To meet social development needs, the construction of infrastructure has become a top priority. This makes the building materials industry competition increasingly fierce, and some small companies inevitably reduce the quality of their products to cut costs. Below we will mainly discuss the following points on how to regulate the correct production of enterprises with the example of rebar splice.

1. First, most regulated enterprises will choose 45# high-quality carbon steel as the material for rebar splice. Still, many small manufacturers use cold-rolled steel pipes because this can save the drilling and other processes by reducing processing costs. Still, it is not difficult to conclude because improper use of materials will certainly cause certain hidden problems.

2. The raw materials of each batch of reinforcing rebar splice must be analyzed by material chemistry and tensile strength test before entering the factory. From the point of view of the quality of raw materials, small manufacturers do not have the material into the plant inspection procedures, which also leads to small manufacturers of most of the raw materials using small steel mill materials, a ton of price difference can be in about 200 yuan. With the inspection fee, you can save material costs, but this will lead to the raw material strength, flexibility, stiffness, and other indicators not being met.

3. From the comparison of processing size, the standard enterprises following the size of carbon steel can meet the requirements of the outer diameter of the steel joint size to ensure that the sleeve cross-sectional area reduces the size of the outer diameter. You can save material costs. However, due to the reduction of the cross-sectional area of the steel joint, the length is shortened, easy to fracture off, and can not guarantee the connection of steel and other strong.

4. In the production process control of reinforcing rebar splice, quality-assured companies strictly implement the process route and inspect according to procedures. But small companies can be directly drilled inside the hole. The size and accuracy can not be guaranteed. The bore size is too large, and the tapered buckle is easy, but the consistency of the threaded middle and small diameter sizes cannot be guaranteed. Rolling straight threaded rebar joints transmit the rebar tension through the mechanical bite of the wire head and thread. This rebar joint is easy to pull off if used on construction sites.

5. From the comparison of the inspection process of reinforcing rebar splice, the standardized enterprises conduct 100% inspection from each procedure to the finished product to ensure that the main indexes such as outer diameter, inner diameter, middle diameter, length, and thread of reinforcing rebar splice are qualified. In contrast, small manufacturers only conduct sampling inspections for each process and even finished products during the production process, which reduces the inspection cost, but the quality cannot be guaranteed.

From the above five points, we can see that the black-hearted manufacturing enterprises, owners, and construction enterprises at the cost of public safety, jerry-built, but the management is not painful "not an example" lack of supervision; in such an illegal cost is the almost negligible trend, the quality of reinforcing rebar splice is inevitable.

So if you are ready to purchase these things, you must be asked either to choose a trusted manufacturer to buy or must be clear whether these reinforcing rebar splices are up to standard, whether tested. If you need more detailed information, welcome to contact us!
