Why This Series

Engineered for Every Detail

Every aspect of the 50SS Series is designed to deliver reliable performance, safety, and long-term value.

±0.2mm Precision

Wall thickness tolerance held at ±0.2mm across every run — tighter than industry standard. Guarantees perfect hardware fit without re-machining by fabricators.

???

Weatherproof Sealing

Multi-point EPDM gasket channels integrated into the profile design. Keeps monsoon rain, wind, and dust firmly outside — even under sustained pressure.

???

Thermal Comfort

The 2-chamber cross-section traps still air as an insulating barrier, significantly reducing heat transfer compared to single-chamber or aluminium alternatives.

Sound Dampening

Dense uPVC compound and multi-gasket design reduce external noise penetration — ideal for homes near busy roads, markets, or railways.

100% Lead-Free

Formulated with calcium-zinc stabilizers — completely free of lead compounds. Safe for homes, schools, and hospitals. Meets international green building norms.

Zero Maintenance

Never needs painting, sanding, or chemical sealing. A simple wipe-down keeps GBT profiles looking brand-new for 15+ years of uninterrupted service.

Co-Extrusion Colour Technology

GBT's colour profiles are produced using advanced co-extrusion technology — the colour layer is molecularly bonded to the profile surface during manufacturing, not painted or coated after. The result is a finish that cannot peel, chip, or fade under UV exposure.
