The Cornerstone to Our Success
Our Hollow Guide Rail TK3 TK5 are high-performance elevator components designed with a rectangular hollow section and flat edges (non-flanged). These guide rails are specifically tailored for TK Elevator systems and are widely used in machine room-less (MRL), residential, and commercial elevators. Compared to traditional solid or flanged guide rails, the hollow + flat-edge design delivers a lighter structure, easier installation, and precise compatibility with elevator cars and counterweights in TK-branded systems.

Hollow guide rails are designed with a box-type or hollow cross-section instead of a solid one. This smart design brings several practical advantages.
First, they are lighter in weight, reducing the load on the elevator shaft by 20%–30%. This helps improve energy efficiency, especially during acceleration and braking, and reduces wear on key components.
Despite being lighter, hollow rails still offer strong stiffness and stability. Their design helps absorb vibration and reduce noise during elevator operation, creating a smoother and quieter ride—something passengers and building owners both appreciate.
They’re also easier to install and maintain. Lighter weight means less labor and equipment are needed for installation. Plus, the hollow space allows for neatly hidden wiring or sensors, which supports smart monitoring without affecting the appearance or increasing dust exposure.
For high-speed or high-rise elevators, hollow rails help spread out stress more evenly during emergency stops. In residential elevators, they help minimize noise and swaying, improving everyday comfort.
In addition, hollow rails are more sustainable. They use less material, are easier to recycle, and provide room for future upgrades—such as embedded sensors or smart features—making them ready for the next generation of intelligent elevator systems.
Thus, hollow guide rails are not just lighter—they're smarter, quieter, easier to work with, and better prepared for the future.
According to international standards: ISO7465:2007; ISO630: 2021. According to international standards, conduct comprehensive testing of raw materials based on the material certification provided by suppliers to ensure that the quality of each batch of raw materials meets the requirements.
Configure two automated guide rail production lines. The equipment must ensure that the produced items comply with or exceed customer requirements while maintaining the stability of straightness, distortion, and surface roughness
Given the stringent requirements for straightness and twist in BE grade guideways, specialized automatic straightening and twist correction equipment, along with advanced detection systems, have been implemented. The straightness is maintained within 0.5 mm, while the twist is controlled to within 30' per meter
The service concept of "customer first" asserts that, regardless of where our services are delivered—be it within the company, at the client's workplace, on the construction site, or during transportation—our primary objective remains to satisfy the client
