House Line Prefabrication

House line prefabrication comes in various types, with distinct characteristics in terms of price, manufacturing processes, and application scenarios.

From the perspective of price, the price range of house line prefabrication products is quite wide. Taking architectural decorative cement components as an example, the prices of prefabricated components such as shallow-groove vertical-grain GRC lines range from ¥10.45 to ¥958.2, mainly influenced by factors such as material, design complexity, and manufacturer differences. For instance, simple lines made of ordinary cement are relatively inexpensive, while lines made of high-strength GRC (glass-fiber-reinforced concrete) with intricate carvings or three-dimensional shapes have significantly higher prices due to increased material costs and processing difficulty.

In terms of process types, prefabrication technology encompasses various forms.

1. Modular prefabrication: This is an advanced form of prefabricated construction, where an entire building is divided into independent modules (such as room and corridor units). The main structure, utilities, and interior and exterior decorations are completed in a factory. After being transported to the site, the modules are quickly assembled using bolts or welding. This technology significantly shortens the construction period, reduces on-site wet work and construction waste, but requires precise design of module interfaces and transportation plans.
2. Reinforced concrete prefabricated lines: For parts such as eaves, lines with tie bars are prefabricated in the factory in advance. During installation, they are tied with the reinforcement of the main wall and then poured together. Compared with traditional cast-in-place processes, this method eliminates the need for external formwork, reduces the risk of high-altitude work, and is particularly suitable for high-rise buildings or eaves designs with complex shapes.
3. Iron-wire-reinforced cement prefabricated lines: Through mold-forming processes, iron wire mesh or single iron wires are embedded in cement mortar to enhance the crack resistance and structural strength of the lines. This technology is commonly used for decorative components (such as window surrounds and waistlines), ensuring both造型 (shape) accuracy and reduced material costs.

Regarding application scenarios, prefabricated lines are widely used for building facade decorations and structural connection reinforcement. For example, GRC lines are lightweight, strong, and highly malleable, making them suitable for complex shapes such as pediments and capitals in European-style buildings. Reinforced concrete prefabricated eave lines focus more on reliable connections with the main structure and are commonly used for roof eaves in residential and commercial buildings. Modular prefabrication technology is mostly used for rapid construction projects such as affordable housing and hotels.

When selecting prefabricated lines, it is necessary to comprehensively consider factors such as project budget, design requirements, and construction conditions. Priority should be given to products from regular manufacturers that comply with national standards (such as GB/T 19681-2005 Architectural Decorative Lines) to ensure quality and safety.
