Alloywood plastic lumber is a new-type environmental protection material for construction. It is high density polyethylene that is melted and extruded into a wood appearance and shape.

Alloywood is engineered for durability and performance in outdoor or backyard environments. It will stand up to the sun's Uv rays and not splinter, check, or crack like wood. Since the wood fibers are encapsulated in plastic. Alloywood will not absorb moisture and even without costly annual sealing, it will not swell, rot, or twist like wood.
