1. Overview of Stainless Steel Grating

Stainless steel grating is a highly durable, corrosion-resistant structural component widely used across industrial, commercial, and architectural sectors. Known for its strength, resistance to rust, and aesthetic appeal, stainless steel grating is commonly found in chemical plants, food processing facilities, marine environments, and modern architectural designs.

2. Technical Specifications

2.1 Types of Stainless Steel Grating

Stainless steel grating can be categorized based on its manufacturing process and intended load-bearing capacity:

1. Welded Stainless Steel Grating

This type is formed by welding the bearing bars and crossbars at high temperatures, creating a durable and high-strength grating. It is widely used for industrial flooring, drainage covers, and heavy-duty platforms.

2. Press-Locked Stainless Steel Grating

In this design, crossbars are pressed into bearing bars using high pressure, ensuring a smooth, uniform finish. This grating type is often chosen for architectural applications where aesthetics matter.

3. Swage-Locked Stainless Steel Grating

Manufactured through a swaging process that locks crossbars into bearing bars, swage-locked grating provides exceptional rigidity and strength. It is ideal for walkways, catwalks, and industrial settings.

4. Riveted Stainless Steel Grating

Riveted grating incorporates riveted connections between bearing and crossbars, offering outstanding load-bearing performance. This type is well-suited for areas requiring heavy vehicular movement.

2.2 Material Composition

• Common Stainless Steel Grades: 304, 316, 316L (high corrosion resistance for harsh environments)

• Bearing Bars: Thickness varies between 2mm and 10mm, made of high-strength stainless steel.

• Cross Bars: Available in twisted square rods or round bars for added structural integrity.

• Surface Finishes: Mill finish, electro-polished, or passivated for improved longevity.

2.3 Surface Treatment Options

• Electro-Polishing: Increases resistance to corrosion and enhances visual appeal.

• Passivation: Removes impurities and extends lifespan.

• Bead Blasting: Creates a matte finish, commonly used for architectural projects.

3. Standard Sizes and Configurations

3.1 Panel Dimensions

• Common Widths: 600mm, 800mm, 1000mm, or custom specifications.

• Length Options: 1000mm, 1200mm, 1500mm, 2000mm, up to 3000mm.

• Custom Dimensions: Available based on project needs.

3.2 Bearing Bar Spacing

• Standard Gaps: 19mm, 30mm, 40mm.

• Heavy-Load Configurations: Spacing of 50mm or more for vehicular traffic.

3.3 Cross Bar Spacing

• Typical Distances: 38mm, 50mm, or tailored to client requirements.

3.4 Load-Bearing Capabilities

• Ranges from 500 kg/m² to 5000 kg/m², depending on bar thickness and spacing.

4. Key Performance Features

4.1 Resistance to Corrosion

Stainless steel grating is highly resistant to oxidation, rust, and exposure to aggressive chemicals, making it the preferred choice for marine, food, and chemical processing environments.

4.2 Structural Strength & Durability

• Welded grating provides exceptional mechanical stability.

• Heavy-duty designs support vehicles such as forklifts and industrial transporters.

4.3 Anti-Slip Properties

• Serrated stainless steel grating enhances traction, reducing slip hazards in wet conditions.

4.4 Fire Resistance

• Non-combustible material, ensuring a high level of fire safety in industrial environments.

5. Common Applications of Stainless Steel Grating

• Food Processing Plants: Hygienic flooring in sterile environments.

• Marine & Offshore Platforms: Corrosion-resistant walkways and decks.

• Chemical Processing Facilities: Tolerates exposure to aggressive substances.
