Q:How are steel coils used in the production of storage containers?

In the production of storage containers, steel coils play a vital role. These coils, manufactured from high-quality steel, are crucial for constructing the walls, floors, and roofs of the containers. To begin the process, the steel coil is uncoiled and passed through a series of machines that cut and shape it into the desired dimensions. Then, the steel is transformed into panels, which are either welded or riveted together to form the container's structure. The strength, durability, and resistance to corrosion make steel coils an excellent material for storage containers. They provide a robust framework that can endure heavy loads and harsh environmental conditions. Moreover, the coils can be easily molded and customized to meet specific size and shape requirements. Once the structure of the container is complete, it is typically coated with a protective layer of paint or other coatings to further enhance its durability and resistance against weather elements. This ensures that the container remains unaffected by moisture, UV rays, and other external factors that could cause deterioration. All in all, steel coils are of utmost importance in the production of storage containers as they offer the necessary strength and durability required to safely store and transport a wide array of goods and materials.

Q:Looking for a new entry door for my home If someone would explain the features and benefits of both fiberglass and steel doors I would greatly appreciate it!!

Fiberglass doors insulate better than the steel doors and they do not dent or rust. Go with fiberglass.

Q:How are steel coils used in the manufacturing of suspension systems?

Steel coils are used in the manufacturing of suspension systems as they provide the necessary support and flexibility to absorb shocks and vibrations, ensuring a smooth and comfortable ride. These coils are typically used in coil spring suspension systems, where they are compressed and stretched to absorb and distribute the weight of the vehicle, maintaining stability and enhancing overall performance.

Q:How are steel coils coated or painted?

Steel coils are typically coated or painted using a process known as coil coating. This involves a series of steps including cleaning, pretreating, applying primer, and applying the final topcoat. The coils are first cleaned to remove any dirt or contaminants. They are then pretreated to enhance adhesion and corrosion resistance. After that, a primer is applied to provide a base layer for the paint. Finally, the desired topcoat is applied using various methods such as roll coating, spray coating, or electrostatic coating.

Q:Maybe it is obvious. But i have thought alot about it.I thought steel at a cool temperature was unbreakable. I am not one for science or physics or engineering (i am a political science major). But i don't understand why the planes that struck the world trade center on 9-11 didn't just dent the side and fall,How did the place break the steel? Was it the velocity? Is steel easily broken?I realized that i wasn't taught how the planes broke the steel, and that no one ever asked. I searched the web and i couldn't find the answer or even anyone who had asked the question before.(i don't care about conspiracy theories, i just want scientific facts)

I saw a one-hour program about this on PBS a couple of years ago. The buildings were constructed with the concrete-clad steel supporting columns at the center of the buildings, with a relatively thin lattice of steel struts along the outer wall. When the planes hit, they sheered through the thin steel struts easily by sheer momentum, while, at the same time, the thin steel stripped off the wings. The bodies of the planes got as far as the supporting columns in the center of the buildings, but were stopped there. The heaviest, densest pieces, the engines, went completely through the buildings and popped out the other side. It's important to understand that even light materials can cut through metal, if the light material is going fast enough. I saw this first hand, when I was in the Navy and stationed on board ship. We had a helicopter crash on our flight deck during heavy weather. The blades were made of light, carbon-composite material, but they were going so fast that they cut through the aluminum deck. I still have photos of that damage.

Q:What are the different methods of slitting edge trimming for steel coils?

There are several methods of slitting edge trimming for steel coils, including rotary shear slitting, crush cutting, and laser cutting. Each method has its advantages and disadvantages, depending on factors such as the desired precision, speed, and the type of steel being processed.

Q:What are the different certifications required for steel coil manufacturers?

There are several certifications that steel coil manufacturers may be required to have in order to operate in the industry. These certifications ensure that the manufacturers meet certain quality and safety standards. One of the most common certifications is the ISO 9001 certification, which is an international standard for quality management systems. This certification demonstrates that the manufacturer has implemented processes and procedures to consistently meet customer and regulatory requirements. Another important certification is the ISO 14001 certification, which is an environmental management system standard. This certification shows that the manufacturer has effective environmental management practices in place and is committed to minimizing their environmental impact. In terms of safety, manufacturers may be required to have certifications such as the OHSAS 18001 or ISO 45001 certifications, which are standards for occupational health and safety management systems. These certifications indicate that the manufacturer has implemented processes and controls to ensure the health and safety of their employees and stakeholders. Additionally, manufacturers may need certifications specific to the steel industry, such as the American Institute of Steel Construction (AISC) certification. This certification is specific to structural steel fabrication and erection and ensures that the manufacturer follows industry best practices. Furthermore, manufacturers may also need certifications related to specific product standards, such as the American Society for Testing and Materials (ASTM) certification. This certification ensures that the manufacturer's products meet specific quality and performance requirements. It is important for steel coil manufacturers to obtain these certifications as they provide credibility and assurance to customers that their products are of high quality, environmentally responsible, and meet industry standards.

Q:I have some steel wool and a charged 9V Battery, when I connect 2 wires to the battery, then touch the wool with the ends of the wires the wool instantly starts burning, but when I connect 2 wires to the piece of steel wool (a new piece not same one of course) and touch the battery with the ends of the wire nothing happens (see image...)

What's happening in the first case is that the initial contact of the wire to the steel wool is not very good and there is a high resistance as the touch is made and there is probably a slight spark that starts the steel wool burning. Now it is even harder to make good contact and the process continues. In the second case there is initially a good contact to the steel wool and there is no spark when the circuit is completed at the battery. It would be difficult to cause the heating and the spark at a distance unless you had a way to remotely cause the wire to lightly touch the steel wool. A gas lighter which uses a flint to create a spark is good for igniting a gas burner which will continue to burn by itself, but probably wouldn't cause the steel wool to burn without the energy coming from the battery to keep it going. Steel wool WILL continue to burn if it's in a pure oxygen atmosphere. You might try hooking the battery up to the steel wool as in the second case and using a spark lighter to start some burning close to one of the wire connections to see if the extra battery power might keep the burning going.

Q:Which steels were origianally designed to be used to cut and shape metals and other materials?- alloy steel- high carbon steel- carbide steel- tool steelthanks

Tool steels These were designed to be used as hardenable, dimensionally stable materials for cutting of metals. The alloying elements they contain (including tungsten, vanadium, niobium and molybdenum as well as chromium)are there to produce carbides (mainly) which are stable at dull-red heat. This cannot be achieved with high carbon steels, carbide steels or (normal) alloy steels which all lose their strength and hardness at metal cutting temperatures.

Q:What are the different types of steel coils available?

There are several types of steel coils available, including hot rolled coils, cold rolled coils, galvanized coils, stainless steel coils, and coated coils.
