Frequently Asked Questions

What is the exact STC rating for the standard 50mm panel?

The 50mm thick steel panel with solid wood core achieves an STC of 48 dB per ASTM E90 testing. Adding double-glazed glass inserts reduces this to STC 42 dB, while full steel panels with acoustic insulation reach STC 50 dB.

Can the panels be painted to match specific RAL colors?

Yes, all steel panels are powder-coated in any RAL color at no extra charge for orders over 100 panels. Smaller orders may require a color matching fee of $50 per color. Wood veneers are available in oak, walnut, and maple.

Are these panels suitable for open-plan offices with frequent reconfiguration?

Yes, the demountable design allows panels to be disassembled and relocated without drywall damage. Each panel connects via interlocking steel channels with cam locks, enabling reconfiguration within hours by facility staff.

What is the minimum order quantity and pricing structure?

Minimum order is 20 panels for standard sizes. Pricing starts at $120 per panel for 50mm steel finish (FOB Shenzhen), with volume discounts for 100+ panels. Custom sizes or finishes may incur a 10-15% surcharge.

How are the panels packaged to prevent damage during sea freight?

Each panel is wrapped in 3mm thick foam sheeting, then placed in a plywood crate with foam corner supports. Crates are banded with steel straps and stacked on pallets. Damage rates are below 0.5% based on 2024 shipping data.
