existing drywall/stud openings
- Ideal for live environments, fast-track projects, or minimal disruption
- Maintains shielding integrity while simplifying installation
Common Applications
- Data Centers & Server Rooms – RF containment without compromising design
- Government Offices & Secure Meeting Rooms – For discreet protection adjacent to SCIF zones
- Military Facilities & Intelligence Centers – Secure briefings and classified zones
- Telecom & Utility Control Rooms – Minimizes RF leakage in operational facilities
- Corporate R&D Spaces – Protects IP while preserving architectural continuity

The relationship between the door, seal and frame is absolutely critical and the presence of finish paint between the seal and the door face can pose a serious problem. In short, the presence of finish paint can create a barrier between the various parts of the assembly. The matter can be addressed in one of three ways: the use of an unpainted door face such as stainless steel, the absence of paint on a mild steel door face, the use of RF tape that can be applied to the door face where it contacts the perimeter seal.
Yes, different makes/models of hardware can profoundly affect the product’s performance. As well, perimeter and bottom seals are an integral part of an RF-Shielding door assembly’s performance and must be supplied as per the performance requirements and configurations tested by AMBICO. In the common case of acoustic performance being specified with radio frequency reduction, the seal system can be modified accordingly. The project hardware consultant should always coordinate closely with AMBICO.
