Gansu Prefabricated House Customization

Customization of prefabricated houses in Gansu requires targeted control of key aspects based on specific types (such as prefabricated composite floor slabs or integrated houses) to ensure quality, efficiency, and cost control.

Key Points for Customizing Prefabricated Composite Floor Slabs

1. Accurately Align with Project Requirements
   • Strictly determine floor slab dimensions according to architectural drawings, focusing on span, thickness, and the positions of embedded parts. Errors must be controlled within millimeters to avoid affecting structural stability.
   • Plan the treatment of joint seams in advance and clarify with the manufacturer whether to reserve waterproof tongues or grout holes. For example, waterproof tongues can effectively prevent leakage in wet areas like bathrooms; grout holes can enhance the load-bearing performance of joints in large-span spaces.
2. Strictly Screen Production Manufacturers
   • Give priority to local manufacturers in Gansu that hold the "Prefabricated Concrete Component Production License" and verify their recent project cases to ensure technical maturity.
   • If the project has environmental requirements, request the manufacturer to provide green production certificates. For example, using steam curing technology instead of natural curing can shorten the curing cycle and reduce carbon emissions.
3. Optimize Transportation and Installation Processes
   • For projects in mountainous areas of Gansu with complex terrain, choose shock-resistant transportation vehicles and reinforce the fixing devices for components to prevent cracking during transportation.
   • During the installation phase, require on-site guidance from the manufacturer's technical personnel, focusing on controlling the lifting sequence (such as lifting symmetrically from the middle to both sides) and the setting of temporary supports (the spacing between support points should generally not exceed 1.5 meters) to prevent deformation of the composite slabs due to uneven force distribution.

Key Points for Customizing Integrated Houses

1. Evaluate the Enterprise's Integrated Capabilities
   • Give priority to enterprises that offer full-chain services including design, production, and installation to avoid rework caused by the disconnection between design and construction. For example, Ningxia Yinhengfa Steel Structure Engineering Co., Ltd. reduces communication costs and shortens the construction period through a "source factory + full industrial chain closed-loop" model.
2. Focus on Localized Service Advantages
   • For projects in the five northwestern provinces with large geographical spans, choose service providers with manufacturing bases and warehouses in Gansu to reduce transportation costs (such as reducing freight by 10%-20% by shortening the transportation distance) and shorten maintenance response times (generally controllable within 24 hours).
