Ductile iron, stainless steel trim

What approval do these carry?

It depends on the item and on the market. Send the standard your authority works to and we will confirm which listing the item carries and, where it has none, what the alternative is.

Can you supply a different size or finish?

Yes, if the pattern allows it. Send the size, the finish and the quantity and we will confirm whether it is a standard item or needs a new pattern.
