Wood flooring has silently invaded into our most intimate place – home. When it comes to wood flooring selection, customers tend to put their emphasis on texture and the origin of wood plus the process of treatment are often neglected. Thus, Keding Enterprises has devoted to launch engineered hand scraped wood flooring and at the same time provide transparent purchase information, enabling our customers to enjoy a secure and satisfactory product.

Manufacturing Process
 
 
KD Wood flooring
 
Commercially available composite wood flooring
Size


  8:3:2 made of golden ratio, creating
  unbelievable visual esthetics.

 

  Either too small to be great, or too large
  to reach delicacy.
Deformation


  Take the Prestressed Concrete” measure,
  hard to deform.

 

  Without any treatments, easy to deform.
Surface Materials Treatment


  Soaked in the water of 90℃~95℃in a
  vacuum for 7 days to create clear and
  distinguished wood grains.

 

  Made of poor quality materials, knots are
  perceivable but the wood grains are
  unperceivable.
Texture


  Designed by artistic sculptors, exceptional
  feel of  hand-scraped flooring.

 

  Lousy and flat, the feel is the  same as
  plastic flooring.
