Italian Hollow Cable Tray Specifications

Italian hollow cable trays are available in various types, materials, and sizes, designed to meet European and international standards for industrial and civil installations.

Materials and Finishes

Italian manufacturers produce hollow cable trays in hot-dip galvanized steel, stainless steel, Sendzimir zinc-coated steel, and aluminum, with some companies offering fiberglass-reinforced polyester (GRP) for specialized applications. These materials ensure corrosion resistance, mechanical strength, and long-term durability, suitable for demanding environments such as oil & gas, chemical, and food industries.

Types of Hollow Cable Trays

Hollow cable trays, often referred to as solid-bottom or closed trays, are designed to fully enclose cables, providing protection from dust, moisture, and mechanical damage. Italian manufacturers offer: Closed-bottom trays (FC type): Ideal for environments requiring complete cable isolation. Perforated trays (PS and AR series): Provide ventilation and reduce weight while maintaining structural integrity.

Ladder trays: Suitable for medium to large cables with high load requirements. Mesh trays: Lightweight, flexible, and allow easy cable routing and ventilation.

Dimensions and Customization

Standard widths range from 100 mm to 600 mm or more, with lengths typically around 3 meters, though custom sizes are available to meet specific project requirements. Manufacturers provide custom thicknesses, lengths, and joint designs to accommodate thermal expansion, load capacity, and installation constraints.

Load Capacity and Installation Features

Italian hollow cable trays are engineered for high load-bearing capacity, with joints and supports designed to handle thermal expansion and maintain electrical continuity. Grounding holes and copper bonding jumpers are included to ensure safe electrical continuity. Accessories such as brackets, supports, and fasteners are available for flexible installation layouts.

Standards and Certifications

Products comply with European (EN) and international (UL) standards, with CE marking and third-party certifications (IMQ, LCIE, UL) ensuring quality, safety, and regulatory compliance. Manufacturers also provide full documentation, testing, and after-sales support for industrial projects.

Applications

Hollow cable trays are widely used in industrial plants, infrastructure projects, energy facilities, and large civil installations, offering protection, organization, and efficient cable management in environments where mechanical protection and isolation are critical. Italian manufacturers such as Schiavetti Tekno (Spina Group), FEMI-CZ, and Sitie provide both standard and fully customized hollow cable tray solutions, ensuring compatibility with Unistrut systems and other modular supports.
