17-20cm Adjustable Aluminum Door Frame AK-170200

17-20cm Adjustable Aluminum Door Frame

Adjustable aluminum door frames designed for 17-20 cm wall thicknesses provide greater installation flexibility compared to traditional fixed frames. In buildings where wall thickness varies or plaster and finishing layers differ between projects, the adjustable frame allows a single model to cover multiple size ranges efficiently.

The goal of this system is to shorten installation time while achieving a seamless line at the frame-to-wall junction without gaps, openings, or aesthetic flaws. This is especially beneficial on busy construction sites where it helps minimize measurement errors.

How Does the Adjustable Frame System Work?

The adjustable (telescopic) frame consists of two overlapping parts that slide to fit the wall thickness:

• Frame sections slide forward or backward to adjust size
• The joint between frame and wall is covered for a clean appearance
• Fine adjustments can be made during installation

This design offers significant advantages for common interior wall thicknesses between 17 cm and 20 cm.

Technical Features and Material Benefits

The aluminum frame stands out for its durability and stability:

• Corrosion resistance: Ideal for humid environments
• Shape stability: Reduced risk of warping or twisting over time
• Surface durability: Strong resistance against impacts and abrasion
• Operational compatibility: Stable functioning with door leaf, hinges, and lock alignment

Compared to wooden frames, aluminum frames offer superior resistance to swelling, bubbling, and moisture damage.

Typical Applications

The 17-20 cm adjustable aluminum door frame is commonly used in:

• Residential interior doors
• Office and commercial partitions
• Schools and educational facilities
• Hospitals and clinics with high foot traffic (if door leaf is compatible)
• Hotel room entrances and service doors
• Common area doors in residential complexes

Installation Guidelines

The most critical aspect during installation is ensuring the frame is perfectly level and that the door leaf clearance is maintained correctly.

Checklist for Installation

• Is the wall thickness within the 17-20 cm range?
• Does the frame opening match the door leaf dimensions?
• Have level and plumb checks been performed?
• Are hinge lines and lock strike plates properly aligned?
• Are door clearances standard after frame installation?

Why Choose a 17-20 cm Adjustable Frame?

The main reason to select an adjustable frame in this size range is the frequent on-site wall thickness variations.

Examples include:

• Differences in plaster thickness
• Transitions in tile or cladding layers
• Additional wall layers after renovations

In such cases, fixed frames may not fit perfectly, whereas adjustable frames adapt quickly on site.

This product type is a technical solution designed to meet the needs for precise sizing and material durability in interior door applications. Adjustable aluminum frame systems are engineered to address common wall tolerance challenges encountered during installation. When selected according to the size range, they ensure smooth closure at the frame-to-wall junction, long-term stable operation, and reduced installation time.
