Four Steps to Plan a High-Performance Custom Shielded Room

A shielded room is a major engineering asset. Before design begins, our engineers confirm four critical requirements:

01

Survey Site Load Capacity and Clear Height

The steel structure, shielding panels and RF absorbers carry substantial weight. Confirm floor loading—typically more than 500 kg/m² for a custom installation—and the remaining clear height after fire-protection and HVAC systems are installed.

02

Define Standards, Frequency Range and Performance

Set the required frequency range from the applicable standards, such as CISPR, ISO or GJB. These requirements determine whether modular or welded construction is appropriate and define the absorber dimensions.

03

Specify the Shielded Door System

The door is the component most susceptible to performance degradation. Its size and mechanism—manual compression, powered sliding or fully automatic pneumatic sealing—must match the test object and material-handling method.

04

Coordinate Utilities, Fire Protection and HVAC

Power lines require high-power filters, ventilation needs honeycomb waveguide-below-cutoff panels, and the fire system generally requires clean-agent suppression. These provisions must be coordinated during engineering design.

Precision Engineering for Reliable Shielding Performance

1. Self-Supporting Frame and Cold-Rolled Steel Modular Walls

1. Self-Supporting Frame and Cold-Rolled Steel Modular Walls

A suspended or self-supporting modular frame uses high-quality, double-sided hot-dip galvanized cold-rolled steel panels. The structure resists deformation over long service periods and maintains stable sealing and damping performance.

2. Configurable High-Integrity Filtered Interfaces

2. Configurable High-Integrity Filtered Interfaces

High-performance fiber-optic waveguides, HVAC waveguide panels and a full range of high-power power/signal filters allow services to enter the room without compromising RF isolation.

3. Multiple Door Mechanisms with Anti-Pinch Protection

3. Multiple Door Mechanisms with Anti-Pinch Protection

Imported high-elasticity beryllium-copper fingers mate with precision dual knife edges around the door. Testing through up to 50,000 operating cycles helps prevent the high-frequency leakage common at moving seams.

1. Dual Knife-Edge Door with Two Rows of Beryllium-Copper Fingers

The shielded door is the moving opening most prone to RF leakage. Precision dual knife edges and conductive beryllium-copper fingers maintain low-resistance contact across a wide frequency range.

2. High-Attenuation Honeycomb Ventilation Panel

The honeycomb waveguide panel provides airflow and heat removal while exponentially attenuating electromagnetic waves below its cutoff frequency.

1. Centralized Wall Interface and Filter Decoupling

A centralized filter panel forms the only physical entry for power and signals. High-power low-pass filters and fiber-optic waveguides interrupt conducted electrical paths between the room and the outside environment.

2. Low-Dielectric Elevating Turntable and Quiet-Zone Alignment

The central elevating turntable uses low-permittivity materials with continuous height and rotation adjustment to position the device under test at the center of the quiet zone.
