Why Choose GBT

Key Advantages

Four Reasons GBT Profiles
Outperform the Rest

From raw compound to finished profile — every step in our process is designed to deliver measurable superiority.

01 — Precision

±0.2mm Dimensional Accuracy

Every profile is extruded with wall thickness tolerance held at ±0.2mm — tighter than industry standard. This ensures perfect system fit, smooth hardware operation, and structural integrity across all our 50mm to 112mm series without re-machining by fabricators.

02 — Technology

Co-Extrusion Colour Technology

Our colour profiles use advanced co-extrusion — colour is molecularly bonded into the surface layer during manufacturing, not painted on. The result is UV-stable, fade-proof, and scratch-resistant colour that lasts the full 15+ year service life without re-painting or maintenance.

03 — Safety

100% Lead-Free Formulation

GBT profiles use calcium-zinc stabilizers — completely free of lead compounds. This makes our profiles safe for homes, schools, and hospitals while meeting international green building standards.

04 — Quality

IS 12894 & ISO 9001 Certified

Our quality management system is certified to ISO 9001, and our profiles conform to IS 12894 — India's Bureau of Indian Standards specification for uPVC profiles. Every batch undergoes multi-point inspection covering dimensions, mass, straightness, colour gloss, and UV resistance before dispatch.

Quality Standards

Industry-Leading Precision

Every GBT profile is measured against the strictest dimensional, colour, and structural standards before leaving our facility.

Dimensions & Accuracy

Wall thickness tolerance of ±0.2mm verified at multiple checkpoints throughout the extrusion process — ensuring consistent system-ready profiles.

Colour & Gloss Standards

Co-extruded colour bonded at molecular level — UV-stabilized and tested for gloss consistency and 4000-hour weathering resistance.

Straightness

Profile bow, twist, and camber verified using calibrated checking jigs — maximum 2mm deviation per 3-metre length permitted.

Appearance & Profile Mass

Defect-free surface finish inspected visually at every run. Mass per metre verified to IS 12894 tolerances for guaranteed structural integrity.
