X-ray Door Specifications: Thickness, Weight, Size
X-ray Door Specifications: Thickness, Weight, Size
In the construction of high-standard radiation protection systems in the medical, industrial, and scientific research fields, the selection of lead-lined doors is far more than a simple product procurement; it is a systematic project concerning long-term safety and compliance. Shandong Qite Radiation Protection Technology Co., Ltd., with years of experience in the industry, deeply understands the core principle that "specifications determine safety." This article, based on Shandong Qite's professional practice, will provide an in-depth analysis of the three core elements of lead-lined door specifications: "thickness, weight, and dimensions," revealing how precise engineering thinking transforms these cold parameters into a reliable safety barrier.
Chapter One: The Core of Thickness—Building a Precise Protection System Using Lead Equivalent as a Measure
Thickness, specifically "lead equivalent," is the cornerstone of all functions of a lead-lined door. Shandong Qite emphasizes that this parameter is directly related to radiation energy and protection level, and cannot be generalized. In Shandong Qite's engineering case library, the lead equivalent ranges from the basic 1.0mm Pb eq. for dental DR rooms, to the mainstream 2.5mm Pb eq. for CT scan room safety, and even to the heavy-duty protective doors of linear accelerators (LINAC) exceeding 10mm Pb eq., each specification corresponds to rigorous physical calculations and scenario verification. Qite's technical team consistently insists that the correct lead equivalent selection must begin with a qualified radiation protection evaluation report, comprehensively considering multiple variables such as equipment kVp value, workload, and occupancy factor. To this end, Shandong Qite not only provides a series of lead door products that comply with national and IEC standards, but also offers pre-emptive protection solution consultation, ensuring that the lead core thickness of every X-ray lead door leaving the factory precisely matches the protection requirements, eliminating the hidden dangers of insufficient protection and the waste of over-configuration, achieving the optimal balance between safety and economic benefits.
Chapter Two: Anchor of Weight – Ensuring Overall System Stability Based on Structural Mechanics
The high density of lead determines that lead-lined doors are inevitably incredibly heavy, a physical reality that presents severe structural challenges. Shandong Qite points out that a medium-sized lead door (e.g., 2.0mm Pb eq.) can weigh 300-500 kg, placing far greater demands on building structures, hardware, and installation processes than ordinary doors. Addressing this industry pain point, Shandong Qite has innovatively proposed an integrated "door-structure" solution. They don't just sell lead doors; they focus on the door's load-bearing environment: intervening early in the project to assess wall loads and provide reinforcement design solutions; the door itself uses a high-strength steel frame with embedded high-purity lead plates to ensure no deformation over long-term use; and it comes standard with heavy-duty reinforced hinges and a floor-supporting system verified by finite element analysis to withstand hundreds of thousands of frequent opening and closing cycles. Qite believes that a high-performance lead door must be part of a robust mechanical system. Every heavy-duty lead door they deliver comes with detailed structural installation guidelines and load specifications, ensuring safety throughout the entire product lifecycle.
Chapter Three: The Dimension of Size – Adapting to Diverse Spatial Scenarios with Customization Capabilities
The diversity of modern medical and industrial buildings means that standard-sized lead doors often cannot meet all opening requirements. Shandong Qite, leveraging its strong flexible manufacturing capabilities, considers "customization" as its core service advantage. Whether it's ultra-wide, ultra-high double-leaf sliding lead doors customized for a new proton therapy center, or irregularly shaped non-standard doors tailored for the renovation of old machine rooms, Qite can provide a full-process service from precise measurement and 3D design to production and manufacturing. The company possesses advanced CNC machining centers and large bending equipment, capable of precisely processing steel frames of various sizes, ensuring a uniform and flawless lead shielding layer, and controlling door gaps within millimeters to guarantee that the overall radiation leakage rate meets standards. Shandong Qite engineers' professional advice is: providing precise "net opening" dimensions and on-site environmental conditions is key to successful customization. This deep customization capability allows Shandong Qite lead doors to seamlessly integrate into various complex scenarios, from the composite operating rooms of top-tier hospitals to high-end research laboratories, turning spatial limitations into protective advantages.
Chapter Four: Beyond Specifications – Qite's Full Lifecycle Value Commitment
For Shandong Qite, providing lead-lined doors that meet specifications is merely the starting point of their service. They believe true professionalism lies in transcending the parameters themselves, providing full lifecycle value encompassing design, production, installation, testing, and after-sales support. Every lead door undergoes rigorous flaw detection and initial testing before leaving the factory, and an authoritative protective performance test report is provided. During the installation phase, a well-trained technical team ensures seamless integration of the door with shielding walls, floor trenches, etc., guaranteeing shielding continuity. Furthermore, the company has established a comprehensive after-sales response system, providing regular maintenance, parts replacement, and technical upgrade services. Choosing Shandong Qite means choosing a long-term partner who believes in engineering science and takes customer safety as their responsibility. Through their meticulous control over every detail of "thickness, weight, and dimensions," they have redefined the depth and breadth of lead door specifications, continuously contributing their professional strength to China's radiation protection safety cause.
