Clad Steel Plate

Clad Steel Plates,also called Roll-bonded plates, are our answer to the issue of corrosion resistance. GNEE STEEL are a world leader in roll-bonded plates.

 

GNEE STEEL, the world's leading manufacturer of roll-bonded clad plates,offer clad plates, clad heads and clad cones from a single source.
As a manufacturer with several decades of experience in roll bonding, we are your reliable partner in the linepipe, pressure vessel and apparatus industry. We understand our customers, provide the quality they need and have a large capacity to produce roll-bonded clad plates.

 

What is Clad Steel Plate?

 

Clad plate is a multi-layer plate which combines a carbon or low alloy steel plate (backing or backer) with a thin layer of corrosion resistant grade (cladding or clad).

 

Clad steel plate, which are based on carbon structural steels, low alloy high strength structural steels or high strength quenched andtempered steels as the base plate, single or both sides combined with stainless steel, special steel, etc. in a certain degree through the clad rolling technology, to produce the clad steel plates.

 

This base material-cladding material combined mode, realizes different kinds of steel material properties blending into one. In the use of functions, both the base plate strength as a structural component meets the requires of customers' machining and processing performance, and the cladding material with excellent corrosion resistance, wear resistance, high strength are obtained. Moreover, clad steel plates, compared to the original single cladding plate production, have substitution and high cost performance. Therefore, clad steel plates is a more economical and efficient Cladding product.
