Due to the increase in demand for prefabricated houses, many unprofessional manufacturers and intermediaries have entered the industry, and many products of uneven quality have appeared on the market. This also brings certain risks to consumers when purchasing prefabricated houses. To ensure the reliable quality of the prefabricated houses purchased, we need to pay attention to the following points when ordering:


1. Choose a manufacturer with strength, scale, and reputation: choosing a reputable manufacturer can guarantee product quality and after-sales service; a large-scale factory means that the product is more mature, and basically, there will be no quality problems. You can learn about it through the manufacturer's official website, e-commerce platform, and other channels.


2. Understand the material and process of the product: It is necessary to understand the material. Poor materials will affect the performance and service life of the prefabricated house, so try to choose high-quality materials when ordering.


3. Check factory qualification and project experience: Since the prefabricated house industry has a certain threshold, we need to check whether the company has obtained a professional production qualification certificate before placing an order, and we can check the project cases that the factory has done in the past to judge whether the factory is trustworthy.

Because prefabricated houses are often used for earthquake relief, prefabricated houses are required to have a certain earthquake and wind resistance. Whether it can have a good earthquake and wind resistance depends on two aspects.


First, the structural design of the prefabricated house itself and the selection of materials. The main frame of the prefabricated house produced by Zhongnan Steel Structure Co., Ltd. is made of special steel, and high-strength bolts connect the structure; the wall panels are made of color steel composite board thickness 75mm, core insulation material glass wool, bulk density ≥ 2.0KN/m³, combustion performance is Class A non-combustible, board surface is 0.35mm thick color steel plate, double-sided film, edge sealing around, strong heat insulation, sound insulation, and fire resistance. The combined house is an integral structure, and high-strength bolts connect the modules. It is durable and has strong deformation resistance.


Second, whether the prefabricated house has good seismic and wind resistance performance also depends on the construction of the on-site workers. Workers need to strictly follow the relevant standards during installation to ensure the safety and stability of the structure. Therefore, it is necessary to choose an experienced manufacturer for cooperation so that there will be technical engineers to guide the whole construction process. Make sure that the prefabricated house can be installed correctly and safely.


I hope this article can help you and let you choose the right prefabricated house manufacturer for cooperation.
