Tianjin Greatmen Building Decoration Engineering Co., Ltd. was established in 1995 and is a company specializing inR&D and Engineering Applications of High-Efficiency Thermal Insulation Door and Window Systemsa national-level high-tech enterprise centered on
Since 2008, the company has continuously focused onIntegrated Aluminum Alloy Energy-Efficient Door and Window Systemtechnology research and development, focusing on key performance factors such as building thermal insulation, air tightness, water tightness, and wind-pressure resistance, and has developed multiple proprietary intellectual property rights and core patented technologies. Independently developed by the company, the GM Integrated Aluminum Alloy Energy-Efficient Door and Window System, and has been tested by several national-level testing institutions, demonstrating thermal insulation and wind-pressure resistance performance significantly superior to comparable products in the industry.
As a company with long-term service togreen buildings, passive low-energy buildings, and major engineering projectssystem door and window enterprise, Greatmen not only participates in the development and revision of numerous national and industry standards, but also continuously introduces industrialized manufacturing, the Internet of Things, and intelligent processing technologies into the door and window industry, driving door and window systems towardupgrading toward high performance, systemization, and Industry 4.0。
Addressing the overall performance requirements for building envelopes in passive low-energy and green buildings, we redefine the structure and functionality of aluminum alloy doors and windows at the system level.
Through the systematic integration of profile structures, thermal insulation configurations, air- and water-tightness systems, and installation details, we have built aIntegrated Aluminum Alloy Door and Window System。
Our product system is not merely a combination of individual window types. Centered on building performance, it also considers stability, durability, and long-term operational performance, meeting application needs across different climate conditions and building standards while providing reliable, sustainable door and window solutions for buildings.
We have long served passive low-energy buildings, green buildings, and high-standard construction projects, supporting system selection, technical coordination, and customized solutions to enhance overall building performance.
Our understanding of titanium alloy window systems stems from our ongoing exploration of the relationship among materials, structures, and architectural spaces.
A product's value lies not only in its performance specifications, but also in its long-term stability in real-world building environments.
The standards by which we measure our work have always centered on two core dimensions:
Customers' real-world experience during useand
the overall compatibility of door and window systems in terms of safety, durability, physical performance, and overall architectural aesthetics。
Years of technical expertise and engineering practice have made our titanium alloy window systems a trusted reference choice in the field of high-performance buildings.
We have always remained committed tobalancing technical reliability, sound design, and engineering feasibility
The inherent advantages of titanium alloy in strength, stability, and durability are the starting point for our window and door system design.
Since beginning the research and development of titanium alloy window systems, we have consistently focused on the core requirements of building envelopes and systematically restructured window and door design.
By combining lightweight design with modular construction,
While ensuring structural safety and wind pressure resistance, this approach also gives the window system excellent adaptability and long-term operational stability.
Ongoing research and development and technical optimization drive product evolution.
We continuously explore structural design, joint detailing, and system integration,
to ensure that titanium alloy window systems consistently deliver reliable and controllable performance across different building types and operating environments.
In 2008, the company began developing and designing highly energy-efficient, thermally insulating windows and doors. To date, it has developed multiple products with independent intellectual property rights. The company's independently developed GM integrated aluminum alloy energy-efficient window and door system has undergone testing by multiple national-level inspection institutions for thermal insulation, wind pressure resistance, and a range of other technical and standard performance criteria, with all results meeting relevant national standards. In particular, its thermal insulation and wind pressure resistance performance greatly exceed the corresponding indicators of comparable products in the industry. The system has also obtained multiple utility model and invention patents. In 2012, the product passed the Ministry of Housing and Urban-Rural Development's Evaluation of Scientific and Technological Achievements in the Construction Sector; in 2013, it received the Ministry's Kangju Certification; on July 12, 2014, it obtained the Four New Technologies Evaluation Certificate for the construction and transportation sector issued by the Tianjin Municipal Commission of Construction and Transportation, and in the same year was included by the Ministry of Housing and Urban-Rural Development in the Directory of Promoted Scientific and Technological Achievements in the Construction Sector. That year, the company also joined the Ministry's Residential Industrialization Alliance as an executive council member, and the product was included in the Green Building Product Selection Directory of the Tianjin Eco-City Green Building Research Institute. In 2015, following expert review, it joined Beijing's High-Quality Components Catalog for Affordable Housing. In 2016, it was invited to join the Ministry's Strategic Alliance for Technological Innovation in the Passive Low-Energy Building Industry following expert review; that same year, it passed the approval process and received the Certificate for the Promotion of Scientific and Technological Achievements issued by the Tianjin Municipal Commission of Housing and Urban-Rural Development. In 2017, it was invited to join the drafting group for the standard Test Methods and Evaluation Requirements for Fire Resistance Integrity of Building Windows and Doors. In 2019, it was invited to join the revision group for the standard Code for Sound Insulation Design of Civil Buildings and participated in the comprehensive revision of its 2019 edition.
Leveraging titanium alloy'sHigh strength, durability, and structural stabilityWith inherent advantages in these areas, titanium alloy window systems can maintain reliable structural performance and stable operation over long-term use.
Through systematic profile design, structural optimization, and connection detail integration, these window systems can effectively meet the demands of varying climatic conditions, wind loads, and complex building environments.
Compared with traditional windows and doors, titanium alloy window systems place greater emphasis onthe synergy between structural safety, long-term operational stability, and overall building performance, making them suitable for building types with demanding envelope requirements and widely applicable to high-standard residences, public buildings, and specialized projects with stringent durability and safety requirements.
Through coordinated operations across multiple bases, we have achieved efficient integration among R&D, processing, assembly, and engineering applications.
This manufacturing model not only increases overall production capacity and responsiveness, but also provides greater flexibility and reliability for complex engineering projects and customized requirements.
We have always regarded product compliance and technical standards as integral components of high-performance window and door systems.
Through long-term R&D, manufacturing, and engineering applications, the company's products have obtained multiple relevant national and industry certifications and have continued to participate in the development of technical specifications and standards for the construction sector, ensuring that our window and door systems meet stringent requirements for safety, performance stability, and engineering applicability.
These certifications and qualifications not only recognize our existing achievements, but also affirm our technical direction, quality management, and commitment to long-term sustainable development.
