Design decorative tree grill tree grates

Comparison between arlau's cast iron tree grates and ductile iron tree grates

1. Material and performance

Gray cast iron (cast iron grate):

Material: Graphite exists in flakes, the surface is gray, and the luster is darker.

Performance: Low strength and plasticity, high brittleness, but good vibration damping performance.

Applicable scenarios: Suitable for workpieces with low strength requirements and mainly subjected to compressive stress.

Ductile cast iron (ductile iron grate):

Material: Graphite exists in spherical form, the surface is gray, and the luster is brighter.

Performance: High strength, close to medium carbon steel, with good plasticity and toughness.

Applicable scenarios: Suitable for workpieces with high strength and toughness requirements and complex shapes, such as internal combustion engine crankshafts, connecting rods, etc.

2. Application scenarios

Cast iron grate:

Application: Commonly used in roads, sidewalks, docks and other places.

Features: It has high load-bearing capacity and good wear resistance, and the bottom adopts a reinforcing rib structure to improve the overall strength and stability.

Ductile iron grates:

Application: Suitable for occasions requiring higher strength and durability, such as motor vehicle lanes and alleys.

Features: High strength and good toughness, suitable for scenes with high strength and durability requirements.

3. Cost and maintenance

Cast iron grates:

Cost: Low material cost and simple manufacturing process.

Maintenance: Relatively low maintenance cost.

Ductile iron grates:

Cost: High material cost.

Maintenance: Durability and strength make it more advantageous in service life and maintenance cost.
