What is a lightweight metal structure?
A light steel structure is a modern building system made of galvanized steel profiles, produced with precision in the factory and assembled on site. Due to their high earthquake resistance, quick assembly and excellent durability, light steel houses and buildings have become one of the most popular solutions for homes, offices and commercial spaces.
Asi Casa Design offers projects light steel houses and metal structures to the highest quality standards.
Advantages of Lightweight Metal Structures
1. Superior Earthquake Resistance
The lightweight metal system has an elastic structure that significantly reduces the effects of seismic movements, providing a safe and stable environment.
2. Fast Production and Efficient Assembly
The elements are manufactured to exact dimensions in the factory, and assembly on site is carried out in a much shorter time than in traditional construction.
3. High Durability and Maintenance-Free
Galvanized steel does not rust, rot, or get damaged by pests. Lightweight steel homes are durable and require minimal maintenance.
4. Excellent Thermal and Acoustic Insulation
With the right insulation materials, lightweight metal structures provide comfort in any season and contribute to long-term energy savings.
5. Light Weight and High Safety
The low weight of the structure reduces pressure on the foundation, making it an ideal choice even in areas with difficult soil.
6. Flexibility in Design and Modern Architecture
The system allows for customized projects for homes, offices or commercial spaces, offering total architectural freedom.
7. Ecological and Sustainable Solution
The steel is recyclable 100%, and the construction process generates very little waste, making it an environmentally friendly solution.
The Advantages of Asi Casa Design Light Steel Houses Compared to Other Types of Construction
Asi Casa Design light steel structure houses represent one of the most modern and efficient solutions on the market. Compared to traditional structures (concrete, brick or wood), light steel constructions offer numerous benefits in terms of safety, durability and speed of execution.
1. Lighter and stronger structure
Galvanized steel has a high load-bearing capacity and low weight. This combination provides excellent stability and reduces the load on the foundation.
2. Superior earthquake performance
Lightweight metal structures are flexible and better absorb seismic energy. This makes steel homes much safer in seismically hazardous areas.
3. Reduced production and assembly time
All elements are manufactured with precision in the workshop and arrive on site ready to assemble. Compared to concrete, the execution time is significantly shorter.
4. Excellent thermal and sound insulation
Our systems use mineral wool and basalt wool, offering a high level of energy efficiency. The houses are warm in winter and cool in summer, with low energy consumption.
5. Durable, crack-free walls
The metal structure does not change its shape over time, which eliminates the appearance of cracks specific to traditional masonry.
6. High fire safety
Materials such as Boardex, fiber cement and rock wool are classified A1 – non-combustible, providing additional fire protection.
7. Total architectural flexibility
The projects can easily adapt to any need. The partitioning, interior design and facade can be customized without structural limitations.
8. Long service life and corrosion resistance
Galvanized steel is protected against rust, and with minimal maintenance it can have a lifespan of 80–100 years.

LOAD-BEARING SYSTEM
The U-type load-bearing profiles, obtained by the Rollform machine from galvanized sheet metal, and the U-profiles used in the production of trusses form the main skeleton of the building.
To stiffen the structure and connect the trusses to each other, omega-type purlins, also produced by Rollform, are used.
PLAN
The determination of sections of metallic materials is carried out using the SAP2000 method.
Projects are drawn in AutoCAD and provided as manufacturing drawings.
The entire portal system is made up of special galvanized C and U profiles, obtained using the Rollform machine.
All calculations and architectural drawings are made by our technical staff using AutoCAD and SAP2000.
