Comprehensive Facility Overview
Jiahui operates state-of-the-art production facilities specializing in high-performance door systems, integrating advanced automation, rigorous quality control, and sustainable practices. Our factories span multiple strategic locations in China, enabling large-scale, customized manufacturing for global clients. Below is a detailed breakdown of our capabilities:
? 1. Production Scale & Infrastructure
Total Facility Footprint: 80,000 m² land area with 100,000 m² built-up space across 3 key industrial hubs in Zhejiang, Shanghai, and Jiangsu.
Daily Output: 1,000+ door units/day, including steel fire doors, wood fire doors, cast aluminum doors, and medical/access doors.
Annual Capacity: Exceeds 600,000 units, supporting bulk orders and rapid delivery timelines.
⚙️ 2. Core Product Lines & Advanced Manufacturing
Fire-Rated Doors
Steel Fire Doors:
Built with 1.0–1.5mm galvanized steel (door leaf/frame) and filled with perlite + steel reinforcement for thermal insulation.
Compliant with UL/BS476/EN certifications; withstands 90–180 mins of fire exposure.
Wood Fire Doors:
Engineered for commercial use, featuring intumescent seals and Class A flame-spread resistance.
Specialized Door Systems
Cast Aluminum Doors: High-precision sand-casting molds with powder-coated finishes (200+ color options).
Medical Doors: Antibacterial coatings, impact-resistant cores, and silent-closing mechanisms for hospital environments.
Unit Entry Doors: Ballistic-grade steel construction, integrated panic hardware (e.g., touchless exit devices).
? 3. Automation & Technology Integration
Smart Fabrication:
Laser cutting & CNC turret punching for ±0.1mm dimensional accuracy.
Robotic welding (100+ ABB robots) ensuring structural consistency.
Surface Treatment:
E-coating & Powder Coating: British Eluda electrostatic lines with VOC-reduction systems (30% lower emissions).
Heat-transfer printing for wood-grain/textured finishes.
? 4. Quality Assurance & Compliance
12-Stage Testing Protocol: Includes fire endurance (per GB/T 7633), impact resistance (30kg sandbag @1.5m), and air-tightness validation (≤1.5 m³/(m·h) @50Pa).
Certifications: ISO 9001, ISO 14001, CE, Intertek WHI, and Chinese fire safety GB standards.
Traceability: Full digital records for materials, production parameters, and test results per unit.
? 5. Global Logistics & Sustainability
Export Readiness: 25-day lead time from Ningbo/Shanghai ports; packaging uses recyclable foam/carton materials.
Zero-Waste Initiatives: Closed-loop water systems and RTO (Regenerative Thermal Oxidizer) tech for VOC abatement.
