What’s Better For Structures, Metal Or Concrete
If you are planning to construct a structure, there are many things you have to think about; one of them is the material you will use for the structure of your building. Most times, it is the builder that will make the decision. But the homeowner may also have inputs.
The decision on the structural frame is usually between concrete and metal. When it is concrete, it is generally reinforced concrete that is used. Both have their pros and cons in terms of durability and cost.
The material used will also affect the building design, and performance is another key factor in making the decision. Here, we look at some of the factors to consider when making such decisions.
Costs
The cost of material and construction is always something that must be considered. For this, metal is a much cheaper choice. It takes a lower proportion of the construction work. Concrete, especially when reinforced, is also more expensive than metal.
However, concrete can be cost-effective in the long run when you consider the cost of maintenance and other post-construction costs.
Availability
One of the factors that have affected the price of concrete is the unavailability of materials needed to make it, especially cement. The cost of cement continues to increase consistently as the cost of transporting raw materials increases.
However, this availability problem does not affect metal that much, and the supply remains reliable and consistent.
Speed
The time frame for construction is longer for steel when compared with concrete. Concrete structures can be constructed within a faster period of time, and the only delay would usually be in how long it takes for it to cure.
Strength and Durability
In this area, concrete is a better option based on wider industry opinion. It is more durable and resistant to fire, potential attacks, and environmental disasters.
In a fire, metal might melt if the heat should reach a certain level. Although it can be strengthened further with flame retardant and fire insulation coatings, it still doesn’t compare with concrete.
Extreme cold can equally affect metal structures, including their temperature after construction. Therefore, it is usually necessary to apply coatings.
However, when it comes to keeping the structure standing firm, metal is the best. It is why concrete is reinforced with steel so it can serve its purpose effectively. The compressive strength of concrete is also much higher than that of steel.
Flexibility
Concrete is also known to be very versatile. In fact, it can be molded into practically anything, thereby allowing for creative designs. Of course, steel is equally versatile, which is why it is heavily used for commercial buildings.
Conclusion
Both materials have their positives and negatives, which is why it takes an experienced builder to make the right choice in each case.
