Product Description
Our Galvanized Steel Sheets (GI) are high-quality, versatile flat-rolled steel products coated with a layer of zinc for excellent corrosion resistance. Produced in compliance with international standards such as SASO ASTM A653M, these sheets are designed to provide superior durability and a long service life, making them a preferred choice for a wide array of construction, manufacturing, and industrial applications.
The zinc coating, applied through a hot-dip galvanizing process, protects the base steel from rust, making it ideal for both indoor and outdoor use. We offer a comprehensive range of sizes and thicknesses, with various zinc coating weights (e.g., G90, G60, G20) to meet specific project requirements for corrosion protection. The regular spangle finish is a classic, cost-effective choice for general applications. These sheets are easily formable, weldable, and paintable, providing a reliable and workable material for any project.
Steel sheet is offered in a couple of different ways:
Discrete Sheet
Hot rolled discrete sheet is produced on a reversing mill to its final length and width. The slab is passed back and forth through the mill to attain the desired thickness. This approach can achieve widths up to 120”, but its shape may be compromised in lighter thicknesses.
Sheet Cut from Coil
Hot rolled coils are made from cast slab produced on tandem mills where it is rolled continuously without reversing the direction. The coils are then either slit for stamping lines or can be cut to specific lengths (plates or sheets). This approach can typically achieve widths up to 96”. Coils typically offer improved surfaces and better shape.
Benefits of Steel Plate Cut from Coil
If your application doesn’t require the larger widths available with discrete plate, you might want to stop buying stock discrete plate sizes. At Yeson Steel, we can cut steel plate from our existing coil plate stock in customized lengths and widths up to 1” thick. The benefits of this plate from coil approach as compared to discrete steel plating methods are numerous:
•Eliminate Waste — Custom lengths allow you to maximize yield and reduce scrap
•Improve Aesthetics — Plate from coil has a smoother finish with less mill scale
•Lower Costs — Plate from coil typically offers a price advantage
•Reduce Inventory — Our warehouse capability helps eliminate inventory issues
Dimensions & Properties
Whether steel qualifies as plate or sheet depends on the specification used for certification. There is a large overlap in popular thicknesses between plate and sheet, but steel plates are offered in a much broader range of sizes.
Common plate specifications:
•ASTM A36: a very popular structural steel specification.
•ASTM A572 and A656: these specifications define HSLA (high-strength low-alloy) grades.
•There are also specifications written for specific applications such as weathering grades (A588, A606) for atmospheric corrosion resistance, floor plate steel (A786), and steel produced for bridge applications (A709).
•Plate specifications are not limited to ASTM; other governing bodies and OEMs write specifications for steel plate.
At Yeson Steel, our steel plate and plate cut from coil specifications include, but are not limited to ASTM, AMS, and Euronorms from 3/16” up to 12” thickness.
All projects are unique, which is why our engineers at Yeson Steel welcome specialty requests to make a custom steel plate to fit your specific applications.
Good corrosion resistance
prevents the steel plate from directly contacting the atmosphere, water, and other chemicals.
Strength and durability
It has steel’s impact and pressure resistance and is not easy to deform.
Easy to process and install
can be cut, bent, and welded, and it is easy to install, use, and maintain.
Good decorative properties
The surface is shiny and smooth, beautiful.
All Types of Galvanized Processes
According to the galvanizing process and coating material, Yeson Steel galvanized steel panels can be divided into three categories: hot-dip galvanized steel sheet, electro-galvanized steel sheet, and pre-painted galvanized steel panels.
