A TR4 TR5 machine refers to a type of cold roll forming machine used to manufacture metal roofing sheets, specifically creating TR4 and TR5 profiles (Trapezoidal Roof profile 4 and 5), which are popular for industrial and residential buildings due to their strength and aesthetic appeal, often forming double layers (TR4/TR5) for efficiency in a single machine. These machines take flat steel coils, feed them through a series of rollers to shape them into the desired corrugated or trapezoidal pattern, and then automatically cut them to length, all controlled by PLC systems.

1. A machine doesn't just provide a few photos to prove what they can produce
2. A machine should have a complete production and assembly system photos and videos. When choosing a company with a factory, it is necessary to ensure that the company has a complete after-sales service system.
Our company's engineers have studied in well-known European cold bending companies and have great advantages in machine design and R&D and manufacturing.
Generally speaking, the machine takes about 40 days to complete, if you need a machine urgently, we can make it urgently, because I have a large number of spare parts.
Because we insist that every factory should put quality first, we make the machines more automated, more reliable and accurate, and have a longer service life.
The equipment can be used for nearly 20 years, and we provide lifetime after-sales service.
Product quality is the ultimate, the biggest after-sales service is service, 26 years of production experience, to be a service company that you have the strength to guarantee
1. Give me the dimension drawing and thickness, it is very important.
2. If you have requirements for production speed, power, voltage and brand, please explain in advance.
3. If you don't have your own outline drawing, we can recommend some models according to your local market standard.
At here, it’s all about giving the clients the best quality products.
