In Elevator Door Manufacturing
Strong Engineering and
Global Standards
Onuras has established a strong position in the sector with its robust engineering infrastructure, modern production technologies, and quality approach in accordance with international standards in the field of automatic elevator doors. The Quattrodoor brand, developed by Onuras, is designed to offer high performance, safety, and durability in the field of elevator doors and door mechanisms.
In central and telescopic elevator door solutions, Quattrodoor’s innovative mechanism structure adds value to projects by providing quiet operation, long lifespan, and low maintenance requirements. Onuras & Quattrodoor products, manufactured in Turkey, are preferred in many countries around the world today and are used reliably in global projects.
Thanks to our wide product range, engineering-focused approach, and continuously developing production capabilities, Onuras continues to be a reliable business partner in the elevator door sector.
About UsOur Production Process
Our production line is designed to produce high-performance elevator doors by combining engineering discipline, the use of modern technology, and quality control processes. Every step, from the welding stage to the testing laboratory, is carried out with safety, durability, and compliance with international standards in mind.
Welding Workshop
Metal parts are machined with high accuracy in our welding workshop. Each component undergoes special control processes for durability, safety and longevity before being made ready for assembly.
Assembly Line
Quattrodoor elevator doors and mechanisms are assembled step-by-step on our modern assembly lines. Thanks to our standardized production model, superior performance, trouble-free operation, and consistent quality are ensured.
Quality Control
Each product undergoes on/off cycle, durability, load, and vibration tests according to international standards. Long-term performance and safety are verified individually for all mechanical and electronic components.
R&D Unit
Onuras R&D team continuously produces innovative solutions to improve Quattrodoor door and mechanism technologies. Research, testing and development processes are carried out for quieter, safer, longer lasting and energy efficient systems.
High Production Capacity
Onuras, with an annual production volume approaching 50,000 doors, is positioned as one of the highest-capacity elevator door manufacturers in Turkey. All production processes are managed with modern automation infrastructure, CNC-supported lines, and precise quality control systems. Thanks to its extensive machinery park, metal processing, mechanical assembly, surface coating, and electronic integration processes are carried out under one roof with high accuracy. This structure ensures shorter delivery times, optimized stock management, and continuous supply assurance even in large-scale projects. Onuras’s production approach is not only focused on quantity but is also based on consistency, durability, and sustainable quality.
R&D-Centered Approach
OUATTRODOOR brand is the most visible face of Onuras‘s innovative vision. The R&D team conducts multi-layered studies ranging from acoustic improvement to vibration reduction, from motor torque optimization to control board development. Each new prototype is repeatedly tested against performance criteria such as door movement speed, opening and closing life, energy consumption, and emergency scenarios. Material engineering, electronic circuit design, and mechanical simulations are combined to develop faster, quieter, safer door systems. This comprehensive innovation culture makes Onuras not just a manufacturer; it becomes an engineering center that produces technology for the sector.
International Standards
Onuras’s production philosophy is based on the principle that safety must be measurable and verifiable. Therefore, all products are designed, manufactured, and tested in accordance with CE and EN81 norms, as well as all relevant industry standards. From mechanical strength tests to electronic protection circuits, from fire safety compliance to continuous operation simulations, every door undergoes control processes at the international laboratory level. All steel, aluminum, and electronic components used have traceability certificates. Thus, Onuras products can meet not only local needs but also the different requirements of different countries with the same level of safety.
Global Distribution Network
Onuras has a strong logistics capacity with its solution partners spread throughout Turkey and its export network extending to various regions of the world. Products are designed to maintain their performance in different climatic conditions – such as high humidity, low temperature, high temperature, and high usage frequency. Special packaging, fast spare parts supply, and technical documentation support are offered for international customers. The global network is not limited to product shipment; engineering teams guarantee sustainable quality by providing consultancy on door selection, installation optimization, and maintenance processes specific to the project. Thus, Onuras doors are preferred in a wide range of applications worldwide, from residential projects to hotels, industrial facilities to modern living spaces.
Documents & Quality Standards
Onuras documents its production approach, which fully complies with international safety norms in elevator doors and automation systems, with certifications. Compliance with CE and EN 81 standards shows that the products have been tested in accordance with European safety criteria and that each component meets high levels of strength, safety, and performance. All parts, from the materials used in the production processes to the electronic control units, undergo mechanical load tests, emergency safety scenarios, long-cycle life tests, and environmental durability analyses.
With its official certifications in quality management, safety compliance, and product performance, our company offers its customers not just a product, but a sustainable safety system. These documents also ensure that Onuras meets the technical requirements of the exporting countries, positioning it as a reliable manufacturer in the global market.
