Complete Guide to Types of Welded Steel Grating for Industrial & Architectural Applications

Welded steel grating serves as a fundamental component in modern engineering and architecture, valued for its exceptional load-bearing capacity, durability, and corrosion resistance. It is widely used in industrial platforms, walkway systems, drainage covers, and building facades. As a specialized manufacturer, Shunbo offers a comprehensive range of welded steel grating products designed to meet functional and safety requirements across various applications.

1. What is Welded Steel Grating?

Welded steel grating is a metal grid panel formed by resistance-welding bearing bars and cross bars at their intersections. This structure creates a strong, rigid, and open panel. Common materials include carbon steel, stainless steel, and hot-dip galvanized steel, selected based on environmental and load conditions.

Key Advantages: Structural stability, high load-bearing capacity, ventilation and light transmission, easy installation, and low maintenance.


2. Common Types of Welded Steel Grating

2.1 Standard Welded Steel Grating

Features evenly spaced bearing bars and cross bars, providing uniform strength. Ideal for general industrial applications such as factory walkways and standard platforms.

2.2 Heavy-Duty Welded Steel Grating

Utilizes thicker bearing bars with closer spacing for significantly enhanced load capacity. Suitable for areas with heavy machinery, high-frequency traffic, and dockyards.

2.3 Stainless Steel Welded Grating

Offers excellent corrosion resistance, making it suitable for chemical plants, food processing facilities, marine environments, and high-humidity areas. Combines functionality with an aesthetic appeal.

2.4 Galvanized Welded Steel Grating

Treated with hot-dip galvanization to prevent rust and extend service life. Commonly used for outdoor stair treads, drainage covers, and external platforms.

3. Typical Application Scenarios

  • Industrial Settings: Factory platforms, equipment mezzanines, industrial walkways, and wastewater treatment plants, meeting both load-bearing and drainage/ventilation needs.

  • Architectural and Decorative Uses: Building facades, interior and exterior staircases, and landscape bridges, blending industrial aesthetics with functional design.

  • Harsh Environments: Chemical processing plants, coastal facilities, and salt-rich atmospheres. Stainless steel or galvanized types are recommended, often with serrated surfaces for anti-slip safety.

5. How to Select the Right Welded Steel Grating

  1. Define Load Requirements
    Estimate both concentrated and uniformly distributed loads based on actual usage to determine the appropriate bearing bar thickness and spacing.

  2. Consider Environmental Factors
    For humid, chemically aggressive, or coastal environments, stainless steel or hot-dip galvanized types are recommended.

  3. Customization Needs
    Custom sizes, shapes, and surface treatments (such as serrated anti-slip surfaces or special coatings) are available for specialized projects.

  4. Choose a Reliable Supplier
    Shunbo, as a professional grating manufacturer, provides end-to-end support—from technical selection and custom drawings to production and installation guidance.

6. Industry Trends & Innovations

  • Advanced Manufacturing: Automated welding and laser cutting technologies improve product precision and consistency.

  • Surface Treatment Tech: New nano-coatings and composite anti-corrosion treatments extend product life in extreme environments.

  • Integrated Design: Growing integration of steel grating with prefabricated buildings and modular structures.

7. Conclusion

Welded steel grating is an essential material in industrial and architectural fields, known for its structural reliability and adaptability. Selection should be based on a comprehensive evaluation of load, environment, material, and cost. Partnering with an experienced manufacturer ensures a solution that is safe, durable, and cost-effective.

HOT-SALE PRODUCT

Welded Steel Grating

Welded Steel Grating is a high-quality flooring and access material that consists of load -bearing bars and crossbars.

Standard Steel Grating

Standard steel grating, also known as Open Steel Grating , usually has a length ranging from 1000mm to 7500mm and a width ranging from 993 to 1000mm. Bearing Bars range from 20*3mm to 150*10mm. The surface is flat or serrated, and the surface treatment is galvanized, painted or untreated.

Press Locked Steel Grating

Press-Locked Bar Grating is a steel grating product that tightly locks the cross bars (typically shorter than the bearing bars) and bearing bars together using high-pressure mechanical equipment.

Press Welded Grating

​Shunbo pressure welded grating is used in various industrial fields, municipal engineering, construction and offshore drilling platforms, etc. Each intersection of the Bearing Bar and the Cross Bar is continuously welded to form an extremely stable and durable structure.
