Steel and Iron - Steel Chequered Plates
Summry
Steel chequered plates are flat steel sheets with raised patterns (diamond or checkered shapes) on the surface. They provide better grip and slip resistance, making them ideal for industrial flooring, staircases, ramps, trucks, and heavy machinery areas. They are strong, durable, and resistant to wear and tear.
Why BIS Certificate is Mandatory for Steel Chequered Plates ?
BIS certification is mandatory for steel chequered plates to ensure quality, strength, and safety standards. It verifies that plates meet prescribed chemical composition, mechanical strength, and dimensional tolerances. Certification prevents substandard products that could fail under load, ensuring structural safety and compliance with Indian standards for industrial applications.
What is BIS Certified for Steel Chequered Plates ?
The BIS certified specification for steel chequered plates is IS 3502 (Part 1/Part 2) – Mild Steel Chequered Plates. It defines requirements for material composition, thickness, pattern height, mechanical properties, and workmanship. Compliance ensures plates are safe, durable, corrosion-resistant, and suitable for industrial and commercial applications.
