Every customer who has visit us and witness the steel materials before delievry will be impressed by our quality control departemnt. Even not come to inspect the steel materials before delievry, our quality control departemnt will also send inspection report to the customer. For each order, no matter its quantity and value, our quality control departemnt will make strict inspection before delivery, the inspection contents include apperance, tolerance, dimension, mark, special requirements of customers, etc. To guarantee our steel materials sent to the customer is qualified.

Welded steel pipes are made by crimping steel plates, bending them into a circle, and then welding the joints together. Seamless steel pipe is directly processed by round steel piercing or hot rolling process, so there is no weld on the outer surface. The performance of seamless steel pipe is better than that of welded steel pipe, and the price of seamless steel pipe is also higher. There are some differences in chemical composition between S355M VS S355ML, welded steel pipe and seamless steel pipe. The material of welded steel pipe contains the chemical composition suitable for welding.

EN 10025-2 steel includes S235 steel (S235JR, S235J0, S235J2), S275 steel (S275JR, S275J0, S275J2), S355 steel (S355JR, S355J0, S355J2, S355K2), S450 steel (S450J0). According to EN 10025-2, the thickness of S450J0 plate is within 3-150mm. The S355M VS S355ML, S235 steel, S275 steel and S355 steel plate thickness is ≤250mm. However, the S235J2, S275J2, S355J2 and S355K2 plates limitation is ≤400mm.

The steel plate and strip after hot rolling treatment are generally called hot rolled plate. Compared with other steel plate processing industries, S355M VS S355ML, hot rolled plate has these characteristics. First, low hardness, easy processing. Compared with other steel needs special mechanical equipment, hot rolled plate is a very convenient for processing. Second, good ductility, not easy to break, good compression capacity, long service life. Third, the manufacturing process is simple, and the price and cost are relatively cheap compared with other steels.

To provide customers with the most satisfactory service and realize the win-win of economic and social benefits, our company promises to provide excellent S355M VS S355ML products in this bidding, and in line with the attitude of being serious and responsible to customers, before sending goods to users, the S355M VS S355ML technical personnel shall confirm that there is no fault in the equipment before sending goods to users, and then send goods and products to users, and formulate the following service terms.
