Modular Worker Dormitories

Home » Product » Modular Worker Dormitories

Introduction

Modular worker dormitories are temporary accommodations that are prefabricated in factories, transported to construction sites, and quickly assembled. They are characterized by flexible expansion and easy disassembly and relocation. Typically, they integrate basic living facilities such as water, electricity, and sanitation, effectively meeting the centralized accommodation needs of the construction and engineering industries.

Wanzhi Steel modular worker dormitories use standard shipping containers as basic modules, and a single dormitory unit can be assembled on-site within 2 hours, providing a complete product from basic accommodation units to a complete living community.
