Products Description
This series of plastic coated flexible metal hoses adopt precisely occluded metal corrugated substrate with smooth bending, strong tensile and extrusion resistance, and no easy deformation or fracture. The outer layer is integrally coated with new weather-resistant plastic raw materials, closely attached to the metal substrate without hollowing or delamination. The surface is smooth and burr-free with high water and dust resistance. The outer plastic layer is modified with UV and aging resistance, which can adapt to long-term outdoor exposure, humidity, rain and salt spray environments without peeling, cracking or fading. The inner metal structure ensures the overall toughness and compression resistance of the pipeline, supporting free bending and layout in narrow spaces, special-shaped wiring and equipment dynamic displacement scenarios. With multiple performances of insulation, flame retardancy, corrosion resistance, wear resistance, water and moisture resistance, it is produced with standardized processes with regular dimensions and wide compatibility with various fittings, widely used in electrical cable protection, mechanical equipment wiring, outdoor engineering wiring and humid area pipeline protection.

Product Advantages
Double-layer composite structure with upgraded comprehensive protection
The inner metal layer resists compression, tension and collapse, while the outer plastic layer provides insulation, waterproofing, corrosion and wear resistance. The dual complementary protection completely solves the problems of rusting, electric leakage, wear and water ingress of bare metal hoses, greatly extending the service life.
Insulation and flame retardancy for safe electrical wiring
The outer plastic layer has excellent insulation performance, effectively isolating electric leakage and static electricity to avoid short circuit risks caused by exposed cables. Optional high flame-retardant modified material self-extinguishes fire without spreading, suitable for high-safety wiring scenarios such as computer rooms and electric control cabinets.
Weather and aging resistance for harsh outdoor environments
UV-resistant and weather-modified outer layer resists strong sunlight exposure, rain erosion, moisture condensation and coastal salt spray corrosion, maintaining stable performance without cracking, peeling or fading during long-term outdoor operation.
High flexibility and easy construction with strong wiring adaptability
The occluded corrugated structure bends flexibly, supporting multi-angle bending, wall penetration and special-shaped wiring without dead folding or blockage. It adapts to dynamic equipment displacement and complex wiring in narrow spaces with high construction tolerance.
Wear and scratch resistance to protect internal cables
The smooth and tough outer plastic surface resists scratches and wear during layout, effectively protecting internal wires and cables from insulation damage and avoiding equipment faults and safety hazards.Custom

Product Q&A
Q: What is the core difference between plastic-coated flexible metal hoses and ordinary bare metal hoses?
A: Ordinary bare metal hoses only have basic flexibility without outer protection, prone to rust, corrosion and electric leakage in outdoor and humid environments. Plastic coated hoses are equipped with weather-resistant and insulating plastic outer layers, featuring waterproofing, insulation, flame retardancy and aging resistance. They are specially designed for electrical wiring and humid outdoor conditions with much higher safety protection levels.
Q: Will the outer plastic layer peel or crack after long-term use?
A: Qualified weather-resistant modified PVC/PE materials will not peel or crack under normal working conditions. Treated with UV and aging resistance processes, it adapts to long-term sunlight and humid environments. Aging will be accelerated only when exposed to strong corrosive solvents or over-temperature environments, ensuring stable performance in conventional electrical and outdoor scenarios.
Q: Can plastic-coated flexible metal hoses resist acid and alkali corrosion?
A: Yes. The professional protective coating has excellent resistance to weak acid, weak alkali, oil stain and water corrosion. It protects the inner metal substrate from medium erosion in general chemical, oil-water mixed and humid corrosive environments, greatly extending the service life under harsh working conditions.
