Differences Between Container Buildings and Reinforced Concrete Houses — Our Company
There are many differences between container buildings and reinforced-concrete houses. On energy performance, container buildings use composite insulated walls with low thermal conductivity, so interiors stay warm in winter and cool in summer. The insulation of a 100 mm composite wall is comparable to a traditional brick-and-concrete wall about 610 mm thick. Conventional steel-structure buildings, by contrast, conduct heat more readily, offer only average insulation, and consume more energy. Construction cycles for container buildings are short: about 10–20 days for a single unit and 20–40 days for a combined layout before handover, with fewer limits from natural conditions.
A frame structure typically means the building relies on reinforced-concrete beams, slabs, and columns for load bearing, while walls are infill materials (such as hollow blocks) that do not carry structural load and mainly provide enclosure and sound insulation. Many high-rise buildings use this approach today.
A steel frame structure is built mainly from steel and is one of the primary building-structure types. Its traits include relatively light self-weight, high reliability in service, good resistance to vibration (earthquake) and impact, a high degree of industrialization, and ease of forming sealed assemblies—along with drawbacks such as corrosion risk and weaker fire resistance.
A reinforced-concrete structure means reinforced-concrete beams, slabs, columns, and walls share the load together.
Reinforced concrete is a structure built with steel bars and concrete: the steel takes tension and the concrete takes compression. Strengths include durability, good fire performance, lower steel use than pure steel structures, and relatively low cost. Because steel has good plasticity and toughness, it can undergo larger deformation and handle dynamic loads well; steel is also highly homogeneous and isotropic and behaves like an ideal elastic body that matches basic assumptions in engineering mechanics. For that reason, steel structures generally outperform reinforced-concrete structures in seismic performance.
Container buildings have wide uses and varied types and shapes; they can be combined into almost any geometric form, including public buildings, family homes, and mixed-use projects. They are durable, made of high-strength steel, and offer strong resistance to earthquakes, compression, and deformation, with good sealing. Strictly manufactured movable buildings also have excellent watertightness.
Container buildings rest on an integrated box-type steel structure. Through splicing and assembly they support rich combinations, can be moved as a whole, and are easy to dismantle—well suited to buildings with a limited service life. For upgrades, new box units can be used and the project rebuilt elsewhere. Materials are mainly steel and formwork steel, and after retirement they can be recycled.
Containers include: dry-cargo containers, commonly 20 ft and 40 ft, usually fully enclosed with a door at one end or on a side; open-top containers without a rigid roof; flat-rack and platform containers, whose main traits are a thicker base to keep longitudinal strength—base strength exceeds that of ordinary containers, while interior height is lower; and ventilated containers, which generally have vents in the side or end walls, suited to cargo that needs ventilation rather than refrigeration and protection from moisture, such as fruit and vegetables. With vents closed, they can serve as general-cargo containers.
Other container types include tank containers, animal containers, refrigerated containers, bulk containers, and car containers. By material, widely used classes are: steel containers—high strength, firm structure, good sealing and watertightness, lower cost, easy to repair, and hard to damage, with main drawbacks of high self-weight and weaker corrosion resistance; aluminum containers—light weight, rust-resistant, attractive finish, good elasticity, and resistance to deformation, with main drawbacks of higher cost and easier damage on impact; and stainless-steel containers—high strength, rust-free, and strong corrosion resistance, with the drawback of large investment.
FRP (fiberglass-reinforced plastic) containers mainly offer good thermal insulation, corrosion resistance, and chemical resistance, high strength and durability under larger stresses, easy cleaning and simple repair, and relatively large internal volume; main drawbacks are higher self-weight and higher cost.
