Overview
The light duty steel grating from Hebei Shunbo is manufactured using Q235 low-carbon steel with grid spacing ranging from 30 mm to 100 mm. Compared to traditional cast iron gratings, this light duty steel grating achieves a weight reduction of 30–50%, enabling easier handling and installation, particularly for elevated or load-limited structures. Hot-dip galvanizing (≥85 μm recommended) or powder coating is applied for corrosion resistance.

Product Advantages
|
Attribute |
Data / Condition |
|
Weight reduction |
30–50% lighter than cast iron gratings (e.g., 15 kg vs. 25 kg for 1.2 m × 1.2 m panel) |
|
Installation efficiency |
40% less installation time compared to cast iron, based on standard two-person lift scenarios |
|
Load capacity |
Maintains ≥1000 kg/m² at grid spacings of 30–100 mm; deformation minimal under rated load |
|
Corrosion resistance |

Applications
Industrial facilities
Equipment walkways, platform treads in workshops (e.g., electronics or automotive plants); open grid design reduces dust accumulation and allows heat dissipation.
Municipal engineering
Drainage covers, tree pit gratings in parks and roads; lightweight design facilitates cleaning and maintenance.
Construction sector
Pedestrian walkways, viewing platforms in high-rise or outdoor areas; reduces structural load while maintaining stability.
FAQ
Q1: What material is recommended for light duty steel grating?
A: Q235 low-carbon steel is standard. Material test reports should be requested to verify quality.
Q2: How to select grid spacing based on use?
A: For pedestrian traffic only: 50 mm × 100 mm. For equipment support: 30 mm × 60 mm. The full allowable spacing range is 30–100 mm.
Q3: Which surface treatment is suitable for outdoor use?
A: Hot-dip galvanizing with minimum 85 μm coating thickness is recommended for humid or rainy environments. For chemical plants, stainless steel or weather-resistant steel is required.
Q4: Does Hebei Shunbo provide custom sizes or shapes?
A: Yes. Customized processing is available based on load requirements, span dimensions, shape, color, and budget.
