Product details

Door frame assembly is a special integrated structural component for door installation of metro cars and EMUs. As a core supporting part of the door system for rail transit vehicles, it is mainly used for precise installation and positioning of the door system and connection to the vehicle body structure. It is a key component ensuring smooth door opening/closing and reliable body sealing safety, and is widely applicable to the supporting production of door systems for urban rail vehicles worldwide.

This product uses special shaped pipes and profiles as the core material, formed by high-precision riveting and welding processes as well as welding machining. It features high strength, fatigue resistance and high precision, meeting the requirements of long‑term, high‑frequency opening and closing of door systems.

In the vehicle body structure, the Door frame assembly connects seamlessly with structural parts such as side beam and door pillars to build a stable door installation frame, guaranteeing installation accuracy and body structural strength. Meanwhile, it reserves reasonable installation space for in‑vehicle parts including grille and drain pipe, realizing coordinated operation between the door system and the full‑vehicle functional systems.

Adopting a customized design, the product can be adjusted in structural specifications according to door dimensions and opening modes of different vehicle models, suitable for door installation of various metro cars, EMUs and low‑floor trams.

In compliance with overseas market standards, this product strictly follows EU and international rail transit industry safety regulations. It adopts corrosion‑resistant, high‑strength steel with anti‑corrosion surface treatment, adapting to diverse regional climates without rusting or deforming during long‑term use, ensuring stable operation of the door system.

The whole production process is under quality control; profile cutting, welding machining and dimensional inspection all use precision equipment to meet the highest industry standards for installation accuracy.

As the core integrated component of the door system, the quality of the door frame assembly directly affects the vehicle’s sealing performance, sound insulation effect and operational safety. We possess mature processing and welding technologies for special shaped profiles, providing one‑stop services from design and production to testing.

We also produce supporting parts including side beam and door pillars, offering overseas customers an integrated solution for door system components.

We focus on supplying high‑quality integrated structural parts to global rail transit clients. Our Door frame assembly stands out for precise positioning, high strength, durability and strong customization, making it the top choice for overseas vehicle manufacturers and door supporting enterprises.

We provide long‑term stable supply, technical support and personalized customization, helping customers improve door system quality and vehicle operation safety.
