Understanding Warranty Terms by Material Grade
Poorna Enterprises distinguishes manufacturer material warranties from installation workmanship to provide complete transparency:
- Standard UV Nylon / HDPE Netting: Typically carries a manufacturer material warranty of up to 3 years against premature sunlight degradation under normal outdoor exposure.
- Garware Heavy-Duty UV Copolymer Nylon: Features high-tenacity multifilament twine with UV stabilizers, carrying a manufacturer material warranty of up to 5 years against UV degradation.
- Installation & Fixing Integrity: All stainless steel perimeter wire ropes, anchors, and tensioners are inspected, load-checked, and signed off with the building representative upon completion.
*Specific written warranty certificates are issued based on the exact material tier selected and documented in your on-site quotation.
What Influences Your Final Quotation?
- Shaft Accessibility & Working Height: Narrow, deep vertical shafts requiring technician descent via certified rope harnesses involve additional safety rigging compared to shallow, easily accessible lightwells.
- Structural Anchor Condition: Sound reinforced concrete beams provide straightforward anchor fixing, whereas weathered brickwork or plaster may require specialized chemical anchors or bracket supports.
- Service Access Hatches: Buildings with air conditioning condensers or plumbing valves inside the shaft require zippered openings so technicians can carry out repairs without cutting the net.
- RWA / Society Volume: Multi-block residential apartment associations covering multiple shafts benefit from grouped material optimization and reduced mobilization costs.
