Recently, Shenyang Sanxin Industry Co., Ltd. has brought exciting news — in the fierce market competition, relying on its excellent comprehensive strength and profound technical accumulation, the company successfully won the bid for the professional subcontracting project of the roof of the National Speed Skating Hall in Shenyang Wangjiawan Project. This is not only a high recognition of our professional capabilities, but also an important milestone for us to help Shenyang build an international ice sports highland!

Project Overview 01
A huge ice structure carrying the city's dreams

The Shenyang Wangjiawan Project is located in Wangjiawan, Hunnan District, adjacent to the Hunhe River. It is a super project integrating sports competitions, cultural exchanges and urban landmark functions. With a total construction area of approximately 263,800 square meters, the project includes three core buildings: an ice sports complex, a speed skating hall, and a media center. Adopting the design concept of "Ice Jade on Clouds", it perfectly integrates the city with nature, and architecture with sports. Among them, the National Speed Skating Hall, as one of the core venues of the project, has a construction area of about 135,700 square meters and a height of about 39.5 meters. It takes the "cuboid" as the basic form, with its corners opening to the surroundings. The facade outlines a sculptural sense along the banks of the Hunhe River with dynamic arcs full of a sense of speed, and will become a venue for international top-level speed skating events in the future. After completion, the Wangjiawan Project as a whole will become a top ice sports event center in Northeast Asia, filling the gap of a modern ice and snow venue cluster in Liaoning and injecting new urban vitality into Shenyang.

Construction Difficulty 02
Pushing technical limits and solving multiple difficulties
As a large-scale ice-building in the cold region of Northeast China, the roof project of the National Speed Skating Hall faces many technical challenges:

- Climate adaptability issues: The Northeast region has severe cold and heavy snow in winter. The roof system needs to withstand extreme low temperatures, strong wind loads and the pressure of accumulated ice and snow. In particular, the electric tracing system of the drainage gutter must be precisely controlled to avoid the risk of freezing and blockage, ensuring the normal operation of the speed skating hall in cold weather.
- Complexity of multi-system collaboration: There are cross-operations of multiple systems such as sound-absorbing and thermal-insulating combined steel frame unit modules + metal TPO, factory-integrated load-bearing, thermal-insulating and waterproof systems, prefabricated roofs, photovoltaic devices, and pneumatic skylights. It is necessary to achieve seamless coordination between structural accuracy and functional connection. Any deviation in any link may affect the overall performance of the speed skating hall and even impact the holding of events.
- High standards for green energy conservation: As an important part of the ultra-low energy consumption building, the roof system must balance thermal insulation, heat insulation, and photovoltaic power generation efficiency, while meeting the intelligent control requirements of the pneumatic smoke exhaust skylight. It has a high degree of technical integration to match the green building positioning of the National Speed Skating Hall.

Our Advantages 03
Overcoming difficulties with professional strength
Faced with numerous challenges, Shenyang Sanxin Industry Co., Ltd. stands out with three core advantages:

- Profound technical accumulation: Having been deeply engaged in the construction field for many years, it has accumulated rich experience in the construction of roof systems for large public buildings, and is particularly good at the technical integration of metal roofs and photovoltaic integration projects in cold regions. It has participated in many provincial key projects, and has developed the "hard strength" to deal with complex working conditions, which is sufficient to meet the high-standard roof construction requirements of the National Speed Skating Hall. Sanxin's metal-integrated TPO composite unit roof system integrates innovative waterproof technology, digital modular unit design, and unique photovoltaic connection mechanisms, significantly improving the waterproof, thermal insulation, and sound insulation performance of photovoltaic roofs, especially with revolutionary advantages in factory intelligent prefabrication and prefabricated construction. The successful application of this system is of great significance to Liaoning's ice and snow industry and has created significant economic and social benefits.

- Strict quality control: A full-process quality management system from material procurement to construction acceptance has been established. Special testing standards for the wind resistance, waterproof and thermal insulation performance of the roof system have been formulated to ensure that every process meets the requirements of international event venues, providing protection for the high-quality construction of the National Speed Skating Hall.

- Outstanding innovation capability: It has a technical team led by senior engineers, which can optimize the construction plan according to the characteristics of the National Speed Skating Hall project. For example, special measurement technology has been developed for the installation accuracy of unit blocks within the cable range, providing guarantee for efficient construction and ensuring the roof project is completed on time and with good quality.

Winning the bid for the professional subcontracting project of the National Speed Skating Hall's roof is both a trust and a responsibility. Shenyang Sanxin Industry Co., Ltd. will adhere to the tenet of "building with exquisite craftsmanship and living up to the trust", set up a special攻坚 team, strictly follow the design standards, overcome technical difficulties, and strive to build the roof project of the National Speed Skating Hall into a high-quality project that can stand the test of time and international events. From blueprint to reality, from commitment to action, the people of Sanxin will interpret their responsibility with practical work, contribute to the brilliant completion of the National Speed Skating Hall in the Wangjiawan Project, and make this huge ice structure shine by the Hunhe River!
