Types & Variants of Steel Bars & their Uses

According to Maslow’s hierarchy of needs, once an individual's physiological desires have been fulfilled, the ultimate need for safety and security becomes his/her next top priority. To this effect, whenever an individual plans on constructing a building, his/her chief concern lies in the solidity, strength, and sturdiness of the building so as to allow for people to have a sense of security while being inside it. This specific task necessitates various important choices being made and tasks being performed during the construction process. Every such decision needs to be taken cautiously and with complete consideration and understanding based on the type of building one is intent on constructing. One such decision pertains to the diameter and quantity of reinforced steel bars to be used. Steel is a major component of construction since it is comparatively light on the pocket and is a known ‘green’ product given its recyclable nature. This being said, steel is not necessarily easy to install and use, but its intrinsic strength and toughness provide extra strength to the infrastructure. For this reason, structures constructed using steel are identified as durable and protected as compared to those without it. In particular, steel assists in protecting the building or house, to a considerable degree, against earthquakes, fires, and floods. Within steel, however, one has to consider the wide range of diameters that reinforced bars are very commonly produced in.

10 MM Steel Bars

The 10 MM Steel Bar, one of the types of Reinforcement Steel, is specifically designed to give strength to the concrete used in the building. It basically creates a form of reinforced concrete by significantly increasing the tensile strength of the concrete. As concrete and steel are known to have similar thermal expansive characteristics, they amalgamate to create a strong building that can withstand harsh weather conditions and strong forces. 10 MM Steel Bars are also long-lasting and prove to be highly effective in mitigating the likelihood of cracks. They are predominantly used in column footings and in roof slabs.

12 MM Steel Bars

The 12 MM Steel Bar is another type of Reinforcement Steel, similar to 10 MM Steel Bar, that is used in column footings so as to make them stronger. This, in turn, leads to increased safety of the structure by safeguarding it against sinking in the ground. Other than this, the 12 MM Steel Bars are used in grade beams, roofing beams, roof slabs, and staircase slabs.

16 MM, 20 MM & 22 MM Steel Bars

The 16 MM, 20 MM, and 22 MM Steel Bars are used mainly in beams and columns, depending upon the type of building and the needs of the structural design as these diameters provide numerous advantages and uses. They are used in the grade beams of the structure's columns to effectively connect them together, and in roofing beams to strengthen and support the walls above doors and windows without having to worry about the load compression thereof. They may, depending on the decision-maker's preference, also be used in staircase slabs since they create reinforced concrete and provide support to the structure of the stairs. Along with this, 16 MM, 20 MM, and 22 MM Steel Bars may also be used in the main beams to enhance their bonding with the columns and to preserve the structure of the building as per the envisaged design and expectations.

25 MM, 32 MM & 36 MM Steel Bars

The 25 MM, 32 MM and 36MM Steel Bars are commonly used in the beams, columns, foundations and slabs of larger buildings. Their thicker diameter provides the much-needed extra strength to carry much heavier loads, and maintain the structure's shape. Such diameters are often seen used in the construction of hydraulic structures, such as bridges and dams.

28 MM Steel Bars

The 28 MM Steel Bar is known to be particularly effective in guaranteeing durability, safety and strength for commercial endeavours, including, but not limited to, agricultural infrastructure, airports, fencing, and other similar structures.

40 MM Steel Bars

Despite the intrinsic potency of concrete, the 40 MM Steel Bar is used with concrete to ensure the building is able to withstand high force and tension. As concrete is susceptible to cracks caused by tensile force, the addition of a high tensile material, such as the 40 MM Steel Bar, provides a cost-effective and lasting solution. Moreover, for extremely complex and unique designs, 40 MM Steel Bars deliver the requisite strength, and prevent most types of deformities.

The wide range of options, in terms of diameters, may overwhelm any layperson. However, their classifications and uses are fairly straightforward, especially for seasoned architects and contractors, who are able to instantly assess the needs against the design's requirements. Nonetheless, double-checking what steel is being used and where not only enhances one's confidence in one's project, but is able to assist in balancing financial outlays against the requisite strength of the structure.
