B2B Knowledge Base

Frequently Asked Procurement & Engineering Questions

Essential insights on engineering standards, lead times, maritime coatings, and custom OEM manufacturing workflows.

What surface coating is recommended for oceanfront or tropical salt-spray environments?

For installations located within 1,500 meters of the coastline (e.g., Caribbean, Florida, Southeast Asia, or coastal Australia), we recommend either a 3-Coat PVDF (Fluorocarbon) system compliant with AAMA 2605 or a Qualicoat Class 3 / Seaside Pre-treatment powder coating. These treatments pass 4,000+ hours of ASTM B117 salt spray exposure without peeling, bubbling, or filiform corrosion.

How does DERCHI verify hurricane impact and cyclonic wind resistance?

Our hurricane-impact casements, sliding patio doors, and heavy pivot systems are engineered and tested against AS 2047 (N6 cyclonic rating), ASTM E1886, and ASTM E1996. The structural test protocol includes missile impact testing (9-lb 2x4 lumber projectile fired at 50 ft/s) followed by 9,000 cyclic pressure reversals up to +4,500 Pa / -4,500 Pa.

Can you manufacture custom dimensions and match specific architectural schedules?

Yes. As a pure OEM/ODM factory, 100% of our production runs are built to custom architectural specifications. Our in-house engineering department converts architectural elevations and rough opening dimensions into detailed CAD and Revit BIM shop drawings, ensuring hardware cutouts, thermal breaks, and structural deadbolts align precisely with site requirements.

What is the standard manufacturing lead time for commercial container orders?

Following CAD shop drawing sign-off and color chip verification:
• Standard powder-coated finishes: 25 to 30 calendar days.
• Custom PVDF fluoropolymer, specialized woodgrain sublimation, or thermally broken fire-rated pivot assemblies: 32 to 38 calendar days.
Expedited production slots are available for phased tower deliveries.

What glass configurations are paired with your thermal-break aluminium systems?

We configure insulated glass units (IGU) according to project energy performance targets. Options include double- or triple-tempered Low-E glazing, laminated acoustic PVB/SentryGlas (SG) interlayers, argon gas fills, and warm-edge swisspacers, enabling total window-door assembly U-values down to 1.1 W/(m²·K) and SHGC tuning from 0.22 to 0.45.

How are the products packaged to ensure zero transit damage during ocean freight?

All assemblies receive a 5-tier export protective pack: 1) Adhesive electrostatic protective surface film; 2) EPE pearl cotton wrapping; 3) Corner edge protectors; 4) Sealed heavy-duty carton wrapping; 5) Fully enclosed ISPM-15 fumigation-free solid plywood crates loaded into steel-reinforced containers with desiccant packs to prevent condensation.
