Discover our heavy-duty profiles featuring seamlessly integrated insect screening, thermal insulation, and anti-burglary mesh configurations custom manufactured to precise project schedules.
In contemporary architectural design, the boundary between interior comfort and exterior exposure requires fenestration components that deliver uncompromised airflow, micro-pest exclusion, and structural security. Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI) leads the industry by establishing precise metallurgical benchmarks for B2B procurement partners worldwide. Standard residential flyscreens frequently deteriorate within 24 to 36 months due to galvanic corrosion, profile sag, and mechanical wear under intense ultraviolet irradiation. Our custom OEM mosquito net doors resolve these structural vulnerabilities through high-tensile 6063-T5 and 6063-T6 architectural grade aluminum extrusions coupled with high-specification woven mesh.
The structural integrity of an insect barrier door hinges upon frame extrusion wall thickness and corner crimping technology. While commercial suppliers often utilize thin gauge profiles (1.0mm to 1.2mm), our OEM production lines operate strictly with wall thicknesses ranging from 1.4mm to 2.5mm. Each mitered joint is secured with high-grade internal aluminum corner cleats and injected with two-part polyurethane structural adhesive (corner bonding agent), eliminating diagonal racking and air leakage.

Data-driven insights for commercial developers, fenestration distributors, and hospitality contractors navigating evolving global building codes.
The global construction market is decisively transitioning away from flimsy, detached screen sashes toward integrated "Security Screen Systems" (King Kong mesh). Importers and project specifiers require dual-function fenestration.
Universal accessibility codes (ADA compliance) and modern minimalist aesthetics mandate low-profile or completely concealed sub-sill drainage tracks without compromising insect barrier effectiveness.
Energy conservation mandates (Title 24, LEED v4, EU EPBD) now penalize thermal transfer across secondary screen framing. Specifiers demand low-carbon extrusions with high thermal barrier performance.
How our Foshan R&D laboratories are redefining screen technology through aerodynamic weave patterns, automated motorized drives, and electro-deposition coatings.
Traditional wire nets obstruct outward vision and impede airflow by up to 55%. Next-generation micron-level electro-drawing allows 18×18 and 20×20 mesh configurations with over 72% open area, enhancing natural cross-ventilation while blocking micro-insects such as midges and no-see-ums.
Modern luxury villas require screen systems that disappear seamlessly. Our engineering department provides OEM motorized rolling and side-drawing mosquito screens equipped with ultra-quiet 24V DC tubular brushless motors, compatible with Zigbee, Matter, and KNX automation protocols.
Direct contact between stainless steel mesh and aluminum framing induces galvanic electro-chemical corrosion in saline environments. DERCHI's proprietary engineering incorporates non-conductive PVC/EPDM co-extruded gaskets and non-metallic pressure clips, completely isolating dissimilar metals.
Direct answers addressing technical tolerances, minimum orders, surface integrity, and shipping logistics.
We strictly utilize virgin aluminum ingot extrusions in 6063-T5 or 6063-T6 temper. T5 provides excellent tensile yield strength (≥130 MPa) optimal for intricate multi-track extrusions, while T6 (≥180 MPa) is selected for high-wind-load commercial barrier doors subject to extreme positive and negative surface pressures.
Direct contact between aluminum and stainless steel accelerates galvanic degradation when moisture or salt electrolytes are present. DERCHI implements a dual-barrier isolation protocol: every mesh edge is clamped inside co-extruded EPDM/Santoprene insulating channel boots before mechanical wedging, ensuring zero metal-to-metal contact.
Yes. Approximately 60% of our production volume consists of custom OEM/ODM extrusions. We operate an in-house tooling division capable of producing custom extrusion dies within 12 to 15 working days. Sample extrusions and CMM inspection reports are submitted for approval prior to mass production.
Our door systems hold CE markings, ISO9001 quality system credentials, and Australian AS2047 testing certificates (rated up to cyclic N6 cyclonic pressures). For fire-rated barrier specifications, select door configurations hold UL ratings. We provide mill certificates, coating thickness verification, and third-party laboratory test reports.
Standard lead time for existing extrusion dies is 20 to 25 days following shop drawing sign-off and deposit receipt. For new custom die tooling, lead time is 30 to 35 days total. Expedited production lanes are available for multi-family residential or commercial hospitality phases requiring rolling delivery schedules.
Each unit undergoes five-layer export protective wrapping: protective peel-off film over all exposed powder coat, bubble-wrap inner encasement, heavy-gauge EPE corner protectors, corrugated outer wrap, and final fumigated non-coniferous plywood crating with internal steel strapping and moisture desiccant bags.
We supply three distinct mesh categories: (1) High-Tensile 0.8mm/0.9mm AISI 316 King Kong Marine Wire for security and pest protection; (2) Micro-Midge Stainless Steel 20×20 mesh for tiny biting insects in coastal mangroves; and (3) Heavy-duty PET/Fiberglass tear-resistant mesh for pet resilience.
For standard architectural RAL powder coat colors (Matte Black, Anthracite Grey, White, Bronze), our MOQ starts at just 10 square meters, facilitating bespoke luxury villa schedules. For specialized PVDF fluorocarbon coatings or custom extrusion shapes, minimum volume is 50 square meters or 500 kg of profile weight.
