How do I use the finishing nuts safely?　　
It has a direct impact on the life expectancy of the rolled rebar and the safety of the entire erection process, so it is important to ensure that each rolled rebar is evenly stressed after the tension is completed.

1. Surface adhesion containing acids, alkalis and salts (e.g. alkaline water or lime water splashes from decorated walls), causing local corrosion.
 2.in the polluted air (such as a large number of sulphide, carbon dioxide, nitrogen oxide atmosphere ), condensation, the formation of sulphuric acid, xiao acid, acetic acid liquid point, causing chemical corrosion.
      Measures to prevent damage to the fine rolled nuts are: each repair should be newly replaced in the connecting rod bolt inspection, should pay attention to the head of the fine rolled nuts, guide part, thread ministries whether there are cracks or dents, fine rolled nuts price, thread tooth shape, pitch is abnormal, there are abnormalities should be resolutely not used. When assembling the connecting rod cover, apply a torque spanner and torque it according to the prescribed standard to prevent the torque from being too large or too small.
  The use of a finish-rolled rebar connector: for example, 45# and 40Cr. In construction, when a finish-rolled rebar is not long enough and a second one is to be connected, it is necessary to use a connector to reinforce (anchor) the two rebar bars. As the name suggests, a finish-rolled connector is an anchorage that directly connects two finish-rolled rebar bars together, also known as a finish-rolled rebar connector and prestressing rebar anchorage.

 In terms of usage: Finely rolled rebar nuts are divided into finely rolled rebar flat nuts and finely rolled rebar taper nuts, which are used for anchoring connections of finely rolled rebar. Application areas are: highway bridges, railway bridges, urban interchanges, urban light rail, high-rise buildings, water conservancy and hydropower dams, ports and terminals, rock slope anchoring, foundation reinforcement, tunnel roof anchor roof, etc. Commonly known as nuts, the role of a wider range, commonly used in mechanical anchoring. Note: Usually when storing fine rolled nuts to pay attention to moisture, rust on the performance of the fine rolled rebar nuts will likely have a negative impact.
  It is an anchorage device used in prestressed concrete to maintain the tension of the prestressing tendons and transfer them to the concrete in post-tensioned structures or elements, also known as prestressing anchorage. The common specifications are 20mm, 25mm, 28mm, 32mm, 36mm, 40mm and 50mm. The materials used are 45# and 40Cr. In construction, when one fine-rolled rebar is not long enough and a second one has to be connected, it is necessary to use a connector to reinforce (anchor) the two rebar bars. As the name suggests, a finish-rolled connector is an anchorage that directly connects two finish-rolled rebar bars together, also known as a finish-rolled rebar connector and prestressing rebar anchorage.
