Prefabricated Homes with High Quality and Durability

EIHE STEEL STRUCTURE is a reliable supplier of prefabricated homes, they are buildings with steel as the main structure. Their most prominent core feature is the adoption of prefabrication and assembly mode. All core components are produced and manufactured in factories. At the construction site, only the foundation needs to be laid and then directly installed. The main structure of the building is composed of steel beams and steel columns connected to each other, and the connection points between them are joined by bolts or welding. Prefabricated homes not only have a fast construction speed, but also are safe and stable with a long service life. The design flexibility of their structure can be easily expanded or disassembled. It has achieved the industrialization and standardization of architecture. Nowadays, prefabricated home buildings are becoming increasingly popular among residents.

What are Prefabricated Homes?

Prefabricated homes are representative of steel structure residential buildings. Compared with traditional concrete structure buildings, they are not only strong and durable but also recyclable and reusable, reducing construction waste. He revolutionized the traditional wet operation mode of pouring concrete on site. All components are produced and manufactured in the factory, significantly reducing dust pollution at the construction site. The modular production method in the factory can ensure consistent quality and precision of components. The batch production on the workshop production line can also shorten the construction period and enable the house to be put into use quickly. Prefabricated homes are becoming increasingly popular in modern residential construction and are widely applied in various fields, including villas, suburban houses, vacation homes, apartments and temporary housing buildings, etc.

Product Types

From the perspective of the main structure of the house, prefabricated homes are usually classified into light steel structure, heavy steel structure and modular steel structure.

The main materials of light steel structure are C-shaped steel and U-shaped steel, which are light in weight and low in thickness. The prefabricated homes of this structure have high cost performance, fast construction speed and less pressure on the foundation. It is usually applied to low-rise villas, suburban residences, etc.

The main material of heavy steel structures is H-shaped steel, which is heavier and thicker, used as steel beams and columns. Such prefabricated home buildings are often more solid and durable, have better seismic performance, and can withstand greater loads. It is usually applied to multi-story and high-rise residential buildings and apartments.

Modular prefabricated structures can be made of either light steel or heavy steel as the framework for each "box". It produces the entire room or space unit as a complete "three-dimensional module" in the factory and then transports it to the site for direct hoisting. It is usually applied to buildings with relatively uniform floor plans such as student apartments and staff dormitories.

Building Components

A complete prefabricated steel structure building is usually composed of the main structure system, the enclosure system, the equipment and pipeline system, and the floor system.

The main structure of the building is formed by the interconnection and welding of steel beams and steel columns to create the load-bearing structure of the building. The engineering team will select appropriate steel beams and steel columns, including H-beams, C-beams, etc., based on the size of the building structure, the construction area environment and the customer's requirements.

To achieve the effect of thermal insulation and heat preservation, the walls in the building's enclosure system are usually made of ALC panels, metal sandwich panels or concrete sandwich panels. Most roofs are made of metal shingles and asphalt shingles. These materials not only exert less pressure on the structure but also have high water resistance.

The materials of equipment and pipelines are no different from those of traditional buildings, such as PPR water supply pipes, PVC drainage pipes, copper core wires, PVC electrical conduits, etc. The pipelines are pre-embedded in the wall panels in advance when they are prefabricated in the factory, and there is no need to pre-embed them on site.

The floor system usually adopts reinforced truss concrete composite slabs, which is currently the most mainstream and best-experienced system for residential buildings. Its lower layer is a prefabricated concrete thin plate. After on-site installation, a layer of cast-in-place concrete is poured on the upper layer to combine with the truss as a whole. It has good integrity, high rigidity and sound insulation effect close to that of traditional buildings.

Main Advantages

Prefabricated homes are built quickly and have a short construction period. Factory production and on-site foundation construction can be carried out simultaneously, and the on-site installation efficiency is extremely high, saving about 30% to 50% of the time compared with traditional buildings.

Reliable quality and high precision. The components are produced in a standardized manner in the factory, with a controllable environment, stable quality and precise dimensions, thus avoiding errors caused by on-site manual operations.

Green and environmentally friendly, conserving resources. On-site operations mainly rely on dry methods, significantly reducing noise, dust and construction waste. Steel is a recyclable material, which conforms to the concept of sustainable development. Save water and save formwork wood.

It has excellent safety performance, especially in terms of earthquake resistance. Steel has high strength, light weight and good toughness, and can effectively absorb seismic energy. It is recognized as one of the structural forms with the best seismic performance.

The spatial layout is flexible. Steel structures can achieve greater spans, have fewer indoor load-bearing walls, and allow for flexible space division to meet personalized demands.

High space utilization. The walls are usually thinner than traditional brick or concrete walls, which can effectively increase the usable area indoors.
