BIS Certificate Steel Chequered Plates – IS 3502 2009

Steel checker plates are known as popularly known plates or diamond plates, widely used in construction, flooring, shipbuilding and heavy industries due to their durability and anti-slip properties. In India, the manufacture or sale of these plates is regulated by the bureau of Indian standards (BIS) under the order of steel and steel products (quality control), making BIS certification mandatory.

This blog provides a complete informative guide for BIS Certificate Steel Chequered Plates – from applied standards to testing, documentation, procedure and profit.

What are Steel Chequered Plates?

Steel checker plates are hot-rated steel sheets, which have embossed patterns such as diamonds, losengs or lines on one side. These patterns provide better grip and slip resistance, making them suitable:

• Industrial floor and walking routes
• Rail coach and truck platform
• Ship deck and dock
• Ramp, Stairs and Parking Area
• Storage room, godown and machinery flooring

Their strong structure ensures strength, while the pattern surface increases security in high -risk working areas.

Why BIS Certification for Steel Chequered Plates is Mandatory?

The Government of India makes the BIS Certificate Steel Chequered Plates – IS 3502 2009 mandatory for several categories of steel products, including the plates check, through information under the orders of steel and steel products (quality control).

Major reason:

• IS 3502: Ensures compliance with 2009 (specification for steel checker plates)
• Guarantees equal quality, thickness and durability
• Prevents the circulation of substandard steel products
• Protects consumers, workers and industries from safety threats
• Enables smooth participation in government tenders and PSU contracts
