Cold rolled steel coil / sheet-SPEC in good quality


Characteristics:

1. Commercial quality suitable for bending fabrication and simple forming; this is the type in greatest demand.

2. Drawing quality second only to that of SPCEN. Excellent uniformity.

3. Deep-drawing quality.With metallurgically controlled grain size, it retains its beautiful finish even after being deep-drawn.

4. Extra-low-carbon steel sheets with highest workability

 

Packing and Transport:

The packing of coils consists of anti-damp paper, PVC film, hardboard paper, steel box, strapped with steel strips, fitted with locks and edge protectors and guarantees the optimal condition of the delivered goods. Each coil can be additionally fitted with wooden/steel skids(eye to the side)or wooden pallets(eye to the sky).

 

 

Q: How are steel coils made?
Steel coils are made through a process called hot rolling, where a large slab of steel is heated and passed through a series of rolling mills to gradually reduce its thickness and shape it into a coil.
Q: What are the different methods of testing the mechanical properties of steel coils?
There are several methods for testing the mechanical properties of steel coils. Some commonly used methods include tensile testing, hardness testing, impact testing, and bend testing. Tensile testing measures the strength and ductility of the steel by applying a tensile force until it breaks. Hardness testing determines the resistance of the steel to indentation or scratching. Impact testing measures the ability of the steel to withstand sudden forces or shocks. Bend testing evaluates the flexibility and resistance to cracking of the steel by bending it to a specific angle. These methods help assess the quality and performance of steel coils in various applications.
Q: Iron melts faster when there will be low carbon in Iron.During steel making the molten Iron gets purified and alloying being done through the process. How the carbon is being controlled at Iron melting stage and what it is called?
Steel is usually made in a two-step process. As you may know, carbon, in the form of coke, is added to the iron ore during the initial smelting process. This is the first step. The conversion of iron ore into raw iron is accomplished with a blast furnace. Carbon dissolves with the iron during the smelting process. The amount of carbon in the iron is generally not controlled at this point as this would be too difficult, the excess carbon is removed in the next step. The result is pig iron which is crude iron that has a very high carbon content, and a large amount of impurities. Pig iron is almost as brittle as glass, and it is useless in this form. In most modern steelmaking operations, molten pig iron is tapped from the blast furnace three or four times per day- it is not allowed to cool. The liquid pig iron is carried in ladles directly to a Basic Oxygen Furnace which converts the pig iron into steel. The basic oxygen converter uses a stream of pure oxygen to burn off the excess carbon. Impurities are also burned off, particularly phosphorus, silicon, and sulfur (which damage the steel's properties.) These elements all have a much higher affinity for oxygen than iron does, so the iron itself remains unchanged. Once the carbon content and the impurities are reduced to the desired level. The oxygen is shut off, and the iron has now become steel. At this point other alloying elements may be added, such as chromium, manganese, or molybdenum. These elements improve the steel's properties, but also add to it's price. If necessary, more carbon can be added as well if the carbon content has accidentally dropped too low. Finally, molten steel from the basic oxygen furnace is poured off. It can be cast into ingots, billets, or thin slabs.
Q: Or is it a coating that is applied? If so what types of steel? Or what types of coatings?
No, usually they are just coated or galvanized. To make a steel that is truly more corrosion resistant raises it's cost quite markedly, where as coatings are pretty cheap. Almost all structural steel is just A36 mild steel (like 0.1% carbon, 0.05% Mn, and not much else). There are higher grades of structural steel, and bridges are made with truly more corrosion resistant carbon steels, but for a house it's just not the case.
Q: could someone please explain to me in detail the functions of stainless steel wall ties?
they tie the walls to the ceiling to keep it from being blow en off in a storm stainless steel wont rust and become weak

Q: What are the common quality issues with steel coils?
Some common quality issues with steel coils include: 1. Surface defects: Steel coils may have surface defects such as scratches, pits, or rust spots. These defects can affect the appearance and smoothness of the final product and may also impact its performance. 2. Dimensional variations: Steel coils may exhibit dimensional variations, such as thickness variations, width variations, or length variations. These variations can lead to difficulties in processing the steel and may result in inconsistent product dimensions. 3. Mechanical properties: Steel coils may have variations in mechanical properties such as yield strength, tensile strength, or hardness. These variations can affect the strength and durability of the final product and may also impact its suitability for specific applications. 4. Coating issues: Steel coils that are coated or galvanized may experience issues with the coating, such as uneven coverage, peeling, or adhesion problems. These coating issues can result in reduced corrosion resistance and compromised aesthetics. 5. Internal defects: Steel coils may have internal defects such as inclusions, voids, or segregations. These defects can weaken the steel and may lead to failure or breakage during processing or use. 6. Edge issues: Steel coils may have edge defects, such as burrs, cracks, or uneven edges. These edge issues can affect the handling and processing of the steel and may also lead to problems during fabrication or assembly. 7. Coil set or camber: Steel coils may exhibit coil set or camber, which refers to the curvature or bowing of the coil. This can result in difficulties during processing and may lead to distorted or misaligned products. To ensure the quality of steel coils, manufacturers employ various quality control measures such as rigorous inspection, testing, and adherence to industry standards and specifications.
Q: How are steel coils inspected for paint adhesion?
Steel coils are inspected for paint adhesion through various methods such as visual examination, tape test, and cross-cut adhesion test. These tests involve visually inspecting the surface for any paint defects, applying adhesive tape to check if the paint adheres properly, and making cross-cuts to assess the adhesion strength.
Q: Can steel coils be coated with polymer?
Yes, steel coils can be coated with polymer.
Q: How are steel coils weighed?
Steel coils are typically weighed using industrial weighing scales or load cells. These devices are capable of accurately measuring the weight of the coils, whether they are small or large in size. The coils are placed on the scale or load cells, and the weight is digitally displayed or recorded for further analysis or documentation.
