Now most people who decorate the floor like to lay tiles in the living room and wood floors in the bedroom. However, the wooden floor will expand and contract due to heat, so many people may leave some gaps between the boards. We recommend that you use aluminum transition strips for flooring to decorate the gaps in these expansion and contraction spaces. Aluminum alloy material is light and strong, not deformed by external force, easy to install, and the price is much cheaper than stainless steel and copper.
