การแนะนำ

Dense welded steel grating is a high-strength, durable grating option designed with closely spaced bearing bars. This type of grating is particularly suitable for applications requiring small openings, enhanced load capacity, and improved safety. Due to its structural integrity, dense welded steel grating is widely used in industrial plants, walkways, stair treads, and other facilities where strength and security are paramount.

This document provides a comprehensive overview of dense welded steel grating, including detailed specifications, available models, dimensional information, and other essential factors.

1. Specifications of Dense Welded Steel Grating

1.1. Material Composition

• Carbon Steel: Provides excellent strength and durability, ideal for heavy-duty industrial applications.

• Stainless Steel: Offers superior corrosion resistance, suitable for environments exposed to chemicals or moisture.

• Galvanized Steel: Coated with a zinc layer for enhanced corrosion protection in outdoor and industrial applications.

1.2. Surface Finish

• Hot-Dip Galvanizing: The most common finish for corrosion protection.

• Powder Coating: Offers additional protection and aesthetic customization.

• Mill Finish: Provides a clean steel appearance, primarily for indoor use.

1.3. Welded Construction

• Dense welded steel grating is produced by welding the bearing bars and cross bars together under pressure.

• This welding process results in a strong and rigid panel that can withstand heavy loads and impacts.

2. Models and Types

2.1. Based on Bearing Bar Profile

• Flat Bar Grating: Provides a standard load-bearing capacity and uniform appearance.

• Serrated Bar Grating: Features a serrated surface for enhanced slip resistance.

• I-Bar Grating: Reduces weight without compromising strength.

2.2. Based on Bar Spacing

• 19-W-4 Grating: Standard bar spacing with wider openings.

• Dense Spacing Grating (11-W-4 or 7-W-4): Closely spaced bearing bars, commonly used for ADA compliance and increased safety.

2.3. Specialty Types

• Heavy Duty Dense Grating: Designed for applications requiring extreme load-bearing capacities.

• Custom Fabricated Grating: Manufactured according to specific design and project requirements.

3. Dimensions

3.1. Bearing Bar Dimensions

• Thickness: Typically ranges from 3 mm to 12 mm.

• Height: Common heights include 20 mm, 25 mm, 30 mm, 40 mm, and 50 mm.

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

3.2. Cross Bar Dimensions

• Diameter: Usually 5 mm to 8 mm.

• Spacing: Standard cross bar spacing ranges from 50 mm to 100 mm.

3.3. Panel Sizes

• Standard Panel Size: 1,000 mm x 6,000 mm.

• Custom Panel Sizes: Available upon request to suit specific project needs.

4. Design Considerations

• กำลังรับน้ำหนัก: Ensure the bearing bar thickness and spacing align with load-bearing requirements.

• ต้านทานการลื่น: Select serrated bar grating for enhanced safety in wet or oily environments.

• Corrosion Protection: Choose galvanized or stainless steel for harsh or corrosive environments.

• Compliance: Dense grating with narrow spacing is suitable for ADA compliance in public areas.

5. Applications of Dense Welded Steel Grating

• Industrial Walkways and Platforms: Provides secure and durable flooring for workers.

• ดอกยางบันได: Ensures slip-resistant steps in industrial and commercial environments.

• ครอบคลุมร่องลึก: Allows efficient drainage while preventing debris from entering drainage systems.

• Parking Decks and Bridges: Supports vehicle loads while maintaining structural strength.

• Security Fencing and Screens: Offers robust barriers for industrial and commercial sites.
