Product Details

Steel tree grates are widely used in sidewalks, parks, and urban landscaping to protect tree roots while maintaining a clean and durable walking surface. Among various materials, weathering steel (Corten steel) has become one of the most popular choices for manufacturing tree grates because of its excellent corrosion resistance, strength, and natural architectural appearance.

Types of Corten Steel Tree Grates

Corten steel tree grates can be designed in different structures to meet various landscape and municipal engineering requirements.

1. Round Tree Grates
Round designs are commonly installed around individual trees in sidewalks or plazas. They usually consist of two or four segments that are assembled around the tree trunk, allowing easy installation and future tree growth.

2. Square Tree Grates
Square tree grates are widely used in urban streets and commercial areas. Their geometric structure provides strong load-bearing capacity and fits well with pavement layouts.

3. Rectangular Tree Grates
Rectangular designs are often used for long planting areas or continuous tree pits along streets and pedestrian zones.

4. Modular Tree Grates
Modular structures allow multiple grates to be combined into larger shapes, making them suitable for large public landscaping projects and flexible installations.

Manufacturing Process and Technical Principles

The production of Corten steel tree grates follows precise metal fabrication processes to ensure durability and structural stability.

Material Preparation
High-quality weathering steel plates such as Corten A or Corten B are selected as the raw material.

Precision Cutting
Laser cutting or CNC plasma cutting is used to create the grate openings and decorative patterns. This process ensures accurate dimensions and smooth edges.

Forming and Structural Reinforcement
The steel plates may undergo bending or edge reinforcement to increase structural strength and load-bearing capacity.

Welding and Assembly
Multiple steel components are welded together to form segmented or complete tree grate structures. Reinforcing frames are often added underneath to support heavy pedestrian or light vehicle loads.

Natural Oxidation Process
After installation, the surface of Corten steel gradually forms a dense rust layer when exposed to air and moisture. This oxidation layer acts as a protective barrier that slows further corrosion.

Advantages of Corten Steel Tree Grates

Excellent atmospheric corrosion resistance

Strong mechanical strength and load capacity

Low maintenance compared with traditional steel

Natural rust-colored surface that blends with landscape design

Long service life in outdoor environments
