Material issue
Thread Content
I bought channel steel made of material 201 for structural use, only to find this situation below, which is really worrying
201 is prone to cracking, and its quality is a bit concerning
Hehe, if materials are selected based on codes, then who will verify whether they match? It’s better to choose products from well-known, major manufacturers to ensure reliability. But it’s expensive, and it lacks other ingredients: lol So, if you have the choice, it’s best to avoid using products from unknown companies.
If such steel sections are used, problems will arise in no time; fortunately, it was discovered during the installation phase~~~~~~~~~It’s necessary to have a discussion with the procurement department~~
It’s outright fake and inferior quality product; file a complaint with the Quality Supervision Bureau against them – there’s sure to be some interesting developments.
Non-standard steel, steel produced by small factories, illegal steel – it’s not just these; the same issue applies to angle steel, channel steel, and I-beam as well! Heartbreaking!
Material 201 has poor weldability and is not recommended for use. Additionally, this material seems to be produced by a small factory; when making the purchase, only the price was considered – you get what you pay for
Replace it; what kind of thing was this purchased?
There is a problem with the material; it is recommended to purchase steel from reputable, large manufacturers.
