Real red-corrosion finish

(Chemical coloring treatment by the accelerant + clear painting)

We achieve to make this red-corrosion by using accelerant in stead of natural red-corrosion which is appeared by the aged deterioration. The pattern textured by many colors will appear at 3D portion in red-corrosion because this treatment is done by hand. So that the different design on each surface is appeared.

Explanation of finish

The red color and partially black color corrosions on the steel products will be generated by wind and rain for many years. Because of this unique imagination textured by colors, we are providing this unique product of which is produced the chemical coloring by the red-corrosion accelerant in short period. Each product has been obtained different pattern because our specialists are making there products as same as patina by the hand-made.
In addition our process is dry method which is painting the special chemical by rolloer or brush without dipping and the bubbles and rust on the back side of material will also be appeared. The size of products is referring to the following column “Notes and others”.
We can produce two types of colors which are red and black color tones. But please note that the pattern on each product will be totally different appearance. So kindly make an imagination by color on the sample and design based on your imagination.
And the red-corrosion has the loose corrosion and adhesive corrosion as which is natural chemical film (basic salt) on a copper alloys. We have to remove this loose corrosion as much as possible and adjusting the color at this portion, thereafter, the clear coating for protection is provided. The clear coating is urethane series and the luster is basically supplied the mat tone of about 30 percent gloss.

Notes and others
  • Our treatment on the surface is provided based on after formed, therefore, the bending, shearing and making holes process shall be done before red-corrosion treatment in order to avoid peeling the red-corrosion and clear coating.
  • The products size will be 1,500mm(W)×5,500mm(L). And the weight is max. 100kg. If it is more than the above size or weigh, please freely contact us.
  • As time passed, the rust on the iron is proceeding. The red-corrosion will also be changing as time passed. Please understand this feature and decide this product.
  • Our treatment works are provided in our factory, so we do not accept the treatment works at job site.
  • The touch up works will be carried out using the similar color.
  • Please don’t use the benzine, thinner, scotch and etc for the maintenance on the surface because the cause of discoloring. Please carry out the periodic cleaning by soaking a soft cloth with neutral detergent, thereafter it wipes the wet surface with dry cloth.
