Q:They are showing on tv a special on how the new World Trade Center, building 1, is being built. Focusing on the steel and the guys fitting everything together.Where do builders go to buy all that steel framing? We do not build really tall buildings where I live so most of the steel is cut and welded on the job site. At World Trade Center 1, they seem to get the steel on trucks; already cut and welded.

Most of the parts are cut, welded, and fabricated indoors in a welding shop at another location. Then they're trucked to the site and simply need to be bolted together. This is made possible through the use of computer aided design and modeling programs, so that parts can be made to fit almost presciently in the field. They buy the steel from steel companies. I couldn't tell you exactly where it comes from, you'd have to ask the contractors themselves.

Q:Is infi steel as good as busse knives make it sound. If so why don't any other brands use it. Also are there any tactical folders that use infi steel. If infi isn't as good as it's cracked up to be then what is the best alternative.

Infi Steel Knives

Q:How are steel coils used in the production of HVAC systems?

Steel coils are used in the production of HVAC systems as a key component in the heat exchange process. They are typically used in the condenser and evaporator coils to transfer heat between the refrigerant and the air. The steel coils provide a durable and efficient surface for heat transfer, ensuring the HVAC system can effectively cool or heat the air.

Q:What are the different types of steel coil cutting machines?

There are several different types of steel coil cutting machines available in the market, each designed to cater to specific needs and requirements. Some of the commonly used types include: 1. Slitting Machines: Slitting machines are used to cut steel coils into narrower strips. They have multiple circular blades that make precise cuts along the length of the coil, allowing for the production of narrower coils or strips. 2. Cut-to-Length Machines: Cut-to-length machines are designed to cut steel coils into specific lengths. These machines can accurately measure and cut the coil to the desired length, ensuring uniformity and precision. 3. Rotary Shears: Rotary shears are heavy-duty cutting machines that can handle thicker and larger steel coils. They use a rotating blade to cut through the coil, making it suitable for cutting thicker gauge materials. 4. Multi-Blanking Machines: Multi-blanking machines are designed to cut steel coils into multiple smaller blanks simultaneously. These machines can cut the coil into various shapes and sizes, making them ideal for producing multiple parts from a single coil. 5. Slit and Cut-to-Length Combination Machines: These machines combine the functionalities of slitting and cut-to-length machines, allowing for both narrow strip cutting and length cutting in a single process. They are versatile and efficient, saving time and increasing productivity. Each type of steel coil cutting machine has its own advantages and is suitable for specific applications. The choice of machine depends on factors such as coil thickness, desired strip width, required length accuracy, and production volume.

Q:What are the common coil slitting methods?

The common coil slitting methods include rotary shear slitting, loop slitting, and oscillating slitting.

Q:How are steel coils coated to prevent rust and corrosion?

Steel coils are coated to prevent rust and corrosion through a process called galvanization, wherein a layer of zinc is applied to the surface. This zinc layer acts as a sacrificial barrier, protecting the steel from exposure to moisture and oxygen, thereby preventing rust and corrosion.

Q:I just bought a used Taurus 85 stainless 38 spl revolver, it's about 25 years old but looks like new. This is my first stainless steel gun. I'm wondering if there's any special things I need to be aware of or cleaning methods? I'm also wondering if stainless steel could rust? in theory stainless means it cannot get stained or rusty. I have a chrome bore AK, cleaning is always super easy, wondering of cleaning a SS revolver would be the same.

Stainless steel does not rust. But your Stainless Barrel is not true stainless steel. True stainless steel is a mix of steel and chrome, and the chrome has a certaion percentage of the overal weight.. But a Stainless barrel does not contain enough chrome to be true stainless, so it can rust.

Q:Why is steel used for building purpose and not any other metal?

Steel is used over most other metals due to its desireable properties for buildings. To name a few: strength, hardness, ductility, conductivity, flexability, weight, ability to shape/mold, non-combustability, weather resistance and cost Many other metals have the same properties, only on different scales. For instance, copper may be an excellent conductor, howwever it's expensive and not very weather resistant. Aluminum may be flexible, moldable, but not very strong. The list goes on and on..

Q:Two different shaving razors I'm looking to buy have different specs. in terms of the metals used for the blade; one being 1045 surgical stainless steel, the other 440 stainless (not sure if its A B or C, but probably 440A or 440B because it's not specified). So which one is better for the intended use as a shaving razor?

1045 stainless is better

Q:i want to know what is light gauge steel and the diffrences between light gauge steel and steel for roof truss.

guage means thickness.
