Steel Bar

A615 grade 40 steel is particularly advantageous when constructing materials need to withstand concrete compression. Strength is a key distinguishing factor between these two rebar grades. The minimum tensile strength for A615 grade 40 steel is 70.05 ksi, with a minimum yield strength of 40 ksi.

This specification encompasses deformed and plain carbon-steel bars available in cut lengths and coils for concrete reinforcement. Steel bars with alloy additions, such as those conforming to the Association for Iron and Steel Technology and the Society of Automotive Engineers series of alloy steels, are permitted, provided the final product meets all other requirements of this specification.

ASTM A615 is an American standard for deformed steel bars, typically available in diameters ranging from 9.5 mm to 43 mm and lengths between 6 m and 12 m. These bars are generally composed of deformed or plain carbon steel.

ASTM A615 is an American standard for deformed steel bars, typically available in diameters from 9.5 mm to 43 mm and lengths ranging from 6 m to 12 m. These steel bars, generally made of deformed or plain carbon steel, are widely used in various construction applications.

B500A grade steel is typically employed for steel mesh products, whereas B500B grade steel is utilized for steel bars. B500C steel is seldom necessary, and it is advisable for structural engineers to verify if B500B grade steel can be substituted for B500C, as B500C often entails a substantial cost overhead.

BS4449 is another standard for deformed steel bars, which is also categorized according to European standards. These steel bars are manufactured through the hot rolling process, indicating their suitability for general purposes, such as common construction projects.

A deformed bar, commonly referred to as rebar (short for reinforcing bar), is a steel bar or mesh of steel wires employed as tension devices in reinforced concrete and reinforced masonry structures. Its primary function is to strengthen and maintain the concrete in tension. The surface of deformed bars is typically patterned to create a stronger bond with the concrete.

Epoxy resin coated steel bars are created by applying an epoxy resin protective coating to the surface of regular steel bars using an electrostatic spraying powder high-temperature sintering process. This coating offers outstanding chemical corrosion resistance and does not react with acids and alkalis. Additionally, it provides anti-permeability.

Galvanized reinforcing steel refers to bare reinforcing steel coated with a protective layer of zinc metal. This zinc coating acts as a barrier against corrosive elements that the rebar is exposed to when embedded in concrete.

B1499.2-2007 is a European standard for steel bars. Typically, GB1499.2-2007 standard deformed steel bars are produced using the hot-rolled method, making them the most prevalent type of deformed steel bars. These bars are offered in various lengths and sizes, ranging from 6 mm to 50 mm in diameter.

TMT, or Thermo Mechanical Treatment, refers to a thermomechanical process used to enhance the properties of steel bars. These TMT steel bars are commonly utilized in construction to provide improved protection against earthquakes and other natural disasters. It is crucial for TMT steel bars to exhibit corrosion resistance in order to ensure the safety and durability of the structure.
