Export-Grade Architectural Assemblies
Precision Fenestration Systems Engineered for North America
Direct factory production lines supplying multi-family residential developments, custom waterfront estates, and commercial hospitality retrofits across the Long Beach metropolitan corridor.
California Coastal Microclimates
Engineered Specifically for the Greater Long Beach Harbor Environment
Long Beach architecture spans vibrant downtown high-rises to luxury waterfront enclaves in Naples Island, Belmont Shore, and Alamitos Bay. Fenestration systems must satisfy strict thermal performance and withstand severe saline exposure.
Saline Air & High-Atmospheric Salt Fog
Marine-layer humidity along Ocean Boulevard accelerates galvanic corrosion. Our CR door systems utilize marine-grade fluorocarbon (PVDF) and architectural anodized finishes (AAMA 2605) tested up to 3,000 hours of continuous salt-spray exposure, ensuring hardware and finishes resist pitting.
California Title 24 Energy Compliance
California's Building Energy Efficiency Standards (Title 24 Part 6) mandate strict fenestration U-factors (typically ≤ 0.30) and Solar Heat Gain Coefficients (SHGC ≤ 0.23). Our multi-cavity PA66 nylon thermal isolators with dual Low-E tempered glass surpass Southern California Climate Zone 6 & 8 mandates.
Acoustic Attenuation (Port & Urban Transit)
With heavy cargo logistics around the Port of Long Beach and high-density corridor vibrations along I-710 and 2nd Street, interior comfort requires elevated Sound Transmission Class (STC) ratings. Dual-chamber laminated acoustic insulated glass units achieve STC 38–42 sound isolation.

Market Intelligence & Spatial Aesthetics
Emerging Fenestration Trends Across Greater Los Angeles & Orange County
Architectural demand across coastal California favors seamless transitions from indoor living areas to exterior courtyards and oceanfront terraces.
Concealed Pocket Glass Walls
Luxury coastal homes in Long Beach peninsula and Signal Hill favor multi-panel pocket sliders that disappear entirely into wall cavities, transforming living rooms into open-air verandas.
Ultra-Narrow Sightlines
Industrial-modern and Mid-Century Modern designs rely on structural aluminum profiles that minimize visible frame borders while supporting expansive tempered glass panes up to 10 feet tall.
Zero-Threshold Transitions
ADA-compatible flush-mount floor tracks featuring concealed subsurface drainage channels prevent tripping hazards while shielding interiors from heavy Pacific storm rain.
Smart Automated Facades
Direct integration with motorized actuators, home automation setups, and solar tracking systems provides high-end residential estates with automated ventilation and storm closures.

Local Sourcing Guidelines
Frequently Asked Questions by Long Beach Contractors & Developers
Direct technical answers addressing logistics, customs clearance, building code compliance, and direct factory procurement.
How do DERCHI aluminum door assemblies meet California Title 24 energy standards in Long Beach? +
Our systems use multi-cavity PA66 polyamide thermal breaks and high-performance dual- or triple-pane Low-E insulated glass units (such as Solarban 60/70 equivalents) filled with 90% argon gas. Each fenestration series comes with certified National Fenestration Rating Council (NFRC) test metrics meeting or exceeding Title 24 requirements for U-Factor (≤ 0.30) and SHGC (≤ 0.23) across California Climate Zones 6 and 8.
What shipping options and port logistics are available for delivery to Long Beach? +
Because Long Beach is home to the Port of Long Beach (one of the largest deep-water transpacific shipping hubs), orders ship directly from our Foshan factory to Long Beach terminals without inland rail transfer, helping reduce transit costs. We offer flexible terms including FOB, CIF, or full DDP (Delivered Duty Paid), which covers ocean freight, customs clearance, and flatbed delivery to your jobsite.
How do you safeguard door finishes against ocean salt spray and coastal corrosion? +
For coastal zones within 3 miles of the Pacific Ocean, we use architectural-grade 6063-T6 aluminum profiles coated with 3-coat PVDF fluoropolymer finishes compliant with AAMA 2605 specifications, or 25-micron hard-anodized coatings. All structural fasteners, handles, multi-point gearboxes, and roller tracks are crafted from marine-grade 304 or 316 stainless steel to prevent electrolytic and galvanic corrosion.
Can our order be customized to match imperial North American architectural plans? +
Yes. Every unit is manufactured to order. Our technical drafting department works directly from your architectural schedules using imperial dimensions (feet and inches), providing comprehensive CAD shop drawings, structural anchorage points, and flashing cross-sections for local engineer of record (EOR) review before production begins.
What crating and packaging measures prevent transit damage during transpacific shipping? +
All doors and windows are packaged in non-fumigation ISPM-15 compliant plywood crates. Each product component is wrapped in high-density polyethylene film, corner-protected with heavy foam guards, cushioned with shock-absorbent corrugated layers, and braced inside 40ft HQ shipping containers to maintain squareness throughout transpacific shipment.
What warranty and technical installation guidance do you offer to U.S. contractors? +
DERCHI provides a comprehensive 10-year warranty covering aluminum profiles, structural integrity, and finish adhesion, along with a 5-year warranty on multi-point hardware and insulated glass seals. Every project includes detailed digital installation guides, exploded component schematics, and video walk-throughs. Our engineers are also available for remote coordination with local sub-contractors.
