How to choose high-quality steel strands
Aug 28,2023
The prestressed steel strand is a very important building material at present. The prestressed steel strand is twisted by steel wire. Therefore, when using the prestressed steel strand, each steel wire should be prevented from dispersing and affecting the use. At the time of procurement, the buyer must check whether the steel wires of the prestressed steel strand are in conformity with the fixation to avoid quality problems.
Use of steel strand
Steel strands play a vital role in construction projects. Due to its high tensile strength, steel strands are widely used to strengthen concrete structures and improve the stability and bearing capacity of buildings. It can be used to strengthen beams, columns, plates and other components to effectively prevent damage and deformation caused by load. In addition, steel strands can also be used to strengthen bridges and enhance their seismic resistance and durability.
Operation method of steel strand testing machine
The steel strand testing machine is an instrument used to test the strength of steel strands. It can measure the tensile strength, elongation at break, elastic modulus and other parameters of steel strands. The following describes the operation method of the steel strand testing machine:
Stabilizes the building skeleton, and the steel strand assists the safety of the structure.
In modern architecture, structural stability and safety are of paramount importance. As a strong structural material, steel strand provides reliable support for the building skeleton and helps to build a safer and more stable building.
Pouring of Prestressed Concrete Lining Completed in Project B3 of Pearl River Delta Water Resources Allocation Project
With the completion of the last concrete pouring, the prestressed concrete lining of B3 bid project of Pearl River Delta Water Resources Allocation Project undertaken by Guangdong Hydropower has been completely poured.
Application of prestressed steel strand
Prestressed steel strand is mainly used for post-tensioned prestressing and pre-tensioned prestressed concrete engineering. Die-drawn steel strands are mainly used for lifting projects, but also for projects such as nuclear power. 19 wire large diameter steel strand is often used in mine supporting anchor cable. Unbonded prestressed steel strands are commonly used in building slabs and some geotechnical anchor cables.
Material of prestressed steel strand
The prestressed steel strand is mainly made of high carbon steel cold drawing, with trace phosphide and lubricant residue on the surface.
Steel strand for prestressed concrete
Ordinary steel strand (I. e. bonded prestressed steel strand) is made of high carbon steel wire rod, which is cold drawn into steel wire after surface treatment.
