Start with opening size and usage
Balcony doors, patio doors, office partitions, and large living-room openings have different loads. A bigger shutter needs stronger profiles, better rollers, correct glass selection, and careful handling during installation.
Tracks and rollers
The track should be straight, clean, and suitable for the shutter weight. Rollers should move smoothly without noise or jumping. For heavier glass, ask whether the roller rating matches the shutter size and whether replacement rollers will be available later.
Glass and safety
- Use safety glass for large doors and high-traffic openings.
- Consider laminated or toughened laminated glass where impact or fall risk is higher.
- Ask whether the frame can safely carry the selected glass weight.
Locks, drainage, and finish
Check handle grip, lock engagement, interlock alignment, bottom drainage, sill slope, powder-coating quality, and sealant detail. A good sliding door should close firmly, drain rainwater correctly, and feel stable during daily use.
