Cable trays are used in the industrial plants to protect the laid cables. Specifically, the PS and AR perforated series are characterized by more lightness and by a good ventilation of the cable inside. The typology FC (closed bottom) is particularly suitable for environments where the cable isolation is essential.
Thermal expansion: Our joints with crossed slots allow an even greater deviation between the elements, recovering any possible expansion without damages.
Electrical continuity: The electrical continuity of the cable trays is guaranteed by the correct assembly of joints and/or the copper bonding jumper; for this purpose, properly marked grounding holes are made on the cable trays and cable tray accessories.

Spina Group offers a complete range of cable tray accessories and fixing components designed to simplify installation and ensure maximum stability for electrical and instrumentation systems.
Our range includes cable ladder accessories, joints, and fixing brackets that guarantee safe and quick assembly for all cable tray types, from perforated to ladder and wire mesh.
Among our most requested solutions are cable tray joints and expansion joints, which allow flexibility and compensate for thermal expansion, maintaining the alignment and mechanical strength of the system even under temperature variations.
The accessory line also includes separators, end edges, wall supports, and floor fixings, available in Hot-Dip Galvanised (HDG), stainless steel, and aluminium to ensure compatibility with all Spina Group cable tray systems.
Every fixing accessory is engineered according to European standards, offering durability, corrosion resistance, and ease of installation — the ideal choice for industrial and infrastructure applications.
Spina Group designs and manufactures cable ladders for industrial and infrastructure projects requiring reliable and ventilated support systems for electrical and instrumentation cables.
Each ladder tray combines high mechanical resistance and maximum ventilation, ensuring safe cable routing even in high-temperature environments. Thanks to their open structure, ladder cable trays are ideal for heavy-duty industrial applications where fast installation and accessibility are key.
Our cable ladder systems are available in Hot-Dip Galvanised (HDG) and stainless steel, with optional aluminium ladder trays for lightweight or corrosion-sensitive environments. Every model ensures full compatibility with Spina Group accessories and conforms to EN and UL standards.
Standard widths include 300mm ladder trays and larger custom sizes, offering flexibility for both compact and large-scale installations.
Accessories such as elbows, junctions, supports, and fixing systems guarantee complete modularity and safe installation in any industrial setting.
Spina Group designs and supplies cable tray covers to ensure complete protection of electrical and instrumentation cables from external agents such as dust, humidity, and mechanical impacts.
Our protective covers for cable trays and ladder trays are designed for indoor and outdoor environments, guaranteeing long-term reliability even in harsh industrial conditions.
Each outdoor cable tray with cover offers effective shielding against rain and UV exposure while maintaining proper cable ventilation. The covers are compatible with all perforated, ladder, and closed-bottom tray systems from Spina Group.
We provide ladder cable tray covers and fixing systems that allow quick installation and secure coupling without deformation. Covers are available in Hot-Dip Galvanised (HDG), stainless steel, and aluminium, matching the same materials and finishes as our cable tray product lines.
Custom sizes and thicknesses are available upon request to meet specific project requirements and environmental protection classes.
