| Seeking for a solution to your construction employee's official request?How about considering modular house? For any construction enterprise,it is a common thing to deploy the installation workers to local construction site to fulfill their duties.However,the worker's safety and well-being must come first at any circumstances which is foundamentally provide them satified accommodation,catering and leasurement options at spare time.On the other hand,considering the high requirements of mobility and easy-to-assemble for the auxiliary house/building.modular house is definitely a reliable choice. You may wonder what is exactly the define of a modular house system.To start with,Modular House is a term used to describe the use of factory-produced pre-engineered building units that are delivered to site in Modules. The modular units may form complete rooms, or parts of rooms. Modular houses are generally made into six sided boxes constructed in a factory, then delivered to site and using a crane, the modules are set onto the building's foundation and joined together to make a single building. The modules can be placed side-by-side, end-to-end, or stacked, allowing a wide variety of configurations and styles in the building layout. GeneralThe modular unit or container is designed as a light solid construction consisting of floor and roof frames and corner profiles. The system enables compounding of individual containers in longitudinal and transverse directions without limits. It also enables compounding of containers in 2 floors in height (ground floor + first floor), or in 3 floors in height for warehousing of these containers (ground floor + 2 floor). Wainscots of the container are made of light insulation panels and offer pleasant climate in the interior due to their building and physical properties.Dimensions and Tare (ISO Standard 1161)

I.Steel plate cutting
The H section steel plate should be checked again by the factory and shall be applied under the condition of up to design and specified requirements after checking. Steel plate cutting should be aimed at quality guarantee and material saving. For each process like plate cutting,H type assembly, components assembly and pre-assembly should be carried out by profession setting-out worker precisely on processing surface and assembly sample plates.To guarantee the accuracy of the components'geometrical dimension,tolerance of form and position, angle and contact surface,inspection is necessary by inspector after setting out.In order to ensure the cutting quality,the surface of the ultra-thick plate is subjected to the surface carburizing hardness test before cutting.The CNC cutting equipment is preferred for cutting.The high purity 98.0% acrylic gas and 99.99% liquid oxygen gas are used to guarantee the smoothness and flatness of the cutting surface without notches and slags.The groove is cut by a special imported cutting machine.
