Meanwhile, if you have any advice or complaints, also welcome to feed back to our after sales department, and we are trying to give better service to you.

Cold rolled coil products material S355ML have accurate size and uniform thickness, and the thickness difference of coil is generally less than 0.01-0.03mm or less, which can fully meet the requirements of high precision tolerance. The surface quality of cold rolled products material S355ML is superior, and there are no defects such as pockmarks, pressing iron oxide scale and so on, which often appear in hot rolled coils. According to the requirements of users, coils material S355ML with different surface roughness can be produced (glossy surface or matte surface, etc.).

material S355ML, Grade P295GH chemical composition under EN10028-2:2003 is displayed as follows. Chemical composition (C: 0.08 to 0.20; Cr: ≤0.30; Si: ≤0.40; Cu: ≤0.30;Mn: 0.90 to 1.50; Mo: ≤0.08;P: ≤0.025; Nb: ≤0.020;S: ≤0.015; Ni: ≤0.30;Al: ≤0.020; Ti: 0.03; N: ≤0.012; Vi: ≤0.02). The yield Strength MPa (min) of P295GH steel plate with thickness less than 16mm is 295MPa, and the tensile strength is 460-580MPa.

Our company will accept the product quality objection registration record, pass it to the material S355ML production unit and relevant departments, and timely coordinate the supervision of product material S355ML quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
