What are the Different Types of Rebar?  The compressive strength of concrete is tremendous. Incredible force is required to crush concrete. However, concrete has relatively weak tensile strength. Far less force is required to crack concrete by bending or twisting it than is required to crush concrete. To increase the tensile strength of concrete, reinforcing bar — rebar — is used  to increase the tensile strength of concrete . A variety of rebar lengths and diameters are available, but there are only six common types of rebar: European (a carbon, manganese, silicon, etc. alloy); carbon steel (basic “black” rebar); galvanized; epoxy coated; glass-fiber-reinforced-polymer (GFRP); and stainless steel. The different types of rebar each unique strengths and weaknesses.   Rebar: Reinforcing Steel Bar Specifications Reinforcing bars are hot-rolled using different steel materials. Most rebars are rolled from new steel billets, but others are rolled from steel debris or railr...

Nowadays,  rebar rock bolt  tunnel support technology has become an indispensable technology in coal roadway support. In the supporting system, rebar rock bolt is the most widely used product. Here are some details of how high quality rebar rock bolt is manufactured:     Rock bolt Tunnel support is an important direction of the development of coal roadway support. It is a technological revolution of coal roadway support. The progress of rock bolt tunnel support technology has accelerated the development of mining roadway industry. In the innovation of coal roadway technology, after years of research, Longton finally found the rock bolt support – extremely advantageous technology. The improvement of rebar rock bolt technology can greatly reduce the cost of coal roadway support, improve the safety mining work and improve the production efficiency to a new level.     Nowadays, rebar rock bolt tunnel support technology has become an indispensable tech...

Dia 28mm-950/1050 Thread Bar Product Description Hot rolled bars  are available on the website in all grades and sizes. Select the properties you purchased, such as diameter, hot rolled, cold rolled, corrugated, etc. Hot rolled  steel bars are stronger than galvanized steel bars. They prevent cracks in concrete. When used with concrete for construction, thinner concrete is fine. Hot-rolled steel bars are extremely long-lived, cost-effective and responsive. Hot rolled steel bars have proven useful in enhancing the functionality of many commercial enterprises. These include airports, agriculture, fencing, infrastructure and concrete slabs. When you buy hot rolled deformed rebar, you compare various international sellers and narrow down your options based on price, quality and reviews from previous customers. Length:  12m or as per customers' requirements Technology: Hot rolled, right hand Accessories: full hex nut , spherical hex nut, bearing plate, domed nut, anchor bolt, ...

Bearing Plate Product Description Anchor plate works closely working with the Nuts.   And there are different types like flat,domed,spherical plate etc. Anchor Plates  are wooden or metal plates attached to or embedded in brackets and used as anchors (such as for supporting cables). Anchor plates consist of steel plates with welded shear bolts used to connect steel elements to concrete elements. For this purpose, the anchor plates are concreted into the concrete elements. Shear bolts are used as anchors. When installed, the steel plate is flush with the surface, with no concrete on one side. On this side, welding of steel components is possible. Typical Application: Reinforcement of the nut tension and fixation. Different sizes can be processed according to construction requirements. Bearing plates  provide a larger bearing surface than standard cut washers, helping to distribute loads more efficiently. The square plate allows it to cover a larger area of surface area tha...

Spherical Hex Nut Product Description Spherical Hex Nut for High strength thread bar Hex nut is an important part of thread bar accessory, it is used in all kinds of highway, railway, municipal construction, large Bridges, soil nailing, foundation pit anchoring, slope anchoring and other engineering construction. Hex Nuts are flat nuts and Spherical nuts, flat nut (upper nut), Spherical nut (lower nut). Commonly used specification is divided into 20 mm, 25 mm and 32 mm, 36 mm, 40 mm, commonly used materials are divided into 45 #, 40 cr material, hardness value is between 28 and 35.   Normal there are full hex nut and spherical hex nut used in construction. There is also lock nut, which is shorter and thinner than normal hex nut in the tensioning end. Typical Application: Flat nut is often used for fixed end, Spherical nut is often used for tension end. Hex Nuts For Sale Hex nuts are the most used nuts in industrial and commercial applications. These hex nuts can be used on all type...

When steel is curved, it is important to keep the stress-strain curve ratio for mild steel in mind. Below is a stress-strain graph that reviews the properties of steel in detail. If tensile force is applied  to a steel bar, it will have some   elongation. If the force is small enough, the ratio of the stress and strain will remain proportional. This can be seen in the graph as a straight line between zero and point A – also called the   limit of proportionality . If the force is greater, the material will experience elastic deformation, but the ratio of stress and strain will not be proportional. This is between points A and B, known as the elastic limit. Beyond the elastic limit, the mild steel will experience plastic deformation. This starts the yield point – or the rolling point – which is point B, or the upper yield point. As seen in the graph, from this point on the correlation between the stress and strain is no longer on a straight trajectory. It curves from point ...
