ES One of the most common questions when someone faces the exciting challenge of building their home is: What materials are used to build a house? and it is completely valid.
Choosing the right materials not only defines the aesthetics of the house, but also its safety, durability and efficiency. At Aceros MAPA, with more than 80 years in the steel industry, we have been part of thousands of housing projects throughout the country, and we know that a good house starts with a good base of materials.
Today we want to share with you, from our experience, which are the most used materials to build a house, and why steel is one of the most intelligent and sustainable.
1. Solid foundations: concrete and steel
All construction starts at the bottom. The foundation is the base of everything and must be extremely resistant. The most common is to use reinforced concrete mixes, where steel plays a leading role.
 We provide the rods, beams and profiles that reinforce these structures to guarantee stability and resistance over time.
 At Aceros MAPA we understand that the quality of the steel at this stage defines the useful life of the house. That is why our products are certified and designed to withstand heavy loads without deforming or deteriorating over the years.
2. Walls: brick, block and metal structures
Traditionally, concrete blocks, ceramic bricks or prefabricated panels are used for walls. But more and more builders are opting for industrialized systems, where structural steel is the protagonist due to its ease of installation and seismic performance.
We offer metal profiles and light structure solutions that make the execution of the walls faster and safer, without losing strength. In addition, this type of materials allows for cleaner construction, less waste and shorter construction times.
3. Roofs and ceilings
The roof is one of the most visible and exposed parts of any house. Therefore, materials must offer weather protection, thermal insulation and structural strength.
 Sheet metal is an ideal choice because of its durability, economy and variety of finishes.
 At Aceros MAPA we offer galvanized, pre-painted and tile-type sheets that adapt to all types of architectural design, from the most traditional to the most contemporary.
4. Floors and structural reinforcements
In the construction of floors and mezzanines, concrete is still the most common material used as a base, but to guarantee its strength and stability, reliable structural elements are required.
At Aceros MAPA we contribute to this stage with corrugated rods and structural profiles, ideal for reinforcing concrete slabs and providing support in mezzanine floors, especially in multilevel constructions. These elements help to better distribute loads, avoiding deformations and increasing the useful life of the structure.
5. Electrical, hydraulic and gas installations
Although they are not visible materials, they are essential. Steel is also present here: structural steel pipes are often used to house cables or reinforce ducts. And if metal structures are used to support the roof, the design of the installations becomes easier and more efficient.
Why choose steel to build your house?
Because it is strong, durable, versatile and environmentally friendly. At Aceros MAPA we have been witnessing the transforming power of steel in construction for more than eight decades. With us you get:
- Proven quality, with certified products.
- Technical assistance at each stage of the project.
- Timely delivery and national coverage.
- Constant innovation to adapt to new ways of building.
When you ask yourself what materials are used to build a house, think long-term
Think safety, efficiency and sustainability. And that's where steel stands out. From the foundation to the roof, its presence ensures stronger, lighter and more environmentally responsible structures.
 At Aceros MAPA, we are ready to accompany you in that great life project that is building your home. Because more than just selling you steel, we want to help you build your future.
