Kunming Prefabricated Slab House Cover Plate

The cover plates for prefabricated slab houses in Kunming mainly include reinforced concrete prefabricated slabs and other types of prefabricated slabs. Details are as follows:

Reinforced Concrete Prefabricated Slabs

The reinforced concrete prefabricated slabs produced by Kunming Chuangxuan Cement Products Factory are commonly used modules or panels in engineering. They are manufactured and processed at the prefabrication yard and then transported to the construction site for installation.

• Dimensions: In terms of span, the longest for residential use is 4.2 meters, without a fixed modulus. Customization is required for spans exceeding this length. The widths are mostly 500mm and 600mm. The common thicknesses are 120mm and 150mm. The lengths generally follow a modulus of 300mm, such as 3000, 3300, 3600, 3900, and 4200. There are also special sizes like 3800 and 4000. The maximum length for ordinary slabs is 4200mm, and the widths are usually four-hole 400mm and five-hole 500mm.
• Live Load Capacity Ratings: For general residential use, Class I slabs can withstand a live load of 1KN/M², and Class II slabs can withstand a live load of 2KN/M². In the southwest region, the minimum requirement is Class IV slabs, which can withstand a live load of 4KN/M². These prefabricated slabs have high strength, meeting the load-bearing capacity requirements for house cover plates. They can effectively support the loads on the upper part of the house and ensure the safety and stability of the house structure.
