1. Check the material of the warehouse shelves. Heavy duty shelves are
mostly produced from cold-rolled steel, but few truly meet the national
standard, mainly because most customers have a high sensitivity to price. The
simple way is to conduct a load-bearing experiment according to the pre agreed
shelf load. For example, a pre agreed upon three-layer shelf with a load-bearing
capacity of 2000kg per layer is used. Then, each household will make a sample
and go to the same place. 2000kg of goods will be placed on each layer according
to the agreement, and the shelf will be left to stand for a few days to observe
if it deforms. When the final batch production is carried out, it is sufficient
to inspect according to the samples.
2. Check the structure of the warehouse shelves. Observe whether the bent
and connected parts of the assembled sample shelf are even and have no obvious
gaps.
3. Look at the surface of the warehouse shelves. Observe the assembled
sample shelf to see if the surface spray treatment is uniform and has strong
adhesion, and observe whether there are any missing spray treatments in various
parts of the entire shelf, especially in areas with holes.
4. Check the welding process of warehouse shelves and shelves. Observe
whether the welding joint is uniform and full, preferably in a fish scale shape,
and also check for any areas of missed welding.
