Warehouse Storage Metal Steel Gravity Carton Pallet Flow Rack Flow Racking System

Product Description

Gravity Flow Rack (Pallet Flow / Carton Flow)

Suhong's gravity flow rack is engineered as a true FIFO (First-In, First-Out) high-density storage system that moves pallets or cartons automatically from the loading side to the picking side using gravity alone. Built with heavy-duty structural steel frames and inclined roller or wheel tracks set on a controlled decline pitch, it ensures the oldest stock is always picked first, with no manual stock rotation required. As a direct source factory, Suhong delivers custom-engineered configurations at competitive pricing, with reliable load capacity and long-term durability for demanding, high-turnover warehouse environments.

Specification

Applications
Food & Beverage: Perishable and date-sensitive product storage requiring strict FIFO rotation
Cold Storage & Distribution: High-density pallet storage with automatic stock rotation
Manufacturing: Production line replenishment, assembly feed, and parts supply
3PL & Logistics Centers: Dock staging, pallet intake, and empty pallet returns
E-commerce & Order Fulfillment: Carton flow for fast, accurate piece and case picking

 
Manufacturing Process

Material Selection: High-strength Q235B/Q355 structural steel columns and beams, tested for yield strength and thickness tolerance

Cutting & Punching: CNC laser cutting and CNC punching for precision column, beam, and track-mounting connection points

Roll-Forming: Precision roll-forming of track rails and roller/wheel bed components to tight tolerance for smooth, controlled pallet or carton flow

Welding: Robotic and manual MIG welding for column-to-base joints and track support brackets, followed by weld inspection

Surface Treatment: Shot blasting to remove scale and rust, followed by degreasing and phosphating

Finishing: Electrostatic powder coating (indoor use) or hot-dip galvanizing (cold storage/corrosive environments)

Quality Inspection: Load testing, decline pitch and flow-speed verification, dynamic brake function checks, weld strength verification, and dimensional verification against RMI/ANSI MH16.1 standards

Packaging: Bundled and wrapped for container loading, with protective corner guards to prevent transit damage

Key Configurations

Frame: High-strength structural steel columns and beams, standard pallet rack structure adapted to hold inclined flow lanes

Flow Track: Galvanized steel rollers, full-width polycarbonate wheels, or staggered wheel tracks, selected per pallet or carton type and load weight

Decline Pitch: Engineered incline from the loading (rear) end to the picking (front) end, adjustable to control flow speed and prevent product damage

Speed Control: Dynamic brakes and speed controllers integrated into the track to regulate pallet speed and ensure safe, consistent handling

Lane Depth: Pallet flow lanes 2 to 20+ pallets deep; carton flow lanes sized to SKU and replenishment cycle

Safety Features: End-of-lane stops, lane guides/dividers for SKU separation, and anti-rollback devices

Configuration: Pallet flow (forklift-loaded, full pallet handling) or carton flow (manually loaded, case/tote/bin picking)

Finish: Powder-coated or hot-dip galvanized for indoor, cold storage, or corrosive environments

Capacity: Engineered per pallet position up to 4,000+ lbs; carton flow rollers rated up to 50 lbs/sq ft for consistent case and tote loads

FAQ

Q: What is your maximum monthly production capacity, and what percentage is currently utilized?
A: Suhong Storage Rack operates multiple advanced production lines to ensure scalable, high-volume output. Our monthly production capacity varies by product specifications and rack configuration. We actively manage factory utilization to maintain a perfect balance between manufacturing efficiency and operational flexibility, allowing us to absorb peak demands and urgent orders without increasing standard lead times.

Q: What is your Minimum Order Quantity (MOQ) per SKU, and are there price breaks for higher volumes?
A: Our standard Minimum Order Quantity (MOQ) is 1,000 kg (1 ton) for standard inventory items. For custom storage rack manufacturing, the MOQ is a minimum order weight equivalent to a standard 20-foot shipping container (20 tons). We offer volume-based tiered pricing; unit costs decrease accordingly as order volume increases. Sample orders are exempt from standard MOQs.

Q: How do you handle urgent or expedited production requests?
A: We prioritize urgent orders through agile production scheduling, dedicated resource allocation, and direct coordination with our manufacturing team to meet tight deadlines. Throughout the expedited manufacturing process, we provide transparent, real-time tracking updates to keep clients aligned.

Q: What is your lead time from order placement to ex-factory (ready for pickup)?

A: Our standard manufacturing lead time is 15 to 30 days from order confirmation and deposit receipt to ex-factory status. The exact delivery timeline depends on the rack type, total order quantity, custom engineering requirements, and our current production schedule.

Q: What specific quality control (QC) certifications do you hold, and can we review your latest audit reports?
A: Suhong Storage Rack maintains a strict international quality management system. We hold official ISO 9001, ISO 14001, CE, and SGS audit reports. We provide copies of our quality certifications upon request, and can share recent factory audit summaries subject to mutual confidentiality agreements.
