Double wing expansion box is a flexible and movable residential or commercial space that can play its unique advantages in various fields such as construction sites, temporary residences, school classrooms, training centers, cafes, restaurants, retail stores, medical clinics, art workshops, music recording studios, resorts, etc.
Not only suitable for short-term temporary accommodation needs, such as natural disaster relief, but also for long-term residence, such as tourist camps, small communities, etc.
This flexibility can be customized and personalized according to needs, meeting the needs of different time lengths and providing flexible and mobile residential or commercial space solutions for various fields.

Double wing expansion box house is a mobile house that can be expanded and contracted. Adopting innovative design concepts to transform traditional living.Upgrade and renovate the moving house. By using a double wing folding mechanism, the house presents a complete living experience when unfolded. Space, when folded, becomes a compact and easy to move device. This design concept not only endows .The activity room provides more flexibility and offers more possibilities for people’s living space.

Expansion box is a new type of item that looks like both a box and a handbag, not only exuding a fashionable atmosphere in appearance, but also providing convenience for daily life. It is made of environmentally friendly materials, lightweight and sturdy, suitable for carrying. The internal design of the expansion box is reasonable and can meet different needs, such as storing files, books, laptops, etc., making daily work easier. At the same time, it can also be used as a travel suitcase, with a high pull rod design for easy walking, and multiple functions such as waterproofing and scratch resistance to protect property safety. There are also various styles of expansion boxes with unique features to choose from, meeting the aesthetic needs of different groups of people.

Double wing expansion house, also known as double wing folding house, uses galvanized high-strength square tube, galvanized angle iron and other light steel materials as the frame, anti-corrosion double-sided color steel composite board as the wall, and high-strength hinges to connect the frames. After scientific calculation, it can quickly expand the space of the house. The expanded house space is nearly three times larger than before expansion.

The quality of light steel villa houses is very good. It is a new type of villa that is built using a steel frame structure like a building block game for children. Although the entire construction process is simple, it is higher than traditional villas in some aspects. This light steel villa has excellent quality and features such as durability and wind resistance. Durability, long service life, thermal insulation, and keeping the room warm in the cold winter.

The core material of light steel villa houses is the light steel main keel generated by hot-dip galvanized steel plate through cold tying technology. Through precise calculation and the support and fusion of auxiliary components, it has a scientifically reasonable bearing capacity to replace traditional houses. Compared with concrete structure housing, the construction steel of light steel villas can be reused, while the concrete cannot be reused; Concrete causes environmental effects and is not beneficial to health, but light steel construction does not require concrete at all, so there is no such situation.

Steel structure factories must undergo regular cleaning and maintenance, usually at least once a year for routine inspections to identify potential issues.
If there is any damage to the surface of the metal plate in the steel structure factory building, it should be repaired in a timely manner to prevent corrosion of the metal plate surface by sunlight and rain. If necessary, all paint should be applied to protect the metal roof panels and provide effective insulation and waterproofing, saving indoor air conditioning energy.

The cleaning of the exterior walls of steel structure factories largely depends on the environment. When cleaning the surface, be careful not to scratch, avoid using cleaning products containing bleach or abrasives, steel wire balls, and wear-resistant products. Rinse with clean water from top to bottom.Branches, leaves, and other similar objects should be cleaned in a timely manner, especially the roof, otherwise it is easy to block the drainage outlet and cause water leakage.

Steel structure protection includes fire prevention, anti-corrosion, and rust prevention. Generally, anti-corrosion treatment is not required after fireproof coating treatment, but anti-corrosion treatment is still required in buildings with corrosive gases. There are many types of fireproof coatings in China, such as TN series, MC-10, etc. Among them, MC-10 fireproof coatings include alkyd enamel, chlorinated rubber paint, fluororubber coating, and chlorosulfonated coating. Suitable coatings and coating thicknesses should be selected during construction according to the steel structure type, fire resistance rating requirements, and environmental requirements.

Steel structure engineering involves a wide range of aspects and is technically difficult. In its promotion and application, it must comply with national and industry standards and specifications. The administrative departments in charge of construction in various regions should attach importance to the professionalization stage of steel structure engineering, organize training for quality inspection teams, and timely summarize work practices and new technology applications. Colleges, design departments, and construction enterprises should accelerate the training of steel structure engineering technicians and promote mature steel structure CAD technology.
