Hot-Dipped Galvanized Steel Grating Product  Introduction

Technical Parameters 

Material

Q235 low-carbon steel (good mechanical properties, affordable) or stainless steel (304, 316, excellent corrosion resistance for special environments).

Specification (Load-bearing Flat Bar × Cross Bar):

Load-bearing flat bars: 20×5, 25×5, 30×3, 30×5, 40×5, 50×5 mm, etc.

Cross bars: 5×5, 6×6, 8×8 mm, etc.

Different combinations meet various load-bearing demands.

Mesh Size:

Commonly used: 30×100, 40×100, 60×100 mm, etc.

Smaller meshes suit high-safety areas to prevent small object falls.

Larger meshes focus on ventilation, drainage, and cost-efficiency.

Galvanized Layer Thickness:

After hot-dipping, the average thickness is ≥85μm, and local thickness is ≥70μm.

Meets national standards for effective corrosion resistance and extended service life.

Bearing Capacity:

Varies by specification. For example, 303/30/100 steel grating has a uniform load of 3.5kN/m² and a concentrated load of 3.85kN.

Choose the right specification based on actual load requirements.

Surface Treatment:

Hot-dip galvanization forms a uniform, dense zinc layer for enhanced corrosion resistance.

Cold galvanization and painting are also available upon request.

FAQ：

Q: How long can the hot - dipped galvanized steel grating last?

A: In normal outdoor conditions, it can last over 20 years due to the thick anti - corrosion zinc layer. But lifespan may vary in special environments like chemical plants.

Q: Can the steel grating be customized?

A: Absolutely. We can customize the size, shape, and load - bearing capacity according to your needs. Just let us know your specific requirements.

Q: What's the installation process like?

A: It's quite simple. First, align the grating accurately. Then, secure it using bolts or welding. Installation time is short, saving you both time and labor costs.

Q: How to maintain the hot - dipped galvanized steel grating?

A: Maintenance is easy. Just conduct occasional inspections. Since it has high corrosion resistance, there's no need for frequent upkeep. Only repair if any damage is found.

Application

Industrial plant

Used for laying workshop floors, equipment operation platforms, maintenance walkways, and escalator treads. It has strong load-bearing capacity, anti-corrosion durability, and is suitable for damp, oily, and easily worn environments in workshops. It also meets the needs of ventilation, heat dissipation, and daily maintenance.

Logistics warehouse

Suitable for loading and unloading platforms, storage area platforms, ventilated floors, and cargo stacking brackets, capable of withstanding heavy pressure from goods and loading and unloading equipment. The hot-dip galvanized layer resists moisture and corrosion, and the anti slip design ensures operational safety.

Municipal facilities

They are used in the grids of sewage treatment plants, protective grids of sedimentation tanks, urban road drainage well covers, rainwater grids, and ventilation grids of bridges, sidewalks, and underground passages. They are anti-aging, load-bearing, and suitable for outdoor complex environments.

Electric power and chemical industry

Used for power plant equipment platforms, maintenance walkways, cable trench covers, chemical plant workshop floors, reaction kettle operation platforms, to resist chemical medium corrosion and equipment operating environment impacts, ensuring operational safety.
