As a professional casement window manufacturer with a 100,000 m² production base spanning Foshan and Zhaoqing, we are committed to supporting our clients at every stage — from initial consultation through years of reliable product performance.
Every successful project begins with a thorough understanding of your needs. Our pre-sales engineering team works closely with architects, developers, and distributors to design aluminum window and door systems that match your project specifications, budget, and performance requirements.
Once your order enters production, we keep you informed at every key milestone. Our quality control process ensures every product meets international standards before it leaves the factory.
We understand that safe and timely delivery is critical to your project schedule. Our logistics team coordinates every shipment to ensure your sliding door supplier order arrives in perfect condition, wherever your project is located.

A: Contact our support team via email or WhatsApp. We respond within 24 hours with a step-by-step troubleshooting guide including photos and videos. Most water intrusion issues stem from blocked drainage channels or weatherstrip compression, which can be resolved with our remote guidance. If replacement parts are needed, we dispatch them quickly from our spare parts inventory.
A: Slight misalignment can occur during installation or due to temperature-related frame movement. Our technical team provides detailed alignment adjustment guides with tool lists and instructional videos. Most clients resolve this in under 30 minutes. For our tilt and turn windows with Winkhaus hardware, we also offer direct video call support for precise adjustments.
A: Absolutely. We maintain digital records for every project, including dimensions, materials, and hardware specifications. Even for projects completed years ago, we can reproduce custom parts exactly. Custom replacement parts are typically produced within 10–15 days and shipped via express courier. We also keep tooling for our standard profile systems, ensuring long-term support without "obsolete product" issues.
A: We provide a comprehensive maintenance guide with every order. Key recommendations include: cleaning aluminum frames with mild soap and water every 3–6 months, lubricating hinges and hardware with silicone-based lubricant every 6–12 months, keeping drainage channels clear of debris, and inspecting weatherstripping annually. For coastal projects, we recommend more frequent rinsing to prevent salt buildup.
We guarantee a response to every inquiry within 24 hours through email, WhatsApp, or phone.
