Description of BMP Z25 PPGI Rolled Steel Coil for Roofing Constrution
Cold Rolled Steel is pre-treated before being cold rolled with a process known as pickling, which uses strong acids to remove scale and other impurities.The Cold Rolled Steel is then passed through rollers to reduce its thickness. Most cold rolling takes place in multiple passes and as the size of the Cold Rolled Steel is further reduced, its strength and hardness both increase, but its ductility decreases.After cold rolling, heating the metal up in a process known as annealing can restore some of its ductility.

- Q:This question is directed to anyone who has played or know someone who plays a lap or pedal steel guitar.I've been a guitarist for about 8 years now and have played a variety of styles from rock, fingerstyle/classical, singer/songwriter acoustic stuff, ect, and now I've really had an interest in learning how to play a lap steel or pedal steel guitar. I am completely new to the instrument(s), so I'm seeking all the information I can. I do know that a pedal steel is a lot more expensive, so I'm probably looking to start on a lap steel for now. Basically how should I get started? Should I find a cheap lap steel at a pawn shop or purchase something new? Are there any good method books out there? I'm a pretty experienced guitarist, so should I expect to get the hang of it quickly? Is there much of a market for a lap/pedal steel player? haha.Also, I am left handed. How much trouble would it be to re-string a steel guitar? Or would I be better off getting a left-handed model?
- Hi, okorder /
- Q:What are the typical lead times for ordering steel coils?
- The typical lead times for ordering steel coils can vary depending on various factors such as the type and size of the coil, the supplier's production capacity, and the current market conditions. However, on average, lead times for ordering steel coils can range from a few weeks to several months. For standard-sized steel coils that are readily available in the market, lead times are generally shorter and can range from a few weeks to a couple of months. This is because suppliers often maintain a stock of these commonly used coil sizes to meet immediate customer demands. However, it's important to note that lead times can still be influenced by factors like transportation and logistics. On the other hand, if you require custom-made or non-standard steel coils, lead times can be longer. These coils usually involve additional processes such as specialized cutting, shaping, or coating, which may require more time for production. Lead times for custom-made steel coils can range from a few months to even six months or more, depending on the complexity of the specifications and the supplier's production capabilities. It's worth mentioning that lead times can also be affected by external factors like market demand and availability of raw materials. During periods of high demand or when there are supply chain disruptions, lead times may be extended as suppliers need to adjust their production schedules accordingly. To accurately determine the lead times for ordering steel coils, it is recommended to reach out to specific suppliers or manufacturers. They will be able to provide you with the most up-to-date and accurate information based on your specific requirements and the current market conditions.
- Q:What are the different types of steel coil edges?
- Various steel coil edges exist, each possessing unique characteristics and applications. 1. Mill Edge: The most prevalent type, it is obtained by cutting the coil at the mill without undergoing any further processing or treatment. Mill edge coils have a natural, slightly rounded edge, making them suitable for a wide array of applications. 2. Slit Edge: Slit edge coils are created by cutting the coil across its width using a slitting machine. This results in a straight and smooth edge, making them ideal for precise measurements needed in automotive parts or electrical components. 3. Deburred Edge: Deburred edge coils have undergone an additional process to eliminate any burrs or sharp edges that may exist after slitting. This ensures safer handling and reduces the risk of damage during fabrication or installation. Deburred edge coils are commonly used in the construction industry, particularly for structural steel components. 4. Rounded Edge: As the name implies, rounded edge coils possess a curved edge profile achieved through a specific rolling process. This creates a smooth and curved edge, making them often utilized in applications prioritizing safety, such as the manufacturing of household appliances or kitchen equipment. 5. Sheared Edge: Sheared edge coils are produced by cutting the coil using shearing blades, resulting in a straight edge with a slight burr. While sheared edge coils may have a rougher finish compared to other edge types, they are still frequently used in applications that do not require a high level of precision, like general fabrication or shelving. In summary, the choice of steel coil edge depends on specific application requirements, including factors such as measurement precision, safety considerations, and aesthetic preferences.
- Q:How does stainless steel soap work? I have read the detailed explanation on Wikipedia, but their desciption seems skeptical on the actual chemical process that may take place from using such an item. Is there an actual scientific explanation to how stainless steel soap is able to clean your hands, when it is only a piece of metal?
- Many metals have germicidal qualities. Silver is the strongest germicide of the metals, but a sterling silver bar of soap would be expensive and it would tarnish. The tarnish would actually not affect the silver's ability to kill bacteria, but it would look bad and the tarnish would turn your hands black, so people wouldn't want to use it. Many people even take silver internally in the form of Colloidal Silver, but Colloidal Silver is very controversial. Yes, it kills many bacteria, but it can also cause a person's skin to permanently turn blue...a condition called Argyria. Brass actually is a better germicide than stainless steel...but again this is a cosmetic problem. Brass tarnishes, so people wouldn't want to use it. Stainless steel is actually a very weak germicide, but even steel has some ability to kill germs. Stainless steel also removes fish odor. My son has a stainless steel bar that he takes along when he fishes to remove the fish smell from his hands. There's nothing magical about the bar...a stainless steel spatula would would just as well, but the bar is more convenient to carry. I'm not sure if this is scientific enough or not. -

- Q:Can steel coils be returned if they are damaged?
- Yes, steel coils can typically be returned if they are damaged. However, the return policy may vary depending on the supplier or manufacturer. It is advisable to contact the seller or review the terms and conditions of the purchase to determine the specific return policy for damaged steel coils.
- Q:How are steel coils used in the production of shipping containers?
- Steel coils are used in the production of shipping containers as they are formed and shaped into the required structure and size. The coils are unrolled and cut into sheets, which are then molded and welded to create the walls, roof, and floor of the container. This process ensures the container's strength, durability, and ability to withstand harsh shipping conditions.
- Q:What is the difference between regular steel stainless steel? Why does steel rust but stainless wont? Is stainless some kind of alloy or something? Any knowledgeable input would be great. Thanx!
- There are many things in life that I wonder about. Being in the steel industry and selling stainless steel I have at one point in my life asked myself, why do they call it stainless steel? What makes it stainless? It doesn't take much to find out but here is a very brief synopsis of what makes stainless steel stainless so that you can check one more thing off the list in your quest for knowledge. Stainless Steel might or might not have been invented by a man named Harry Brearley in 1912. Steel has been around for hundreds of years but it hasn't always been stainless. Only after the exact combination of elements had been achieved did we start calling a certain type of steel stainless. His magic potion contained the keys to what is now called stainless steel. That being said, the true inventor of stainless is still an ambiguous cloud at best. However, this isn't a discussion on WHO invented stainless but what stainless is and how it's actually stainless. Here is a great article posted by British Stainless Steel Association in regards to the history of stainless as a whole, see here. So what is in this magic potion that makes a steel not stain or rust? As most of us know if you leave regular steel or metal out in the elements it will rust, oxidize, or stain. Why does stainless not stain? When Harry Brearley Brearley created a steel with 12.8% chromium and 0.24% carbon, that was believed to be the first ever stainless steel. Chromium is the element in stainless that improves the corrosion resistance by forming a chromium oxide film on the steel. This very thin layer, is what allows the steel to be impermeable to rust or staining and when placed under the right conditions, it can also be self-repairing to a certain extent. There you have it. The answer is Chromium. Chromium is the element when mixed w/other elements in the proper amounts to form the thin layer that protects the steel from rusting, staining or corroding. Hope that helps you in your pursuit of knowledge.
- Q:I bought a damascus steel knife. It will be used for display. Nothing like hunting/skinning. If It is just sitting around, will it rust? (assuming that it isn't getting wet) Thanks for the help.

- Q:What are the different types of steel coil surface treatments for corrosion resistance?
- To enhance corrosion resistance, different methods are utilized for treating the surface of steel coils. These treatments create a protective layer that prolongs the lifespan of the steel and prevents corrosion. Some commonly used treatments for corrosion resistance include: 1. Galvanizing: Widely recognized as an effective method, galvanizing involves applying a layer of zinc to the steel coil's surface. The zinc acts as a sacrificial anode, corroding before the steel, thus safeguarding it against rust and corrosion. 2. Chromate conversion coating: This treatment entails applying a chromate-based solution to the steel coil's surface. The chromate forms a thin film that serves as a protective barrier against corrosion. Moreover, it improves the adherence of paint or other coatings that may be applied subsequently. 3. Phosphating: Phosphating is a process where a phosphate coating is added to the steel coil. This coating establishes excellent corrosion resistance by chemically bonding with the steel surface. It also enhances the adherence of subsequent coatings or paints. 4. Organic coatings: These coatings comprise paint or epoxy and are applied to the steel coil to create a barrier between the steel and its surroundings. They offer corrosion resistance and enhance aesthetic appeal. The selection of organic coating depends on the specific application and the desired level of corrosion protection. 5. Zinc-rich paint: Similar to galvanizing, zinc-rich paint contains a high concentration of zinc particles. When applied to the steel coil, these particles provide sacrificial protection, preventing corrosion. This coating is commonly employed in harsh environments or for steel coils exposed to frequent moisture or saltwater. It is important to consider various factors such as the application, environment, budget, and required level of corrosion resistance when choosing a surface treatment. Consulting with a steel coil manufacturer or corrosion specialist is advisable to determine the most suitable treatment for a specific situation.
