Technical Whitepaper
Engineering Anatomy of Heavy-Duty Aluminum Mosquito & Security Screen Doors
In modern architectural fenestration, the conventional "fly screen" has evolved into an integrated envelope barrier. Specifiers no longer accept flimsy fiberglass mesh wrapped in lightweight rolled aluminum. Today’s international projects mandate unified structural security, coastal corrosion immunity, and unimpeded natural airflow.
01
Extrusion Metallurgy: 6063-T5 / T6
DERCHI implements virgin architectural billet alloys yielding a minimum wall profile thickness of 1.6mm to 2.5mm. With tensile strength exceeding 160 MPa and yield strength beyond 110 MPa, frames withstand intense torsional strain, dynamic cyclone gusts, and forced-entry pry leverage without corner joint distortion.
02
High-Tensile 304/316 Marine-Grade Mesh
Our OEM mosquito doors integrate micro-woven stainless steel wire screens (0.8mm to 1.0mm diameter) tested against knife-shear attacks (AS 5041) and high-impact impacts (AS 5039). The high-aperture precision weave prevents micro-insects like biting midges and mosquitoes while maintaining 82% ambient daylight transmittance.
03
Chemical Pre-treatment & AkzoNobel Finishes
To eliminate galvanic corrosion between the aluminum frame and the stainless steel mesh insert, we utilize non-conductive PVC/santoprene retention gaskets coupled with multi-stage zirconium pre-treatment. Architectural powder coatings rated up to 3,000 hours of continuous salt-spray testing protect against marine degradation.

Procurement Due Diligence
Frequently Asked Questions on Aluminum Mosquito Door Sourcing
Direct technical responses addressing common engineering queries from architects, quantity surveyors, and international distributors.
What are the key technical differences between 304 and 316 stainless steel screen mesh for coastal projects? +
Grade 304 stainless steel contains 18% chromium and 8% nickel, which provides excellent tensile barrier strength for general urban and inland environments. However, in marine and coastal climates exposed to airborne salt fog, Grade 316 is required. Grade 316 includes an addition of 2% to 3% molybdenum, significantly boosting resistance to chloride pitting corrosion and extending service life beyond 15 years without tea-staining or mechanical breakdown.
How does DERCHI prevent galvanic corrosion between aluminum door frames and stainless steel mesh? +
Galvanic corrosion occurs when dissimilar metals (such as aluminum and steel) make direct electrical contact in the presence of an electrolyte like moisture. DERCHI eliminates this reaction by implementing custom-extruded Santoprene or high-density EPDM dielectric insulating gaskets. The mesh edge is captured within this non-conductive barrier, and all structural assembly fasteners are insulated with high-grade zinc-nickel or Dacromet-coated components.
Can your OEM/ODM mosquito doors be integrated into existing thermal-break sliding and bifold doors? +
Yes. We design and manufacture triple-track sliding systems and external secondary snap-in track systems engineered to align seamlessly with thermal-break patio doors. Our engineering department supplies complete CAD shop drawings (.DWG/.DXF) and Revit BIM models to confirm track clearances, sill drainage run-offs, and handle clearances before tool fabrication.
What minimum technical data is needed to provide an accurate commercial quote? +
To generate a firm FOB/CIF commercial quotation within 24 hours, our engineering sales group requires: (1) Finished opening dimensions (width x height), (2) Desired profile wall thickness and thermal-break requirements, (3) Mesh specification (304 vs 316; mesh count and wire gauge), (4) Surface coating system (RAL color code and powder type), (5) Hardware configurations (single-point vs multi-point security lock), and (6) Total order volume and discharge port.
What export packaging measures safeguard powder-coated finishes during oceanic transit? +
Export door sets are wrapped in low-tack protective PE film, encapsulated with heavy-gauge EPE corner protectors, bundled in water-repellent corrugated sleeves, and packed within fully sealed, fumigated ISPM-15 compliant plywood crates. This eliminates profile surface friction, sea spray infiltration, and forklift transit damage during container handling.
