Compound steel grating is a combination of steel grating and a checkered plate or steel mesh, designed to offer high strength, durability, and slip resistance. It is commonly used in industrial, commercial, and architectural applications where robust flooring or platform solutions are required. This type of grating provides both structural support and a solid walking surface, making it ideal for use in hazardous environments.

1. Specifications of Compound Steel Grating

องค์ประกอบของวัสดุ

• Carbon Steel: Offers high tensile strength and durability for heavy-duty applications.

• Stainless Steel: Provides excellent corrosion resistance, especially in chemical or marine environments.

• Galvanized Steel: Hot-dip galvanized for enhanced resistance to rust and corrosion.

• Aluminum: Lightweight and corrosion-resistant, ideal for applications requiring reduced weight.

Surface Treatment Options

• Hot-Dip Galvanizing: Provides a thick, durable zinc coating to prevent rust.

• Powder Coating: Offers various color options for aesthetic appeal.

• Paint Coating: Enhances corrosion resistance and durability.

• Mill Finish: For applications where further coating is unnecessary.

Load-Bearing Capacity

• The load-bearing capacity depends on the size of the bearing bars, the spacing of the bars, and the thickness of the checkered plate.

• Heavy-duty options available for industrial use.

2. Models and Types

Based on the Checkered Plate Thickness

• 3 mm Plate: Suitable for light industrial use.

• 4 mm Plate: Medium-duty applications.

• 5 mm Plate and Above: Ideal for heavy-duty and high-load areas.

Based on Fabrication Methods

• Welded Compound Grating: Provides excellent strength and durability.

• Bolted Compound Grating: Allows for easy installation and maintenance.

Based on Bearing Bar Types

• Flat Bar Grating: Commonly used due to its superior load-bearing capacity.

• I-Bar Grating: Lightweight yet strong, often used for architectural purposes.

• Serrated Grating: Offers additional slip resistance, ideal for wet or oily environments.

Based on Surface Pattern

• Checkered Plate Surface: Provides slip resistance and covers open spaces.

• Steel Mesh Surface: Ensures better ventilation and drainage.

3. Dimensions

Bearing Bar Dimensions

• Thickness: Typically ranges from 3 mm to 10 mm.

• Width: From 20 mm to 150 mm, depending on load requirements.

Checkered Plate Dimensions

• Thickness: Generally between 3 mm and 6 mm.

• Width and Length: Standard dimensions are 1,000 mm x 6,000 mm, but custom sizes are available.

Spacing Configurations

• 30 mm x 100 mm: Standard spacing, ideal for general applications.

• 40 mm x 100 mm: Suitable for light-duty applications.

• 30 mm x 50 mm: Provides greater load-bearing capacity and slip resistance.

4. Design Considerations

• Load and Deflection: Ensure the grating meets the specified load requirements with minimal deflection.

• ความต้านทานการกัดกร่อน: Select appropriate materials and surface treatments based on the application environment.

• ต้านทานการลื่น: Choose serrated bearing bars or thicker checkered plates for areas prone to wet or oily conditions.

• Ventilation and Drainage: For applications requiring airflow and drainage, consider mesh-type compound grating.

5. Applications of Compound Steel Grating

• แพลตฟอร์มอุตสาหกรรม: Strong and durable for heavy machinery and equipment.

• Walkways and Bridges: Provides secure walking surfaces in industrial plants and outdoor spaces.

• Trench Covers and Drainage Systems: Combines strength and water drainage capabilities.

• Architectural Facades: Often used for aesthetic and functional purposes.

• Marine and Offshore Facilities: Corrosion-resistant materials ensure longevity in saltwater environments.

บทสรุป

Compound steel grating is an excellent solution for applications requiring both strength and a solid walking surface. With various material choices, surface treatments, and customizable dimensions, it can be tailored to meet the specific needs of any project. Its durability, slip resistance, and corrosion protection make it ideal for use in industrial, commercial, and architectural settings.
