هناك منتجات رديئة في جميع مناحي الحياة, الصلب ليس استثناء. لأن الفولاذ يستخدم بشكل رئيسي في المشاريع المتعلقة بسبل العيش والأمن, إنها مسؤولية اجتماعية رفض استخدام الفولاذ الرديء. هناك طرق مختلفة لتحديد أنواع مختلفة من الفولاذ. The following are several methods to recognize rebar:
First of all, we can use a vernier caliper to check if the actual size is smaller than the nominal size (عمومًا, there is a specification on rebar.) على سبيل المثال, the standard diameter of φ12 rebar is 11.5 ± 0.4mm, while the diameter of the fake one is only about 10mm.
Some manufacturers of counterfeit rebar also try to deceive customers by flattening their products. If observed from the end surface of the reinforcing bar, we will find it looks flattened or oval, but the end surface of normal rebar should be substantially circular.
Besides, there are common defects with fake steel, such as scarring, and an overall sense of roughness, and the surface color is reddish.
Regular steel is often packaged in large bundles, hung with metal tags, indicating the producer, steel grades, batch numbers, تحديد, and inspection code. But most of the shoddy steel is packaged in small bundles (about ten pieces) or in bulk, without the metal plate or quality guarantee.
As for the internal quality of steel, إنه, its strength and chemical composition of cold-formed physical and chemical properties can only be determined by sampling inspection.
لذلك, we recommend that users should purchase rebar in regular metal business units or business points, asking for a quality certificate and checked for acceptance. For confirming the quality of the rebar, we can go to professional testing agencies for quality advice and testing.
