1. What material are your stair handrails made from?
We manufacture our handrails using premium carbon steel with a hot‑dip galvanized finish. This combination delivers solid structural strength and reliable corrosion resistance for long-term outdoor and industrial use.
2. How thick is the galvanized zinc coating?
The zinc coating weight reaches a minimum of 350g/m². This robust protective layer effectively resists rust and corrosion, keeping the handrail stable and durable in both indoor and outdoor conditions.
4. Can the handrails be customized for my project?
Fully custom solutions are available. We can adjust the railing height, pipe diameter, tube wall thickness, panel style and installation structure to match your exact project specifications.
4. Are these handrails suitable for outdoor installation?
Yes, they are perfectly suited for outdoor applications. The heavy hot‑dip galvanized coating provides excellent weather and salt-spray resistance, ideal for exterior stairs, balconies, terraces, industrial platforms and coastal sites.
5. How do you package the handrails for export shipping?
All products are wrapped with protective film and securely packed on standard export pallets or wooden cases. Corner protection is added to avoid scratches and deformation during transit. Custom packaging is also available for special project orders.
6. What is your standard lead time?
Production and delivery times vary based on order volume and shipping solution. Generally, full container (FCL) orders take 20–35 days, while LCL and air freight shipments can be arranged faster for smaller orders.
7. Are the handrails easy to install?
Absolutely. Our handrails are prefabricated with pre-drilled mounting points and optimized connection structures. We also tailor the assembly system to fit different site conditions for fast, straightforward installation.
8. Do galvanized handrails require regular maintenance?
Hot-dip galvanized railings are nearly maintenance-free. Simple routine cleaning is enough to preserve their surface condition and anti-corrosion performance for years.
9. Can you provide official documents for export clearance and inspection?
Yes. We supply complete supporting documents including product data sheets, factory test reports and qualification certificates to meet international export standards and project compliance requirements.
