Selecting utility castings can be surprisingly challenging.

In order to do so, buyers, specifiers, stockists and contractors have to navigate the potential minefield that is presented by the variety of products, specifications and third-party standards.

As with many other construction products, unit price is obviously an important factor. But more important are quality, suitability and total cost of ownership (TCO).
