All of our materials are sold as semi-finished products. This means that thickness and diameters quoted are generally oversize to allow for subsequent machining. Similarly, standard sheet sizes and diameter lengths quoted are for indication purposes only and are normally the minimum manufactured size you can expect. Manufacturing tolerances of individual materials can normally be found on each product page, or alternatively contact the sales office for confirmation BEFORE you place your order. Returns due to material supplied within normal manufacturing tolerances will not be accepted under any circumstances.
Wherever possible we supply branded Tufnol®, but we reserve the right to supply material certified and manufacture to the same British Standard where necessary (eg due to stock availability)
