Product Description:

Cold rolled steel coil/sheet is one of the main raw material of furniture automotive parts, industry steel parts, building construction, 

raw material of color painted coil. Meanwhile we can provide full hard raw material they are properly used in the high strength 


Because cold rolled steel sheet is prone to rusting, standard practice is to apply a rust-preventative oil at the exit end of the temper mill (the last processing step). Rust-preventative oils are different than forming lubricants in that they contain special corrosion-inhibiting additions. In addition to the oil, Curtis Steel maintains clean, dry environments in climate controlled warehouses at 

all its facilities to ensure our coils and sheets arrive to you in prime condition.

Q:Why does stainless steel get rusty?
Stainless steel is manufactured in a variety of different alloys. The percent of Chrome and other metals determine which alloy of stainless is produced. Not all versions of stainless is rust proof, just rust resistant. Not knowing which version of stainless steel you are discussing makes an exact answer difficult. Most stainless steel needs also be exposed to oxygen to retain it's 'stainless' properties. There are also version of steel, Monel and Inconel, that most would consider 'stainless'. Salt water will rapidly affect most versions of stainless with what is called cloride stress corrosion which cause a failure of the lattice structure of the metal. Generally, some stainless steel with a lower chrome content may appear to have discoloration that appears to be rust.
Q:Steel or Iron? (stupid 20 characters thing)?
steel is harder than iron Iron is a chemical element. It is a strong, hard, heavy gray metal. It is found in meteorites. Iron is also found combined in many mineral compounds in the earth's crust. Iron rusts easily and can be magnetized and is strongly attracted to magnets. It is used to make many things such as gates and railings. Iron is also used to make steel, an even harder and tougher metal compound. Steel is formed by treating molten (melted) iron with intense heat and mixing it (alloying) with carbon. Steel is used to make machines, cars, tools, knives, and many other things.
Q:Where do I need hot galvanized steel coils and color coated rolls?
The use of galvanized steel for color coated steel substrates, except zinc protection, organic coating on the zinc layer up covering the isolation effect, can prevent rusting steel, galvanized steel service life is longer, the coating steel plate galvanized steel long service life is 50%. However, the service life of the color coated plate with the same amount of zinc coating, the same coating and the same coating thickness will vary greatly in different regions and different parts.
Q:stainless steel properties??
Stainless steel is a generic term for a whole range (there are more than 60 types) of Fe-Cr alloys. They all contain some amount of C and some alloys include a good number of other alloying elements. In almost all cases, the materials have corrosion resistance due the Cr atoms that are in solid solution with the Fe matrix. Under corrosive conditions, the Cr forms a thin tight coherent layer of Cr-oxide. This Cr oxide coating prevents further corrosion so long as it is not chemically or physically removed. If the SS has been subject to mechanical abrasion, the corrosion resistance can sometimes be restored by a light exposure to nitric acid which passivates the surface, restoring the Cr-oxide layer. The carbon content is an important factor in corrosion preformance but so is the heat treatment. Under the wrong conditions and in different environments, all SSs can rust. One of the most common corrosion problems is sensitization which occurs in the heat affect zone (HAZ) around welds. If the C content is high enough and the heat is high enough, the Cr atoms in solid solution form Cr-carbides and are no longer available to form a protective Cr-oxide. The corrosion resistance can be restored by appropriate heat treatment.
Q:aluminum vs. steel?
You would think that is the case, right? Well, it isn't. Steel rims are necessarily made of very thin sheet. This sheet, when formed into a rim tends to dent very easily. On top of that, because the material is so thin it can and does flex- a lot. Aluminum rims on the other hand are formed by a process called extrusion... basically, a big block of material is shoved through a die (think PlayDoh shape maker) and then formed into rims. This forming process along with the stiffer nature of aluminum (in this instance) makes an aluminum rim far stronger and far lighter than a steel counterpart.
Q:whats the difference between weld steel and sheet metal?
Gauge is a measure of thickness. 19 Ga = 0.0418 20 Ga = 0.0359 22 Ga = 0.0299 Higher numbers are obviously thinner sheets. To my knowledge the way it works is going up five gauges means the thickness is reduced by half. For example 10 Ga. is 0.1345 in, while 15 Ga is 0.0673 in.
Q:Can you give me the general working and description of a steel cooling bed?
In the USA, a steel cooling bed is called a run-out table. It consists of a series of steel rolls. Each roll may be individually driven by an electric motor. DC motors are often used with parallel armatures connected to a common armature voltage control speed control unit. The roll speed is controlled to match the speed of the incoming sheet of steel so that the steel does not slide or skid on the surface of the rolls. Field trim resistors help to assure that the speed and torque of rolls is matched. A centering mechanism may be used to keep the steel in the center of the table. Water may be sprayed from the top and bottom to aid cooling. After an initial run out table, the strip of steel may be cut on-the-fly into individual sheets which pass to another table that is running slightly faster to separate the sheets. Alternatively, the steel may be coiled at the end of the table.
