Metal constructions are widely used in various types of buildings and companies. The combination of the different main elements of the building (beams and columns) is integrated into a single whole and defines the structural form of the work.
The main metallic structure comprises Sa 387 Gr 11 that stabilizes and transfers the loads to the foundations (generally made of reinforced concrete). The main metallic structure is the one that ensures that it does not tip over, that it is resistant and that it does not deform.
The Metallic Structures are those in which most elements or parts that form them are made of metal (more than 80%), usually steel. A structure of this type can be called a Steel Structure.
Advantages of metal constructions
The main benefits of metal construction are:
Easy disassembly and exchange in steel constructions; Thanks to this, the elements of the work can be reinforced or replaced with greater ease and efficiency.
Tightness (prevents leaks and foreign particles from entering the structure’s interior, be it water, gases, air, dust, etc.) to gases and water, conditioned by the high density of steel.
Industrialization allows metal constructions to be made in workshop conditions, and their assembly is mechanized on the building site; all of the above accelerates the commissioning of the work.
The high load-bearing capacity of the material under various forms of stress state (traction, compression, bending, etc.), a capacity with relatively small dimensions of the cross sections of the elements, allows them to withstand considerable loads.
The reliability of construction work is due to the relatively high uniformity of the mechanical properties of steel.
Possibility of using the material from buildings that have already worked longer than expected in the service period.
The advantage of aluminium-based alloys lies in their low density (p=2700 kg/m3), while their mechanical strength and corrosion resistance are relatively high.

Structural steel is very flexible. It can be shaped into any shape without changing its properties. Depending on the design, it can be made into paper or wire. Is 2062 Grade B can withstand external stresses such as earthquakes, thunderstorms and hurricanes. A well-maintained steel structure can last up to 30 years if properly maintained.
Steel is malleable—high strength-to-weight ratio, which means high strength per mass unit. Therefore, unlike other building materials, the steel structure is small and light, regardless of the size of the entire structure. Steel is easy to manufacture and can be mass-produced. Sectional steel can be manufactured in an off-site workshop and assembled on-site. This saves time and increases efficiency throughout the construction process.
It is essential to paint its surfaces or resort to other protection methods. Structural Steel Plate Suppliers recommend the best construction material.The relatively low normal modulus of elasticity of said alloys (E=7100 KN/cm2) determines the high degree of deformation of said constructions; its low resistance to fire: at temperatures above 100ºC the mechanical properties of the alloy worsen, and at temperatures higher than 200ºC the dragging of the metal begins.
