Baoshan Prefabricated Assembly-type Housing

Baoshan's prefabricated assembly-type housing is developing rapidly, mainly featuring two types: composite steel mesh and light steel structures, each with distinct characteristics in project applications and structural advantages.

Project Overview

In the first quarter of 2026, the Baoshan Housing and Urban-Rural Development Bureau publicly reported that the newly started construction area of prefabricated buildings in the city increased by 38.6% year-on-year, with social housing, schools, and hospitals accounting for over 65% of the total. The Yunnan Provincial Housing and Urban-Rural Development Department has designated Baoshan as a pilot city for deepening the application of prefabricated buildings in western Yunnan, tracking 17 proposed and ongoing projects that clearly adopt prefabricated technology paths. Among them, 12 have entered the late stages of survey and design, and 5 have initiated the solicitation of general contracting intentions for construction. Projects funded by the government for public buildings, industrial park carriers, and state-owned enterprise-led developments are sending clear signals, with over 70% of the projects concentrated in Longyang District, Tengchong City, and Shidian County.

Structural Types and Advantages

• Composite Steel Mesh: This belongs to the "prefabricated shear wall" structure. During factory prefabrication, double-layer steel mesh sheets are welded into shape, with positions reserved for insulation layers and pipelines. On-site, the steel meshes are assembled and then the entire structure is poured with concrete to form walls. Its advantages are significant: Strong earthquake resistance: It forms an integrated load-bearing system, with earthquake resistance far exceeding that of traditional brick-concrete structures; Fast construction: The main construction period can be shortened by 30%-50%; Comfortable living: The walls come with built-in insulation layers, effectively addressing the issues of large temperature differences between winter and summer and humidity during the rainy season in Yunnan; High usable floor area: For the same construction area, the indoor usable area can be increased by approximately 8%-10%; Controllable quality: Reputable manufacturers provide "one-stop" services from design to after-sales, with even the main structure covered by a lifetime warranty. In terms of comprehensive costs, considering the labor savings from shortened construction periods, its overall cost can be 15%-30% lower than that of traditional brick-concrete structures. It is suitable for 2-3-story rural self-built houses, villas, homestays, township residences, and small public buildings. For buildings of 4 stories or more, special calculations and demonstrations by professional structural design units are required.
• Light Steel Structure: This uses steel as the main load-bearing component, employing materials such as cold-formed thin-walled steel or high-frequency welded H-shaped steel. It features light weight, high strength, and good earthquake resistance, effectively reducing the cost of building foundations; Fast construction speed: Most components are processed and manufactured in the factory, requiring only simple assembly and connection on-site. Many projects can complete the main construction within 3-6 months; Excellent environmental performance: It mostly uses recyclable steel, generating less construction waste during the building process, with low construction noise and dust; Good thermal insulation, heat retention, and sound insulation: The walls can be filled with insulation cotton, sound insulation cotton, and other materials, meeting the different functional needs of family residences, offices, and commercial spaces.
