In the steel market, a long time people know, steel sales are to be tested before, and how to test steel is a problem we should talk about today. In recent years, the small steel many factory around the country, and some steel quality standards is mostly the product of these small processing plants. If the quality of these substandard rebar flows into the steel market and flows into the construction of millions of households, it will cause great risks to people's safety and property safety.
First, the sample must be reinforced the same model specifications, mechanical performance test specimens reinforced selection, not simply from the reinforcement end interception, generally is to cut about 1m before sampling, is due to the impact on the end of steel production to eliminate hot rolling, also want to pay attention to the purpose of random field sampling inspection sampling, so each specimen can be universally true.
Secondly, how to test the steel bar is also to look at the surface conditions, which, by technicians and reports, supervision engineers, as well as quality inspectors together for acceptance. Acceptance of the time should pay attention to: the reinforcement spacing, steel reinforcement diameter, specifications, shapes, lashing, multiples, welding position, with the drawings to compare, whether the screw thread tightening and so on.
Finally, we still have to pay attention to steel packaging, general small factory production of steel packaging are relatively scattered, and regular production of steel packaging manufacturers is very dense, and tags, qualification certificate, and relevant quality certificate are complete. I suggest you pay more attention to the purchase of steel.
