Stainless steel finishes are often utilized in applications where hygiene, durability, and a high-quality appearance are essential, such as in the food and beverage industry. 6. Cold-rolled: This finish involves passing the steel coil through a series of rollers at room temperature, resulting in a smooth, polished surface. Cold-rolled finishes offer improved dimensional accuracy, surface quality, and flatness, making them suitable for applications that require tight tolerances and a refined appearance. 7. Metallic coated: This finish involves applying a layer of a metallic coating, such as aluminum or zinc-aluminum alloy, onto the steel coil. Metallic coated finishes offer excellent corrosion resistance, lightweight properties, and aesthetic versatility. Overall, the choice of finish for steel coils depends on the specific requirements of the application, considering factors such as corrosion resistance, aesthetics, durability, and cost-effectiveness. It is important to consult with industry experts and manufacturers to determine the most suitable finish for a particular project.

Q: A song by brokencyde is called Blue Steel.... a verse in it says Don't make me show you blue steel.: Actually, it is a reference to the movie Zoolander, which is a comedy. Ben Stiller's character (Zoolander) is a fashion model (and assassin) and he gives names to the poses he takes in front of the camera. One of the poses, which nobody can supposedly resist, is called Blue Steel. Although bluing is something that actually is done to gun metal to harden it (i.e. heating/plating with nickel), that is not what this particular song is referring to.

Q: I want to purchase steel for construction purpose, What aspects should I keep in mind while deciding that which company should I contact for this?: It has been a few years since I was in the business but I have found that some steel from some countries can be quite different from the standards steel made in the US. For instance, one in 5 of my Indian made cast iron fittings would break when tightening it down. This never happened with US fittings. Even though I could take it back and get a refund, the increased price of US made materials was worth the savings in time and trouble. On a job in Columbia, the 3 inch angle iron came to us in 4 different sizes, all around three inches but not quite. This is not to say that all foreign metal is bad. One RD project I headed up we found a foreign bearing steel to be far superior to anything we could get in the states.

Q: I heard that titanium isn't the most hypoallergenic metal because it is treated and the chemicals can cause an allergic reaction. I also heard that surgical steel is the best because it is what is used in surgery and in hip replacement implants etc. Is this correct?I've always heard that titanium is best, but now I'm curious because surgical steel is much cheaper than titanium which can be expensive.Thanks: Implant grade titanium is much better than surgical steel. The nickel content in it (which is what alot of people are allergic to) is virtually non-existant. Though most people with a nickel allergy are fine with surgical steel too, its too small for most people to react to. But the odd few people do. Its the same with everything. Good surgical steel is probably better than cheap titanium. But implant grade ti will beat it hands down. And ti is alot stronger, and is also used in surgical impants and as replacement bits too. But a big lump of titanium hip is going to be expensive. If you're not allergic to steel, theres little reason for the extra cost, especially if it's likely to outlive you. Niobium has no nickel in at all. But that really is expensive, and I've never seen any threaded. Any particular reason why you ask? ----- Piercing-wise titanium will be better than steel. Unless they carry some not so great ti. You should be fine with steel though.
