Frequently Asked Questions
Procurement Questions Answered by Racking Engineers
Everything Sri Lankan warehouse operators need to know about structural load capacities, customs clearance, shipping lead times, and on-site assembly.
Why is wire mesh shelving preferred over timber or solid steel in Sri Lanka?
Sri Lanka’s tropical climate consistently features relative humidity levels above 80%, particularly in coastal industrial areas like Peliyagoda, Kelaniya, Wattala, and Katunayake. Solid plywood decking absorbs airborne moisture, warping under load, harboring termites, and cultivating fungal spores that contaminate packaged goods (such as Ceylon tea bags and export garments). Solid steel sheets trap moisture beneath inventory and create thermal barriers that obstruct overhead fire sprinkler systems. HEDA's industrial wire shelving provides over 70% open area, allowing continuous 360-degree ventilation, zero moisture pooling, clear downward sprinkler penetration compliant with NFPA 13, and maximum light visibility.
How long does shipping take from your factory to the Port of Colombo?
Production typically takes 15 to 25 days depending on project tonnage and custom color requirements. Once loaded at our Guangzhou factory into 20GP or 40HQ seaworthy containers, sea freight transit time on direct maritime routes from Guangzhou/Shenzhen to the Port of Colombo (SAGT/CICT/JCT) is approximately 10 to 14 days. We provide tracking, BL documentation, and early advance packing manifests for swift pre-clearance with your local clearing agent.
Can your racking systems support both Asian and Euro pallet dimensions?
Yes. Our selective and heavy-duty racking systems are custom engineered around your exact pallet footprint. Whether your logistics facility utilizes standard Asian/Australian pallets (1200 mm x 1000 mm), Euro pallets (1200 mm x 800 mm), or specialized garment fabric roll skids, we design the clear beam entry spans (e.g., 2300 mm, 2700 mm, 3300 mm, or 3900 mm) and frame depths (typically 800 mm to 1100 mm) to maintain safe pallet overhangs and clearance tolerances per EN 15620 guidelines.
Do you provide structural calculations and PE-stamped layout proposals?
Yes. Our in-house engineering department generates comprehensive AutoCAD 2D floor plans, 3D structural models, and load-deflection calculation reports referencing European EN 15512 and FEM 10.2.02 codes. These documents clearly establish upright frame buckling resistance, beam deflection limits (1/200th span), baseplate anchor pull-out ratings, and permissible floor slab bearing pressures for submission to your structural consultant, building landlord, or BOI approval committee.
How do you support installation and assembly across Sri Lanka?
Every shipment is packed with clear, color-coded component tagging, step-by-step 3D assembly manuals, and comprehensive bolt/anchor torque charts. Because our racking utilizes precision CNC-punched hook-in beam connectors and rivet locks, local warehouse teams can assemble them rapidly with minimal equipment. For large distribution centers or multi-tier structural mezzanines exceeding 1,000 square meters, we can dispatch on-site bilingual installation supervisors or provide live remote video guidance to ensure flawless assembly.
What surface coating prevents rust in high-salinity zones near Colombo Harbor?
For high-salinity and corrosive coastal zones within 10 km of the coastline, we apply our specialized 10-stage industrial finish: hot alkaline degreasing, ultrasonic acid pickling, nano-ceramic zinc phosphating, deionized water rinsing, and electrostatic thermoset epoxy-polyester copolymer powder coating cured at 200°C. For extreme cold storage or outdoor covered staging yards, we also offer hot-dip galvanizing (HDG) compliant with ISO 1461, ensuring over 20 years of rust-free operational life.
What is the minimum order quantity (MOQ) and sample policy?
For standard light-duty wire shelving units and boltless racks, our MOQ starts from as low as 10 sets. For custom industrial pallet racking projects and mezzanine platforms, we provide complete engineering design and fabrication for single warehouse bay systems up to 500+ ton turnkey multi-bay distribution centers. Material samples (upright sections, beam cutouts, wire mesh decking swatches, powder coating color plates) can be air-couriered to your office in Colombo within 4 to 6 business days.
