Abstract

A method and apparatus are provided for making a metal product with improved surface characteristics. The method provides for treating the metal product through a method comprising: heating the metal product; exposing the outer surface of the metal product to a controlled environment; and oxidising the outer surface of the metal product. The heating may take the metal product to an elevated temperature, the elevated temperature of the metal product being at least 725°C. The method further comprises a controlled environment around the metal product which is controlled with respect to the atmosphere around the metal product, and in particular the nitrogen and/or oxygen and/or hydrogen content thereof. The result is a more consistent surface for elongate metal products, having a more consistent colour to the surface, a more durable and hard wearing surface and/or a surface which is not prone to flaking.
