Almost all field and industries today use general steel as their primary material especially in building structures and inventing new devices. In fact, steel is considered the main material in the construction industry. Because of its outstanding properties, it is used often in every aspect of human life. The benefits of steel in the structural field are obviously well known. However, like other metals which have also numerous disadvantages, steel is no exemption and has disadvantages, as well.
The following are considered the disadvantages of using steel not just in structural design material but as well as other cases:
*The construction of a buildings structure that uses steel can cost more compared to using other types of materials especially if the steel used is are the types which undergo special furnishing process such as stainless steel.
*The strength of the steel reduces extensively when heated at a high temperature like in a fire. Furthermore, the heat will transfer in a very fast pace in the different part or portion of the steel. These will be one of the reasons why buildings need fireproofing.
*The maintenance of the general steel frames and other steel parts are needed especially if it is exposed from too much air and water. Frequent maintenance, then, becomes necessary with bridges and other structures that get direct exposure by these elements. These structures are subjected to corrosive elements, which makes it necessary to regularly paint it to protect from corrosive substantives. Applications like these will help reduce the risk of corrosion.
In summary, these disadvantages should be not taken granted and must be attended regularly to avoid accidents and failures.
