Stone colour shades are a close representation of our stone colour range. Stone samples are available by request if required.

The various designs and products shown on the product list are predominately decorative, with the exception of Quoins, Ashlar Blocks and String/Plinth Courses, which are load bearing in compression only. Any galvanised 'handling' reinforcement steel incorporated in the various components, is as required and in accordance with the relevant British Standard.

Any third party using wholly or in part the detailed designs contained herein must ensure that those designs satisfy the necessary standards and building design requirements of the application concerned. Information and advice is given in good faith as is, to the best of our knowledge, accurate and true. (Being offered without guarantee.)

The Customer must, therefore, satisfy himself of the suitability of any of the products prior to them being used as Ilam Stone will not accept any responsibility for errors and omissions. Whilst detailed drawings may be provided prior to the commencement of manufacture, these are representations of the 'Cast Stone' and should, in all cases, be approved by the Architect and/or Structural Engineer. Balustrade systems are not designed to resist barrier loading as required in the Building regulations and in BS 6180. The advice of a Structural Engineer should be obtained if barrier loading is to be resisted by the Balustrade system. In all cases advice should be sought from the appropriate specialist.
