Pouchard offers a permanent stock of 15,000 tons of carbon steel tube and associated product, and 5,000 references. Sizes range from 7mm to 700mm in diameter of round, square or rectangular tube and chromed plated bars. These are typically used by the mechanical, hydraulic, heat, construction and piping industries, and are immediately available from stock. Drawing and surface treatments have advanced significantly over the years, and cold drawing has become a sophisticated process. Tubes of varying sizes and shapes can now be produced to precise specifications with a wide range of mechanical properties, tolerances and surfaces. With a choice of finishing options (eg heat treatment, surface treatment, cut-to- length, hammering out, and mouth openings, etc) the final product can be produced. The company has developed a process for cutting, machining and boring tubes,
