The famous Chinese prefabricated warehouse

The development of China's construction steel will on a new level. Efficient welding process and new applications of welding, cutting equipment. Such as double-sided molding liner opposite monofilament various methods and multi-wire submerged arc welding, gantry-beam rapid bilateral double wire welding production lines, all kinds of CNC flame cutting machines and laser machines for steel production and production efficiency high-quality products to create a good condition.
