Ductile Iron Square Walkway Grating For Outdoor Tree Slab Pit
Grating Applications
Product Features:
High Strength and Durability:
1.Ductile iron is twice as strong as ordinary gray cast iron,
30%-50% lighter, with a tensile strength of 400-1100 MPa, suitable
for heavy-duty scenarios (such as highways and airports).
2.Natural corrosion resistance: The surface oxide film can slow
down rust, and the service life can reach 15-20 years when combined
with galvanizing or coating treatment.
Functional Design:
1.Anti-theft and safety: The elastic self-locking structure
prevents the manhole cover from jumping and shifting, reducing the
risk of traffic accidents.
2.Drainage and anti-skid: The chessboard design or raised surface
enhances anti-skid properties and has high drainage efficiency
(opening rate ≥30%).
3.Environmental protection: No frequent maintenance is required,
reducing the need for slag removal, and is suitable for closed
scenarios such as fully buried pump stations
Typical application scenarios:
1. Municipal facilities: urban road drainage, power/communication
manhole covers, park tree pool enclosures.
2. Transportation infrastructure: highway drainage grilles, airport
cargo area heavy-load channels.
3. Environmental protection projects: sewage treatment pump station
crushing grilles, crushing solid particles to 6-10mm to prevent
equipment clogging.
Selection and maintenance recommendations
1. Selection basis: Select materials based on load-bearing grade
(such as D400 for roadways), environmental corrosiveness (select
galvanized or fiberglass composite materials) and low-temperature
toughness requirements.
2. Maintenance points: Regularly check the wear of the surface
coating, clean the blockages in the drainage holes, and avoid
deformation caused by mechanical impact.
Customization and aesthetics
1. Supports color, size, and pattern customization (such as city
logos), and optional surface treatment processes such as
sandblasting and chrome plating.
2. Hidden connection design avoids exposed solder joints and
improves overall aesthetics.
