MS PLATES
Mild Steel (MS) Plate is a steel plate used for construction. It is flexible, not brittle and it is the most common form of steel.
MS plates are used to give strength to a concrete cement in a building or any structural works. It is also used for construction and industrial applications.

Galvanized Iron Sheets ( GI SHEETS)

Galvanized iron (GI) sheets are basically steel sheets which have been coated with zinc. These sheets include a range of hot dip galvanized and electro-galvanized steel sheet. The zinc coating provides a continuous barrier which does not allow moisture and oxygen to reach the steel. It reacts with the atmosphere to provide the base steel a protection.

By galvanizing, the protection of the steel sheets against corrosion resistance is improved by several degrees of magnitude. The corrosion protection achieved by zinc-based coatings is as a result of the galvanic effect, since zinc is anodic to iron which makes it act a sacrificial metal in an aqueous or humid environment. However, resistance to surface degeneration can be further enhanced by the incorporation of top coat on the galvanized surface. Galvanized steel sheets are also known for excellent shiny surface and formability attributes besides satisfactory peel-off resistance and fusing of the coating completely to the steel surface.

Zinc weathers at a very slow rate, so the coating normally has a long life. Zinc has a greater electro-negativity than iron and hence provides cathodic (or sacrificial) protection to the steel

SS PLATES
Stainless steel plate is often referred to as ‘corrosion-resistant steel’ – it does not stain, corrode or rust as easily as normal carbon steel. … Due to its anti-oxidation qualities, stainless steel is often a popular solution.

GRADE 70 PLATES
ASTM A516 Grade 70 Plate is also called out as ASME SA516-70. This steel plate grade is a medium carbon alloy that also contains amounts of manganese, phosphorus, sulfur, and silicon.
A516 is primarily used for service in welded pressure vessels where improved notch toughness is required.

GRADE 60 PLATES
ASTM A516 Grade 60 Plate is a carbon steel plate that is made up of carbon, silicon, manganese, phosphorus, sulfur, aluminum, chromium, copper, nickel, molybdenum, niobium, titanium and vanadium in the composition.
These plates are very strong. They have 265MPa minimum yield strength and up to 580MPa minimum tensile strength.
These are intended for use in medium temperature applications where the pressure is high.
The ASME SA 516 Gr.60 Plate is used in different sizes. The thickness ranges up to 150mm, the width ranges up to 3.5m and the length can range up to 12m in production. Cut to lengths are also available.

GRADE 50 PLATES
Grade 50 is a high strength, low alloy steel that finds its best application where there is need for more strength per unit of weight. Less of this material is needed to fulfill given strength requirements than is necessary with regular carbon steels.
Grade 50 is used in general plate applications when the plate will be riveted, bolted, or welded.
Grade 50 is a Columbium-Vanadium steel that offers a minimum yield of 50,000 PSI. In addition, ASTM A572 Grade 50 is noted for its increased resistance to atmospheric corrosion.
Grade 50 contains more alloying elements than plain carbon steel and thus is somewhat more difficult to form. Grade 50 is more difficult to cold work, but can be successfully bent or shaped but requires more force than plain carbon steel.
