Why Heavy Industries Choose Hot Rolled Stainless Plate (No.1 Finish)

When it comes to structural integrity and high load-bearing capacity, Hot Rolled Stainless Steel Plate (No.1 Finish) is the ultimate solution. Produced through a high-temperature hot rolling process, this material offers exceptional toughness, durability, and impact resistance.

The surface is treated with an annealing and pickling process, resulting in a dull, greyish, and slightly rough texture. Because the surface is clean and free of mill scale, engineers and fabricators can proceed to welding and assembly immediately. It is highly recommended for chemical storage tanks, pressure vessels, and heavy machinery frames where mechanical strength outweighs aesthetic appeal.

Frequently Asked Questions (FAQ)

No.1 finish plate (often referred to as matte or dull plate) is a thick stainless steel plate (typically 3.0mm and above). It undergoes hot rolling followed by annealing and pickling. The surface is dull grey and rough, engineered primarily for exceptional toughness and structural integrity in heavy industries, rather than for aesthetic purposes.

Trinity Dynamic supplies a wide range of grades compliant with ASTM A240 standards. We offer Grade 304/304L for general structural applications, Grade 316/316L for environments exposed to harsh chemicals or marine conditions, and the specialized Grade 310S for extreme high-temperature environments.

We maintain a robust inventory starting from 3.0mm up to 50.0mm+ in thickness. Our standard plate dimensions are 4x8 ft, 5x10 ft, and 5x20 ft. Additionally, we offer custom 'Cut-to-Size' services to meet your exact specifications.

Yes, absolutely! We operate as a full-scale steel service center. For thick plates, we utilize advanced CNC Plasma and Laser cutting machines. We can precisely cut circles, flanges, holes, or complex custom profiles exactly according to your engineering drawings, ready for immediate assembly.

If your project involves general structural work without exposure to severe corrosive agents, Grade 304 is highly sufficient and cost-effective. However, if the fabrication will be exposed to seawater, acids, or high chloride levels, Grade 316L is mandatory due to its added molybdenum content, which provides superior localized corrosion resistance.

Grade 310S is a highly alloyed austenitic stainless steel (containing 25% Chromium and 20% Nickel) designed for excellent oxidation resistance. It can withstand continuous temperatures up to 1,100°C (2,012°F). It is widely used for industrial furnaces, kilns, heat treatment fixtures, and high-heat petrochemical components.

Yes. Every stainless steel plate supplied by Trinity Dynamic is accompanied by a Mill Test Certificate (MTC) to guarantee its chemical and mechanical specifications. We also provide comprehensive logistics and transportation services directly to your factory or construction site anywhere in Thailand.
