All members in our R & D team devote themselves to enhance and promote product's quality for achieveing as long as its used life span. 

For example, They have tried to make our G500 steel as hard as it should be, this process took us 1 year to achieve.

For Pre-painted steel, they did comparative test on each different experiment parameters to improve paint durability, so our life time of our PPGI is about 8-15 years, they also helped to find paint with less pollution.

For our glass wool, they did hard work to achieve the Low moisture absorption and stable physical properties.

For our Color powder coating, our engineers successfully come over with the technique difficulty and create Low tempreture powder coating, which could be consolidated at a low tempreture say about 160 cels degree by 15 minutes or 200 cels degree by 5 minutes, save energy largestly.
