What Is Stainless Steel Plate?

Stainless steel plate is a thick, high-strength flat metal product made from chromium-nickel alloy steel, designed to withstand extreme loads, corrosion, high temperatures, and harsh industrial environments. Unlike thin stainless steel sheets, stainless steel plate typically starts at 3mm in thickness and can reach over 100mm for heavy structural applications, offering superior strength and durability.

As a core raw material for our heavy-duty expanded metal production, stainless steel plate ensures the final products maintain structural integrity and corrosion resistance in the most demanding conditions. The quality of the base plate directly determines the performance, lifespan, and load-bearing capacity of our fabricated metal mesh components.

We source only premium hot-rolled and cold-rolled stainless steel plate from certified steel mills, ensuring full compliance with ASTM, EN, and JIS international standards. Our strict material selection process has made us a trusted global expanded metal mesh facade supplier for commercial and industrial projects worldwide.

Key Grades of Stainless Steel Plate

We supply stainless steel plate in the most widely used industrial grades, each engineered to deliver specific performance characteristics for different environmental and operational requirements. Choosing the right grade is critical to achieving optimal performance and cost efficiency for your project.

304 and 316 stainless steel plate are the most popular choices for our expanded metal and structural fabrication services. For coastal, marine, or chemical-exposed projects, we always recommend 316 grade for its exceptional resistance to saltwater and corrosive substances.

Thickness & Size Specifications of Stainless Steel Plate

We offer stainless steel plate in a full range of standard thicknesses and sizes, with custom cutting and profiling services available to meet your exact project requirements. Our CNC cutting equipment ensures precise dimensions and smooth edges for every plate we supply.

Standard Thickness Range

• 3mm – 10mm: Medium plate for fabrication and expanded metal
• 10mm – 30mm: Heavy plate for structural and industrial use
• 30mm – 100mm: Extra-heavy plate for large-scale engineering

Standard Plate Dimensions

Our custom cutting service eliminates material waste and reduces on-site processing time, making our stainless steel plate solutions highly efficient for large-scale fabrication and construction projects.

Surface Finishes for Stainless Steel Plate

The surface finish of stainless steel plate impacts corrosion resistance, aesthetics, and cleanability. We provide a variety of standard and custom finishes to match both functional and decorative requirements for industrial and architectural applications.

• No. 1 Finish: Hot-rolled, annealed, pickled – rough industrial surface for structural use
• 2B Finish: Cold-rolled, smooth, matte – standard for fabrication and expanded metal production
• Brushed Finish: Uniform directional lines – modern aesthetic for architectural facades
• Sandblasted Finish: Matte, non-reflective surface – ideal for industrial equipment
• Mirror Finish (8K): Polished high-gloss surface – decorative and architectural applications

The 2B finish is the standard choice for our custom expanded metal fabrication services, as it offers an ideal balance of formability, corrosion resistance, and visual appeal for both industrial and architectural use.

Manufacturing Process of Stainless Steel Plate

The production of high-quality stainless steel plate involves a series of precision manufacturing processes to ensure material purity, dimensional accuracy, and consistent mechanical properties. Every step is strictly controlled to meet international quality standards.

1. Precision smelting with controlled chromium, nickel, and molybdenum ratios
2. Continuous casting to form high-quality steel slabs
3. Hot rolling at high temperatures to reduce thickness and form plate profiles
4. Heat treatment and annealing to relieve internal stress
5. Cold rolling for precise thickness and smooth surface finish
6. Pickling and passivation to enhance corrosion resistance
7. Ultrasonic testing and quality inspection before shipment

We partner with top-tier steel mills that implement advanced quality control systems, ensuring every stainless steel plate we receive meets our strict requirements for strength, corrosion resistance, and dimensional accuracy.
