Rebar (short for reinforcement bar) also known as reinforcement steel are steel bars or mesh used on structures made of concrete, brick, and other types of materials to reinforce them and give them strength. Concrete has very weak tensile strength (ability to withstand load) and therefore requires reinforcement bars and meshes to enhance their strength and prevent the concrete from cracking.
The ultimate strength of a concrete structure depends on the reinforcement material used and it is very essential that you consult experts in steel reinforcement mesh Brisbane for a suggestion.
Why do I need to use Rebars?
Concrete has brittle properties and over time it tends to crack. Moreover, due to varied climate conditions, concrete tends to expand and contract and thereby causes tension, resulting in a collapsed structure. Adding rebars and steel reinforcement mesh helps the structure to absorb and distribute the tension.
What is steel reinforcement mesh? How is it different from rebars?
Steel reinforcement mesh and rebars serve the similar purpose of providing concrete with tensile strength. Steel reinforcement mesh is nothing but a wire mesh made out of individual rebars. Although they serve a similar purpose, the choice depends on the structural needs.
Which is better – rebars or steel reinforcement mesh?
Both are useful and often the choice depends on the structure itself. For example, rebars are best used vertically while steel reinforcement mesh is better suited for slabs. Also, steel reinforcement meshes have the ability to shape the concrete structure, which rebars do not have.
To best understand what type of reinforcing will suit your building, consult an expert on reinforcing steel bar Brisbane.
What are the available types of Rebars and steel reinforcing mesh in Brisbane?
Rebars come in various sizes, types, and technical specifications. The correct and suitable rebar type depends on various factors including the structure to be reinforced, the use of the structure, climate conditions and so on.
Generally, rebars can be divided into the following types:
- Size: Based on the diameter rebars can be of 12mm, 16mm, 20mm, 24mm, 28mm, 32mm, and 36mm.
- Shape: Rebars generally come in three shapes/cross-sections – deformed ribbed bar, round/plain bar and deformed indented bar.
- Ductility: Based on the ductile strength it can be of low ductility, normal ductility or seismic (Earthquake) ductility.
- The material used and coating: Based on the material and type of coating there are a handful of rebar types – European rebar made principally of manganese, carbon steel, galvanized, epoxy coated, glass-fibre-reinforced-polymer (GFRP), and stainless steel.
Which rebar should I choose?
The choice of rebar is determined by the Building codes and engineering specifications. Moreover, these specifications also determine the placement, spacing, pouring technique, and curing time for the reinforcement. Due to the multitude of types of rebars and demanding specifications, the choice of rebars and reinforcement is better left with the experts in steel reinforcing mesh Brisbane.
How to properly install rebars and reinforcement mesh?
Reinforcement installation is a highly technical job and must be done by professionals having specialization in reinforcement techniques.
Poorly installed reinforcement mesh and rebars can cause damage to the structure and may even cause the structure to collapse under tough conditions.
Some examples of poor installation are:
- Using little or no steel in the concrete structure.
- Improper placement of rebar resulting in the rebars too close to the edge and resulting in rust and corrosion.
- Rebars and mesh shifting position when concrete is poured resulting in compromised strength.
- Using low quality or wrong specification of rebars and mesh.
Choosing the right type of reinforcement and proper installation is a highly complex process and must be done by a qualified professional and under the guidance of experts in the field.
