Pre-engineered buildings (also known as prefabricated buildings) can be categorized by multiple dimensions, with further subdivisions under each classification. The core classification system is as follows:
Classification by structural materials
This is the most mainstream classification method in the industry, covering the current predominant types of pre-fabricated buildings:
Prefabricated concrete structure buildings: With prefabricated concrete components (beams, slabs, walls, columns, etc.) as the core, this is the most widely used type in domestic residential and public buildings, which can be further classified into subtypes such as monolithic prefabricated and fully prefabricated concrete structures.
Prefabricated steel structure buildings: Featuring steel components as the primary load-bearing system, they are lightweight, highly ductile, and suitable for high-rise buildings, industrial plants, hotels, and other scenarios, including subtypes such as prefabricated steel frames and box-type steel structures.
Prefabricated timber structures: With prefabricated wooden components as the core, they are highly environmentally friendly and widely used in low-rise residential buildings in Europe and America, while commonly applied in cultural tourism and low-rise homestay projects domestically.
Other derivative types also include subcategories such as prefabricated light steel structure buildings and prefabricated composite material buildings (hybrid structures combining steel, light steel, and concrete).
Categorized by component integration level and construction form
Classification based on the degree of integration of prefabricated building units is a common logical approach in engineering practice
Panelized prefabricated construction: Using precast wall panels and floor slabs as core components, it can expand the usable area of buildings but offers relatively limited design flexibility. Early "large-panel housing" systems fall into this category.
Frame prefabricated construction: Utilizing precast beams and columns to form a load-bearing frame, combined with precast floor slabs and wall panels, it offers high flexibility in interior space, making it suitable for buildings requiring large open areas such as offices and schools.
Box-type (modular) prefabricated buildings: Complete functional rooms are used as prefabricated units, with walls, plumbing, electrical systems, and decoration integrated in the factory. These units are then directly assembled on-site, increasing construction speed by 50%-70%, but requiring higher standards for transportation and lifting equipment.
Other supplementary classification dimensions
Classification by building height: It can be divided into low-rise, mid-rise, high-rise, and super high-rise precast buildings, with different height categories corresponding to different structural system selections.
Classification by Prefabrication Rate: It can be divided into five levels: ultra-low prefabrication rate (0%-5%), low prefabrication rate (5%-20%), ordinary prefabrication rate (20%-50%), high prefabrication rate (50%-70%), and ultra-high prefabrication rate (above 70%). Box-type prefabricated buildings generally achieve a prefabrication rate of up to 85%, falling under the ultra-high prefabrication rate category.
According to the concrete structural system, it can be further subdivided into subtypes such as assembled integral frame structures, assembled integral shear wall structures, and assembled integral frame-shear wall structures, catering to diverse architectural functions and height requirements.
