Securing High-Temperature Industrial Zones and Fire Routes: Vich Heat-Resistant Alloy and Fire-Resistant Perforated Cable Trays

2026-07-17

​

 1. Fire-Resistant perforated cable trays: Balancing Daily Ventilation and Fire Insulation

Vich's Fire-Resistant Perforated cable trays employ an intelligent, dual-effect layout.

Routine Thermal Management: Precision-engineered ventilation patterns along the bottom profile facilitate continuous air convection, lowering cable heat build-up and improving transmission efficiency.

Intumescent Fire Barriers: The tray surface is coated with Vich's proprietary intumescent fire-retardant coat (typically 1mm~1.5mm thick). Upon direct fire exposure, the film reacts instantly, swelling dozens of times its original thickness into a dense carbonaceous foam matrix that blocks heat transfer.

Meeting the Highest Standards: Vich's fire-rated tray system meets the E60 standard (per DIN 4102-12 testing). In simulated fires up to 1000°, the system maintains cable circuit integrity for over 60 minutes, securing precious time for rescue operations.

【Fire-Rated Tray vs. Standard Tray Performance Comparison】

Technical Metric Vich E60 Fire-Rated Tray Vich Heat-Resistant Alloy Tray Standard HDG Steel Cable Tray
Working Temp Range -40°~120° -60°~350° -40°~150°
Thermal Conduction in Fire Extremely Low (Blocked by carbon layer) Low (Engineered alloy slows heat) Extremely High (Quick heat transfer)
Deformation Resistance Retains structure for 60min at 1000° Zero structural creep up to 800° Yield strength drops by half above 450°
Protective Finish Intumescent paint + Pre-galvanized Specialized high-temp finish Pure zinc layer
Fire Class Rating DIN 4102-12 E60 / UL 94 V-0 Certified for extreme heat radiation Non-combustible only; no thermal shield

Scalable Manufacturing Validating Premium Protection (Superior Production Capability)

Vich boasts Superior Production Capability, operating fully automated heavy-duty multi-point perforation lines alongside intelligent coating curing systems. This ensures rapid turnaround on high-volume orders, while verifying that coating applications are applied uniformly across every corner.

【Fire Safety Procurement FAQ】

: Steel is naturally non-combustible. Why must emergency routes use specialized "fire-rated" trays?

A: While steel doesn't burn, it conducts heat rapidly. Under fire exposure, heat transfers directly through the steel, melting cable jackets and causing immediate short circuits. Vich's fire-resistant trays block heat transfer, keeping internal temperatures below cable thresholds to protect critical signal transmission.

Q: Where are Vich's Heat-Resistant Alloy Trays typically deployed?

A: They are engineered for molten metal casting platforms, blast furnace perimeters, and glass melting chambers that face persistent 200°~350° thermal radiation. Under continuous extreme heat where standard metals soften and warp, our alloy trays maintain 100% structural rigidity.
