We have established the international advanced quality management system，every link from raw material to final product we have strict quality test；We resolutely put an end to unqualified products flowing into the market. 、2. How long can we receive the product after purchase?

Usually within thirty working days after receiving buyer’s advance payment or LC. We will arrange the factory manufacturing as soon as possible. The cargo readiness usually takes 15-25 days, but the shipment will depend on the vessel situation.

Q: What is the width range of steel coils?: The width range of steel coils can vary depending on the specific type and purpose of the coil, but it typically falls within the range of 600 mm (23.6 inches) to 2,200 mm (86.6 inches).

Q: I felt that my nylon strings don't sound as good as steel ones. Is it okay that I replace them with steel ones, even if my guitar is classical? Thanks.: I think so, I've never played classical, only acoustic and electric but my neighbor has a classical and he has all steel strings on it.

Q: What are the different types of steel coil slitting methods?: There are three main types of steel coil slitting methods: rotary slitting, loop slitting, and pull-through slitting. Rotary slitting involves using circular knives to cut the coil into narrower strips. Loop slitting involves passing the coil through a loop that is formed between two sets of knives, which then cuts the coil into multiple strips. Pull-through slitting involves pulling the coil through an adjustable slitting head, where the knives cut the coil into desired widths.

Q: What are the common certifications required for steel coils?: The common certifications required for steel coils include ISO 9001 (Quality Management System), ISO 14001 (Environmental Management System), and OHSAS 18001 (Occupational Health and Safety Management System). Additionally, certifications like ASTM (American Society for Testing and Materials) and EN (European Norm) standards are important for ensuring the quality and compliance of steel coils.

Q: What are the different methods of stretch leveling steel coils?: There are several methods of stretch leveling steel coils, each with its own advantages and applications. 1. Roller Leveling: This method involves passing the steel coil through a series of rollers that apply pressure to stretch and flatten the material. It is a widely used method for leveling steel coils and offers good control over the leveling process. Roller leveling is suitable for thin and medium gauge steel coils. 2. Tension Leveling: In this method, the steel coil is subjected to high tension forces applied by a set of bridle rolls. The tension helps to elongate and flatten the material, resulting in a level and stress-free coil. Tension leveling is particularly effective for thicker and harder steel coils. 3. Laser Leveling: Laser technology is employed in this method to measure and correct any imperfections in the steel coil. A laser scanner scans the surface of the coil and detects variations, which are then adjusted by a laser beam. Laser leveling offers high precision and is suitable for leveling sensitive and high-value steel coils. 4. Stretcher Leveling: This method involves stretching the steel coil beyond its yield point, which causes the material to permanently deform and eliminate any residual stresses. Stretcher leveling is commonly used for heavy gauge coils and can achieve significant flatness improvements. 5. Tensionless Leveling: As the name suggests, tensionless leveling is performed without applying tension to the steel coil. Instead, hydraulic or pneumatic pressure is used to stretch and flatten the material. This method is suitable for delicate or sensitive steel coils that may be prone to damage under high tension forces. Each method of stretch leveling steel coils has its own advantages, such as control, precision, or suitability for specific types of steel coils. The choice of method depends on factors like the thickness, hardness, and quality requirements of the steel coil, as well as the desired flatness and surface finish.

Q: My string on my acoustic guitar broke. Can I replace all of my strings with phosphor bronze guitar strings if my guitar has steel strings on them?: Phosphor bronze strings ARE steel strings. Phosphor bronze is the alloy used to wrap the steel core on the bottom four strings (the top two are plain steel). It's probably the commonest wrap material used for steel-string acoustics, and most likely it's what you have now. You can also get 80/20 (brass) if you prefer, or fancy coated strings. All will have the basic steel core and are considered steel strings. If your strings have been on there a while, it is better to replace the entire set. Even if none break, replacement at about 3-month intervals is a good idea as the strings gradually lose their tone.

Q: what are the characteristics when of iron or steel when stretched? which one could be stretched further? which one stretches more evenly?thankyou: Technically, this is known as ductility. a material which can be permanently bent and stretched is said to be ductile. Pure iron, when it lacks carbon and impurities like sulfur and phosphorus, is relatively soft, ductile, and weak. It's about as soft as brass. It can be stretched to about 50% of it's original length before it breaks. The amount a sample can be stretched without breaking is known as elongation. The key to steel is the addition of about 2 parts per thousand of carbon, or around 0.2%. This alters the crystal structure and makes steel much harder, stronger, and tougher, though it also becomes somewhat less ductile. Mild steel, with a low carbon content, has an elongation of around 30% Adding more carbon makes the steel yet stronger, but further reduces the elongation. Adding more than 2-3% carbon produces what is known as Cast Iron. Cast iron is brittle. It has virtually no ductility. It's pretty cheap to produce though.

Q: How are steel coils used in the manufacturing of industrial pumps?: Steel coils are used in the manufacturing of industrial pumps as they provide a strong and durable material for constructing pump components such as casings, impellers, and shafts. The coils are typically cut, shaped, and welded to create the necessary parts, ensuring the pumps can handle high pressures and harsh operating conditions in various industries.

Q: Cold rolled steel coil steel, what is the difference?: Hot rolling is made of slabs (mainly continuous billets) as raw materials. After heating, strips are made from roughing mills and finishing mills.

Q: I have a set of steel pans with copper bottoms. When I cook with oil it always burns the oil to the pan and takes days to clean. I don't think I should use steel wool, since it might scratch the surface. Does anyone know a faster way to clean scorched oil off a steel pan?: Use a Mr. Clean Magic Erasure. I swear, you will be amazed at how easily it gets your pots and pans clean! It shines them right up! That oil will come right off. Make sure you do wash it with dish soap and warm water after using the Magic Erasure.
