Frequently Asked Questions (FAQ):
Q: What is the delivery time?
A: The delivery time is usually 15-30 days.
Q: Can the pipes resist rust in humid or coastal areas?
A: Yes. The products can undergo passivation treatment, are highly weather-resistant, and can withstand harsh environments such as humid and coastal areas.
Q: Will the zinc coating easily fall off?
A: No. We use a mature hot-dip galvanizing process, and the zinc layer is tightly bonded to the steel pipe substrate, making it difficult to fall off under normal use.
Q: How do you maintain and clean glass curtain walls?
A: Our glass curtain walls are easy to maintain. Regular cleaning with mild detergent and water can keep them looking new. Avoid using abrasive cleaners to prevent scratches.
Q: Is quality inspection performed before shipment?
A: All products undergo multiple strict inspections, including dimensions, wall thickness, zinc coating, and appearance, before shipment to ensure quality.
