Types of Steel Plate

Galvanised steel plates

Just like galvanised steel coils, galvanised steel plates are coated with zinc. It is made by immersing steel into molten zinc. The zinc coating offers steel strength and corrosion resistance.

Mild steel plates

Mild steel plates also known as MS plates are one of the most common steel plates used in construction. These plates have gained popularity due to its versatility.

Checkered steel plates

Checkered steel plates can easily be recognised by its raised surface in the design of checkers. These plates are widely used in flooring.

Black iron (BI) plates

Black iron plates are manufactured from mild steel and have low carbon content. It mainly contains aluminium and copper.

Galvanised iron (GI) plates

Galvanised iron plates are different from galvanised steel plates. Usually, galvanised iron is iron that has undergone galvanisation treatment. Iron is submerged into molten zinc and is applied with zinc coating.

Surface Treatment of Steel Plate

Zinc phosphate priming

Steel surfaces can be painted with specially formulated primers in order to improve corrosion resistance as well as boost their visual appeal, with one of the most popular applications being zinc phosphate priming. Zinc phosphate is an inorganic chemical compound that can provide active or inhibitive corrosion resistance to low-alloy and carbon steel and zinc primer has been used in everything from construction to ship building to the automotive industry.

Chemical coating

The power coating, or chemical coating, technique uses electrostatic or compressed air to apply a specially formulated powdered material to the steel surface, following which it is melted to form a smooth protective film. Steel treated in this way is not only protected against corrosion and UV damage, it is also highly resistant to peeling, scratching and cracking. Because powdered chemical coatings have no liquid component thicker protective coatings can be applied and they also tend to emit fewer volatile organic compounds.

Hot dipping

This galvanization method can be used on steel of all shapes and sizes and involves immersing the steel in a bath of molten zinc at temperatures up to 450°C. When the zinc coated steel is removed from the bath, the zinc reacts with the oxygen and carbon dioxide in the atmosphere, the end result being a strong, dull material. Steel has been hot dipped in this way is highly protected against corrosion as well as extreme weather conditions and this is a particularly popular approach for pipe related applications.

Zinc spray metallizing

While it doesn’t provide quite the same protection as hot dip galvanising, the zinc spray metallising technique is highly effective against corrosion and is popular for its smooth finish. First the steel is shot blasted to create a roughened surface then the zinc spray is applied almost immediately, resulting in a solid bond being formed between the zinc and the steel. Because this is a ‘cold process’ there is no risk of distorting the metal, making it ideal for use on ornate metal components such as railings and fences.

Steps for Inspecting Steel Plates

Quantity and packing condition
The inspection begins with a quantity verification, checking the consistency with the purchase order, as well as examining the packing condition, including labelling accuracy and proper protection for transportation to prevent any damage during transit.

Visual inspection
The inspector will evaluate the products’ appearance at random using visual inspection, seeking any defects such as surface imperfections, scratches, or inconsistencies in finish. They also verify if there’s any identification information on the steel plates’ surface.

Dimension verification
The inspector employs calipers or a ruler for physical dimension verification, comparing the dimensions against the specified requirements and tolerances.

Witnessed chemical analysis
Another standard parameter is ensuring the stainless steel aligns with the specified requirements and industry standards. This verification is typically achieved by witnessing the factory’s chemical analysis. The inspector observes the entire process, from the sampling of the stainless steel material to the actual testing and analysis.

Document review
Last but certainly not least, the inspector reviews the provided documentation, including the material test certificate, certifications and standards compliance, and other relevant documents.

Application of Steel Plate

Construction
Steel plates play a versatile role in the construction industry. They’re particularly common in the construction of bridges, building, and warehouses. They’re also used for building large commercial structures like airports and sports arenas.

Military
Military buildings and vehicles are often fortified with the help of steel plates. They’re common in jeeps, tanks, trucks, helicopters, jets, and ships used for military purposes. They’re also used to test the strength of weapons and bullets. All branches of the military use steel plates in some fashion.

Ship construction
Easily welded and ultra-strong, steel plates are used in a significant number of ships and are probably one of the most commonly used materials in ship building. They’re also a key component of many oil rigs and in offshore construction. Their corrosion resistance makes them ideal for these applications.

Pressure vessels
Pressure vessels like gas tanks and boilers, which need to protect against leaks and extreme temperatures, are frequently made of steel plates. Oftentimes, these steel plates are specifically engineered to be able to hold gas or fluid contents at different temperatures to reduce the risk of explosion.

Shipping
Large shipping containers are commonly built using steel plates. Steel plates help preserve the life of these shipping containers due to their corrosion and rust resistance, and they are strong enough to protect all different types of cargo.

Oil and gas
In addition to being used for construction of rigs, many oil and gas pipelines use steel plates to maximize their strength and ensure they last longer without corroding. Steel plates can easily be welded to suit the needs of pipelines and can also be used for repair purposes when parts of pipelines need to be patched up.

Products Description

Q: What is steel plating used for?

A: Both this method and others are designed to enhance the metal's resistance to corrosion, each offering various benefits. While metal plating can protect a part or component from environmental damage, it also enhances its appearance. There are various types of coatings, categorized as either industrial or commercial.

Q: What is the function of steel plate?

A: Steel Plate is commonly used to strengthen foundations and uphold mass units of weight like bridges. Alternatively, it provides a base for construction of larger materials and non-workable parts. Applications for Steel Plate are based acutely on the specifics of the project.

Q: How long do steel plates last?

A: The replacement frequency depends on factors such as material, level of protection, and usage. As a general rule, steel plates can last up to 20 years, while ceramic plates should be replaced every 5-7 years. Always follow the manufacturer's recommendations and inspect plates regularly for signs of wear and tear.

Q: Where is steel plate used?

A: Steel plates are used in bridges, buildings, and warehouses. They are also used for the projects of large commercial structures such as airports, prefabricated buildings, warehouses, railway stations, and sports centers. In addition, steel plates are used to strengthen building foundations.

Q: How thick should a steel plate be?

A: Steel sheets are thinner than plates and typically measure from 0.5 mm to 6 mm. Anything thicker than 6 mm is considered plate.

Q: How to test a steel plate?

A: Tensile tests in the thickness direction or “Z tests” are performed to evaluate the mechanical properties of steel in the thickness direction of a plate. The test involves the application of tensile forces on a test sample, with the axis of the test sample perpendicular to the rolling direction of the steel plate.

Q: What is the standard test for steel?

A: The tensile strength test is one of the most common tests used to evaluate the quality of a material. This test determines the maximum load that a material can withstand before it breaks or deforms permanently. To perform this test, a sample of the material is stretched until it reaches its breaking point.

Q: What is the hardness test of steel plate?

A: The Brinell hardness test method consists of indenting the test material with a 10 mm diameter hardened steel or carbide ball subjected to a load of 3000 kg. For softer materials the load can be reduced to 1500 kg or 500 kg to avoid excessive indentation.
