All the above wind power blades have been installed successfully in north America, Canada, Australia and etc for over 3 years!!

What the craft does our factory use ?

As you know, there are 3 diffirent techniques to made fiber glass wind blades, the worst is hand lay-up( the cost is the cheapest, the quality is the worst), the better is RTM(ResinTransferMolding, the cost is cheaper, the quality is worse), the best is VARTM(Vacuum Assisted ResinTransferMolding, the cost is highest, the quality is the best).

SGSG is now using VARTM technique, which is the best scenario.

What kind of raw materials does the factory use ?

Different raw materials lead to different quality wind blades. SGSG now is all kinds of top quality materials as our main material. When you choose other company, I suggest that you can ask what kind of raw materials they are using now.

Why do we prefer to high quality wind blades?

If the quality of wind blades is not so good, we believe the loss suffered must be higher than the cost of replacing 1 new set wind blade. Thus we are willing to provide high quality wind turbine blades to our customers.

there are two common collaboration processes:

Method 1:

Shanghai Good Serve (SGSG) and Client sign NDA → Client provides SGSG with requirements → SGSG designs products and makes sample →

→ if satisfied → GT starts mass production
Client tests sample →
→ if unsatisfied → GT redesigns and make further samples until Client is satisfied
and mass production follows

Method 2:

SGSG and Client sign NDA → Client provides SGSG with design and specifications → SGSG makes sample for Client → if products meet specifications, SGSG start mass production.
