Core Features
the final view of project
1. Stable Structure & High Load Capacity
Residential model: single‑layer load 30‑80kg.
Heavy‑duty industrial/commercial model: >500kg.
"Frame + shelf" design with punched‑in ribs prevents collapse.
2. Durable, Damage‑Resistant, Long Life
Galvanized + powder coated – 5‑10 years in humid environments (wood: 2‑3 years).
Cold‑rolled steel (hardness HB180‑220) resists impact, wear, moisture, mold, insects.
3. Flexible Adjustability for Wide Scenarios
Shelf spacing adjustable 3‑10cm – fits different item heights.
Residential: tool‑free assembly/disassembly. Industrial: bolt assembly – suitable for home, commercial, industrial use.
4. Eco‑Friendly & Easy to Clean
100% recyclable metal, no harmful substances.
Smooth surface – wipe with damp cloth. Ideal for kitchens, laboratories, clean environments.
Material Selection
1. Material Selection
Cold‑rolled steel: cost‑effective, 20‑30% harder than hot‑rolled – home & light commercial.
Stainless steel (304/201): high corrosion resistance, 1.5‑2× cost – humid/corrosive environments.
Aluminum alloy: lightweight (⅓ steel density), load ≤50kg – light mobile racks.
2. Forming
Cutting: CNC shearing, tolerance ≤±0.5mm.
Stamping: reinforcement ribs (increase load ≥30%) and mounting holes.
Bending: CNC, angle tolerance ≤±1° – prevents assembly misalignment.
3. Connections
Welding: weld tensile ≥300MPa – heavy‑duty, non‑detachable.
Detachable: clips (small racks), bolts (load 80‑150kg, medium racks), latches (adjustable, load ≤50kg).
4. Surface Treatment
Galvanizing: 5‑20μm zinc layer – hot‑dip for outdoor, electroplating for indoor.
Powder coating: 60‑120μm, 48h salt spray test, multiple colors – home use.
Brushed: for stainless steel, enhances quality, reduces fingerprints.
5. Quality Inspection & Assembly
Dimensional check – prevents loosening or skewing.
Load test: 1.2× rated load, 24h – no deformation.
Appearance: coating, weld joints, edges – safe to use.
Products Description
The metal rack – high load capacity, long life, high flexibility – comes from the combination of materials and craftsmanship. When selecting a metal rack, focus on materials, surface finish, and connection methods. Future products will evolve toward lighter weight, higher load, personalization, and smart applications.
