Engineering Overview & Technical Standards

Flexible PVC Strip Curtains and Protective Flap Barriers

DoorHan flexible PVC strip curtains provide a cost-effective, durable, and highly efficient solution for thermal zoning, dust suppression, acoustic isolation, and pest control across industrial doorways, walk-in cold rooms, refrigerated trucks, and warehouse loading docks. By allowing unobstructed pedestrian and forklift transit while immediately closing behind moving equipment, PVC curtains minimize heating and cooling losses.

Manufactured from premium-grade virgin PVC compounds with rounded, non-scratching edges, DoorHan curtains remain supple and transparent across extreme temperature ranges.

Key Technical Specifications & Engineering Standards:

  • Modular Stainless Steel Hook-On System: Fast-mount stainless steel suspension track allows individual strip installation, removal, and overlap adjustment (50%, 75%, 100%).
  • Polar Formulation: Specialized plasticizers ensure strips remain flexible without cracking or embrittlement in cold storage temperatures from -40°C to +15°C.
  • Ribbed Heavy-Duty Profile: Raised longitudinal ribs absorb forklift mechanical abrasion, preserving optical clarity of the flat curtain surface between ribs.
  • Acoustic and Environmental Attenuation: Reduces industrial background noise by up to 28–32 dB while blocking airborne dust, flying debris, and fumes.

Quality Assurance & Engineering Compliance:

DoorHan high-speed rapid roll-up and spiral doors are manufactured in accordance with strict CE directives, EN 12424 wind load criteria, and EN 12453 crushing protection standards. Designed for continuous 24/7 operations, our rapid door systems undergo accelerated life-cycle testing exceeding 1,000,000 cycles with minimal maintenance overhead. Turnkey integration is backed by full technical documentation, industrial controller schematics, and cleanroom air permeability certification data.

DoorHan PVC strip curtains offer an immediate return on investment by reducing refrigeration compressor loads and enhancing workplace comfort in high-traffic logistics environments.
