corrosion resistance and load-bearing capacity. Below are detailed specifications and characteristics of hot-dip galvanized grating with flat steel thicknesses of 3mm, 4mm, and 5mm:

Flat Steel Thickness

3mm:

Suitable for general load-bearing and corrosion-resistant applications.

Provides sufficient strength at a relatively low cost, making it ideal for various uses.

4mm:

Offers higher load-bearing capacity and enhanced corrosion resistance.

Commonly used in medium to heavy-duty applications.

5mm:

Ideal for heavy-load or highly corrosive environments.

Ensures structural stability and safety under extreme pressure and corrosion.

Size Specifications

In addition to flat steel thickness, hot-dip galvanized grating dimensions include:

Flat steel height

Bearing bar spacing (flat steel spacing)

Crossbar spacing

For example, G653/20/50 indicates:

65mm flat steel height

30mm bearing bar spacing

50mm crossbar spacing

Custom sizes are available based on project requirements.

Applications

Hot-dip galvanized grating is widely used in:

Industrial, construction, and municipal projects

Steel structure platforms, stair treads, trench covers, fences, and guardrails

Chemical plants, power stations, and water treatment facilities (where corrosion resistance and heavy-load capacity are essential).
