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.
