Industrial Mobile House Two Story Workshop Sandwich Panel
Fabricated H Beam Building Construction Light Warehouse Frame
Prefab Steel Structure for Commercial
Project Case: A 12 × 16-meter steel frame structure in Australia,
built on the basis of recycled containers.
| Primary Structure – The Robust Skeleton |
| Main Steel Frame (H-Beams) | H-shaped steel sections are used for the main beams and columns.
H-beams offer high bending strength and an economical
cross-section, serving as the core load-bearing components of the
structure. |
| Corrosion Protection | All primary steel members are treated with "red lead primer" as the
base coat and "mild-grey alkyd paint" as the topcoat, providing
excellent rust resistance and durability to ensure the longevity of
the main structure. |
| Enclosure and Secondary Structure – The Lightweight Skin |
| Roof and Wall System | Cladding | 0.5mm thick AZ150 aluzinc corrugated sheets are used. This material
offers outstanding corrosion resistance, heat resistance, and
service life, making it an ideal choice for industrial buildings. |
| Insulation | 75mm thick glass wool is installed to effectively reduce heat
transfer, maintaining a comfortable interior temperature year-round
and lowering energy consumption. |
| Purlins | Galvanized C150×1.8mm C-purlins are used for their lightweight and
anti-corrosion properties, providing support for the roof and wall
panels. |
| Container Units | 20-foot containers | which can be repurposed as offices, equipment rooms, storage areas,
or lounges, offering flexible usage. |
| Connections and Stabilization System – The Strong Joints |
| Foundation Connection | M24×850mm anchor bolts are used to securely fasten the steel
columns to the concrete foundation, resisting wind loads and
seismic forces. |
| Joint Connections | High-Strength Bolts | Critical load-bearing joints in the primary structure use Grade
10.9S M20 and Grade 8.8S M16 high-strength bolts, providing
exceptional connection strength and shear resistance. |
| Standard Bolts | Secondary structural connections use Grade 4.8S M12 bolts for
general fastening requirements. |
| Stabilization System | Wall and roof bracing systems, along with Φ12 round steel tie rods,
act as the "ligaments" of the structure, forming a spatially stable
system that effectively resists lateral forces and prevents
deformation. |
| Detailing and Finishing – The Refined Touch |
| 1. All trims, flashings, and ridge caps are color-matched to the
roof sheeting, ensuring a unified and aesthetically pleasing
appearance. |
| 2. Specialized screws, rivets, silicone sealants, and other
accessories are used to guarantee the weathertight integrity of the
roof and walls, preventing water leakage. |
| 3. Φ110 downpipes are installed to complete the building’s drainage
system. |
This building exemplifies innovative reuse, fusing a new structural
steel expansion with a functional base made from recycled shipping
containers.
Key Project Advantages
Creativity & Distinctiveness
The innovative use of shipping containers creates a unique
architectural identity, offering strong visual memorability and
conversation value.
Structural Efficiency & Cost-Effectiveness
The steel structure enables rapid construction and prefabrication,
shortening project timelines. Container reuse significantly reduces
overall costs.
Clear Functional Zoning
The layout—with containers at four corners and a soaring central
space—achieves optimal "quiet-active" and "private-open"
separation, supporting diverse functions without interference.
Durability & Longevity
From high-strength bolts to multi-layer corrosion protection, and
from robust bracing systems to high-quality cladding, the design
ensures extended service life with minimal maintenance.
Eco-Friendliness & Energy Efficiency
Container reuse demonstrates sustainable construction practices.
Coupled with 75mm glass wool insulation, the building delivers
outstanding energy conservation performance.
Key Advantages of Steel Structures
✅ High Strength & Durability
- - Steel has an excellent strength-to-weight ratio, allowing for
large spans and heavy loads.
- - Resistant to earthquakes, winds, and extreme weather when
properly designed.
✅ Faster Construction
- - Prefabricated components enable quick assembly, reducing project
timelines by 30-50%.
- - Less on-site labor required compared to concrete structures.
✅ Cost-Effective
- - Lower foundation costs due to lightweight nature.
- - Reduced construction time = **lower labor & financing costs**.
✅ Design Flexibility
- - Allows long spans (100+ meters) without columns, ideal for open
spaces.
- - Can be easily expanded or modified in the future.
✅ Eco-Friendly & Sustainable
- - Steel is 100% recyclable, reducing construction waste.
- - Energy-efficient designs can incorporate solar panels and
insulation.
✅ Low Maintenance
- - Galvanized or painted steel resists corrosion and rust.
- - No termite or mold damage, unlike wood structures.
