When customers contact Suzhou Dongji House, many have already spent months researching the prefab housing market. This project from Sonora, Mexico, is a perfect example.
The customer planned to use the house as a residential home in Sonora, where summer temperatures regularly reach 36°C (97°F). Before contacting us, he had compared multiple local prefab housing suppliers and construction companies across Mexico.
After extensive research, he realized that although demand for modern prefab homes is growing rapidly in Mexico, many suppliers could not provide the insulation performance, anti-corrosion treatment, or customization options he required.
His goal was simple:
Build a comfortable, durable, energy-efficient prefab home that could withstand the local climate while serving as a model for future opportunities in the Mexican market.
He believes demand for high-quality prefab housing in Mexico will continue to increase, especially among families looking for faster construction and lower building costs.

Sonora experiences extremely hot summers, with daytime temperatures often reaching 36°C or even higher.
The customer wanted a prefab house that would remain comfortable indoors without excessive dependence on air conditioning.
After discussing the local climate, our engineering team recommended upgrading both the roof and floor with polyurethane insulation, creating a complete thermal envelope for the building.
Unlike standard insulation solutions, polyurethane provides outstanding thermal resistance, helping reduce heat transfer throughout the entire structure.
The polyurethane insulated wall system offers several important advantages:
For customers building prefab homes in regions with high summer temperatures, polyurethane insulation is one of the most effective solutions for improving energy efficiency and indoor comfort.
Another important topic during our discussions was corrosion resistance.
Because the customer expected the house to perform reliably for many years, he was not satisfied with ordinary painted steel.
Instead, we upgraded the steel frame with fluorocarbon (PVDF) coating, which offers significantly better durability than conventional paint.

Compared with standard coatings, fluorocarbon paint provides:
For projects located in regions with strong sunlight and changing weather conditions, fluorocarbon coating greatly improves the long-term durability of steel structures.
One reason the customer ultimately chose Suzhou Dongji House was our ability to customize every aspect of the project.
Rather than offering only standard models, we worked closely with him to optimize the house according to local climate conditions, insulation requirements, material preferences, and future plans.
Every project is designed around the customer's actual application rather than a one-size-fits-all solution.
