FAQ

1. Do you have QC team?
Yeah, sure, our QC team is very important, they will keep the quality control for our products.for quality inspection every day.

Q: How are steel coils secured during transportation?: Steel coils are typically secured during transportation using steel strapping, bands, or wire rope. These securements help prevent the coils from shifting or falling off the transportation vehicle, ensuring their safe delivery to the destination.

Q: What is the average surface finish tolerance for steel coils?: The average surface finish tolerance for steel coils can vary depending on the specific requirements and applications. However, commonly accepted standards for surface finish tolerance in the steel industry range between 10 to 20 microinches (0.25 to 0.5 micrometers).

Q: What are the different types of steel coil surface appearances?: The different types of steel coil surface appearances include mill finish, galvanized, painted, polished, and coated.

Q: How are steel coils processed and treated?: Steel coils are processed and treated through a series of steps. Initially, the steel is cleaned and pickled to remove any impurities. It is then passed through a series of rolling mills to reduce its thickness and increase its length. The coils are then annealed to improve their strength and ductility. Further treatments such as galvanizing or coating can be applied to enhance corrosion resistance or improve aesthetic appeal. Finally, the coils are cut and packaged according to customer specifications before being shipped for various applications in industries such as construction, automotive, and manufacturing.

Q: What are the typical coil width options?: The typical coil width options vary depending on the industry and application, but common options include 12 inches, 18 inches, 24 inches, and 36 inches.

Q: Can steel coils be stored in a corrosive environment?: Ideally, steel coils should not be stored in a corrosive environment as exposure to corrosive elements can lead to degradation and damage to the steel surface. Corrosion can weaken the structural integrity of the coils and affect their performance. To ensure the longevity and quality of the steel coils, it is best to store them in a dry and non-corrosive environment.

Q: What are the different types of steel coil storage methods?: There are several different types of steel coil storage methods, including vertical stacking, horizontal stacking, coil cradles, and coil racks.

Q: How are steel coils inspected for coil weight accuracy after processing?: Steel coils are inspected for coil weight accuracy after processing through the use of weighing scales or load cells. These devices measure the weight of the coil and compare it to the predetermined weight specifications. If the weight falls within the acceptable range, the coil is deemed accurate.

Q: the difference between the original steel and mild steel from percentage of carbon: Carbon steel includes mild steel. Mild carbon steel(as it is referred to) contains .05 - .29% carbon. Medium carbon steel is from .30 - .59%. High carbon steel is from .60 - .99%. Ultra high carbon steel is from 1.00 - 2.00%. Steel is considered carbon steel up to 2.1%. Past that it is considered cast iron. The more carbon in the steel the harder and less ductile and maleable it is and also the more brittle it is. The less carbon in the steel more it will bend and shape without breaking. So in essence carbon adds strength but takes away from its elasticity. If you are interested in this subject an interesting source is swordmaking where hardness(carbon content) is crucial. The information behind this subject is pretty infinite.

Q: What are the common surface finishes available for steel coils?: The common surface finishes available for steel coils include hot-dip galvanized, galvannealed, electro-galvanized, and painted finishes.
