Custom Castings.
For utilities, engineers, contractors and distributors who need a casting made to their own standard.
✓ Made to your drawing ✓ Local patterns and cast lettering
✓ Approval before production
What to send your regional team
- Your drawing or standard detail
- The casting type and size
- The lettering or mark to cast in
- The quantity and the job location
Your pattern, your lettering.
Castings vary from city to city, often down to the pattern and the words cast on the lid. SIGMA takes custom orders made to the customer's specification, including a local pattern, a city's name or your own marking cast in.
It starts with your drawing or standard detail. SIGMA engineering develops the drawing, and a sample and a dimensional report come back for approval before production.
Two ways to start.
Many local patterns are already on SIGMA's regional price sheets. If yours is not, your regional team can quote it as a custom casting. The sheets are all dated March 15, 2024. Not sure which region covers the job? Find your regional team.
Check the sheets first
Many city and utility patterns are already on the regional price sheets. Look for yours before you ask for a new casting.

Every casting carries its heat number.
The heat number traces a casting to the foundry, the date and the production batch. SIGMA has inspection procedures for each castings product line, at the foundry and again at SIGMA.
