Manufacture Grating System

Manufactured Grating Metal System – Detailed Description

A manufactured grating metal system is an engineered structural product composed of interconnected metal bars arranged in a grid or mesh pattern. These systems are designed for use in various industrial, commercial, and architectural applications, offering durability, high load-bearing capacity, and enhanced safety. They are commonly used for flooring, walkways, drainage covers, and security enclosures.

1. Materials & Coatings

Manufactured metal grating is available in different materials and finishes to suit various environmental conditions and structural requirements:

Common Materials:

• Mild Steel (Carbon Steel): High strength and cost-effective, often hot-dip galvanized for corrosion resistance.
• Stainless Steel (304, 316): Corrosion-resistant, ideal for food processing, chemical, and marine environments.
• Aluminum: Lightweight and corrosion-resistant, suitable for architectural and non-load-bearing applications.

Surface Finishes & Coatings:

• Galvanized (Hot-Dip or Electroplated): Protects against rust and corrosion.
• Painted or Powder-Coated: Provides aesthetic appeal and additional protection.
• Mill Finish: Standard untreated finish for general-purpose use.

2. Types of Metal Grating

Different grating types are designed to meet specific load, safety, and functional needs:

1. Welded Steel Grating

• Constructed by welding load-bearing bars and cross bars together at intersections.
• High strength and durability, suitable for heavy-load applications.
• Available with plain or serrated surfaces for slip resistance.

2. Press-Locked Grating

• Manufactured by pressing cross bars into notched load bars under high pressure.
• Provides a clean, uniform look, ideal for architectural and commercial applications.
• Offers strength with aesthetic appeal.

3. Swage-Locked Grating

• Made by swaging cross bars into pre-punched load-bearing bars.
• Commonly used in aluminum grating for lightweight and non-corrosive applications.
• Provides excellent durability with minimal welding.

4. Expanded Metal Grating

• Manufactured by stretching and slitting a sheet of metal to form a diamond-shaped pattern.
• Lightweight with good ventilation properties.
• Used for security panels, fencing, and lightweight flooring.

3. Load-Bearing & Strength

Manufactured metal grating is designed to support heavy loads while maintaining structural integrity. It is categorized based on:

• Load Bar Thickness & Spacing: Determines the strength and load capacity.
• Deflection Standards: Compliance with ANSI/NAAMM (National Association of Architectural Metal Manufacturers) load tables.
• Impact Resistance: Designed for pedestrian and vehicular traffic.

4. Surface & Safety Features

To enhance functionality and safety, metal grating can have various surface treatments:

• Serrated Surface: Provides increased grip and slip resistance, ideal for wet or oily environments.
• Smooth Surface: Easier to clean and suitable for indoor use.
• Open Mesh Design: Allows drainage and airflow while preventing debris buildup.

5. Common Applications

Industrial & Commercial Uses:

• Factory walkways, mezzanine floors, and platforms.
• Stair treads and catwalks for industrial plants and warehouses.
• Heavy-duty trench covers and drain grates.

Architectural & Decorative Uses:

• Facades, sunshades, and fencing.
• Decorative security panels and urban infrastructure.

Marine & Offshore Applications:

• Ship decks, docks, and offshore platforms due to corrosion resistance.

6. Customization & Fabrication

Metal grating systems can be customized based on:

• Size & Panel Dimensions (width, length, thickness).
• Load & Strength Requirements (light, medium, heavy duty).
• Attachment & Installation Options (fasteners, welding, clips).

Conclusion

A manufactured grating metal system is a versatile and durable solution for flooring, safety, and architectural applications. With various material choices, designs, and finishes, these systems provide strength, longevity, and aesthetic appeal. Their ability to withstand extreme conditions makes them a preferred choice for industrial, commercial, and marine environments.
