Pressbrake Bending AKA Cold Forming

Cold Forming: The Precision Art of Pressbrake Bending and Folding

Cold Forming, commonly known as Pressbrake Bending or Folding, is a specialised technique for shaping metal without the need for heating. This process involves the use of top and bottom tooling to press the metal into specific shapes and dimensions tailored to each customer’s unique requirements. At Mascot Steel, we operate state-of-the-art, fully CNC-controlled brake presses:

  • 200-tonne x 3.6-meter press: Ideal for large-scale, heavy-duty projects.
  • 135-tonne 8 Axis CNC Press
  • 60-tonne x 2-meter press: Suited for smaller, more intricate work.
These machines are versatile enough to cold form a wide array of shapes, including steel channels, zeds, and angles. We work with various material grades, such as stainless steel, hot rolled steel, and Aluminium. For more specific requirements, feel free to contact us at sales@mascotsteel.com.au.

Cold Formed Equal Angle Section Manufactured From Sheared Plate or Strip Cut to Size on Our CNC Guillotine to a Customer’s Specific Dimensions.

Zed Sections

Customised Cold-Formed Zed Sections: Precision Engineering for Your Specific Needs

Cold-formed Zed sections are crafted from folded, sheared plates or strips and are customised to meet the unique dimensions of each individual project. These sections offer a high degree of flexibility in design and application.

Additional Features for Versatility

  • Holes or Slots: Customisations such as holes or slots can be added as per your project requirements.

Design Guidelines

  • Base vs Leg Dimensions: The base dimensions of the Zed section must exceed the dimensions of the leg for structural integrity.

Precision in Every Bend

  • Internal Radius: The internal radius of the bend is calculated as 1.6 times the thickness of the material. For example, a 5mm thick angle will feature an 8mm internal bend radius.

Choose our cold-formed Zed sections for a tailored, precise, and versatile solution for your project’s structural needs.

Zed sections are used for secondary connections in all parts of the building envelope.

Cold Formed Channels

Also known as c sections, u channels or pressed channels

The ratio of the leg to the base of the channel section depends on the thickness of the material being pressed. As a rule:

  • Internal radius is 1.6 x thickness
  • Internal radius is 1.6 x thickness

Cold Forming Tolerances

Can you fold different shapes?

Absolutely! Beyond our standard offerings, we can fold a variety of shapes, including trays, upstands, and lips. For specific requests, please send a drawing of your desired shape to sales@mascotsteel.com.au.

Finishing Options

  • Parts are available in their natural self-colour or mill finish, which means they come without any additional treatments.
  • Cold-formed carbon steel components can be enhanced with protective coatings, including galvanising, wet paint or polyester powder coating.
  • For stainless parts, we offer finishes like pickling & passivation and polishing.
