Custom HDG Arc Sector Steel Grating Anti-corrosion Walkway Drainage Steel Grate

Fan Shaped Steel Grating is a customized metal grating solution designed for projects where standard rectangular grating panels cannot achieve precise installation. With its sector-shaped geometry and curved edge design, it is specially manufactured for circular structures, arc-shaped platforms, and irregular construction layouts.

Unlike conventional flat steel grating, fan-shaped grating is produced according to specific project dimensions to match curved areas such as circular equipment platforms, round tanks, spiral staircases, bridge structures, and architectural landscape facilities. This customized design improves installation accuracy, reduces cutting waste, and creates a cleaner finished appearance.

The grating is manufactured from Q235 carbon steel through a professional pressure welding process, forming a rigid structure with strong load-bearing capability. The welded connection between bearing bars and cross bars provides stable mechanical performance for pedestrian traffic, maintenance platforms, and industrial access areas.

After fabrication, the entire product undergoes hot-dip galvanizing treatment, creating a protective zinc coating that enhances resistance against corrosion, moisture, chemicals, and outdoor exposure. It is suitable for industrial plants, municipal infrastructure, wastewater facilities, power stations, and architectural projects requiring durable curved grating solutions.

Product Advantages

1. Customized Curved Design for Complex Layouts

The main advantage of fan-shaped steel grating is its ability to fit special-shaped installation areas that require precise geometric matching.

Applications include:

• Circular equipment platforms
• Arc-shaped walkways
• Round inspection platforms
• Curved drainage channels
• Spiral stair structures

The customized sector design allows better space utilization and provides a more integrated installation effect compared with modified standard grating panels.

2. Strong Load Capacity and Structural Stability

Manufactured using Q235 carbon steel and pressure welding technology, the grating provides reliable structural performance for various load conditions.

Structural advantages:

• High rigidity
• Strong impact resistance
• Stable welded joints
• Resistance to deformation under pressure

It can support regular pedestrian movement, maintenance operations, and industrial access requirements.

3. Hot-Dip Galvanized Protection for Harsh Environments

The complete hot-dip galvanizing process provides long-term corrosion protection by forming a durable zinc layer on the steel surface.

The galvanized surface helps resist:

• Rainwater corrosion
• Industrial moisture
• Chemical exposure
• Sewage environments
• Outdoor oxidation

This makes the grating suitable for chemical plants, water treatment facilities, power stations, and coastal projects.

4. Anti-Slip and Safe Walking Surface

The standard grid structure provides effective drainage and improves walking safety.

Functional benefits:

• Fast water drainage
• Reduced surface accumulation
• Improved ventilation
• Suitable for wet working environments

It is widely used in areas requiring safe access for workers and maintenance personnel.

5. Efficient Transportation and Project Installation

Fan-shaped steel gratings are manufactured according to project drawings and can be supplied in modular sections.

Advantages:

• Easy stacking
• Space-efficient packaging
• Suitable for container transportation
• Convenient on-site assembly

The standardized production process helps improve logistics efficiency for international projects.
