This formulation is of great harm to the quality supervision and fair market competition of wood fire doors. Can be sure that the wood is not flame-retardant treatment, and do not use fireproof paint or non-combustible materials for protection, fire-resistant doors will certainly not reach the fire-proof door requirements.
