two large rolling doors

You would be absolutely attracted by the two large special rolling doors which are close to the main entrance and can be seen with a  single glance after walk in if you come to visit Dingyan recently.It is in rolling type with plastic material ,upper half in transparent and yellow for the lower half part.It looks like two huge paintings when fully stretch out down to the ground,and we cant see the workshop inside there at the main entrance in that case.There comes next to it a small door which allows to get in and out.

As it is fully closed by the two huge doors but day light can shine through the upper transparent part,it feels like to be a special place after walk in through the small door.All the materials are kept in order,all the machines are running,all the people are focusing on their work.

Why install these two large doors?It is heatwave outside with high temperature in current summer days,it can help block most heat outside and keep the inside space cooler with additional fan blowing.

This is what we are thinking of all the time for our people to make them happy and feel  comfortable.

The devil is in the details.
