Note: If there would be no tooling available to press your heads in a single piece, we can dish and press crown and petals and prepare them, ready to be welded, or if you prefer to keep that value added in your hands: deliver them as rough parts with sufficient allowance for you to cut to size, bevel and assemble them at your shop or site.
On request, heads of all types can be fitted with round or oval flanged-in or flue-out openings for manholes.
