All wooden staircase parts are produced from the highest quality wood panels (A/B class). Factory ensures that all wood panels are delivered in accordance with strict requirements for wood humidity to reduce the risk of cracking. Each type of wood panel can be made in solid or finger joint (FJ) way.
What is the difference between solid and FJ? Solid hardwood planks are created from a single, thick piece of solid wood. A finger joint, also known as a comb joint, is a woodworking joint made by cutting a set of complementary, interlocking profiles in two pieces of wood, which are then glued. The greatest advantage of solid wood is that the wood is the same all the way through, so repairs are relatively easy. The two most important advantages of finger jointed lumber are straightness and dimensional stability.
