Product Description:

Prepainted Galvanized Steel Coil for Building Decoration

Hot-dip galvanized steel coils are available with a pure zinc coating through the hot-dip galvanizing process. It offers the economy, strength and formability of steel combined with the corrosion resistance of zinc. The hot-dip process is the process by which steel gets coated in layers of zinc to protect against rust. It is especially useful for countless outdoor and industrial applications. Production of cold formed corrugated sheets and profiles for roofing, cladding, decking, tiles, sandwich walls, rainwater protective systems, air conditioning duct as well as electrical appliances and engineering.

Q:Engineering Materials - tool steel question?
It all depends what the application actually is. For hammers I would select a hammer grade B1 steel. For impact loading where an edge is needed I would be going for O1 or similar (oil quenching steels tend to be a little tougher than air hardening). For mining tools a very high manganese steel (Hadfields steel) - this is not a true tool steel. The best place to start is by looking at the ranking of the properties which you want - hardness v toughness v strength - and then use this to put the steels in rank order. Price and availablity then sort the problem out for you (in the real world).
Q:Steel toe boots safe?
I have been wearing Brahma brand steel toe work boots for the past 10 years (no, not the same pair for 1o years.. Each pair last me 2-4 years). They have ANSI class 75 steel toes. I work with cars, engines, tools all day long.. In the last 10 years I have had a transmission fall on my foot from about 2 feet high.. A bare cast iron engine block (153 lbs) break the bolts holding it to an engine stand and land on both of my feet. A camaro back over my foot with it's left rear wheel. Non of those things even dented the steel toe.. Just cut the leather covering the steel. No harm at all was done to my toes/feet. With out the steel toe boots, I know my toes/feet would have been broken.. 10 years so far, and from my results I plan on wearing steel toe boots for atleast another 30 years.

Q:Steel String for Classical?
If the guitar was designed for nylon strings, then don't put steel strings on it!
Q:Can you leave steel paintless?
There is another thing you can do to inhibit corrosion on bare metal surfaces. Use a good quality automotive wax. Apply it with diligence, and keep the bike in the garage when you're not using it so it stays dry. Touch up the wax job every now and then to maintain the protective finnish.
Q:Is boron steel harder?
The only thing that affects the hardness of steel is the carbon content. But there are many elements that can make it easier for a steel to achieve its maximum hardness. And Boron is an extremely effective element that increases the hardenability of steel. Adding as little as 0.002% Boron can have a big impact upon quenching of a steel. Boron is usually added when you need the hardness of a heat treated steel part to extend deep below the surface. For example, lets say you had a two identical plain carbon steel parts, but one had boron and the other didnt, and you wanted to heat treat them both After quenching, the surface should be the same on both, and lets say its 55 Rockwell C. In the plain carbon one, the hardness might drop down to 50 at 2mm under the surface, but the boron treated one might not drop to 50 until 4mm under the surface. Now, these numbers were completely made up, and it would depend on the specifics as to what the difference might be.
