求翻译：该材质与结构钢相似，但除强度外，要求有更高的伸长率值等，以保证具有良好的加工成形性能，对表面质量及尺寸公差要求严格。是什么意思？

The material and structural steel, but in addition to strength, requiring a higher elongation values ​​to ensure that with good forming properties, surface quality and dimensional tolerances demanding.

The quality and structural steel similar to, but in addition to strength, with a higher Elongation values, and so on, in order to guarantee a good performance, forming the processing of the surface quality and size tolerances.

This material quality is similar with the structural steel, but besides the intensity, the request has the higher elongation ratio value and so on, guaranteed has the good processing forming performance, is strict to the surface quality and the size common difference request.

Similar to the material and structural steel, but apart from strength, requires a higher degree of elongation values, and so on, to ensure the good forming performance, strict demands on surface quality and dimensional tolerances.
