Steel Rebar

Product Introduction of Steel Rebar

Steel Rebar is a type of steel bar used in concrete construction. By adding these bars, you create reinforced concrete. Whether your project includes slabs, walls, or columns, rebar helps prevent cracks from forming that would allow the project to crumble. While all concrete cracks, rebar, and reinforcing materials help control the location and extent of cracks. It also provides structural strength to the project.

Wholesale Rebar Suppliers

Shandong Baowu Steel Group Co. offers wholesale rebar to businesses across the United States. Rebar, or rebar, is a common type of hot-rolled steel bar that is widely used in the construction industry, especially for concrete reinforcement. Rebar is most commonly used to reinforce concrete and other masonry tensioning devices to help hold the concrete in compression. Concrete is a material that is very strong in compression, but has little strength in tension. To compensate for this imbalance in the behavior of concrete slabs, steel reinforcement is cast in to carry tensile loads.

Ordinary rebar or concrete reinforcement has heavy ridges to help mechanically bond the rebar to the concrete, which is often referred to as deformed rebar.

Harris Supply Solutions stocks a variety of sizes, grades and finishes of rebar, including black rebar, epoxy coated rebar and fabricated rebar. We are committed to providing our customers with what they need, when they need it. As a subsidiary of Nucor, we have access to rebar throughout the United States through Nucor Trading, and internationally when necessary. We can find what you’re looking for, no matter what it is.

Why is reinforcing steel important in my project?

Reinforcing steel increases the damage resistance of concrete several times. It provides tensile strength using corrosion resistant rebar. If you want to structuralize your concrete, rebar provides stronger support than steel wire, reinforced fiberglass and many other products on the market. Why? Because it provides structural strength all by itself.

Different types of rebar

There are various types of rebar available in the market.

Carbon steel rebar is the backbone of concrete work. It is used in most concrete placements. Why? It is less costly and provides solid strength.
Glass fiber reinforced polymer GFRP is an alternative to traditional steel reinforcement. Using glass fibers, reinforcing bars are made into rods to provide reinforcement. It is stronger in terms of tensile strength.
Galvanized rebar is used in situations where corrosion may be a problem. Rebar is coated with zinc using several different processes. These include cold plating, hot plating or electroplating. The zinc provides a protective barrier on the steel.
Stainless steel rebar is used in corrosive environments where zinc cannot be used because of its electroplating action. It tends to be more expensive than galvanized rebar. For this reason, it is only used when absolutely necessary.
Epoxy coated rebar is a modern and economical option for use in corrosive environments. Rebar is coated with epoxy resin to protect it from corrosion. However, it may not be the best choice in environments where substrate movement, cracks or mechanical movement could damage the protective coating, allowing corrosive materials to enter the steel.
European steel is measured in a different format than what we see in the US market. They still provide solid reinforcement for your concrete structure.
Different rebar sizes and grades can provide different levels of strength. This makes it relatively easy for you to choose the right solution for your project.

FAQ

The corrosion resistance of stainless steel coils decreases as the carbon content increases. Therefore, the carbon content of most stainless steels is low, up to 1.2%, and some steels have a low ωC (carbon content) of even less than 0.03% (such as 00Cr12). The main alloying element in stainless steel coil is Cr (chromium). Only when the Cr content reaches a certain value, the steel has corrosion resistance. Therefore, the goods Cr (chromium) content of at least 10.5%. Stainless steel coil also contains Ni, Ti, Mn, N, Nb, Mo, Si, Cu and other elements.

Most of the requirements for use are to maintain the original appearance of the building for a long time. In determining which type of goods to choose, the main considerations are the required aesthetic standards, the corrosiveness of the local atmosphere and the cleaning system to be used. However, other applications are increasingly seeking structural integrity or impermeability. Examples include roofs and sidewalls of industrial buildings. In these applications, construction cost to the owner may be more important than aesthetics, and the surface may not be very clean. The use of 304 stainless steel coils in dry interior environments is quite effective.

Weldability. Different product uses have different requirements for weldability. A class of tableware generally does not require weldability, even including some cookware companies. However, most products require raw materials with good weldability, such as second-class tableware, insulation cups, steel pipes, water heaters, water dispensers, etc.

 


Corrosion resistance. Most stainless steel coil products require good corrosion resistance, such as Class I or Class II tableware, kitchen utensils, water heaters, water dispensers, etc.

 


Polishing performance. In today’s society, stainless steel coil products in the production process are generally polished, only a few products such as water heaters, drinking fountains, etc. do not need to be polished. Therefore, this requires raw materials with good polishing performance.

1. The need for pre-treatment
Pretreatment is an important treatment step before the surface of stainless steel coil parts enter surface treatment (including pickling, chemical polishing and electrochemical polishing, electroplating, passivation, black coating, coloring, chemical treatment, etc.). During the forming process of goods parts, the surface may adhere to oil stains, burrs, rough surfaces and oxides. Therefore, before surface treatment, oil stains, burrs, uneven surfaces and oxides must be removed in order to obtain subsequent satisfactory results through processing.

2. Treatment of removed dirt

Stainless steel coil surface pretreatment in the need to remove the dirt can be divided into two categories: organic and inorganic substances.

(1) organic dirt. Including mineral oil (such as diesel, oil, paraffin, gypsum, etc.) and animal oil, vegetable oil (such as soybean oil, camellia oil, rapeseed oil, lard, butter, etc.). These oils are mainly from the stainless steel coil zero cattle processing process used in the lubricant. , cutting oil, quenching oil, polishing paste and polishing paste, and fingerprints.

(2) Inorganic dirt. Including dirt, dust particles, oxides and other contaminants generated during the heat treatment process.

3. Pretreatment steps for stainless steel coil parts

(1) The surface is mechanically leveled. Eliminate the roughness of the stainless steel coil surface, through mechanical polishing and grinding to achieve a surface finish.

(2) Degreasing. Remove the surface oil and dirt.

(3) Acid washing. Remove the oxides on the surface.

(4) Weak corrosion. Activates the surface to be treated, removes the surface passivation film, and exposes the metal crystal structure.

Stainless steel is a high-alloy steel, with a large resistance to rolling deformation. In order to carry out high-efficiency and high-precision rolling, rigid rolling mills should be used, generally multi-roller cold rolling mill.

 


Special welding process is also a feature of cold-rolled stainless steel coil production.

 


In the production process of cold rolled stainless steel coil, the raw material (hot rolled coil) should be annealed, intermediate annealing should be carried out in the cold rolling process, and the final product should be annealed, so annealing is an important part of the production.

 


Cold-rolled stainless steel is a high-grade steel products, there are strict requirements for surface quality. Not only are metallurgical defects caused by the previous process not allowed, but also obvious defects caused by the cold rolling process.
