Frequently Asked Questions
-
Each Indotray HQ plastic core tray is designed specifically for HQ diamond drill core with a nominal core diameter of 63.5 mm.
-
The tray has 4 individual rows, with approximately 1 metre of core per row.
-
Total drill core storage capacity is 4 metres per tray.
-
The heavy-duty 4-row layout for larger HQ drill core keeps core samples organized for geological logging, photography, sampling, transport and long-term core storage.
-
This makes it suitable for mineral exploration companies, diamond drilling contractors, mining projects and geological core libraries.
-
-
Overall tray dimensions: 1075 × 375 × 85 mm.
-
Core compatibility: HQ, nominal core diameter 63.5 mm.
-
Configuration: 4 rows with a total capacity of 4 metres of drill core.
-
Material: high-strength PP Copolymer construction with UV stabilization.
-
All Indotray BQ, NQ, HQ and PQ trays share a common 1075 × 375 mm footprint, supporting cross-size stacking and organized core shed storage.
-
The tray incorporates drainage, ID tag locations, measurement markings, lifting handles and reinforced structural features.
-
-
The Indotray HQ core tray is engineered to safely support a 60 kg fully loaded 4-metre HQ drill core during normal field handling and core storage.
-
Actual loaded weight varies significantly with rock density, mineralization, moisture and recovery, so a single core weight should not be assumed for every project.
-
High-strength PP Copolymer, reinforced ribs, thick outer support walls and the tray geometry distribute the core load across the structure.
-
The design is intended to minimize bending, twisting and sagging when the tray is correctly supported and handled.
-
For tenders or projects requiring a certified maximum load in kilograms, Indotray can provide the applicable technical/test information rather than relying on a generic rock-weight estimate.
-
-
The exact number of trays per 20-ft, 40-ft or 40-ft High Cube container depends on the packing configuration, palletization, nesting arrangement and whether lids, separators, ID tags or other accessories are included.
-
For bulk export orders, Indotray can prepare a container loading plan to maximize the number of plastic core trays per shipment and reduce freight cost per tray.
-
As a standard tray only configuration, for 20 Ft Container – 1050 Nos. and for 40 Ft Container – 2100 Nos
-
For website use, publish an exact container quantity only when it matches the current verified Indotray packing and dispatch configuration.
-
-
Using the Indotray Column Support System, up to 10 trays can be column-locked together for organized storage.
-
Reinforced corner locations support the column-locking arrangement and help maintain alignment of the stacked trays.
-
The stackable design is intended for core sheds, warehouses, field camps and long-term geological core storage.
-
A universal stackable lid can be used as part of the storage system.
-
Safe stacking in practice should always consider the loaded core weight, floor condition, storage environment and site handling procedures.
-
-
Yes. Indotray HQ plastic core trays are manufactured with UV-stabilized polymer for outdoor mineral exploration and core storage environments.
-
UV stabilization helps protect the polypropylene against degradation caused by prolonged exposure to sunlight and ultraviolet radiation.
-
This is particularly important for open core yards and exploration projects in high-UV regions such as Africa, the Middle East, Australia, India and South America.
-
The UV-stabilized construction helps support longer service life while maintaining tray strength, handling performance and dimensional stability.
-
Indotray core trays are designed for demanding field exposure, but good storage practice is still recommended wherever practical for maximum service life.
-
-
The Indotray HQ core tray uses a reinforced structural design developed specifically for the weight of diamond drill core.
-
Robust ribs underneath and around the core cavities help distribute load and resist twisting and sagging.
-
Outer support/skirting sections are designed with increased thickness, while reinforced corners provide additional stiffness and support for stacking.
-
The high-strength PP Copolymer construction combines impact resistance with the flexibility needed for repeated field handling.
-
The 4-row geometry supports the HQ core securely and helps spread the load instead of concentrating it at a few points.
-
Together, these features provide the high load-bearing capacity required for mineral exploration, core logging, transport and long-term drill core storage.
