Ranking of Tray-type Cable Trays in South Africa

Wire-mesh (basket) trays are the most commonly used, followed by perforated trays, with return flange trays typically used for aesthetic or showroom applications.1. Wire-Mesh (Basket) Cable TraysWire-mesh trays, also called basket trays, are the most widely used cable trays in South Africa, especially in server rooms, data centers, and exposed ceiling installations . They are lightweight, easy to install, and allow excellent airflow, which helps prevent overheating of cables. Wire-mesh trays are ideal for routing multiple cables in both horizontal and vertical applications and are often preferred for flexible and modular installations.2. Perforated Cable TraysPerforated trays are commonly used in industrial and commercial environments, such as factories and large buildings . They provide good ventilation for cables while offering more structural support than wire-mesh trays. Perforated trays are available in pre-galvanised, hot-dip galvanised, and stainless steel finishes, making them suitable for environments with mild to moderate corrosion exposure . They are often chosen for medium to heavy-duty applications.3. Return Flange Cable TraysReturn flange trays are typically used in showroom or exposed installations where aesthetics are important . They provide a clean, finished look while still supporting cable management needs. These trays are less common in industrial settings due to their higher cost and lower flexibility compared to wire-mesh or perforated trays.Material ConsiderationsPre-galvanised steel: Light-duty, suitable for indoor environments with minimal corrosion .Hot-dip galvanised steel: Medium to heavy-duty, ideal for more demanding environments .Stainless steel (304/316): Best for corrosive or outdoor environments, offering maximum durability .Supplier Options in South AfricaMajor suppliers include Central Support Systems, Advanced Strut, Liteglo, and RS Components, offering a range of cable trays, accessories, and installation support across Johannesburg, Pretoria, Durban, Cape Town, and Namibia . These suppliers provide both commercial and industrial solutions, ensuring that the choice of tray type aligns with the specific application and environmental requirements.Practical Ranking SummaryWire-Mesh (Basket) Tray – Most popular, flexible, and cost-effective.Perforated Tray – Industrial/commercial use, medium to heavy-duty, good ventilation.Return Flange Tray – Aesthetic applications, less common, premium finish. This ranking reflects usage frequency, versatility, and suitability for different environments in South Africa.
