How can we ensure the quality and safety of the steel strands we use for construction
Steel strand is widely used in construction, mining, Bridges, power construction and other fields, so how to ensure the quality and safety of the steel strand we use for construction, which requires us to check all aspects from purchase to acceptance.
First of all, the finished steel strand is usually tightly wrapped with rust-proof aluminum paper. When purchasing, it is necessary to check whether the outer package is complete, check the nameplate parameters on the package, which indicates the brand, origin, strength level and other information of the steel strand. Pay attention to check and confirm.
Secondly, tear the wrapping paper to see the surface structure of the steel strand, the qualified steel strand surface is smooth, if the surface of the steel strand is found to be rough, or even deformed, indicating that there is a problem with the production process of this batch of steel strand, the quality of the safety risks, can not be used normally.
Then, we should pay attention to the production of steel wire raw materials, we know that the normal shape of steel wire is round, but there are some steel wire on the market is oval, we should pay attention to distinguish when purchasing. After looking at the shape, parameters, etc., the next need to use the vernier caliper and other corresponding measuring tools to measure the specifications of the steel strand to ensure that its specifications and quality meet the standard.
Finally, after the purchase of steel strand arrived at the scene to check and keep the delivery note and warranty and other materials, according to the standard of the on-site batch of steel strand sampling inspection, only specifications, models, mechanical properties inspection qualified steel strand can be used for engineering construction, acceptance of the first time to contact the seller to return or exchange
