Door Styles Explained

1. Outswing/Walk-In Door:

  • Accessibility: They provide easy entry and exit, making them suitable for various applications.
  • Weather Resistance: When properly sealed, they can offer good weather resistance.


  • Space Requirements: They require adequate exterior space for the door to swing open.

2. Entry Door:

  • Durability: They are built to withstand frequent use and harsh weather conditions.
  • Security: Roll-up doors can be reinforced for added security.

5. Double Shed Door:

Definition: Double shed doors consist of two single doors that open separately. They provide a wider entry point, making them suitable for larger portable buildings.
