Frequently Asked Questions - Internal Doors

Q1: How do I measure a doorway opening for steel doors?
A1: Measuring a doorway for steel doors can be tricky, as construction or renovation work often leaves openings that are not perfectly rectangular. Some doorways may be skewed, with corners forming trapezoidal or diamond shapes instead of right angles. To ensure accurate dimensions for manufacturing, follow these steps:

Measure the width at three points: the bottom, mid-height, and top.
Measure the height at three points: the left side, right side, and the middle.
If possible, measure the diagonals to check for irregularities. While not mandatory, this can help confirm the overall shape.

Taking these six measurements ensures that the steel door and frame will fit perfectly, even if the opening has irregularities.

Q2: When should loft-style steel doors be installed?
A2: Loft-style doors or partition walls should be installed as the final step in your project. Complete all flooring, wall finishing, and wallpapering first. This ensures that the steel doors are installed cleanly and fit seamlessly into the finished space.

Q3: Is it difficult to install loft-style steel doors?
A3: Installing loft-style steel doors is straightforward and requires only basic tools. Many of our customers install doors from the “Portamet Standard” range on their own. The door frames come pre-drilled for installation, allowing them to be securely fixed to the wall with rawlplugs. Once the frame is in place, the glass panel is simply hung on the hinges.

Q4: What are pre-hung internal doors?
A4: Pre-hung internal doors, also calleddoorsets, are doors pre-fitted into a frame. Hinges, latches, and locks are already installed, and the door is prepared for handle attachment. These doors are ideal for new builds or renovation projects where existing frames are not being reused.

Q5: Can I use an external door indoors?
A5: Using external timber doors inside a building is not recommended. External doors are made from timber with higher moisture content, which may warp or deform in the dry, heated environment of a home. Additionally, external doors are typically thicker and may not fit standard internal frames.

Q6: How long do steel doors last?
A6: With proper maintenance, steel doors can last20 years or more. They are highly resistant to weather, impact, and fire, making them a durable, long-term investment for residential and commercial use.

Q7: Will steel doors rust?
A7: Steel doors can rust if not properly maintained. Most steel doors are coated with protective paint to prevent rust, but damage like scratches or dents can expose the metal. Regular upkeep, such as repainting and cleaning, will protect your door from corrosion.

Q8: Are steel doors better than wood?
A8: Steel doors offer superior security, durability, and weather resistance compared to wooden doors. They are less prone to warping, rotting, or cracking, making them ideal for long-term use. However, wooden doors may be preferred in certain decorative or historical contexts for their classic aesthetic.

Q9: Why should I consider glazed internal doors?
A9: Glazed internal doors enhance natural light flow between rooms, creating a brighter, more open atmosphere. They also add a modern and elegant touch to your interior design, combining functionality with aesthetic appeal.
