What Is the 18mm Series Aluminum Frame System?

The 18mm Series is a specialized sliding door track and frame system designed specifically for 18mm-thick door panels. It's a complete solution that includes:

Track Components:

• Top track (ceiling-mounted or support bar-mounted)

• Bottom track (floor-mounted with adjustable wheels)

• Precision ball-bearing rollers for smooth, silent operation

• Adjustable guides (prevent wobbling and side-to-side movement)

Frame Components:

• Top frame piece (aluminum profile, fitted to track)

• Bottom frame piece (aluminum profile, fitted to track)

• Side guide profiles (ensure perfectly vertical alignment)

• Corner connectors and fasteners (all stainless steel)

Hardware Components:

• High-precision ball-bearing rollers (rated for 100,000+ cycles)

• Soft-close dampers (optional, smooth closing)

• Emergency stop system (prevents accidental slamming)

• Adjustable alignment hardware (fine-tune perfect fit)

Why "18mm" Matters

The 18mm measurement refers to the thickness of door panels the system accommodates:

• 18mm glass panels: Standard tempered glass (6mm) + aluminum frame (12mm) = 18mm total

• 18mm composite panels: Plywood or MDF + aluminum edge profiles = 18mm total

• Precision fit: Designed to create seamless, gap-free door closure

• Professional appearance: No visible gaps, perfect alignment, clean aesthetics

Panels of different thicknesses require different track systems. Choose 18mm system for 18mm doors. For 16mm or 20mm doors, different systems are available.

How Does It Work?

The 18mm system operates via precision-engineered ball-bearing rollers that glide smoothly along aluminum tracks:

1. Top Track: Fixed to ceiling or support structure, acts as primary guide

2. Ball-Bearing Wheels: Suspended from top track, carry door weight

3. Bottom Track: Guides and stabilizes door movement, prevents side-to-side wobble

4. Soft-Close (Optional): Hydraulic dampers provide smooth, controlled closing

5. Adjustment Hardware: Fine-tune height, depth, and angle for perfect alignment

Result: Smooth, silent, gap-free door operation that maintains perfect alignment year after year.
