Customized Service Process

Project Planning & Creative Consultation
We begin by understanding your brand positioning and real-world application scenarios. Through in-depth discussions, we align on product objectives and performance expectations. You are encouraged to share any design concepts or functional requirements. Our engineering team then provides professional feasibility assessments and optimization suggestions, blending your vision with our fire safety expertise to co-create a solution that balances market appeal with regulatory compliance.
Drawing Submission & Technical Detailing
Please provide complete construction drawings with clear specifications, including dimensions, fire-resistance ratings, glass types, frame materials, installation requirements, and any special engineering notes. Our technical team will refine the designs, verify every parameter, and confirm all details with you to ensure full alignment before production.
Pre-Production Sampling & Final Approval
We produce a pre-production sample strictly according to the approved drawings. After internal quality checks, we ship the sample to you for thorough inspection and sign-off. This step locks in appearance, performance, and craftsmanship details, eliminating any ambiguity before we proceed to formal contracting.
Contract Signing & Order Confirmation
Once the sample is approved, we finalize all commercial terms—pricing, delivery schedule, quality standards, after-sales warranty, and liabilities—with clarity and transparency. A formal contract is then executed to secure mutual rights and obligations, laying a solid foundation for the cooperation.
Mass Production & On-Time Delivery
Upon contract effectiveness, our production line operates in full compliance with the contract terms and approved sample standards. Every finished unit undergoes multi-stage quality inspections before being professionally packaged and shipped via optimized logistics to ensure punctual delivery.
Delivery Support & Installation Assistance
After goods arrive at your designated site, we provide installation guidance as agreed—whether via remote video calls, detailed manuals, or on-site supervision. Our technical team ensures correct installation and optimal performance. Any installation-related queries are addressed within 24 hours.
Warranty Coverage & Scheduled Maintenance
We offer a clear warranty period (typically 2 to 5 years) starting from the delivery date, covering structural and functional defects under normal use. Maintenance recommendations are also provided to extend product life and ensure long-term reliability.
 Feedback Collection & Continuous Improvement
After each project is closed, we proactively request your satisfaction rating and improvement suggestions. All feedback is systematically integrated into our internal quality management system, driving ongoing upgrades in product design, manufacturing processes, and service quality.

Fire Resistance Test

Our in‑house fire test furnace supports regular random checks for internal quality control and process stability. For official project reports, we send samples to accredited third‑party laboratories, which conduct the complete combustion tests and issue independent certificates in full compliance with applicable standards. Self‑inspection enables early risk detection, while external testing provides legally valid documentation—together ensuring product quality and project acceptance with complete peace of mind.

Our Certificates

In order to ensure that all products and services achieve the necessary performance and durability required to satisfy all interested parties - customer and regulatory requirements, we have established a complete, scientific quality management system and apply it strictly in operation.
