System Overview
A-Type Keel Clip-in System
Panels are clipped into A-type keels on all four sides, creating a seamless monolithic ceiling surface with no visible grid lines or fasteners.
Concealed A-type keel clip-in aluminum ceiling system for seamless, monolithic ceiling surfaces. Panels snap directly into A-type keels on all four edges - no visible fasteners, clean modern finish.

| Grid System | A-type keel concealed clip-in - no visible grid lines |
| Perforation | Available: 1.8mm, 2.0mm, 2.5mm, 3.0mm round hole; open area 15-30% |
| Acoustic Performance | NRC up to 0.75 with perforation + acoustic fleece backing |
| Fire Rating | Class A (non-combustible) per ASTM E84, EN 13501-1 |
| Installation | Clip-in: press panel edges into A-type keel; removable by flexing one edge |
Perforated clip-in panels with acoustic fleece backing improve sound absorption for offices, hospitals, classrooms and public spaces.
Clip-in panels can be perforated with various hole patterns. Standard round holes in staggered arrangement. Custom patterns and micro-perforation available for special acoustic and aesthetic requirements.
| Hole Diameter | Pattern | Open Area |
|---|---|---|
| 1.8mm | Staggered round | ~15% |
| 2.0mm | Staggered round | ~18% |
| 2.5mm | Staggered round | ~23% |
| 3.0mm | Staggered round | ~28% |
A black acoustic fleece pad is heat-bonded to the back of each perforated panel. Sound waves passing through perforation holes are absorbed by the fleece, improving the Noise Reduction Coefficient (NRC).
| Configuration | NRC Rating | Application |
|---|---|---|
| 600x600 / 0.8mm / 2.5mm perf + fleece | NRC 0.65-0.75 | Offices, classrooms |
| 600x1200 / 1.0mm / 2.0mm perf + fleece | NRC 0.60-0.70 | Corridors, public areas |
| 600x600 / 0.8mm / non-perforated | NRC 0.05-0.10 | Clean rooms, wet areas |
Ballesta clip-in ceiling systems deliver a premium seamless finish with reliable performance across commercial and public building projects.
A-type keel clip-in system creates a continuous ceiling surface with no visible grid lines or fasteners. Panels snap in flush for a premium, uninterrupted aesthetic.
Each panel can be individually removed by pressing a designated release point - the panel flexes slightly to disengage from the A-type keel. Targeted access without disturbing adjacent panels.
Perforated clip-in panels with acoustic fleece backing achieve NRC ratings up to 0.75, controlling reverberation and ambient noise in offices, classrooms and public spaces.
All aluminum clip-in panels are non-combustible with Class A fire rating per ASTM E84 and EN 13501-1. No toxic fumes emitted in fire conditions - safe for all occupancy types.
Available in 300x300mm, 600x600mm, 300x600mm, and 600x1200mm. Multiple thickness options (0.5mm to 1.0mm) suit different span requirements and load capacities.
Powder coating in any RAL or Pantone color, anodized finishes (natural, champagne, bronze, black), and wood-grain transfer printing. Custom colors for brand-matching projects.
Complete system components for the clip-in ceiling installation.
Standard installation sequence for the clip-in ceiling system.
Secure the C-channel to the structural ceiling using rods and hangers at designed spacing.
Connect hangers from the C-channel to support the A-type keel framework.
Snap the A-type keel main runners and cross tees into position to form the grid framework.
Press each panel edge into the A-type keel on all four sides simultaneously for a flush, seamless surface.
Ballesta clip-in ceiling systems are specified across a wide range of commercial and public environments.

Clip-in panels snap into A-type keels on all four edges, creating a seamless monolithic surface with no visible grid lines. Lay-in panels rest on T-bar grid flanges where the grid remains partially visible. Clip-in delivers a more premium, uninterrupted aesthetic.
Standard sizes include 300x300mm, 600x600mm, 300x600mm, and 600x1200mm. Custom sizes are available for special project requirements. Panel thickness ranges from 0.5mm to 1.0mm depending on span and loading conditions.
Yes. Perforated clip-in panels with acoustic fleece backing achieve NRC ratings up to 0.75. Standard perforation patterns include 1.8mm, 2.0mm, 2.5mm, and 3.0mm round holes in various open-area configurations.
Clip-in panels can be individually removed by pressing a designated release point on one edge. The panel flexes slightly to disengage from the A-type keel. This allows targeted access to overhead services without disturbing adjacent panels.
Powder coating in any RAL or Pantone color, anodized aluminum (natural, champagne, bronze, black), and wood-grain transfer printing. Standard stock colors include RAL 9003 (Signal White) and RAL 9006 (White Aluminium).
All Ballesta clip-in aluminum panels achieve Class A fire rating per ASTM E84 and EN 13501-1. They are non-combustible and emit no toxic fumes in fire conditions, suitable for all occupancy types including high-rise buildings.
