Hollow Metal Frames: Welded Versus Knock Down

When it comes to choosing a commercial door frame, you'll likely come across two primary options: welded frames and knock-down frames. Understanding the differences between these two types of frames can help you make an informed decision for your specific project needs. 

Welded Frames:

Welded frames are typically made from steel and are fabricated by welding the corners of the frame together followed by a sanding of the weld seams. They are considered to be one of the most durable and long-lasting frame options on the market. Welded frames are also preferred in environments where high security and stability are required, such as government buildings, hospitals, and schools.

Advantages of Welded Frames:

  • High durability and long-lasting strength.
  • More secure due to fewer moving parts.
  • Little to no assembly required.
  • Can be custom made to fit any size or shape.

Disadvantages of Welded Frames:

  • More expensive than knock-down frames.
  • Can be challenging to transport and maneuver.
  • Difficult to replace or repair if damaged.

Knock-Down Frames:

Knock-down frames are also made from steel, but they are designed to be assembled on-site rather than being pre-welded together. They come in a 3-piece kit form and require assembly by the installer. Knock-down frames are commonly used in the interiors of new construction projects or tenant improvements, as they are easier to transport and maneuver.

Advantages of Knock-Down Frames:

  • More affordable than welded frames.
  • Easier to transport and maneuver due to the smaller size.
  • Replacement and repair are easier as only damaged parts can be replaced.
  • Ideal for large-scale projects due to the ability to transport in bulk.

Disadvantages of Knock-Down Frames:

  • Assembly is required, which can add time and labor costs to the installation process.
  • Can be less secure than welded frames due to more moving parts.
  • May not be suitable for high-security environments.

Choosing between welded frames and knock-down frames ultimately comes down to your specific project needs and budget. Welded frames are more durable and secure, but they come at a higher cost. Knock-down frames, on the other hand, are more affordable and easier to transport, but require assembly and may not be suitable for high-security environments. By understanding the differences between these two options, you can make an informed decision that best fits your project needs.
