Our Origin: Making Safety Part of Everyday Life

Derchi was born from a long-term commitment: remove potential risks before they surface. Instead of treating windows and doors as cold building materials, we study residential patterns and China’s living environments, then embed design, R&D, and patented technologies to build a protective “safety barrier” that users can feel every day. When prosperity is hard-won and happiness is precious, safety becomes non-negotiable.

Our Mission and Slogan

Mission

We place safety at the core of our brand, focusing on continuous innovation and refinement in windows and doors to provide consumers with safe and reliable products. Our goal is to set the benchmark for safety system windows and doors and to deliver an energy-saving, eco-friendly, safe, and comfortable system experience tailored to millions of families.

What the Slogan Stands For

For Love We Customize a Safe Home is both our core idea and brand slogan. It expresses a user-centric commitment to start from real living needs, customizing protection with warmth and care in everyday life.

The 360° Safety System

We operationalize “safety” through 3 Core Strengths and 6 Safety Technologies so performance stays consistent from design to daily use.

3 Core Strengths

Scale —

Industry-Flagship Production. A 70,000 m² modern plant in Foshan executes safety standards with advanced equipment, complete supporting processes, robust quality assurance, and a strong R&D team spanning “production–R&D–sales–marketing.”

Intelligent Manufacturing —

Industry 4.0. Heavy investment in smart automated lines raises efficiency and stabilizes quality, accelerating the shift from manufacturing to intelligent manufacturing.

Integration —

Global Partner Stack. We select top-tier suppliers and build strategic partnerships so critical materials start at a higher bar—Wehag, XYG, Hoppe, Haida, Technoform, among others.

6 Safety Technologies

Triple Sealing Structure—three continuous seals around the whole window to resist air/water ingress and reduce noise (utility patent).

Four-Sided Six-Point Lock—frame-sash engagement on four sides with six locking points for anti-pry security.

Anti-Water and Anti-Fall Design—engineered for sliding windows to cope with extreme weather and safety risks.

Vertical Isotherm Thermal Design—reduces thermal bridging for more stable indoor comfort.

Hardware Interior Installation—isolates hot/cold, reduces deformation, and extends smooth operation over time.

Premium Sealing System (Haida)—proactive leak defense with superior aging resistance versus conventional EPDM.

Trusted Worldwide Close to You with a Clear Vision

Why we are trusted

Our quality system is built for auditability and global acceptance—covering CE, ISO 9001:2015, AS2047 (Australia), NFRC (US), Canada certification, and ENERGY STAR (where applicable). Strategic alliances across hardware, aluminum, glazing, and sealing systems raise the baseline of every build and keep performance consistent from lot to lot.

Where you can find us

We operate internationally across North America, Europe, Oceania, Southeast Asia, South America, the Middle East, and Africa, complemented by a nationwide Chinese network of 700+ standardized brand stores with ongoing training. This “zero-distance” model shortens response times from consultation to installation and after-sales.

How we present our promise

Our brand symbols carry the meaning of safety in everyday life—the Shield for protection, the Heart for customization and care, and the Smile for a satisfied living experience. The voice is rigorous, warm, and quality-driven, reflecting a craftsman spirit applied to modern homes.

Where we are heading

Our vision is clear: to become the Chinese safety windows-and-doors brand recommended by users worldwide—expanding verifiable safety to more regions, projects, and families.

Research and Testing That Validate Safety

We build safety into the development cycle—prototype, validate, then scale—so designs behave as specified when they reach your site.

Validation Testing

In our Safety Testing Center, complete window units are verified in an integrated chamber for wind pressure, air tightness, and water tightness. Spray racks, water mist, pressure gauges, and live data capture are visible during the run, while an engineer in PPE monitors conditions to keep the test protocol stable and repeatable.

Scaling to Production

After validation, proven parameters are transferred to Industry 4.0 automation—CNC cutting, precision machining, or timed assembly stations. Barcodes, station QC cards, and Andon boards (can be softly blurred) signal standardized inspection gates and full traceability. The goal is to preserve validated tolerances and performance at mass-production scale.

On-Site Proof

We validate performance where it matters—on the installed project. A technician scans the interior side with a thermal camera, with the window and device screen in the same frame, showing real-time heat distribution for insulation verification. If needed, a sound meter can confirm acoustic results in noisy environments with clear readings.

Logistics & Shipping Support

We offer flexible logistics solutions across sea, land, and air to match your schedule and budget. Multiple Incoterms are available—including EXW, FOB, CIF, and DDP—so you can choose anything from factory pickup to fully managed door-to-door delivery. Our team coordinates routing, documentation, and handover milestones to keep shipments predictable and execution risk under control.

After-Sales Warranty Coverage

Our after-sales support covers four core components—glass, hardware, seals, and insulation strips. From the purchase date, each category includes up to 10 years of free repair or replacement when issues occur under normal use and are confirmed as material or manufacturing defects.

Glass

Within 10 years of purchase, free repair or replacement for self-explosion, fogging inside insulated glass, decorative bar defects, or tempered dimming defects. Coverage applies after inspection and verification.

Hardware

Within 10 years, free repair or replacement for functional failures in handles, hinges, and locks. Coverage focuses on parts that cannot operate as intended under normal use.

Seals
