1.What are the advantages of using color-coated coils to make logistics turnover boxes?
Lightweight and Cost-Effective:
Compared to metal crates welded from thick steel plates, crates made from thin-sheet pre-coated steel coils are significantly lighter. This translates to reduced fuel consumption and transportation costs in logistics.
The material cost itself is also typically lower than that of thick steel plates.
Excellent Corrosion Resistance:
The coating of the pre-coated steel coils (polyester, silicone-modified polyester, PVC plastisol, etc.) provides effective protection for the substrate, making it resistant to corrosion from moisture, chemicals (such as cleaning agents), and general scratches. This is crucial for crates used in humid environments or in industries such as food and chemicals.
Aesthetics and Identifiability:
Pre-coated steel coils are available in a variety of vibrant colors. Businesses can use different colors to categorize crates, identify different product lines, destinations, or priorities, improving logistics efficiency.
Clean, tidy, and brightly colored crates also contribute to a better corporate image and improved 5S management practices in warehouses and workshops.
2.What are the typical structures and processes of color-coated roll logistics turnover boxes?
Container Frame: A skeleton is formed by bending relatively thick color-coated steel rolls (e.g., 0.4mm-0.8mm) to ensure structural strength.
Panels: The container walls may use thinner color-coated steel sheets.
Connection Methods: Primarily using riveting, screw connections, or snap-fit designs to avoid welding.
Internal Protection: To prevent scratches on transported items, the inner walls of the container are often lined with plastic or EVA foam.
Reinforcing Ribs: Reinforcing ribs are pressed into the container body through a bending process to ensure sufficient structural strength while reducing weight.
3.What are the advantages and disadvantages of color-coated roll turnover boxes compared to plastic turnover boxes?
Weight: Color-coated roll turnover boxes are lighter; plastic turnover boxes are the lightest.
Strength/Durability: Color-coated coil turnover boxes have better strength, but are susceptible to deformation under heavy pressure; plastic turnover boxes have good impact resistance, but are prone to aging and becoming brittle.
4.What are some applicable scenarios?
Light to medium load capacity: Not suitable for supporting extremely heavy metal components.
High-value or fragile items: Such as automotive parts, electronic components, precision instruments, etc.
Industries requiring high cleanliness: Such as the food, pharmaceutical, cosmetic, and electronics industries.
Modern warehouses requiring color management.
5.What are the precautions?
Edge Protection: Cuts made after trimming and bending expose the metal substrate, creating a starting point for corrosion. High-quality manufacturers use edge sealing adhesive or plastic edge banding to seal and protect the edges.
Avoid Excessive Impact: Although the coating has a certain degree of toughness, a violent impact from a sharp object can still scratch the coating, leading to rust on the substrate.
Design Rationality: The structural design must be rational, ensuring overall rigidity and stacking capacity through reinforcing ribs and other means to prevent deformation that could cause the door to fail to open or close, or unstable stacking.
