Galvanized Steel (GI) Core Boxes & Trays
Engineered from prime Tata and Jindal hot-dip Galvanized Plain (GP) steel sheets. Global Enterprises GI core boxes provide unmatched torsional rigidity, heavy-gauge sidewall reinforcement, and multi-decade corrosion resistance under demanding underground and open-pit exploration drilling conditions.
ALL GALVANIZED STEEL CORE BOX MODELS
Precision press-brake bent corrugated profiles tailored for standard diamond core drilling sizes: BQ, NQ, HQ, and PQ. Fully compatible with wireline exploration rigs worldwide.
GI Core Box Model BQ (7 / 6 Rows)
Fabricated specifically for BQ drill core samples (36.5 mm core diameter). Formed with deep precision channels to prevent core lateral movement and rattling during mine site haulage. Includes pre-punched drain slots in each trough for wash-water evacuation and moisture drainage.

GI Core Box Model NQ (5-Row)
The industry standard for gold, copper, zinc, base metal, and coal geological exploration across India and overseas. Accommodates 5 meters of standard 47.6 mm NQ core samples with rolled top lips that prevent hand abrasions during manual logging and sample handling. Over 100,000+ units delivered to leading mining corporations.
GI Core Box Model HQ (4-Row)
Engineered for 63.5 mm HQ drill cores utilized in geotechnical engineering, dam foundation drilling, tunnel investigations, and fractured core extraction. Built with high-profile side walls and rigid partition embossments to safely support heavy sample weight without bending.
GI Core Box Model PQ (3-Row)
Tailored for massive 85 mm+ PQ diameter cores commonly retrieved in large diameter geotechnical exploration, metallurgical bulk sampling, and deep strata logging. Features 92 mm individual slot width with reinforced corrugation for maximum payload endurance.
Full-Cover Protective Lids
Custom matching galvanized sheet lids fabricated in 22, 24, and 26 gauge. Featuring hemmed side lips that snap tightly over the core tray, protecting cores from weather exposure, rain wash, and contamination.
Core Depth Markers & Blocks
Precision plastic and wooden core recovery depth markers with flat writable faces for borehole numbers, from-to depths, core loss indications, and geological logging tags.
Pallet Nesting Stacking
Each GI tray is formed with precision end-profile return flanges that interlock with the box beneath, ensuring safe stacking up to 25 layers high on standard mining pallets.
