What Is High Strength Thread Bar
Whether you are building a concrete slab for a driveway or a 40-story office building, reinforcing steel is an essential element of a concrete foundation, providing the required tensile and compressive strength.
Reinforcing steel (often called rebar and rebar mesh) is made from a raw material called iron ore. It is used in concrete to provide additional strength because concrete has a weaker tensile strength while steel has a higher tensile and compressive strength. This makes steel and concrete like gin and tonic; they are very effective together and go hand in hand!
It turns out steel and concrete have similar coefficients of thermal expansion, which means as the temperature changes (during day and night, season to season) that the structure experiences minimum stress in any structural elements, like beams, columns and slabs.
What type of steel is rebar and what is it made out of?
Reinforcing steel typically consists of carbon steel, which is hot rolled with deformation patterns (The ribbed profiles you see on the rebar and wire), allowing for a stronger bond to the concrete.
The steel bars and mesh are produced from iron ore and recycled steel in different steel mills around the world. While iron ore is an excellent material, using recycling steel is more energy efficient and has other benefits like reduced pollution and exhaustion of natural resources.
Understanding the codes of Steel Reinforcement Bar and Wire
Understanding the reinforcing steel codes can be confusing, as companies use different coding for their products. So, we have broken it down using the Australian standard codes, which we use today.
You may have seen the code ‘D500N12’, but as per industry standard it’s generally known by its abbreviated term ‘N12’.
Here is D500N12 broken down:
D = Deformed Rebar
500 = Yield Strength (MPa)
N = Normal Ductility
12 = Diameter (mm)
Just remember if the code starts with N i.e ‘N16’ the N represents (Deformed bar). ‘R’ (Round bar), ‘RW’ (Ribbed wire) or ‘W’ (Round wire).

What is a valve grinding machine?
Our Portable Relief Valve Grinder, Valve Seat Grinding Machine, Globe Valve Grinded Tool have the features that the front end of the spindle is equipped with a telescopic sleeve controlled by a pressure spring, and the axial pressure can be adjusted.
Chemical injection pumps are designed to improve well production, pipeline flow, and reduce corrosion. They operate under specific chemical and fluid requirements depending on the temperature and pressure with which the injection pump will be working at.
11 Kinds of Toys That Effectively Develop Children's Intelligence!
Parents are most concerned about the healthy growth of their children. In the face of problems that are not easy to solve, children can seek help from their parents, and the solution of problems is conducive to the development of children's abilities, and educating children is a worthwhile investment. Here are 11 effective toys to develop children's intelligence.
How Was Twisted Rope Invented And Made?
Rope has been manufactured for thousands of years. In addition to the materials used, the manufacturing process has changed dramatically. From water reeds and hand-spun tools to polypropylene and heavy machinery, advances in rope manufacturing methods have positively increased its capabilities and usefulness to those who use them.
Wafer type butterfly valves VS flange kind butterfly valves
The butterfly plate of the wafer type butterfly valve is set up in the diameter instructions of the pipeline. In the round channel of the butterfly valve body, the disc-shaped butterfly plate turns around the axis and the turning angle is between 0 ° and 90 °, which can play the duty of flow policy.
