What should I Pay Attention to When Metal Storage Containers to Buy?

When metal storage containers to buy, you need to consider multiple dimensions such as material safety, structural design, and adaptability to usage scenarios to avoid quality risks, safety hazards, and cost overruns. The following are specific precautions and practical suggestions:

1. Material selection: core safety and performance guarantee

Food grade material certification

Stainless steel: 304 or 316 stainless steel is preferred, and 201 or industrial grade stainless steel is avoided.

Coating material: If the container is coated, it must be confirmed that it has passed the "National Food Safety Standard Enamel Products" test to avoid excessive lead and cadmium.

Industrial grade material adaptability

Carbon steel: Suitable for storage in dry environments, but requires rust prevention. If used in humid environments, 316 stainless steel or aluminum alloy must be selected.

Aluminum alloy: Lightweight and corrosion-resistant, but the strength is lower than steel, and it is not suitable for scenarios with a load of more than 500kg.

Special materials for hazardous goods

When storing flammable and corrosive liquids, UN-certified steel drums must be used, and the inner wall coating must be confirmed to be compatible with chemicals.

2. Structural design: balance between function and safety

Sealing verification

Food containers: the sealing ring is required to be food-grade silicone. Test method: fill water and invert for 24 hours without leakage, or the pressure gauge pointer is stable after vacuuming.

Industrial containers: check whether the flange connection is sealed with an O-ring, and the threaded interface needs to be equipped with a loosening prevention device.

Load-bearing and stability

Shelves: confirm the single-layer load-bearing capacity and check the connection method between the column and the beam.

Stacking containers: reinforcement ribs or grooves need to be designed at the bottom to ensure that stacking more than 3 layers does not tip over.

Humanized design

Opening and closing method: containers that are frequently used should choose quick-open locks instead of bolts; food cans are recommended to use wide-mouth design for easy cleaning.

Identification system: industrial containers need to reserve label positions, and food containers can be engraved with capacity scales.

3. Use scenario adaptation: avoid "one-size-fits-all" procurement

Environmental adaptability

Outdoor use: choose galvanized steel plates or powder spraying to avoid rust caused by the easy peeling of ordinary paint.

Low temperature environment: Aluminum alloy containers may become brittle below -50℃, and 304 stainless steel or special low temperature steel must be used instead.

Customization for special needs

Explosion-proof requirements: Containers for storing flammable dust must comply with ATEX standards and be equipped with pressure relief valves.

Clean room use: Select dust-free coating with surface roughness Ra≤0.4μm to avoid particle residue.

Optimization of space utilization

Storage shelves: Select layer height according to the size of the goods to avoid space waste.

Mobile containers: Carts with universal wheels must be equipped with brakes to prevent sliding and collision.
