Q: i was thinking like getting a a steel building for 2 or 3 stall does anyone know how much that would cost? Have anyone used steel building how do you like them etc: I have two steel barns, one is 4 stables. 15 x12 for 3 stables and the other 12 x 18 I have a large tackroom and an area for storing gardening and farm light machinery. (Chain saws. strimmers and fencing stuff.) The second barn has 4 stables 12 x 15. an 8' aisle and then two large loose shed areas. 30' x 50'. I can run these as one pen if I want. I have 45' x 70' at the other end for storing hay and straw. Haven't a clue to the cost but it wasn't cheap! Although it is all steel the lower walls of the stables are all blocks. I didn't want to line the steel with wood as they eat it for fun. The loose shed are lined with hard board.

Q: I work with stainless steel a lot and I know it's rust resistant but it's definitly not STAIN resistant. You might be able to remove some stains easier from it than you can from some other surfaces but when it does stain, its hard as heck to clean it. It takes forever to scrub stains off my stainless steel pans so maybe it should just be called rustless steel?: Because it stains less than some other metals.

Q: How do steel coils contribute to the energy infrastructure sector?: The energy infrastructure sector heavily relies on steel coils, which are essential for constructing and maintaining various energy-related structures and equipment. To begin, steel coils are extensively employed in manufacturing pipelines, the lifelines of the energy industry. These pipelines transport oil, natural gas, and other energy resources across long distances, guaranteeing a consistent supply to power plants and other energy facilities. The use of steel coils in producing seamless and welded pipes ensures high strength, durability, and resistance to corrosion, making them well-suited for handling the challenging conditions of energy transportation. Apart from pipelines, steel coils are also used in the production of storage tanks for oil, natural gas, and other fuels. These tanks play a crucial role in storing large quantities of energy resources, ensuring an uninterrupted supply even during periods of high demand. By utilizing steel coils to fabricate the tank shells, the necessary strength and structural integrity are achieved, enabling them to withstand the pressure and environmental factors associated with energy storage. Moreover, steel coils play a vital role in the construction of power plants and other energy infrastructure facilities. They are utilized in manufacturing structural components like beams, columns, and supports, which provide the foundation and stability required for the safe operation of these facilities. Additionally, steel coils contribute to the production of equipment such as turbines, generators, and transformers, which are essential for converting energy into usable forms and distributing it to end-users. Furthermore, steel coils are employed in the construction of transmission towers and electrical grids. These structures and networks are responsible for transmitting electricity from power plants to residential, commercial, and industrial consumers. By using steel coils to manufacture the towers and poles that support high-voltage transmission lines, their stability and reliability in transmitting electricity over long distances are ensured. In conclusion, steel coils are irreplaceable in the energy infrastructure sector, providing the necessary materials for constructing, maintaining, and operating pipelines, storage tanks, power plants, transmission towers, and electrical grids. Their strength, durability, and resistance to corrosion make them the ideal choice for withstanding the demanding conditions of the energy industry, thereby ensuring a reliable and efficient energy supply to meet the growing needs of society.

Q: How long can steel coils be stored?: Steel coils can be stored for an extended period, typically up to six months to a year, depending on the specific type of steel and its storage conditions.

Q: i want to know if i should buy a set of acrylic tapers or steel. they r close in cost so it's not a money factor i want to know which work better and if there is a downside to either. thanks!: Steel is better. Acrylic is porous so isn't as suitable for piercing jewellery as steel. Steel can also slide through easier for some people, acrylic isn't quite as smooth. For tapers it doesn't make a huge deal of difference as they're only passing through your ear briefly, not being worn as jewellery, but if they're close in cost anyway then go for the steel. And the plugs you insert after putting the taper through should always be steel, titanium or glass until your stretch has healed.

Q: How are steel coils tested for compliance with industry standards?: Steel coils are tested for compliance with industry standards through a series of rigorous quality control measures. These tests are conducted to ensure that the coils meet the necessary specifications and are suitable for use in various applications. One of the primary tests performed on steel coils is the dimensional inspection. This involves measuring the thickness, width, and length of the coils to ensure they meet the specified tolerances. Any deviations from the required dimensions can indicate a manufacturing defect or potential issues during fabrication. Another critical test is the visual inspection, where trained inspectors carefully examine the coils for any surface defects such as scratches, dents, or cracks. These defects can affect the performance and durability of the steel coils, making it essential to identify and rectify them before they are supplied to customers. Furthermore, mechanical properties testing is conducted to assess the strength, elasticity, and toughness of the steel coils. This includes tests like tensile strength, yield strength, and elongation measurements. These tests help determine the suitability of the coils for specific applications and ensure they meet the required performance standards. Additionally, chemical composition analysis is performed to verify the elemental composition of the steel coils. This analysis is crucial as it ensures that the steel meets the required chemical requirements, including the presence of specific alloying elements. Deviations in composition can impact the overall quality and performance of the coils. Corrosion resistance testing is also important, especially for coils used in environments with high humidity or exposure to corrosive substances. Coils are subjected to salt spray or humidity chambers to simulate real-world conditions and evaluate their resistance to corrosion. Lastly, various non-destructive testing techniques, such as ultrasonic testing and magnetic particle inspection, are used to detect internal defects or discontinuities in the steel coils. These tests help identify any hidden flaws that may compromise the structural integrity of the coils. Overall, steel coils undergo a comprehensive range of tests to ensure compliance with industry standards. By conducting these tests, manufacturers can guarantee that the coils meet the required specifications, providing customers with high-quality products that meet their specific needs.

Q: I want to know where cold formed steel framing is used, is every steel frame we see in a construction sites like houses, building and bridges cold formed steel frames? or hot formed steel framing?I also read that cold formed steel framing is used for floors, is the steel frame beneath the floor's concrete cover?Thank u very much!!: It will vary from location to location. A possible way of telling is how the material is joined. If the material is riveted together it is likely cold rolled. If the material is welded then its probably normalized steel (possibly annealed but less likely). Cold rolling increases the yield strength of the material so less of it is needed. However, it also make the material more brittle. Welding creates defects in the region surrounding the weld and these are more likely to grow and cause failure in a cold rolled steel than a normalised or annealed steels. In addition the heat from the welding will change the microstructure that was deliberately introduced by the cold rolling process resulting in a localised drop in yield strength. Normalised and annealed steels are more ductile and tougher than Cold rolled steel but they have a lower yield strength. Because they are tough and ductile they are less sensitive to crakcs and defects so welding won't lead to as big a reduction in strength. Another possible consideration is the environment they are used in. Steels exhibit a transition temperature (actually more like a range) where they go from behaving like a ductile material to a brittle material. A well known example of what this can cause are the Liberty ships in WW2 (Supply vessels from the US to the UK). These were made by welding together sheets of cold rolled steel to form one continuous Hull. Unfortuantely the transiton temperature of the steel taht was sued was around 4 degrees while the Baltic Ocean is about 0 degrees. As a result small cracks would grow and then when the reached a critical size they would tear through the ship at the speed of sound in the metal (1500m/s) and these massive cargo ships would literally snap like twigs. So, if the steel is being used somewhere really cold its unlikely to be Cold rolled too.

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: What really is the difference between stain-less steel and iron? I only know that iron is an element, and stain-less steel is an alloy...but what else is there?: Steel is an alloy composed of mainly iron and carbon. Pure iron is very rarely used anymore. Depend on the concentration of the carbon, you can get from wrought iron to high grade steel. For stainless steel, Chromium is added to the alloy to prevent rusting. Just go to wiki. you should be able to find a lot more about it

Q: I know that it is used for katanas and swords but what is it and is it good i am pretty sure that it is the process of the steel but can I have a little more information.: Damascus or Wootz was a type of steel that appeared around 300BC It originated in India before spreading throughout Asia and the Middle East. It was considered a good steel, and for it's date of origin, exceptionally advanced for the level of technology in the ancient world. However the techniques to create the steel were lost forever after a decline in the swords manufacturing. The most popular theory is that the metal containing the required trace elements became less available over time due to unreliable trade routes. In the modern area, many scientists and metallurgists have studied the surviving blades, resulting in many discoveries such as evidence of carbon molecules fused in a crystalline structure. While the blades do provide some clues, it's only a small part of a much bigger picture as to the full process of the metal from raw to finished product. Now many have claimed to have recreated Damascus/Wootz steel, but none are recognised as being authentic. It has become a market ploy these days that draws people to purchasing the blades but all you are actually seeing is one of the many various forms of folded or patterned steel, which has varying degrees of quality, strength etc. We do know the steel was folded similar to the way the Japanese did in creation of old Katana, so often people will sell Damascus steel Katana that are nothing but folded steel swords like others. (Which is beautiful and traditional, but was a process designed to uniform impurities in the metal, something we no longer need to do with modern metals)
