Q:In construction, what types of stress require steel to be placed in footings?: Steel is always added to concrete to handle local 'tension' stresses. (Sometimes to provide extra compression in 'pre-stressed' applications, but the steel is still in tension.) Steel would be added to the lower section of footings to stiffen them to 'bridge' local 'soft spots' in the substrate.

Q:I'm not really sure if carbon steel is considered a metallic material.: yes its iron with carbon in it

Q:What are the common coil coating materials?: The common coil coating materials include polyester, polyurethane, polyvinylidene fluoride (PVDF), silicone polyester, and epoxy.

Q:Its big and expensive and i don't know if it would have a logical purpose but its sharp as hell and awesome. Anyways, its made from surgical steel and all i have found on the internet is that its probably 316L (w/e that means). I have another knife made from 440 stainless steel and as far as i know that is pretty much the hardest stainless metal. So why would the more expensive one be made from surgical steel?: Unfortunately okorder /

Q:I moved into a house which has a steel front door.When I touch the door it feels very cold to the touch in the winter.There is a storm door also and the weather stripping looks good.Cold air from the door is entering the lower level.The house is about 20 yrs old.: Now a days crime has increased a lot, so we have to take protection and when the protection came to our house there came steel doors. The best ever protection in our houses. Source - www.scoop.it/t/qualitas-steel-doors

Q:Can steel coils be perforated?: Yes, steel coils can be perforated. Perforation involves creating a series of holes or small openings in the surface of the steel coil, which can be done for various reasons such as improving ventilation, reducing weight, enhancing aesthetics, or facilitating specific applications.

Q:What are the different methods of forming steel coils into sheets?: There are several methods of forming steel coils into sheets, each with its own advantages and applications. 1. Hot rolling: This is the most common method used to form steel coils into sheets. In this process, the steel is heated above its recrystallization temperature and then passed through a series of rollers. The rollers apply pressure to the heated steel, reducing its thickness and elongating it into a sheet. Hot rolling produces sheets with a smooth surface finish and is suitable for a wide range of applications. 2. Cold rolling: This method involves passing the steel coil through rollers at room temperature. Unlike hot rolling, cold rolling does not require heating the steel. The cold rolling process results in sheets with a higher dimensional accuracy and a smoother surface finish. Cold-rolled sheets are often used in applications where precise dimensions and a polished appearance are required, such as automotive body panels and appliances. 3. Annealing and pickling: This method involves subjecting the steel coil to a heat treatment process called annealing, followed by pickling. Annealing involves heating the steel to a specific temperature and then slowly cooling it, which helps to relieve stress and improve the material's mechanical properties. Pickling is the process of removing impurities and scale from the steel surface. These steps are typically performed before hot or cold rolling to ensure a high-quality end product. 4. Galvanizing: Galvanizing is a process that involves coating steel sheets with a layer of zinc to provide corrosion resistance. The steel coil is first cleaned and then immersed in a bath of molten zinc. The zinc adheres to the surface of the steel, forming a protective layer that prevents rust and corrosion. Galvanized sheets are commonly used in construction, automotive manufacturing, and electrical appliances. 5. Electro-galvanizing: This method is similar to galvanizing, but instead of immersing the steel coil in a bath of molten zinc, an electric current is used to deposit zinc onto the surface of the steel. Electro-galvanizing offers similar corrosion resistance to traditional galvanizing but with a thinner coating. It is often used in applications where a thinner, more lightweight sheet is desired. In summary, the different methods of forming steel coils into sheets include hot rolling, cold rolling, annealing and pickling, galvanizing, and electro-galvanizing. Each method has its own advantages and is suitable for different applications based on the required surface finish, dimensional accuracy, and corrosion resistance.

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:which one(glass or steel)has more power and velocity? im planning on using my slingshot for hunting.: steel fo shizzle, glass can break, but steal goes threw. And wat are u hunting for dear? lol

Q:Are Steel Building Kits really helpful while erecting a steel building?: I put up a 30'x40' Mueller Steel Building from a bolt together kit 6 yrs ago. Fully insulated, 2 10'x10' roll up doors, 1 walk thru door, 3 windows, 2' overhang all around, and gutters. The building price minus the slab was about $9500. The only special equipment was a neighbor's large Farmall with a hay spike on the FEL that we used to lift the trusses in place. Then it was mainly cordless drills to put in LOTS of self tapping screws, circular saw with metal cutting blade, tall ladders, etc. Had help putting up the trusses and putting up the roof panels. Everything else I did by myself. Took about 6 wks, but that was only working weekends and maybe 3 evenings a week since that land is 30 miles from my house. Would have gone a lot faster with at least one helper.
