Heavy Duty Lead Sliding Door

High-lead-equivalence sliding door for CT, interventional and high-workload imaging rooms

A reinforced sliding door carrying 2–4 mmPb lead shielding — engineered for the wider openings and higher workloads of CT scanners, interventional suites and linear-accelerator bunkers.

01 · Overview

Why Buyers Specify This Door

CT and interventional rooms demand wider openings for gantry and table access, and higher lead equivalence for sustained high-kVp workloads. A standard hinged lead door cannot span these openings — a reinforced sliding system is the answer.

The RAX Heavy Duty Lead Sliding Door uses a reinforced steel overhead rail with heavy-load nylon PA66 rollers to carry a leaf that can exceed 150 kg due to 2–4 mm of bonded lead. The track geometry ensures smooth travel despite the mass, and an optional servo operator provides hands-free automatic cycling for high-throughput imaging departments.

The lead sheet is continuous and overlaps the lead-lined frame by ≥ 20 mm on all sides, eliminating scatter leakage at the perimeter. A flush powder-coated or stainless face keeps the door cleanable and visually consistent with the clinical environment.

Lead equivalence (mmPb) is determined by the project’s shielding design report. RAX company facts are from the approved brand brief.

Why does a CT room need a sliding lead door?

CT gantries and patient tables require wider openings (1500 mm+) than a standard hinged leaf can span. A sliding door covers this width without the swing arc, and the reinforced rail carries the heavy lead-loaded leaf smoothly.

How heavy is the door leaf?

Depending on size and lead thickness, the leaf typically weighs 100–200 kg. The rail, rollers and operator are selected to carry this mass safely over 100,000+ cycles. We provide a structural load calculation for your lintel.

Can it be operated automatically?

Yes. A servo / VFD operator sized for the heavy leaf provides hands-free cycling with adjustable speed, soft start/stop and safety edges. Radar, push-button or access-control activation is supported.

What lead thickness is used for interventional suites?

Interventional and fluoroscopy suites with sustained high workloads typically require 3–4 mmPb. Your radiation physicist determines the exact value; we bond the corresponding thickness and verify coverage on the technical layout.

What is the lead time?

Sample 7–15 days; standard container 12–20 days; custom first order 20–35 days, repeat orders 15–20 days. FOB Tianjin or Qingdao, FCL and LCL supported.

What documents ship with the order?

Factory inspection report, structural load calculation, lead equivalence layout drawing, 100,000-cycle fatigue test record, FAI / pre-assembly photos, English installation manual + technical drawing, CE Declaration of Conformity, and export packing with traceable batch number.
