Heavy-Duty 5-Ply & 7-Ply Industrial Corrugated Containers for Demanding Freight
ARUL RK ENTERPRISES engineers and manufactures high-strength industrial supply boxes and bulk packaging systems built specifically for automotive OEMs, heavy machinery builders, foundry castings, and international freight handlers. Manufactured at our Hosur plant (adjacent to SIPCOT Phase I & II industrial zones), our containers provide a cost-effective, 100% recyclable alternative to cumbersome wooden crates while delivering compression strengths exceeding 2,500 kgf.
Industrial components such as crankshafts, transmission gears, electric motors, hydraulic pumps, and machined brake rotors subject packaging to severe concentrated point loads, vibration harmonics, and vertical stacking pressure. We counter these forces using heavy double-wall (5-ply BC/BB) and triple-wall (7-ply AAC/AAA) corrugated board fabricated from high-tensile virgin softwood kraft linerboards (200 to 400 GSM) and reinforced fluting mediums bonded with cross-linked starch resins.
Structural Formats & Heavy-Duty Engineering Features
We manufacture industrial packaging tailored to specific automated assembly line staging, forklift handling, and sea-freight container consolidation:
- Timber-Replacement 7-Ply Triple-Wall Cartons — Reduces gross freight tare weight by up to 65% compared to wood crates
- Octabins & Bulk Sleeve Pack Systems engineered for granular plastics, masterbatches, and bulk fastener shipments
- Copper-Coated Steel Wire Stitching (double-stitched joints) delivering 40% higher joint tensile strength than adhesive tape
- VCI (Vapor Corrosion Inhibitor) Linerboard Integration to prevent surface oxidation on precision ferrous metal parts
- Full Overlap Flaps (FOL) & Telescopic Cap-Tray designs engineered for stacking payloads up to 1,000 kg per container
- Integrated Drop-Down Loading Flaps for ergonomic access during automotive assembly line kitting
Heavy-Duty Construction Matrix & Lab Testing Standards
We subject our industrial boxes to stringent testing protocols under IS 2771 (Part II) and ASTM D4169 standards to ensure zero creep or side-wall buckling under dynamic warehouse stacking:
| Structural Grade | Wall Architecture | Grammage (GSM) Profile | Edge Crush Test (ECT) | Max Dynamic Payload |
|---|---|---|---|---|
| Grade A (Machined Castings) | 5-Ply Double Wall (BC Flute, 7.0mm) | 200K / 150F / 150K / 150F / 200K | 8.5 – 11.0 kN/m | Up to 120 kg |
| Grade B (Automotive Assemblies) | 5-Ply High-Density (BB Flute, 6.2mm) | 250K / 180F / 180K / 180F / 250K | 11.5 – 15.0 kN/m | Up to 250 kg |
| Grade C (Heavy Equipment & Pumps) | 7-Ply Triple Wall (AAC Flute, 12.5mm) | 300K / 180F / 200K / 180F / 200K / 180F / 300K | 16.0 – 22.0 kN/m | Up to 600 kg |
| Grade D (Bulk Octabin & Timber Replacement) | 7-Ply Ultra-Heavy (AAA Flute, 15.0mm) | 350–400 Virgin Softwood Kraft Combinations | 24.0 – 32.0+ kN/m | Up to 1,000+ kg |
Engineered for Hosur's Heavy Manufacturing Ecosystem
Hosur is home to commercial vehicle giants, precision CNC machine builders, forging plants, and Tier-1 automotive systems manufacturers. ARUL RK ENTERPRISES acts as a direct Tier-1/Tier-2 packaging partner, providing:
- Automotive Powertrain & Transmission: Customized heavy-duty cartons with internal slotted timber/corrugated saddles for steering gearboxes, axles, and clutch plates.
- Electrical Switchgear & Control Panels: Die-cut high-density inner inserts combined with 5-ply outer shippers that pass vibration resonance testing.
- Foundry & Forging Components: Puncture-resistant heavy-gauge boxes capable of withstanding rough handling of iron castings and hot-rolled forgings without bottom burst.
- Export Bulk Shipments: Completely ISPM-15 exempt packaging allowing immediate clearance through North American and European ports without quarantine fumigation delays.
