Category Overview

Metal storage racks deliver structural stability and flexible shelf adjustment for living rooms, pantries, garages, and commercial distribution. Produced from high-tensile cold-rolled steel, each racking unit undergoes continuous automated roll-forming, robotic MIG welding, and thermosetting powder coating. This execution ensures frame rigidity, surface protection, and non-wobbling stability under rated capacities. Standardized flat-pack carton design reduces overall transport volume for maximum ocean container utilization.

Core Specifications

Boltless Interlocking Frame

Rivet and slot connectors allow complete assembly without threaded fasteners or specialized tools.

38mm Height Increments

Vertical post slots feature 38mm adjustment spacing to accommodate objects of varying dimensions.

Roll-Formed Steel Uprights

Posts and support beams utilize 0.8mm to 1.2mm cold-rolled steel sheets to resist structural bending.

Epoxy Powder Coating

Surface finish resists surface scratches and moisture exposure after passing 48-hour neutral salt spray validation.

Logistics-Optimized Packaging

Nested component placement reduces individual carton volume by up to 35 percent.

Production Sequence

01/

Steel Coil Slitting: Cold-rolled steel coils undergo automated shearing into precise post and beam strip widths.

02/

Precision Punching: Progressive dies press interlocking slots into vertical posts without leaving edge burrs.

03/

Robotic Welding: Structural joints receive uniform continuous welds for consistent load distribution.

04/

9-Stage Surface Wash: Metal parts pass through multi-stage degreasing and zinc phosphating to create a rust-inhibiting base.

05/

Powder Application & Curing: Thermosetting powder spray cures at 200°C to lock in finish adhesion.

06/

Carton Packing: Components receive corner protection, nested placement, and outer corrugated boxing.

Engineering Customization

Dimension Adaptation: Custom height, width, and depth configurations tailored to specific storage layouts.

Load Rating Engineering: Steel gauge and beam profile adjustments to meet target loading requirements from 75kg to 250kg per tier.

Surface Texturing: Matte, fine-textured, or glossy powder coating options matched to custom color specifications.

Private Label Packaging: Barcode placement, custom user installation guides, and brand carton printing.

Decking Material Options: Choice of steel plates, wire mesh panels, or high-density engineered wood boards.

Quality Assurance Standards

Raw Material Checks: Thickness tolerance measured within ±0.02mm along with steel sheet tensile strength verification.

Static Load Testing: Shelf tiers support 1.5 times the rated capacity for 24 hours to record zero permanent deformation.

Coating Adhesion Audit: Cross-hatch cut testing performed according to ISO 2409 standards to prevent paint flaking.

Drop Packaging Validation: Cartons undergo 10-point corner and edge drop testing to ensure courier transit protection.

Manufacturing Advantages

Optimized Packing Density

Compact package layout increases unit quantities per 40HQ container, lowering ocean freight cost per unit.

Integrated In-House Lines

Complete control over forming, stamping, and coating stages delivers consistent dimensions and reliable lead times.

Verified Structural Integrity

Every production run adheres to strict load tolerances, salt spray resistance, and dimensional alignment checks.

Flexible Container Mixing

Support for combining multiple shelf sizes within a single container shipment simplifies inventory management.

FAQ

Q: What is the standard weight capacity per shelf tier?

A: Standard residential configurations support 75kg to 150kg per shelf. Units with bottom support ribs hold up to 250kg per tier under uniform load distribution.

Q: Can shelf heights be adjusted after full frame installation?

A: Yes. The boltless keyhole slots allow individual shelf beams to be unclipped and repositioned without disassembling the main vertical frame.

Q: How does the finish resist moisture and rust over time?

A: Steel components pass through a 9-stage cleaning and phosphating pretreatment before receiving thermosetting powder paint cured at 200°C.

Q: Are packages reinforced for drop-ship fulfillment?

A: Yes. Units ship in reinforced 5-ply outer cartons equipped with internal corner guards and foam buffers to withstand parcel shipping impacts.

Q: What is the production lead time for bulk container orders?

A: Samples take 7 to 10 days to complete. Full container production takes 30 to 35 days following final drawing approval.
