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, foundation bolt, couplers, spring bar Packing: in bundles Delivery: 15-30 days COMPOSITION: The PSB950 thread bar is made of black steel with a continuous right-handed along the entire length of the thread bar.

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 than a standard round gasket. This makes them ideal for fasteners required for heavy duty applications.
