Chhajed Steel Limited is one of the most prominent names involved in trading and supplying R355 and 537CL.1 ESSAR plates. These plates, exclusively manufactured at Chhajed Steel Limited, are made available to clients at highly competitive prices. These plates meet the highest standards of quality and performance by using premium-quality raw materials and the finest grades of steel. It is due to their versatility that such plates are ideal for various purposes in the gas industry and pressure vessel construction.
The advanced features of these plates have made them a very valuable commodity in various sectors. They are designed to give out high friction, which allows for maximum skid resistance, and have high ductility that can be shaped and sized easily. The base material, when in mill-edge condition, can be further improved for use in specialised applications.

Benefits:-
R355 and A537CL.1 ESSAR plates are produced using the latest technology from Germany and Japan at the state-of-the-art mills of Chhajed Steel Limited, thus ensuring high standards of quality. The plates are supplied to resellers in various conditions, such as quenched and tempered, rolled, normalised roll, thermo-mechanically controlled rolled, furnace normalised, and shot blast and primer coated. The advantages of steel plates by Essar incorporate numerous dimensions and thicknesses at various widths. There can be, with the desired dimensions of the plate, fewer joints. A firm, bright surface with a clean texture adds to their aesthetic value. It develops excellent corrosion resistance and high pressure resistance against toxic chemicals. Better tensile and yield strength allow it to stretch and be compressed without losing integrity. Besides, even at high temperatures, they could still maintain their mechanical properties, thus having great heat resistance.
