Frequently Asked Questions

How does the galvanized steel sheet provide waterproof and windproof performance?

The hot-dip galvanized coating (Z275) creates a barrier against moisture and rust, while the sliding track system includes rubber seals at the bottom and side jambs to prevent water ingress and air leakage. Wind load resistance is tested to 1.5 kPa.

Can the color be customized for hotel branding?

Yes, we offer powder coating in any RAL color with a matte or gloss finish. Minimum order for custom color is 100 doors per batch, with a lead time of 15 days for color matching and application.

Is this door suitable for soundproofing in hotel rooms?

With a 32 dB STC rating, this door reduces noise from hallways and adjacent rooms by approximately 32 decibels, suitable for standard hotel guest rooms. For higher acoustic requirements, consider a solid core or double-glazed option.

What is the typical lead time for wholesale orders?

Standard lead time is 20–30 days after order confirmation and deposit. Custom colors or sizes may add 5–10 days. Sample doors can be shipped within 7 days.

How is the door packaged to prevent damage during international shipping?

Each door is wrapped in 5mm EPE foam and placed in a corrugated cardboard sleeve, then packed vertically in a wooden crate with internal bracing. Crates are stackable and sealed with waterproof plastic covering.
