S690QL yield strength for engineering steel

We have a lot of advantages for S690QL yield strength steel plate processing. First, we have huge steel plate stock. That not only saves material preparation time, but also saves much transportation cost. Second, we have professional technical team, who can design drawing according to client requirements quickly. Or if clients have drawing, we can communicate and make it clear soon. Third, we have built special steel processing center. The professional and experienced work will make you more satisfied and at ease.

In recent years, after the completion of large-scale, high-speed and automation of steel rolling technology and equipment in the world, the rapid development of S690QL yield strength high-precision rolling technology with the goal of improving product quality, expanding varieties, saving energy and reducing consumption, and increasing benefits. For example, in 2013, Bebon Iron and Steel's 4300 mm rolling mill, 5000 mm rolling mill and 3500 mm furnace coil rolling mill introduced foreign technology to further upgrade the company's S690QL yield strength technical equipment.
