How to Pack Heavy Industrial Goods for Road and Rail Freight in India

Heavy industrial goods — machinery components, fabricated structures, heavy castings, industrial equipment — are the most demanding packaging challenge in domestic freight. A 200 kg casting that bounces loose in a truck for 800 kilometres arrives with impact damage. A palletised load that topples on a rail wagon destroys everything below it.

This guide is for manufacturers, engineering companies, and freight teams handling heavy goods dispatch within India.

When to Use Wooden Crates vs Corrugated Boxes

The decision point is weight:

Under 20 kg per item: 5-ply corrugated box is sufficient for most domestic road freight applications. Ensure burst factor is appropriate for the weight.

20 to 100 kg per item: Wooden export crates or heavy-duty wooden boxes are required. Corrugated boxes will not hold structural integrity under this weight during the vibration and impact loads of road freight.

Above 100 kg per item: Wooden crate with integrated pallet base. 4-way forklift entry required. 25 to 32mm timber minimum.

Wooden Crate Specifications for Heavy Goods

Timber Selection

Pine wood (silver wood): Good strength-to-weight ratio. Standard for most domestic industrial applications under 500 kg.

Hardwood (teak, sal, or mixed hardwood): Higher density and compressive strength. Required for loads above 500 kg or where the crate will be stored outdoors.

Plywood panels: Used for the wall panels of wooden crates. 9mm plywood for loads under 100 kg, 12mm for 100 to 300 kg, 18mm for above 300 kg.

Crate Construction

Base: Timber runners (75 x 75mm minimum for loads above 200 kg) with a plywood deck. The base carries the full load of the contents plus the stack load above. Do not underspecify the base.

Walls: Framed timber with plywood sheathing. Corner posts are the critical load-bearing elements — size them for the compressive load of stacked contents.

Lid: Screwed or bolted, not nailed. Screwed lids are removed without damage to the crate or contents. Nailed lids require prying that often damages the product.

Internal blocking: Timber blocks cut to size and screwed to the crate floor, surrounding the product base. The product should not be able to shift more than 10mm in any horizontal direction inside the crate.

Foam cushioning: 25mm EPE foam sheet on the crate base (between product and plywood floor), 15mm on all four sides and lid contact surfaces.

Pallet Specifications for Heavy Road Freight

For palletised heavy loads in domestic road freight:

Pallet size: 1000 x 1200mm industrial pallet for most Indian truck widths. 800 x 1200mm Euro pallet for standardised supply chains.

Timber: 75 x 100mm hardwood stringers for loads above 500 kg. 75 x 75mm pine for loads under 500 kg.

Entry: 4-way entry preferred for flexibility in truck loading and warehouse handling.

Load distribution: The pallet load should be evenly distributed. Never stack all weight on one corner or one stringer — this causes pallet failure under the off-centre load.

Maximum load: Standard industrial pallet carries 1,500 kg dynamic (moving on forklift) and 2,000 to 2,500 kg static (stationary). For heavier loads, specify reinforced heavy-duty pallet.

Securing Heavy Goods in Trucks

PP Strapping

19mm PP strapping is the minimum for heavy pallets and crates on road freight. Apply:

Two horizontal straps around the long axis.

Two horizontal straps around the short axis.

Always use angle boards at all four corners before strapping.

Steel Strapping

For loads above 1,000 kg or high-value cargo: steel strapping provides higher breaking strength than PP and does not elongate under sustained load. Requires steel strapping tool and steel seals.

Wooden Chocking

For wooden crates loaded in trucks: nail or bolt timber chock blocks against the base of the crate on all four sides to prevent sliding. This is particularly important for heavy goods where inertia loads during braking are high.

Lashing Straps

Ratchet lashing straps run from load anchor points to the truck D-ring lashing points on the truck floor. Use a minimum of 4 lashing straps for any load above 500 kg.

Rail Freight Packaging Considerations

Rail freight in India involves more vibration and impact loads than road freight due to rail joints, shunting operations, and coupling impacts. Key differences in packaging for rail:

Anti-vibration blocking: Internal timber blocking in wooden crates must be more substantial for rail — the product should not move even under sustained high-frequency vibration.

No protrusions: Rail wagon loading platforms have height restrictions. Ensure no part of the packaged goods protrudes above the wagon side walls.

Weather protection: Open rail wagons expose cargo to rain. All goods on open wagons must be covered with HDPE tarpaulin sheeting secured over the load.

Frequently Asked Questions

What is the weight threshold for switching from corrugated boxes to wooden crates?

Switch to wooden crates for individual items above 20 kg. Corrugated boxes lose structural integrity under sustained vibration at this weight, particularly over long road freight routes above 500 kilometres.

What timber thickness is needed for a wooden crate carrying 300 kg?

Use 12mm plywood wall panels with 50 x 50mm framing timber for 100 to 300 kg loads. Base runners should be 75 x 75mm hardwood minimum. For loads above 300 kg, increase to 18mm plywood panels and 75 x 100mm hardwood base runners.

How many PP strapping bands does a heavy pallet need?

For pallets above 500 kg: minimum 4 PP strapping bands — two around the long axis and two around the short axis. Use 19mm PP with metal seals for loads above 500 kg. Always use angle boards at pallet corners before strapping.
