Sectional Flight
Falcon Industries is a premier manufacturer of sectional flighting, along with helicoid, ribbon, and shaftless flight styles. Our sectional flighting is formed using a wide range of press sizes and styles, giving us the manufacturing flexibility to produce a complete range of diameters, thicknesses, and mounting configurations.
An Overview of Sectional Flights
Sectional flights are individual turns, wraps, or segments of wraps formed into a helix. The cross-section of the sectional auger flight is the same uniform thickness from the OD to the ID.
Sectional flighting is often used when the height, or web, of the flight, is larger than what can be produced with a flat bar in helicoid flight. Sectional flighting can be manufactured in a wide range of sizes. The formability of the base material generally limits the flight dimensions, but Falcon can work with you to overcome these limitations by using multi-piece sections and material options.
Falcon can provide sectional flight with integral spokes, cut and folds, sawtooth edges, and bolt holes for mounting teeth and shoes. Sectional flighting is one of our specialties; we have a breadth of press sizes and styles that allow us to offer a complete range of diameters and thicknesses. Large quantity price breaks are available. Our sectional flighting is perfect to use in cases where extreme auger wear can occur, and individual flights require replacement.
Falcon produces sectional flights in diameters as small as 1-1/2” up to 148” and thicknesses up through 1-1/2”. We can program our plasma machines to cut flight blanks with a precut tapered OD, tapered ID, or both diameters tapered and make a flight that fits a square center shaft.
Materials & Grades
Sectional flighting can be formed from a wide range of base materials to match your application’s wear, corrosion, and load requirements, including carbon steel, abrasion-resistant (AR) steel, stainless steel, and specialty alloys such as A514 Gr. B (T-1). Our team can help you identify material and thickness options based on the material you’re conveying and your application requirements.
Sectional Flighting vs. Helicoid Flighting
Sectional flighting is built from individual segments that are typically welded into a continuous helix length, holding a uniform thickness from the outer diameter to the inner diameter. This design is well suited for applications where the flight height (web) is larger than what can be formed from a flat bar, or when individual sections need to be replaced due to wear without rebuilding the whole flight. Helicoid flighting, by contrast, is rolled continuously from a single flat bar, which typically makes it a more economical option for consistent web heights and long, continuous runs. Falcon manufactures both — see our Helicoid Flighting page to compare.

Frequently Asked Questions
Common questions about sectional flighting specs, materials, and customization.
Q1. What is sectional flighting?
Sectional flighting is auger flighting made from individual segments, or wraps, that are formed and joined into a continuous helix. Unlike helicoid flighting, which is rolled from a single flat bar, each sectional segment holds a uniform thickness from the outer diameter to the inner diameter, which makes it well suited to larger or heavier-web flight profiles.
Q2. How is sectional flighting different from helicoid flighting?
Sectional flighting is used when the flight height (web) is larger than what can be formed from a flat bar in helicoid flighting, or when individual sections need to be replaced due to wear without rebuilding the entire flight. Helicoid flighting is typically more economical for continuous runs at consistent web heights.
Q3. What diameters and thicknesses does Falcon produce?
Falcon manufactures sectional flighting from 1-1/2″ up to 148″ in diameter, in thicknesses up through 1-1/2″. Diameter and thickness are ultimately limited by the formability of the base material; for larger sizes, we can work with you on multi-piece sections and material selection. We can also sandwich flights to make a thicker flight if required.
Q4. Can sectional flighting be customized for a specific shaft or mounting need?
Yes. We can program our plasma equipment to cut flight blanks with a tapered OD, tapered ID, or both, and can produce custom configuration flighting. We also offer integral spokes, cut and folds, sawtooth edges, and bolt holes for mounting teeth and shoes.
