9 Factors That Construction Bars Manufacturers And Buyers Should Keep In Mind
The construction industry is growing at an unimaginable rate with new and innovative designs and techniques. With such tremendous growth, building demolition is also happening in various parts of the world due to improper construction analysis, poor quality materials, and management.
In addition to this, buyers are leaning towards secondary construction bars manufacturers to manage their construction budget, which in later years they realize as a hazard. They are setting their traps by buying poor quality low budget bars and materials.
The first thing you should consider is Brand! Choose your brand wisely. All the other things will fall in the right place. Yet we curated a list for your consideration to buy the best quality TMT bars.
1. Manufacturing Process
The quality of the bars can’t be changed or altered after coming out from manufacturing. Whatever happens in the plant will be the deciding factor of the life span of the building.
Thermomechanically treated (TMT) bars are being manufactured by advanced Tempcore technology under three important processes namely Quenching, Self tempering, and Atmospheric cooling.
Hot rolled steel wires will be subjected to a rapid cooling system to strengthen the outer core of the TMT bars and ensure the inner softcore to improve ductility.
Higher carbon content paves the way for strength whereas low carbon content enables good weldability. The TMT bars manufactured under proper guidelines will be better for welding purposes and eliminate pre and post welding treatment.
Save Time!! Save Money!!
Good quality TMT bars from a reputed brand will undergo bend and rebend test, where the bars are bent to 180 degrees and verified their parallelity and crack resistance, in the latter test, the already bent bar will be subjected to boiling water for 30 minutes and then bent further to qualify their bendability in utmost conditions.
4. Chemical composition
The chemical composition while manufacturing will be an important checklist for the best quality steel bars. A perfect amount of sulphur, carbon and phosphorus and other ingredients and exclusion of unwanted materials like cast iron, non-metallic and non-ferrous materials will prevent its longevity.
5. Dimension tolerance
Dimension tolerances are permissible limits or limits of variation with which the manufacturing team or the construction team can drift from nominal measurements. In other words, this can be mentioned as a factor of safety.
Manufacturing bars with nominal values of BIS enables the perfect grades of TMT bars with Dimension tolerance.
6. Dimension tolerance
Like manufacturing TMT bars with the right specifications, choosing the perfect bars enables us to construct buildings cost-efficiently.
Grades of TMT bars vary to the different seismic zones.
Steel bars are an important factor to withstand the reversal of stresses, which means, during certain unexpected situations, the compression member should withstand tensile load and vice versa.
UTS (Ultimate Tensile Strength) / YS(Yield Strength) ratio determines the seismic property of TMT.
7. Rib structure
Rib structure might look like a trivial quality in TMT bars, but this is the reason for concrete and steel to bond stronger for long happy years.
With a touch and naked eye test, we can ensure the spacing and dimension of ribs on the outer surface.
8. Fire Resistance
Manufacturing steel bars with higher thermal ability provides higher fire resistance during unanticipated situations and climatic imbalances.
Check your brand which says that their TMT bars can withstand 400 to 600 degrees celsius.
TMT bar bundles will be weighed in tonnes i.e. 1000 kgs. Steel bars with uniform length and dimensions should be selected. Uniform sectional weight per unit will minimize steel wastage at a greater rate.
