Recently, Jangho Curtain Wall successfully won the bid for the curtain wall sub-contract for the Jeddah Tower Project in Saudi Arabia, with a bid amount of 1.052 billion Saudi riyals (approximately 2.012 billion RMB), once again demonstrating Jangho Curtain Wall's leading position in the global curtain wall field.

Win the top of the world

Challenge the kilometer limit

The design height of Jeddah Tower exceeds 1000 meters, and after completion, it will surpass the 828 meter Burj Khalifa in Dubai, becoming the first great project in human architectural history to break through one kilometer height. The undertaking of the Jeddah Tower project this time is not only a manifestation of the strength of Jangho Curtain Wall, in challenging the limits of architecture and conquering the cutting-edge technology required for a one kilometer super high-rise curtain wall, but also another important milestone for "Chinese Construction" to shine globally.

Over the years, Jangho Curtain Wall has constructed over 1,000 landmark projects worldwide, each celebrated for its complexity, scale, and influence.Among them, there are more than 70 super high-rise skyscrapers over 300 meters and over 200 skyscrapers over 200 meters. In the field of the super high-rise curtain wall market, Jangho Curtain Wall not only has the world's largest market share, but has also created a remarkable industry legend: on average, one out of every three skyscrapers that rise from the ground shines with the ingenuity of "Jangho Manufacturing", making it a "cloud landmark creator".

Leading technology

Build the world's highest

Jeddah Tower is located on the coast of the Red Sea, and the curtain wall project faces a series of world-class technical challenges such as extreme weather conditions (high temperature, coastal location), huge wind pressure, structural deformation, and super high-rise construction, which puts the most stringent requirements on the design and construction of the curtain wall.

Jangho Curtain Wall was associated with the Jeddah Tower project as early as 2014. As the world's first enterprise to undertake the design of one kilometer super high-rise curtain walls, it took the lead in overcoming key technical challenges such as excessive wind pressure, excessive interlayer displacement of curtain walls, and durability of curtain walls in a coastal desert environment. It successfully completed the "five performance tests" of the curtain wall's air tightness, water tightness, wind pressure deformation, seismic performance, and thermal performance, with test parameters far exceeding the requirements of the American standard, laying a solid technical foundation for the project. In 2024, after the restart of the project, Jangho Curtain Wall won the bid again for design and technical services. Now, officially becoming a subcontractor for curtain wall engineering is not only a further verification of its technical strength, but also a strong export of Chinese technical standards to the international market.

Courageously venturing into 'no man's land' of architecture

and breaking new boundaries within the Curtain Wall Industry.

As the world's first one kilometer super high rise building, the construction of Jeddah Tower is not only an architectural miracle, but also an exploration of the limits of human engineering technology. Curtain wall construction faces unprecedented challenges: how to achieve efficient and safe transportation of unitised panels to a height of one thousand plus meters? How to ensure construction accuracy and personnel safety in extreme environments? How to coordinate the complex relationship between the curtain wall and the main structure in extreme temperature deformation and settlement? There is no mature experience to follow globally, making it a 'no man's land' that challenges the limits of engineering technology.

Faced with unprecedented challenges, Jangho Curtain Wall is guided by forward-looking design concepts, deeply applying cutting-edge technologies such as digitization and intelligence, and formulating a scientifically rigorous construction organization plan. In response to world-class construction difficulties such as vertical transportation, high-altitude operations, and integrated curtain wall structures, the company has explored practical and feasible innovative solutions, which will completely rewrite the construction rules of super high-rise curtain walls and lead the global super high-rise curtain wall technology into a new era.

Cloud based Green Revolution

Jangho curtain wall defines a new height of environmental protection

In response to the unique geographical environment and extreme climate characteristics of the Jeddah Tower project, Jangho Curtain Wall has tailored a green and sustainable curtain wall system solution that integrates safety, energy conservation, and environmental protection.

The project will adopt a unitised curtain wall system with excellent thermal insulation performance independently developed by Jangho Curtain Wall. Through advanced thermal insulation design and structural optimization schemes, it can effectively reduce the absorption of solar heat, reduce energy consumption by 30%, and achieve the maximum slimming effect on the exterior lines, effectively reducing the burden of energy consumption on the structure of super high-rise buildings and creating an energy-saving and environmentally friendly model for super high-rise curtain walls.

The one kilometer plus height of Jeddah Tower is both a challenge and an opportunity. The Jangho Curtain Wall will write an architectural legend on the top of the cloud with "Chinese technology". In the future, Jangho Curtain Wall will continue to lead the industry, allowing the light of Chinese construction to illuminate every skyline around the world.
