FAQ

What is a pre-engineered steel structure?

Pre-engineered steel structure means that the material is fabricated completely or partially in a factory, ready to be assembled on-site. There are many advantages to this building type and method. It is much faster than conventional building, as the fabrication takes place within a factory with the use of specialised equipment, and work is not dependant on the weather. On-site construction is also executed much faster, and it is less labour intensive.

Is your price competitive with other companies?

Our business objectives are to give the best price with same quality and best quality with the same price. We can try the best to cooperate with you to reduce your cost.

How do we cooperate on certain project?

Firstly, please send us your project details, your requirements and design proposal. Then we will make a quotation.Finally we make a deal.

Do you supply installation service?

Yes, we do. But you will pay for our professional installation cost in advance in accordance with the payment term confirmed by both of us, then we will send the engineers and construction workers to supervise it.

Can I have a visit to your factory before the order?

Why not? Welcome to visit our factory. You can fly to Shanghai Pudong Intentional Airport, Hangzhou Xiaoshan International Airport or Wenzhou Longwan International Airport, then come to Lishui railway station through high speed train about 3 hours, 1 hour and 0.5 hour respectively, then we will pick you up at the railway station, hotel booking service is available.
