Product Features
Standard support spacing: 4 m to 6 m (can be customized up to 8 m for light loads).
Reduces the number of support structures, saving material, labor, and installation time.
Ideal for crossing roads, workshops, or open yards where intermediate posts are not allowed.
Reinforced side rails (often 200 mm to 300 mm height) and thicker sheet metal (2.0 mm, 2.5 mm or 3.0 mm) provide exceptional bending strength.
Rigorous static load testing ensures safe performance under heavy power cables, multiple layers, or bundled conductors.
Open Ladder Design for Heat Dissipation
The rung‑type open structure allows free air circulation, preventing heat buildup from high‑current cables.
Easy visual inspection, cable addition, and maintenance without dismantling the system.
Corrosion Resistance for Long Service Life
Available with multiple surface treatments (hot‑dip galvanized, powder coated, aluminum, stainless steel) to match various environmental conditions – from dry indoors to coastal or chemical atmospheres.
Customizable Rung Spacing & Length
Rung spacing typically 300 mm as standard; can be reduced to 200 mm or 250 mm for additional cable support.
Standard single section length: 4 m, 6 m; non‑standard lengths up to 8 m available on request.
Material Options
We offer four primary material choices for large span cable ladders, each suited to specific working conditions:
|
Material |
Surface / Finish |
Key Advantages |
Typical Environment |
|
Mild Steel (Q235B) |
Hot‑dip galvanized (≥65μm) |
High strength, cost‑effective, excellent outdoor corrosion resistance |
General outdoor, power plants, pipe racks |
|
Mild Steel (Q235B) |
Electrostatic powder coating |
Smooth appearance, UV‑resistant, fire‑retardant |
Indoor industrial buildings, warehouses |
|
Aluminum Alloy (6063) |
Mill finish or anodized |
Lightweight (1/3 of steel), naturally anti‑corrosive, non‑magnetic |
High‑rise buildings, weight‑sensitive roofs, marine interiors |
|
Stainless Steel (304/316L) |
Mill or passivated |
Ultimate resistance to acids, alkalis, salt spray |
Chemical plants, coastal outdoor, food processing |
All steel‑based ladders are fabricated from prime grade material, with welded rungs fully coated (inside and out) to prevent hidden rust. Large span sections are typically 2.0 mm – 3.0 mm thick, with optional reinforcing ribs for extreme loads.
Why Choose Us?
Engineering & Customization Expertise
We do not simply cut standard trays to length. Our engineers calculate the exact load‑deflection curve based on your span distance, cable weight, and environmental factors.
Free technical support for support spacing design, expansion joints, and seismic bracing.
Strict Quality Control
Every batch undergoes:
- Dimensional inspection (width, height, length, rung spacing)
- Coating thickness test (magnetic gauge for galvanized/powder coated)
- Load deflection test (simulating 150% of rated load)
- Weld penetration check (for rung‑to‑rail joints)
- All products are traceable with mill certificates and inspection reports.
Complete Accessory System
We supply matched large‑span connectors (splicing plates with double rows of bolts), heavy‑duty cantilever brackets, expansion clips, and grounding jumpers – everything needed for a turnkey installation.
Export‑Ready Packaging
Ladders are stacked with cushioning layers, placed on ISPM‑15 fumigated wooden pallets, and wrapped with stretch film for moisture protection.
Clear labeling (specs, weight, origin) and full documentation (CoC, packing list, quality report) are included, meeting international shipping standards.
Competitive Lead Time & Value
Standard sizes (6m span, 2.0mm, hot‑dip galvanized) are kept in stock.
Custom orders: 15–25 days after drawing approval.
Direct factory pricing without middleman markup.
Conclusion
- When your cable routing requires long distances between supports, heavy load capacity, and lasting corrosion protection, a standard tray simply will not suffice.
- Our Large Span Cable Ladder is purpose‑built to solve these challenges. From robust material selection and precision fabrication to comprehensive accessories and export packaging, we deliver a reliable, cost‑effective solution that reduces installed cost and extends system life.
- Contact us today with your span length, cable load, and environmental conditions – we will provide a detailed proposal and load calculation within 24 hours.
