Square slot with column

Cold heading process is one of the new processes for pressure machining of less or no cutting
metal. It is a processing method that utilizes the plastic deformation of metal under the action of
external forces, and with the aid of molds, redistributes and transfers the volume of metal to form
the required parts or blanks. The cold heading process is most suitable for producing standard
fasteners such as bolts, screws, nuts, rivets, and pins.etc

A column with a square groove is a structural element that features a longitudinal (lengthwise) square-shaped channel or recess along its surface. This design can serve functional, aesthetic, or load-bearing purposes, depending on the application.

Key Features:

Shape & Structure:
- The column itself may be cylindrical, rectangular, or another cross-sectional shape.
- The square groove is a recessed channel cut into the column, running parallel to its length.
- The groove may be centered, offset, or repeated in a pattern (e.g., multiple grooves for fluting).
- Square slot with column
Purpose & Applications:
- Aesthetic Design: Adds visual interest, often seen in architectural columns (e.g., decorative fluting in classical pillars).
- Functional Use: Provides space for wiring, piping, or reinforcement bars in construction.
- Weight Reduction: Grooves can reduce material usage while maintaining structural integrity.
- Assembly & Alignment: Helps in fitting adjoining components (e.g., sliding panels or joining beams).
Materials:
- Concrete: Used in construction for reinforced columns.
- Metal (Steel/Aluminum): Common in industrial and mechanical applications.
- Wood: Found in decorative or furniture design.
- Composite Materials: For lightweight, high-strength needs.
Manufacturing Methods:
- Machining: For metal or plastic columns (CNC milling, lathing).
- Molding/Casting: For concrete, polymer, or metal columns.
- Extrusion: Common for aluminum profiles with grooves.
- Carving/Routing: For wooden columns.

Examples of Use:

Architecture: Fluted columns in Greco-Roman designs.
Engineering: Square-grooved shafts for keyway fittings.
Furniture: Decorative table legs or support beams.
Industrial: Guide rails with grooves for machinery alignment.
