A36 Hot Rolled Diamond Plate - 3/8" x 48" x 120"

This 3/8" x 48" x 120" hot rolled diamond plate is a heavy-duty structural steel sheet with a raised, slip-resistant pattern. Conforming to ASTM A786 and A36 standards, it provides excellent durability and weldability for demanding industrial applications requiring safe, load-bearing surfaces. In stock Los Angeles.

  • A36 Hot Rolled Steel Construction
  • ASTM A786 / A36 Certified
  • 58,000-80,000 PSI Tensile Strength
  • Maximum Skid Resistance
Overview | Specifications | Applications | Finish Options | How to Measure | Order Checklist

Hot rolled diamond plate, also known as tread plate, is produced from A36 structural steel, combining formability and strength with functional slip resistance. The hot rolling process gives it a durable but less refined mill scale surface, perfectly suited for demanding industrial, automotive, and construction environments where durability and safety are the primary requirements. The A36 base ensures excellent weldability.

The substantial 3/8 inch thickness of this plate makes it ideal for large-scale, heavy-duty applications. It is commonly used for industrial flooring in high-traffic areas, heavy equipment mounting bases, loading dock ramps, and wear plates where impact and abrasion resistance are critical.

Specifications

  • Material: A36 Hot Rolled Steel
  • Standards: ASTM A786 (Pattern), ASTM A36 (Material)
  • Strength/Tensile: 58,000-80,000 PSI
  • Dimensions: 3/8" Thickness x 48" Width x 120" Length
  • Finish: Hot Rolled (Mill Scale)
  • Certifications: MTR Available

Applications

  • Industrial & Factory: Heavy-duty work platforms and catwalks - for providing a safe, high-strength walking surface.
  • Construction: Loading dock ramps and trench covers - chosen for its high strength and load-bearing capacity.
  • Transportation & Automotive: Heavy trailer floors and truck bed liners - for superior impact and abrasion resistance.
  • Utility & Off-Road: Vehicle armor and skid plates - for maximum durability and protection in harsh environments.

Target Users

Fabricators, welders, construction contractors, and heavy equipment manufacturers rely on A36 diamond plate for its strength and safety in industrial projects throughout the Los Angeles area.

Finish Options

This product comes standard with a raw hot-rolled surface that has a blue-grey mill scale. For best results with painting or powder coating, this scale should be removed by grinding, sandblasting, or chemical pickling. Left untreated, it will develop a surface rust patina. Contact our Los Angeles sales team for custom finish inquiries.

How to Measure

Diamond plate is measured by its nominal thickness, width, and length. The thickness is measured from the base of the plate, not including the height of the raised pattern.

Example: To order this plate, specify "Hot Rolled Diamond Plate, 3/8" x 48" x 120"".

Order Checklist

  • Product name and required dimensions (3/8" x 48" x 120")
  • Material specification and quantity
  • Confirm grade (A36) meets requirements
  • Surface finish requirements (Hot Rolled Mill Finish)
  • Certifications required (Mill Test Report)
  • Special cutting or delivery requirements
