Sany Heavy Industry Prefabricated Housing

Sany Heavy Industry holds significant technological advantages and extensive practical experience in the field of prefabricated housing (prefabricated construction), driving the development of building industrialization through the SPCS system, in-plane operation technology, and typical project applications.

1. SPCS Prefabricated Construction System: An Efficient Industrialized Construction Model
The SPCS technology system developed by Sany Group adopts a model of "hollow wall columns + equivalent heterogeneous structures + molds and fixtures + in-plane operations," with the core being the combination of factory-prefabricated components (such as hollow columns and composite slabs) with on-site post-pouring connections. For example, the Xingsha Yungu Experimental School project affiliated with Hunan Normal University achieved a 50% assembly rate using this system, with over 80% of the exterior wall area using ALC panels, significantly enhancing the level of industrialization. The system reduces on-site wet operations, shortens construction periods, and improves quality controllability through standardized design, factory-based production, and mechanized installation.

2. Vertical Structure and Enclosure Technology: Balancing Low Cost and High Performance
To address the issues of high cost and complex construction associated with traditional vertical prefabricated structures, Sany Construction Technology introduced the SPCS structural technology system, combined with ALC panel exterior enclosures, achieving advantages such as convenient production, reduced formwork, and low costs. The Xingsha Yungu Experimental School project validated its economic efficiency and waterproof performance, demonstrating that this technology can effectively reduce lifecycle costs while meeting building functional requirements.

3. In-Plane Operation Technology: Enhancing Safety and Efficiency
By utilizing fully prefabricated exterior walls and mold technology, Sany has eliminated the need for external scaffolding, transferring all construction activities to the interior of the structural plane. This innovation not only improves construction safety but also reduces labor and material costs. The technology has been applied in domestic projects in Changsha and Xi'an, as well as in the Jeddah Affordable Housing Project in Saudi Arabia (total area of 500,000 square meters), receiving high recognition from the industry, particularly for its outstanding performance in integrated thermal insulation and decoration construction.

4. Typical Projects Validate Technical Feasibility

• The Anhui Yuanding Lixin North Road Resettlement Housing Project used Sany's SFT250C tower crane to lift 3-4 ton prefabricated components, significantly improving the construction efficiency of a 7-story building.
• The Yungu Jiayuan Project achieved a 64.4% assembly rate across four high-rise buildings, utilizing the SPCS system for rapid delivery.
• The Jeddah Affordable Housing Project in Saudi Arabia, with a single building area of 5,000 square meters, completed exterior wall construction using in-plane operation technology, validating its adaptability in the international market.

5. Environmental and Efficiency Advantages: Aligning with the "Dual Carbon" Goals
Prefabricated construction reduces on-site noise and exhaust emissions, lowering lifecycle carbon emissions. Sany's technology further conserves materials and energy through large-scale production and mechanized installation, aligning with trends in green building development and providing technological support for sustainable industry growth.
