Heavy-Load plate stainless steel | Reinforced Grid Plates for Rail Systems

Heavy-Duty Stainless Steel Reinforced Grid Plates for Rail Systems

Product Overview

Engineered for extreme durability, our stainless steel strike plate and stainless steel tread plate solutions are designed to withstand heavy loads, corrosive environments, and high-traffic applications. These reinforced grid plates combine ASTM-certified stainless steel alloys with advanced manufacturing techniques, making them ideal for rail systems, industrial flooring, and infrastructure projects.

Technical Specifications

Key Properties & Performance

Tensile Strength

Our stainless steel plates exhibit exceptional tensile strength, ranging from 500 MPa to 1,000 MPa depending on the alloy and heat treatment . For example:

• ASTM 304: 515–750 MPa
• ASTM 316L: 485–690 MPa (enhanced corrosion resistance)
• ASTM 430: 450–600 MPa (high hardness for wear resistance)

This ensures resistance to deformation under heavy loads, making them suitable for rail track bases and machinery platforms.

Bending Strength

The elastic modulus of 190–210 GPa 

 allows these plates to maintain structural integrity even under repeated bending stress. Reinforced grid patterns further enhance rigidity, reducing deflection in applications like bridge decking.

Weight Calculation

Calculate plate weight using the formula:
$\text{Weight (kg)}=\text{Thickness (mm)}\times \text{Area (m²)}\times 7.9(\text{Density of steel, g/cm³})$
Example: A 1/8 stainless steel plate 4x8 (3.18mm thick, 1.22m x 2.44m) weighs approximately 74 kg.

Why Stainless Steel Resists Rust?

While stainless steel is highly corrosion-resistant, localized rusting can occur due to:

1. Chloride Exposure: Coastal or de-icing environments may cause pitting corrosion in grades like 430.
2. Mechanical Damage: Scratches or improper cleaning can compromise the passive chromium oxide layer.
3. Intergranular Corrosion: Low-quality alloys or improper welding may lead to chromium depletion at grain boundaries.

Our plates undergo pickling and passivation to restore the protective layer, ensuring longevity even in harsh conditions.

Identification & Marking

Plates are laser-etched with:

• ASTM Grade (e.g., 304, 316L)
• Thickness (e.g., 1/8")
• Batch Number for traceability
• Anti-Slip Pattern Code (e.g., Diamond 5D for stainless steel tread plate)

Price & Customization

Competitive pricing for 1/8 stainless steel plate 4x8 price starts at $850–$1,200 per sheet (varies by grade and finish). Custom sizes, perforations, and embossing available.

Why Choose Our Stainless Steel Plates?

1. Superior Corrosion Resistance: Chromium-nickel alloys ensure decades of service in moisture-rich environments.
2. Precision Manufacturing: CNC embossing and laser cutting for perfect fitment in rail systems.
3. Certified Quality: Compliance with ASTM, ISO 9001, and EN standards.
4. Cost Efficiency: Lower lifecycle costs due to minimal maintenance and replacement needs .
