JQHSG focuses on modular housing and has developed a variety of container houses suitable for large-scale engineering camp construction projects. After investigating the performance of dozens of steel materials, JQHSG ultimately determined that Q235B steel is the most suitable for building modular housing. Meanwhile, the steel surface must undergo full hot-dip galvanization, followed by an electrostatic powder adsorption and baking process, to extend the product's service life in harsh environments. Verified by structural testing and calculations, our products have a service life of over 30 years. Currently, some users have used JQHSG's container houses for up to 15 years without any structural issues
