Solid Bottom Perforated GI Cable Tray Hot Dip Galvanized Steel Dust Proof

Gi Perforated Cable Tray Solid Bottom

BENDIN Gi Perforated Cable Tray Solid Bottom is a galvanized cable support with a closed solid base instead of a perforated one. The solid bottom prevents dust, debris and small objects from falling through, making it suitable for dusty plants and areas where cable protection matters more than airflow.

Application and Functions in Different Scenarios

Core Functions

1. Efficient Heat Dissipation: the perforated base releases heat generated by loaded power, control and instrument cables, preventing overheating and extending cable service life.
2. Corrosion Protection: pre-galvanized and hot dip galvanized steel resists humidity, salt spray and industrial fumes so the tray stays reliable in demanding environments.
3. Organized Cable Routing: the channel separates power cables from signal cables, reducing electromagnetic interference to sensitive control instruments.
4. Fast Installation and Maintenance: the open perforated design allows quick cable laying, inspection, drop-out and later system expansion without complex civil work.
5. Solid Bottom Protection: the closed base keeps dust, debris and small objects away from cables in dusty environments.

Typical Application Scenarios

Dusty industrial plants and foundries.
Food and grain processing areas.
Outdoor sheltered cable routes.
Warehouses and logistics centers.
Areas requiring cable protection from below.

BENDIN Installation & Selection Considerations

1. Material and Surface Selection: evaluate the corrosive media on site and confirm pre-galvanized and hot dip galvanized steel with the correct surface treatment before ordering.
2. Avoid Galvanic Corrosion: never let dissimilar metals touch directly; use matching bolts and insulating gaskets between the tray and carbon steel brackets.
3. Load Calculation and Support Span: calculate the total cable weight to select the correct plate thickness and load class, and reduce the support span where heavy cables concentrate.
4. Thermal Expansion Control: install expansion joints on long straight runs to absorb thermal deformation caused by temperature changes.
5. Continuous Earthing and Bonding: keep continuous electrical bonding across all metal sections, mandatory in hazardous classified zones.
6. Separation of Power and Instrument Cables: use dividers to separate power cables from instrument cables and cut electromagnetic interference.
7. Cutting and Re-Protection on Site: cut with the correct tools and re-protect every cut edge and weld so the corrosion-resistant surface is restored.
8. Surface Inspection Before Installation: check the coating before installation, protect the surface during transport and repair any scratches that expose bare metal.
