When the cold northern wind sweeps across the frozen surface of Wangjiawan, an ice - themed landmark boasting both aesthetic appeal and functional strength officially reveals its true look — the "Cloud - Shrouded Ice Jade" Speed Skating Hall of Shenyang Wangjiawan Ice Sports Center, which our company participated in designing and constructing, has been fully completed! The arrival of this milestone not only injects strong impetus into the development of ice - snow economy in Liaoning and Shenyang and the revitalization of Northeast China, but also marks Sanxin Industry's persistent craftsmanship and technological breakthroughs in the field of high - end roofing systems. With the successful completion of the "Cloud - Shrouded Ice Jade" project, Sanxin's roofing waterproofing technology ushers in a brand - new chapter.

Looking back on the project's progress, from the practice of the philosophy of "Revitalizing Enterprises Through Science and Technology, Serving the Motherland Through Industry", to the efficient performance in overcoming the challenges during the 78 - day rainy season, and now to the perfect completion of "Cloud - Shrouded Ice Jade", Sanxin Industry has always taken products as its core competitiveness, building an indestructible, green and energy - saving "aerial barrier" for this ice - snow venue. As a backbone enterprise of the Metal Roofing Technology Branch of China National Building Waterproof Association, Sanxin Industry has been deeply engaged in the industry for many years. Relying on its persistent pursuit of and outstanding contributions to the waterproofing cause, it has long established a leading position in the industry. From Changchun Zhibo to Shenyang's "Cloud - Shrouded Ice Jade", the completion of each benchmark project is like a glittering Jinyu Trophy, endowing the company's technological strength and brand reputation with a brilliant golden luster.

The successful completion of this "Cloud Ice Jade" project is inseparable from Sansin Industrial's all-round breakthroughs and decisive contributions in the field of roofing technology. In response to the high-standard requirements of the project, the company's team started with innovations in modular structural design. Through precise technical parameter model simulations and rigorous wind uplift resistance tests and verifications, they finally determined the optimal roofing technical scheme. During the production and installation of the roofing units, the technical team overcame difficulties by disassembling the complex roof into standardized units. Relying on intelligent factory prefabrication and prefabricated construction modes, they significantly improved construction efficiency and precision, which not only avoided the risks of construction during the rainy season but also ensured the project quality. This full-process solution integrating design, production, and installation not only demonstrates Sansin Industrial's strong technical strength but also provides a reference industry benchmark for the construction of similar ice and snow venues.

Dual authority inspection + triple core advantages, building a solid "all-round defense line" for northern roofs

In response to the climatic characteristics of severe cold, strong winds, and heavy snowfall in northern winters, the unitized modular roof system customized by Sanxin Industrial has undergone water tightness and wind uplift resistance tests by a northern testing company (dual authoritative tests). Its core indicators far exceed industry standards such as the "Code for Quality Acceptance of Building Roof Engineering", providing authoritative endorsement for the product's performance. Meanwhile, with the three core advantages of "strong weather resistance and durability, first-class waterproofing and wind resistance, energy-saving insulation + ultra-low energy consumption", it is fully adapted to the complex climate in the north. This system is by no means a simple拼接 of materials, but a masterpiece of craftsmanship integrating multiple innovations:

Advantage of strong weather resistance and durability

High-quality base materials suitable for the northern climate are carefully selected. Stainless steel has strong weather resistance and is not easy to rust. Aluminum panels are paired with fluorocarbon coatings with excellent weather resistance, which can maintain their appearance and structural strength even when exposed for a long time, avoiding brittleness, cracking and aging caused by severe cold and exposure to the sun, and maximizing durability.

Advantage of waterproofing and wind resistance

Innovatively adopting metal-integrated polymer waterproofing technology and a unique photovoltaic connection mechanism for seamless connection, the waterproof, thermal insulation and sound insulation performance have achieved a qualitative leap, completely solving the problem of roof leakage in cold regions. The roof panels are manufactured using a factory-integrated composite forming process. The outer waterproof membrane is closely integrated with the inner protective material, combined with hot-melt welding and multiple sealing designs, with no exposed screws. The waterproof level reaches the first-class standard, and the wind uplift resistance performance far exceeds the specification requirements, remaining as stable as a rock even at a height of 38.4 meters.

Advantage of energy-saving insulation + ultra-low energy consumption

The roof is built with a high-density insulation layer and professional sound-absorbing and vapor-barrier materials, with a thermal conductivity much lower than conventional standards. It can not only firmly lock the indoor temperature, significantly reduce energy consumption for cooling and heating, but also isolate external noise and keep the venue dry. It not only conforms to the "dual carbon" concept, but also saves costs for the long-term operation of the venue, truly achieving both greenness and practicality.

Core patents empowering + efficient performance, defining a new benchmark for modular roofing

Relying on core patents such as "Performance Optimization Method and System for Unitized Modular Roofing", Sanxin Industrial has fundamentally optimized the connection and sealing processes of the roofing system, completely solving the three major pain points of traditional roofing: easy leakage, poor wind resistance, and high energy consumption.

The digital modular unit design breaks through the limitations of traditional construction by disassembling complex roofs into standardized units, laying the foundation for efficient assembly. The revolutionary factory intelligent prefabrication and prefabricated construction model significantly reduces on-site work volume, not only avoiding the risks of construction during the rainy season but also ensuring construction accuracy and environmental protection requirements. In the end, the efficient installation of hundreds of units was completed, overcoming the construction challenges in special areas, and laying a solid foundation for the project's completion with strength. The roof panel has a warranty period of up to 25 years, further confirming the reliable quality of the product. This solution, which combines innovative technology and practical value, has also become the core blueprint for defining the project's roofing standards.

Completion is not an end, but a new beginning.

The full completion of "Cloud Ice Jade" is a high recognition of Sanxin Industry by the owner and the supervision unit, and a vivid manifestation of the company's technical strength and brand influence. From product research and development iteration to intelligent prefabrication and precise installation, Sanxin Industry has polished every detail with ingenuity. The roof system created integrates multiple advantages such as strong protection, high energy efficiency, ultra-low energy consumption, and durability, and will continue to safeguard the Wangjiawan Ice Sports Center in hosting major ice events and daily operations.

In the future, Sanxin Industry will continue to uphold the corporate philosophy of "Innovation, Quality, Integrity, and Service", empower the construction of more landmark projects with more core technologies and high-quality products, continue to lead in the field of high-end roof systems and waterproofing, and contribute more Sanxin strength to the development of the industry and national infrastructure construction!
