Fireproof cable tray manufacturer national standard thickness

Fireproof cable trays are available from manufacturers like SFSP, EAE Electric, and others, with standard thicknesses ranging from 1.0 mm to 6 mm depending on material and duty type.

Key Manufacturers and Products

• SFSP: Produces steel cable trays and accessories compliant with BS EN 61537:2023, NEMA standards, and cabling standards like CENELEC EN 50173-1. Materials include pre-galvanized, hot-dip galvanized, stainless steel, and aluminum. Standard thicknesses are 1.0 mm, 1.2 mm, 1.5 mm, and 2.0 mm .
• EAE Electric: Offers medium and heavy-duty cable trays using the Roll Forming method. Materials include pre-galvanized, hot-dip galvanized, painted, and stainless steel. Thicknesses range from 2 mm to 6 mm, depending on coating type and load requirements .
• Zeroinstrument: Provides technical guidelines for fireproof cable tray installation, recommending painted steel or galvanized trays for indoor use, and hot-dip galvanized or stainless steel for outdoor or high-humidity environments. Thickness selection is based on cable weight and mechanical strength requirements .

Material and Fireproof Considerations

• Steel and Galvanized Steel: Common for fireproof applications due to high mechanical strength and fire resistance. Hot-dip galvanization adds corrosion protection.
• Stainless Steel: Offers superior corrosion resistance and is suitable for outdoor or corrosive environments.
• Aluminum Alloy or Fiberglass-Reinforced Plastic: Used in high-humidity or corrosive environments; some types provide fire resistance but may have lower mechanical strength compared to steel.

Standards and Compliance

• National and international standards include BS EN 61537, NEMA, and ISO/IEC 11801-1:2017.
• Fireproof cable trays must meet mechanical strength requirements to prevent deformation under full load and comply with fire safety regulations.
• CE marking or equivalent certification ensures compliance with European or national directives .

Selection Guidelines

• Choose tray thickness according to cable weight, number of cables, and environmental conditions.
• For heavy-duty or industrial applications, 2 mm to 6 mm steel trays are recommended.
• Ensure proper installation with splice plates, grounding jumpers, and secure mounting to maintain fireproof integrity . These manufacturers and specifications provide a reliable starting point for sourcing fireproof cable trays that meet national standard thickness requirements and safety regulations.
