Stainless Steel Chequered Sheets and Plates are robust, anti-slip materials that find extensive use in both industrial and architectural settings. Manufactured and supplied by reputable companies in Bangkok, Thailand, these sheets showcase a raised diamond or tear-drop pattern on one side, which significantly boosts grip and slip resistance. They come in a variety of stainless steel grades such as 304, 316, and 409, ensuring top-notch corrosion resistance, durability, and a pleasing aesthetic. With their precise thickness, consistent pattern, and polished finish, stainless steel chequered sheets and plates not only serve practical purposes but also enhance visual appeal, making them ideal for flooring, cladding, and safety-critical applications.
Typically, Stainless Steel Chequered Sheets and Plates are crafted from grades like SS 304, SS 316, and SS 409, each with its unique composition. Grade 304 consists of around 18% chromium and 8% nickel, providing excellent corrosion resistance and formability. Grade 316, on the other hand, includes molybdenum, which enhances its resistance to chlorides and acids. These materials boast a tensile strength ranging from 500 to 750 MPa, a yield strength of 200 to 500 MPa, and an elongation of up to 40%, depending on the grade. The raised chequered pattern doesn’t compromise mechanical strength; instead, it enhances functionality by improving slip resistance and wear durability in high-traffic environments.
