Width of Prefabricated Panels in Old Houses

The width of prefabricated panels in old houses generally ranges from 30 cm to 600 cm, with common specifications including 300 cm, 400 cm, 500 cm, and 600 cm. Among these, prefabricated panels for residential use predominantly feature widths of 500 mm and 600 mm.

The width range of prefabricated panels in old houses is broad, primarily depending on their type and purpose. According to available data, the width of prefabricated panels typically falls between 30 cm and 600 cm, but in practical applications, the more common specifications are concentrated at 300 cm, 400 cm, 500 cm, and 600 cm. Among them, the widths of prefabricated panels used in residential buildings are most commonly 500 mm (50 cm) and 600 mm (60 cm). These two specifications can meet the span requirements of most living spaces while balancing structural stability and material economy.

In terms of specific types of prefabricated panels, different designs have varying width requirements. Hollow-core panels are a common structural form in old houses, with a mainstream width of 0.5 meters (50 cm). This design reduces self-weight through internal hollow structures while maintaining sufficient load-bearing capacity, making it suitable for floor slabs or roof panels. Channel-shaped panels typically have a width of 0.9 meters (90 cm), with a channel-shaped cross-section that enhances bending resistance by increasing the cross-sectional height, often used in public buildings or industrial plants with large spans. Solid flat panels commonly have a width of 0.6 meters (60 cm). Due to the absence of internal hollow structures, they have higher overall strength but greater self-weight, making them suitable for special scenarios with stringent load-bearing requirements.

Additionally, some old houses may use non-standard prefabricated panels with widths less than 30 cm or greater than 600 cm, but such cases are relatively rare. For example, early experimental buildings or special-purpose rooms may adopt customized dimensions, but the application scope of extreme specifications is limited due to transportation and installation constraints.

Overall, the selection of prefabricated panel widths in old houses requires comprehensive consideration of building type, span requirements, material properties, and construction conditions. In the residential sector, 50 cm and 60 cm are predominant, while industrial or public buildings may adopt wider specifications based on actual needs. Understanding these data helps assess the structural safety of old houses or select matching replacement materials during renovations.
