I. EN124 Standard Requirements
1. Load Capacity Rating
- Heavy-duty rating corresponds to the specified rating and above. The core classification covers different load ranges, with one rating being the mainstream in the market.
- Products must be labeled with the rating, EN124 standard, and manufacturer information; otherwise, they are not compliant.
2. Material and Workmanship
- Specific grades of ductile iron are preferred; ordinary cast iron is prohibited. Precision casting is required (free from sand holes and cracks).
- Corrosion protection is mandatory (asphalt coating as the base; hot-dip galvanizing is recommended for highly corrosive environments).
3. Safety and Structure
- Anti-slip, anti-displacement, and anti-theft features (anti-theft bolts recommended).
- Opening ratio meets standard requirements, balancing drainage with anti-clogging and anti-injury measures.
4. Testing and Certification
Those wishing to circulate must pass third-party load-bearing, corrosion, dimensional, and high/low temperature impact tests to obtain EN124 compliance certification.
II. Characteristics
Superior Load-Bearing Capacity:
01
Long-Term Durability:
Ductile iron + compliant anti-corrosion coating, long service life, low maintenance costs;
02
Complies with EN124 standards, suitable for municipal, foreign-invested, and import/export scenarios;
03
04
High Cost-Effectiveness:
Cast iron is recyclable, resulting in lower long-term overall costs than ordinary gratings.
05
III. Specifications
Aperture ratio meets standard requirements, operating temperature adaptable to various extreme environments, supports standard packaging methods.
IV. Applicable Scenarios
Mainstream heavy-duty scenarios such as urban motor vehicle lanes, logistics parks, and industrial parks;
High-end:
Ultra-heavy load scenarios such as ports, mines, and heavy-duty factory areas;
Extra-heavy:
Ultra-high load special scenarios such as airport runways and giant ports.
V. Selection, Installation, and Maintenance Points
1
2
3
Regularly clean debris, regularly check the fixing and anti-corrosion measures, and shorten the inspection cycle in highly corrosive scenarios;
Replace with a compliant product of the same level and specifications after damage.
VI. Common Problems and Solutions
Replace with ductile iron grating of the corresponding grade; eliminate substandard products.
Remove rust and apply anti-corrosion coating; upgrade to hot-dip galvanizing for highly corrosive environments.
Tighten bolts, level the well frame, and install buffer pads.
Clean regularly, replace with appropriately perforated grating, and install filters.
Replace with anti-theft devices, and install warning signs or surveillance cameras.
VII. Product Advantages and Market Value
Strong compliance, high load-bearing capacity, long lifespan, wide applicability, safe and reliable.
Suitable for municipal upgrades, industrial development, and import/export trade; the first choice for high-end scenarios.
