What does CMMA mean in CONSTRUCTION

What Does CMMA Stand For?

As mentioned previously in the introduction, CMMA stands for Corrugated Metal - Metal Arch. This style of bridge consists of two or more curved sheets of metal forming an arch over a span. The metal used is usually steel, although other types such as aluminum can also be used depending on the application. This type of bridge has been used since ancient Roman times due to its proven durability, load bearing capacity and versatility to span large distances with relative ease.

Advantages Of Using CMMA

The primary advantage of using this method for construction is its strength and durability. Corrugated metal arches are extremely strong and can stand up to significant loads even when compared to traditional construction methods like masonry or wood structures. They are also much easier and cheaper to construct than many other types of bridges since they do not require complex support frameworks or reinforcements like concrete arches do. Furthermore, they can be readily adapted to various terrain conditions allowing them to be installed in less hospitable locations where other alternatives would be unsuitable or too expensive.

Disadvantages Of Using CMMA

The primary disadvantage of using corrugated metal arches is their aesthetic quality which can be lacking compared with other types of bridges such as concrete or stone ones; however, this does not detract from their usefulness in many practical applications where looks may not be important considerations during the design process. Additionally, there is also some potential risk associated with this type of structure as its load bearing capacity may become compromised if corrosion sets in due to inclement weather conditions over time.
