Custom 60-Min Fire-Rated Rock Wool Panel System | CoatTech Intelligent Equipment
Engineered for space-constrained factories (5.60m & 6.20m width options). CoatTech provides CNAS-certified 60-minute fire-rated rock wool panel systems with 12–15 days of on-site installation and commissioning support.
come client also called it as custom industrial coating system, 60 minute fire rated panel, rock wool sandwich panel, compact spray booth layout, on-site commissioning service
Overview
When integrating new coating lines or partitioning industrial spray rooms, manufacturers often face two critical roadblocks:
narrow factory footprints and strict local fire safety regulations.
CoatTech's custom modular rock wool partition system is specifically engineered to solve both problems simultaneously. By combining millimeter-precise spatial layouts with certified 60-minute fire resistance, we ensure your equipment fits perfectly, passes local safety audits seamlessly, and operates reliably.
Key Highlights
1.60-Minute Fire Resistance Rating: Officially tested and certified under GB/T 9978 standards (CNAS / CMA / ILAC-MRA recognized).
2.Tailored Spatial Layouts: Pre-engineered options designed specifically for site widths capped at 5.60m (Option 1) or 6.20m (Option 2).
3.High-Density Insulation: Built with 50mm double-sided color steel panels filled with a 100 kg/m³ non-combustible rock wool core.
4.Turnkey On-Site Deployment: 1 experienced field engineer dispatched to your facility for 12–15 days of structural assembly, integration, and commissioning.
Dual Spatial Layout Options: Option 1 vs. Option 2
Standard equipment layouts often fail when space is strictly limited.
CoatTech provides two optimized structural configurations based on your exact plant boundary constraints:
Option 1: Recommended for Site Widths Capped at 5.60 m
1.Focus: Maximum space efficiency in tight operational corridors.
2.Design: Ultra-compact footprint that integrates panel walls and ductwork without compromising internal working space or safety clearance.

Frequently Asked Questions (FAQ)
Q: Is a 50mm rock wool sandwich panel sufficient for 1-hour fire resistance?
A: Yes. CoatTech’s 50mm wall panel utilizes high-density (100 kg/m³) rock wool bound with high-temperature adhesive and silicate fiber seam sealing. It has been officially certified under GB/T 9978 standards to maintain structural integrity and thermal insulation for a full 60 minutes.
Q: How do I choose between Option 1 (5.60m) and Option 2 (6.20m)?
A: If your available clear site width is strictly limited to 5.60 meters or less, select Option 1. If your facility allows up to 6.20 meters of width, select Option 2 to take advantage of wider maintenance and operator access lanes.
Q: What is included in the 12–15 day on-site installation service?
A: CoatTech provides 1 dedicated technician on-site to guide structural panel assembly, seal verification, duct/component alignment, initial system power-up, operational testing, and safety training for your maintenance personnel.
