A: Yes, we offer internal locking mechanisms and hinge bolts as optional security upgrades. -
Q: Are custom sizes possible outside 600-800mm?
A: Custom diameters up to 1000mm can be engineered upon request. -
Q: How does ductile iron outperform cast iron?
A: Ductile iron has higher yield strength (40%+) and elongation (18-25%), reducing brittle fracture risks. -
Q: What is the lead time for 200-piece orders?
A: Typically 25-30 days ex-works, subject to specifications and production schedule. -
Q: Do covers comply with international standards?
A: Yes, designed to meet EN124 B125. Other standards (AS3996, etc.) achievable with adjustments. -
Q: Is hot-dip galvanization recommended for coastal areas?
A: Absolutely. It provides superior salt-spray corrosion resistance compared to paint alone. -
Q: Can you supply matching frames?
A: We offer composite or ductile iron frames designed for seamless integration.
