Frequently Asked Questions (FAQ) for Global B2B Net Door Buyers
Key considerations for architectural specifiers, door importers, contractors, and project developers sourcing custom aluminum screen doors from China.
Where is the KARON factory located and what is your manufacturing capacity?
Karon Window & Door Co., Ltd. operates a 10,000 m² standardized manufacturing facility in Songxia Industrial Park, Nanhai District, Foshan City, Guangdong, China. Located at the heart of China’s premium aluminum manufacturing hub, our factory produces over 150,000 m² of custom architectural aluminum windows, screen doors, sunrooms, and glass railings annually. We maintain 8 automated extrusion lines, precision CNC machining centers, corner crimping equipment, and dedicated mesh tensioning stations.
What international testing standards and certifications do your aluminum net doors comply with?
Our product ranges are engineered to meet stringent regional building codes. For structural safety glazing, we hold EU CE (EN 12150), US SGCC, Australia AS 2208, and New Zealand AS/NZS 2208 certifications for single and laminated glass. For structural aluminum strength and insect screen performance, our products comply with Australia AS 4420 / AS 2047, Thailand TISI 965-2560 & 1231-2560, and Malaysia CIDB PPS standards. Production is strictly audited under ISO 9001 quality control management.
What is the difference between woven stainless steel security mesh and polyester pleated net doors?
Woven stainless steel mesh (often called King Kong Mesh) utilizes rigid 0.7mm to 0.9mm 304/316 wire. It functions primarily as an anti-theft security screen, offering high impact resistance, knife-shearing protection, and optical clarity while keeping insects out. Pleated polyester net doors feature soft, accordion-style folding screens that collapse neatly into side frames. Pleated systems excel in wide span openings where trackless floor thresholds and ultra-compact frame profiles are required, though they provide insect defense rather than structural anti-burglary protection.
Can you fabricate custom aluminum net doors to specific architectural drawings and window schedules?
Yes, 100% of our production is custom-engineered to client window schedules and CAD drawings. We customize frame alloy choices (6063-T5 / 6061-T6), frame colors (AkzoNobel powder coating, anodizing, fluorocarbon PVDF, wood grain transfer), screen mesh gauges, hardware locksets (HOPO, CMECH, SIEGENIA, ROTO), and mounting accessories. Our engineering team reviews shop drawings to confirm dimensions, wind-load capacity, and thermal break specs before production kick-off.
How do you ensure surface powder coating durability for coastal or humid environments?
For harsh coastal or high-humidity tropical climates (such as Florida, Australia, or Southeast Asia), we specify Qualicoat Class 2 architectural powder coatings or PVDF (Fluorocarbon) finishes. Aluminum profiles undergo a 9-stage pre-treatment cleaning and chromating process to maximize coating adhesion. Our finished profiles withstand over 2,000 hours of neutral salt spray testing (ASTM B117) without chalking, cracking, or blistering.
What is your typical lead time, minimum order quantity (MOQ), and shipping protection protocol?
Our standard production lead time is 20 to 30 working days following CAD drawing sign-off and deposit confirmation. We accommodate flexible MOQs for project buyers—ranging from custom single-villa packages up to multi-container commercial hotel shipments. All products are wrapped with protective film, corner guards, water-resistant shrink wrap, and packed into ISPM-15 certified fumigated wooden crates to guarantee zero transit damage during sea freight container shipping.
