Plain Rebar
Steel reinforcement bars (plain rebars) are among the most critical components used in any construction project. Without them, structural operations in any building project would come to a halt. One of the primary reasons for the widespread use of rebar in construction is to compensate for the low tensile strength of concrete.
Naturally, producing reinforced concrete is not the sole application of steel rebar. Depending on the manufacturing standard, rebar is categorized as either deformed or plain (smooth) rebar, among other classifications. The price of rebar varies accordingly. In this article, we will examine the price of plain rebar and how to purchase it.

Plain Rebar Weight
There are three primary methods to calculate or determine the weight of plain rebar:
-
Online Rebar Weight Calculators
Websites such as Shahin Felez Sepahan offer tools where you can enter the diameter and length of the rebar to calculate its weight easily. -
Weight Calculation Formula
You can also use the following formula to calculate the weight manually:
Weight = (Diameter × 3.14 × Length × 7.8) ÷ 1000 -

Applications of Plain Rebar
The only difference between plain and deformed rebar lies in the presence or absence of surface ribs (deformations). This seemingly simple variation leads to significant differences in their performance in structural applications.
For example, deformed rebar is commonly used in foundations due to its enhanced bonding with concrete, which significantly increases structural integrity. On the other hand, plain rebar lacks such mechanical anchorage and therefore exhibits lower tensile bonding strength with concrete, limiting its use in load-bearing or critical structural components.

Price of Plain Rebar
The price of plain rebar, like other steel sections, is never fixed and fluctuates based on several factors:
-
Raw Material Costs
The price of billets, a key input in steel production, directly impacts the final rebar price. Higher billet prices lead to increased rebar costs. -
Transportation Distance
The geographic distance between the manufacturing site and the construction project location affects the total cost due to varying fuel prices. -
Production Process and Equipment
Hot rolling, the process used to manufacture rebar, involves specific machinery and technology that also influence pricing.
