Industrial Pigeon Hole Racking System: Small-Parts Storage & Global Procurement Guide

An Industrial Pigeon Hole Racking System is a heavy-duty, compartmentalized steel storage structure engineered from Cold-Rolled Close Annealed (CRCA) sheet steel, organized into a matrix of individualized rectangular or square cells. Unlike plastic bin louvred panel systems which are prone to UV degradation, brittle fracture under impact, static buildup, and continuous sagging under heavy steel fasteners, steel pigeon hole racks offer structural permanence, non-combustibility, substantially higher load ratings (up to 150 kg per cell), and zero reliance on petrochemical plastics. Furthermore, pigeon hole systems offer continuous steel divider barriers that prevent small washers, pins, or electronic parts from slipping behind bins into inaccessible dead spaces.

The optimal aperture geometry is calculated based on three operational variables: the maximum SKU packaging volume (Width × Depth × Height), the required ergonomic retrieval clearance (typically adding 40 mm to 60 mm vertical and horizontal hand-reach allowance), and picking velocity. Standard industrial cells range from 150 × 150 mm up to 450 × 450 mm, with rack depths typically configured at 300 mm, 450 mm, or 600 mm. For manual hand picking, standard bay heights are maintained at 2,000 mm to 2,400 mm. For warehouse spaces with high ceilings, Divakaran integrates the pigeon hole framing directly into multi-tier catwalk mezzanines, extending vertical usability up to 8.5 metres with intermediate floor grating.

Yes. As an OEM manufacturer with automated CNC punching and roll-forming equipment in Umbergaon, Gujarat, we frequently fabricate asymmetrical or step-down pigeon hole matrices. For example, lower tiers can be configured with larger 400 × 400 mm compartments for bulky sub-assemblies or heavy motor components, transitioning into smaller 150 × 150 mm apertures at eye level for high-density micro-fasteners, relays, or terminal blocks. Both fixed permanently welded grids and fully adjustable slotted dividers are available.

Export orders to the Middle East, Canada, Sri Lanka, and Bahrain undergo specialised export-grade packing protocols. Upright frames, horizontal shelves, and dividers are flat-packed in high-density component bundles secured with heavy polyester strapping. Critical contact edges and corners are protected with thick heavy-ply cardboard guards. Bundles are enclosed within multi-layer polyethylene stretch film and sealed with anti-corrosion Vapor Corrosion Inhibitor (VCI) films to prevent moisture condensation during sea journeys. Palletized loads are mounted on heat-treated ISPM-15 compliant timber skids designed for seamless fork handling inside shipping containers.

All Divakaran steel racking undergoes a rigorous industrial pre-treatment process consisting of alkaline degreasing, water rinsing, pickling for scale removal, zinc phosphating, and demineralized rinsing. This surface conversion layer provides active galvanic protection. Components are subsequently coated with 60 to 80 microns of high-grade epoxy-polyester hybrid thermosetting powder, cured inside continuous convection ovens at 180°C–200°C. This finish exhibits outstanding scratch resistance, chemical tolerance against industrial lubricants, and complies with international ASTM salt-spray endurance thresholds.

Typical fabrication lead times for standard customized pigeon hole projects range from 2 to 4 weeks depending on overall tonnage and complexity. We regularly service both LCL (Less than Container Load) project consignments and full 20ft / 40ft FCL container export shipments. Full container load shipments allow international buyers to maximize freight value, and our layout engineering team provides 3D container packing load plans to ensure 100% volumetric container utilization.
