Silicon: 0.2% to 0.6%
Sulfur and Phosphorus: Less than 0.05%
Benefits:
– It can withstand stress without breaking.
– Long-lasting and resistant to environmental stress.
– It can withstand high temperatures.
– Easy to weld for strong joints.
– Requires less material than TMT bars for the same strength.
5. Structural Steel
Structural steel is a good choice for building the main framework, including skyscrapers, industrial buildings, and large bridges. Due to its high strength-to-weight ratio, prefabrication facility, and durability, structural steel is a widely sought-after option due to its flexibility.
Composition:
Carbon: 0.12% to 0.25%
Manganese: 0.25% to 1.5%
Silicon: 0.1% to 0.6%
Sulfur and Phosphorus: Less than 0.05%
Benefits:
-It provides strength without adding excessive weight.
-It can be prefabricated, reducing Construction Structure time.
-Resistant to wear and tear.
-It can be used in a variety of construction applications.
6. Deformed Steel Bars
Deformed steel bars are also used for reinforced concrete structures in residential and commercial buildings. They come in various grades and sizes, making them suitable for construction projects.
