Recently, we developed a new customer in overseas. We knew each other by google searching.

And he is so happy to hear that our OTAI is the largest stockist in south of China.  Because of the cutting machines limitation, they can only order the 4140 alloy steel flat bar no wider than 600mm width. The price is better than he used to buy from local. It really is very good for him if they could develop a new supplier. But they need some time on the investigation. At this moment, it is impossible to have the business trip by visiting us from abroad to China because of the COVID-19.

Even the COVID-19 made the visiting plan delayed, but it will not stop and delay our new cooperation. So we suggest the customer to come to visit us by his good friend in China.And his friend came to our warehouse for the visiting and on-site investigation.

First

We checked our testing room for the Chemical Spectrometer, it is used for testing the chemical composition. And the Ultrasonic Tester for checking the inside quality of steel material. At last the hardness tester for testing the hardness.We have the toured around our warehouse for the 4140 steel plates and 4140 alloy steel flat bar stock and some round bars stock.

At the end

The customer’s friend is so surprised to see our different machines. That is CNC flame cutting machine, huge vertical saw cutting and the band saw cutting. Besides, we even have the single and double milled machines for milling bright surface! He really is very impressive on our one stop solution service.

He considered that we are the large stockist with the 21years experience on this steel field. And we have the qualified quality by ISO cert and accredited by Thyssenkrupp. So in next day, the abroad customer placed the 4140 alloy steel flat bar order to us immediately. We are really much appreciated for these new customers’ trust on us, the best we can do and give back to you is our guaranteed quality and service.
