I-beam gratings consist of I-shaped flat steel (thicker on the sides and thinner in the middle) and twisted steel (also known as twisted square steel, typically in 5x5, 6x6, and 8x8 sizes, twisted into reinforcing bars) arranged in an intersecting pattern, then welded together to form a metal product with square openings in the center. I-beam gratings are primarily used for drain covers, steel structure platform decks, and stair tread panels, offering features such as ventilation, lighting, heat dissipation, anti-slip, and explosion-proof.

II. Features of Type I Steel Grating:

1. Material Savings: Correspondingly, reducing the material used for the supporting structure under the same load-bearing conditions.

2. Reduce Investment: Save on materials, labor, and construction time, with easy cleaning and maintenance.

3. Easy Installation: Simply bolt or weld onto pre-installed supports; can be done by one person.

4. Save Construction Time: No on-site processing required for the products, with a rapid installation process.

5. Long-lasting use: Pre-treated with hot-dipped galvanizing for corrosion resistance and excellent shock and heavy load resistance.

6. Modern Elegance: Attractive appearance, standardized design, good ventilation and lighting, conveying an overall smooth and modern feel.

7. Lightweight Structure: Material usage is minimal, the structure is light, and it's easy for hoisting.

8. Anti-Dirt Accumulation: Resists water, ice, and dust buildup.

9. Reduce Wind Resistance: Due to good ventilation, less wind resistance in strong winds, reducing wind damage.

Section 3: Due to the aforementioned reasons, I-type steel grating is gaining increasingly widespread application in various fields.
