Clad Steel Plates can solve almost any problem designers face when working in demanding industries such as construction and chemical processing.
Cladding Plate is more corrosion-resistant steel and a stronger, less costly metal to produce. But before we discuss the benefits of using clad steel, let's get a clear definition.
Clad Steel Plate
There are various processes for carbon steel cladding, such as hot rolled bonding, cold-rolled bonding, explosion bonding, brazing, welded cladding, weld overlay, and centrifugal casting. Hot-rolled bonding is the process generally used. In this process, clean sheets of carbon steel and stainless steel are placed together, (single-sided cladding), or sandwiched between two stainless steel sheets (double-sided cladding). The laminates are hot rolled together.
The stainless steel cladding process results in a bond between the two metals. Another manufacturing method includes explosive bonding. This bonding is produced by the plastic deformation of the metals due to the strong collision during the explosive bonding process. Sometimes, the explosive bonding is followed by a hot rolling process to improve the bond between the carbon steel and the stainless steel.
Clad carbon steel is used in various applications such as chemical processes, petroleum refining, offshore oil production, etc. It is also used in power generation installations, where there are high temperatures and stress corrosion.
Clad steel sheets are classified as composite steels and are created by bonding two or more metals together. Typical cladding materials on steel sheets include stainless steel, nickel, copper, high nickel alloys and copper-nickel alloys. Cladding allows you to combine the properties of each metal to produce a better, higher-performance product.

Clad Steel Plate
Cladding materials offer tremendous benefits for heavy industry and chemical processing. Depending on the combination of cladding materials, cladding can produce superior strength at a lighter weight and lower cost. It can also create excellent thermal and electrical conductivity or corrosion resistance. As a result, clad plates are often used in extreme wear situations such as mining, excavation, processing, and pumping, as well as in paper, pulp, and food processing.
Not only are clad plates incredibly durable, but they offer tremendous manufacturing advantages. Surfaced plates can be cut and formed, including plasma cutting, drawing, bending, and thermoforming, however, it is very difficult to punch, drill or machine.
As mentioned above, a clad plate is produced by bonding two or more metals together to form a single sheet or plate. Depending on the specific requirements, various cladding or backing materials, such as specialty metals, such as copper or stainless steel, can be rolled or fused to a base metal, such as carbon or low alloy steel, to produce a metallurgically bonded cladding.
While there are different processes, the most common is probably roll bonding. To produce a rolled laminate, the two joined surfaces are first cleaned and placed in contact. The edges of the sheet are then welded to prevent movement and air ingress during the hot rolling stage. After cutting to the final size, the laminate is cleaned to produce a relatively bright surface.

Buying the right coaxial cable can be confusing! You have different &#;RG&#; designations, multiple shielded variations, and even different outer sheath (cable jacket) options. Adding to the confusion are two different center conductor types. In sorting through this confusion, we will address an age-old debate as to whether you should opt for solid copper center conductor coaxial cable, or if CCS or copper clad steel is &#;good enough&#;. Keep reading to learn about the difference between solid copper and copper clad steel.
Coaxial cable has been provided in two primary center conductors types for some time:
Copper clad steel (CCS)
Solid copper (BC or bare copper)
Let&#;s look at an illustration of how coaxial cable is constructed to give you a better idea of what part of the cable we are talking about:
Contact us to discuss your requirements of buy copper clad steel plate. Our experienced sales team can help you identify the options that best suit your needs.
Perhaps the standards setting organizations like ANSI/TIA, SCTE, or some other organization will help clarify which one is better?
The ANSI/SCTE 74 specification allows for either one to be used.
No help there.
The ANSI/TIA 568.4-D BroadBand Coaxial Cable and Components standard makes no distinction between the two in regards to performance.
Still, no joy.
The ANSI/TIA 568.0-E Generic Telecom Cabling Standard only separates the two in regards to the amount of pulling tension that can be applied to the cable while installing it. The specification states copper clad steel may have up to 75 ft/lbs applied and 40 ft/lbs is tops for solid copper.
Helpful, but still coming up short!
So, what will it take to get the answer!? In truth, the answer is &#;yes, kind of&#;.&#; Confused yet? Let&#;s untangle the difference between solid copper RG6 and copper-clad steel before people start popping anti-anxiety meds.
Coaxial cable constructed of copper clad steel relies on what is known as the &#;skinning effect&#;. In other words, the signal travels down the copper coating to the destination and it is perfectly fine for data transmission. There is no measurable loss in data transmission between copper clad steel and solid copper center conductor coaxial cable. As long as the copper coating over the steel remains intact, all is good.
Where solid copper coax cable really puts copper clad steel to shame is when it comes to cable runs requiring voltage. Now, we don&#;t mean AC voltage here. We are referring to low DC voltage for powering up a satellite dish, for example. In fact, RG6 CCS cable will lose TWICE as much voltage over the same distance as RG6 solid copper coax cable. Finally, we see a big difference between the two! This is why satellite installers and satellite system designers require solid copper coaxial cable. Satellite dishes and receivers use a LNB (Low-Noise Block downconverter) that requires power across the coaxial cable.
Considering you may be installing coaxial cable in multiple environments, it makes little sense to stock and keep track of both. A simple mistake of grabbing the wrong spool will bring your install to a halt if you have to backtrack to the shop to get the right cable. There is also the possibility of the future to consider: What if down the line someone needs to install some sort of power injector onto that coaxial cable? If you used copper clad steel, you just caused yourself a replacement or an angry end customer. If you install for a living, be prepared to educate your end customers about this.
Both CCS cables and solid copper ones have the same maximum run distance. Solid copper does not get you more length.
Both CCS and solid copper have the same data transmission characteristics, so solid copper does not get you more bandwidth
CCS cables are less expensive than solid copper
CCS can withstand more pull tension during installation than solid copper, but realistically not enough to make a purchasing decision. The upper limit of 40 ft/lbs maximum pull tension for solid copper is more than enough.
Solid copper coaxial is far superior for applications requiring voltage to a device
Solid copper is strongly recommended for satellite installations
Solid copper is the better choice for A/V (audio/visual) applications
CCS can and will destroy cable cutters. Many cable cutters designed for low voltage communications cable (like Ethernet for example) use thin razor blades to do the cutting part. A thin razor blade will end up royally wrecked if you try to cut CCS with it. CCS requires durable cable cutters with hardened steel jaws for the task.
DO NOT under any circumstances attempt and cut copper clad steel with our Cable Cutting and Stripping Tool! Instead, use cutters such as the trueCABLE Heavy Duty Cable Cutters."
Do not confuse CCS for CCA. Copper clad steel is &#;OK&#; to use for coaxial cable per the standards organizations, assuming you are installing it in the right environment. CCA or copper clad aluminum is not suitable for communications cable under any circumstances. See more on CCA in Copper Clad Aluminum vs Copper: The Ultimate Test on a Fluke Versiv DSX CableAnalyzer.
So, in the final analysis yes you can save a couple of bucks buying copper clad steel vs. copper coax but in the long run it is not worth it. trueCABLE recommends purchasing and sticking with solid copper center conductor coaxial cable.
