Service definition
State whether the joint is a mounting interface or has pressure, sealing or code requirements; a cut plate is not automatically a rated flange.
Custom Stainless Steel Flat Flange Plates
Profile-cut stainless steel flange plates with a central opening and a customer-defined bolt circle. These pages describe custom flat interfaces; pressure-rated flange requirements must be specified and separately reviewed.

Flat Flange Plates: dimensions and quotation parameters.
The dimensions below help us review flat flange plates. State units and critical tolerances on the original drawing. The illustration explains the type of geometry; it does not define a standard size.
| Outside profile | Provide the outside diameter or custom perimeter. |
|---|---|
| Center opening | Dimension the opening and its concentricity requirement if critical. |
| Bolt circle | State bolt-circle diameter, hole count and starting angle. |
| Joint details | Identify the gasket contact region and mating component. |
| Material & quantity | Give the exact metal grade, standard, temper or condition, quantity per revision and planned repeat orders. |
| Units & tolerances | Use mm or inches consistently. Mark the dimensions that control fit and the inspection datum. |
Thickness range, minimum features, tolerances, finish availability and delivery date are reviewed for your actual part. No catalog dimension or blanket machining tolerance is implied.
What we review
before cutting.
Cut contours, hole function and the way the plate meets its mating parts.
Bolt indexing
Dimension the angular position of the first hole relative to a datum rather than giving only the hole count.
Material and finish
belong in the drawing.
Grade, environment and visible-face requirements are separate specification choices. Include them before quotation so the material and process route can be reviewed together.
Specify the grade
Stainless steel options include 304, 304L, 316, 316L, 430 and duplex 2205. Carbon steel, galvanized steel, aluminium, copper and brass can also be discussed for your drawing. State the exact grade and applicable material standard.
Read the grade selection reference for general material context. Availability, product form and suitability are confirmed for the project. Explore all six material families.
Define the finished surface
Identify a mill finish, brushed appearance or another specified finish; include the visible face, grain direction and any surface-roughness requirement.
Specify edge deburring, protective-film handling and packing if they affect the delivered part. Read the finish terminology guide.
Material options are reviewed against your drawing, grade, thickness and finishing needs. Stainless steel remains our core focus; sourcing and the manufacturing route are confirmed during quotation.
Inspect the features
that matter to your assembly.
Inspect the central opening, bolt-circle location and perimeter. Sealing surfaces or pressure-related requirements need a project-specific review.
Provide the inspection datum, critical dimensions and any requested records with the inquiry. A model preview supports communication; the approved engineering drawing remains the manufacturing reference.
Quality & material requirementsFlat Flange Plates:
common questions.
Are these standard pressure flanges?
They are made-to-drawing flat flange plates. If a standard, pressure class or sealing-face specification applies, provide the complete requirement for feasibility review.
What should I send for a quotation?
Send your flat flange plates drawing, grade, thickness or tube section, quantity, finish and critical dimensions. A clear PDF or image is accepted for review; a DXF supports flat cutting contours.
Can I request prototypes and production batches?
Include prototype quantity and expected repeat quantity in the inquiry. Batch size, process route and lead time are confirmed after the drawing and specification review.
