Double Layer Prefab Steel Frame House Construction

A Double layer prefab steel frame house construction is a two-story building constructed using hot-rolled or cold-formed thin-walled steel as the main load-bearing framework. The components are produced in a factory and then transported to the site for bolted or welded assembly. It does not belong to the traditional "brick-concrete" or "reinforced concrete" structure; instead, it is a typical prefabricated building. EIHE Steel Structure is a Chinese steel structure building supplier and manufacturer established in 2005.

Different structural systems

● Heavy steel frame structure

Using H-shaped steel or square tube columns, similar to a reduced version of large factories or high-rise office buildings. The beams and columns are rigidly connected, with strong bearing capacity, suitable for large-span spaces. The second floor floor slabs usually adopt profiled steel plates combined with cast-in-place concrete.

● Light steel keel structure

Using 1.0mm - 3.0mm thick galvanized cold-formed thin-walled steel, arranged densely like building blocks. The walls themselves are load-bearing components, with extremely light self-weight and excellent seismic performance. It is mostly used for residential and guesthouse buildings.

Prefabrication process

● Design digitization

First, precisely model all components in the BIM software to generate a cutting list for all components.

● Factory precision processing

Steel is cut, drilled, and welded in the workshop. The door frames, water and electricity pipeline reserved grooves are all pre-installed in the factory. The internal part of the wall is filled with insulation and soundproofing cotton, and the outer layer is encapsulated with structural panels to form a prefabricated wall unit.

● On-site dry work

There is no need to mix cement on-site. Just connect the prefabricated beams, columns, wall panels, and floor slabs like assembling a car using high-strength bolts. For a 200-square-meter Double layer prefab steel frame house construction, the main structure can usually be topped out in 3-5 days, reducing the construction period by approximately 60% compared to traditional brick-and-concrete construction.

Parameter (Specification)

Product case

The Taishan Station in Antarctica

● Project Overview

The research station built by China in the interior ice sheet of Antarctica is mainly a Double layer prefab steel frame house construction.

● Characteristics

It represents the ultimate "extremely cold and high precision" limit of steel structure prefabrication. All components are pre-assembled in China and then disassembled and transported. On-site, an "overhead" structure is adopted to prevent snow from burying during winter. This case shows you that when no concrete pouring is allowed on-site (at -40℃ in Antarctica), the fully bolted connected prefabricated steel structure is the only feasible solution.

FAQ

1. How long can this Double layer prefab steel frame house construction be used?

It is a permanent building. The design service life of the main structure is 50 years, and in actual high-quality projects, it can last for over 70 years with anti-corrosion maintenance.

2. How long is the project duration?

The overall delivery cycle is 40-70 days.

3. I want to build a living room with large floor-to-ceiling windows. Is the structure allowed?

Absolutely. The heavy steel frame structure can achieve a large-span space of 6-8 meters without internal columns; the light steel system can also achieve a local large space by adding truss beams.
