Pre-painted steel coils

The prepainted steel sheet for construction is an attractivesubstitute for wood and other materials, owing to its advantages,including fast color, good durability performance, chalkingresistance, etc.It minimizes the maintenance cost. At the sametime, various colors, surface structures and coatings providesuch products with great flexibility and option.

The name : Pre-painted steel coils

Model :

The prepainted steel sheet for construction is an attractivesubstitute for wood and other materials, owing to its advantages,including fast color, good durability performance, chalkingresistance, etc.It minimizes the maintenance cost. At the sametime, various colors, surface structures and coatings providesuch products with great flexibility and option.In China, more than 90% color coated sheets are applied inconstruction, and Baosteels prepainted steel sheets are alsowidely used in such field.Baosteel’s prepainted steel sheets satisfy the large-scale halls’rigorous requirements in construction in material color, shape,quality, property, etc. They have been recognized by manylandmark buildings in China, covering hall centers, sports halls,aviation knobs, cultural facilities, etc. After 15 years’ continuousresearch and improvement, Baosteel has been not only widelyused but also been commonly recognized in auto, non-ferrousmetal, power industry, coal mining, light industry, medicine,foodstuff, etc. Baosteel’s construction steel has alreadysubstituted traditional building materials with its safety, durability
