Qingdao Huading Imp. & Exp. Co., Ltd. has built a complete and mature production and inspection process, from the raw materials procurement, the finished products inspection to final product quality tracking, comprehensive monitoring product quality. With chemical analysis department, the physical inspection department, service department, we treat products quality as the lifeblood of enterprise.

Now we briefly list work procedure as follows,

Before production process
* Raw material selection
1) We purchase virgin material only from PetroChina,Sinopec and similar level suppliers,so raw material quality is guaranteed from source.We also have fixed and reliable source for recycled material.
2) Raw material would be inspected strictly before entering factory by our own laboratory.We have all sets of test equipment and technologist to support it.

 After production process
* Five strict quality testing procedures: appearance view;specification measurement;weight measurement;load capacity test;impact resistance test and so on.
We list concrete content of each test procedures,
1) Appearance view:surface shall be level and smooth; no cracking and deformation;of unified hue; no clear color deviation for same batch of cargo; non-slip mat should be assembled; reinforced steel tubes shine ans amooth.
2) Specification measurement:    +3/-6 mm allowance
3)  Weight measurement:            ± 0.5KG
4)  Load capacity test: including static load test,dynamic load test and rack load test,at leat 48 hours.
5) Impact resistance test:Angle dropped down at least 3 times from shelf
