1. Transit Inspection & Acceptance

At SR POLYMERS, we take immense pride in our rotational molding craftsmanship and rigorous quality inspection. Because water storage tanks are bulky industrial goods, we strongly advise customers or their authorized site representatives to inspect the tanks thoroughly upon delivery from our transport vehicle.

2. Eligibility for Returns & Replacements

A return or free replacement is applicable strictly under the following circumstances:

  • Manufacturing Defects: Pinhole leaks, uneven wall thinness, or visible rotational molding flaws detected before plumbing installation.
  • Transit Damage: Significant structural denting or puncture incurred during vehicle transport by our factory freight service.
  • Incorrect Specification: Delivery of a capacity, layer configuration, or model different from the confirmed written order.

3. Reporting Window

Any transit damage or specification discrepancy must be noted on the delivery receipt and reported to our plant office within 48 hours of delivery. Photographic evidence of the issue must be shared with our team via WhatsApp (+91 91234 56789) or email (info@srpolymers.com).

4. Non-Returnable Scenarios

We cannot accept returns or provide refunds in the following cases:

  • The tank has already been drilled, cut, plumbed, or fitted with inlet/outlet brass adaptors.
  • Damage caused by dropping the tank during rooftop lifting, rough handling on site, or dragging across sharp gravel.
  • Tanks installed on an uneven, broken, or cantilevered platform causing hydrostatic deformation.
  • Change of mind regarding capacity or color after delivery has been completed in good condition.

5. Replacement & Refund Process

Upon verification of an eligible claim, SR POLYMERS will schedule a replacement tank on the next scheduled consignment to your district at zero additional freight charge. In the rare event that a replacement cannot be provided, a full refund will be processed via bank transfer within 5 to 7 working days.

ROTATIONAL MOLDING SPECIFICATION

Uniform Wall Thickness & Jointless Monolithic Shell

Our rotational molding manufacturing process ensures uniform wall thickness with zero joints or weld lines. Using 100% virgin food-grade polymer granules, expanded foam insulation, and carbon black UV barriers, each water tank is built for superior tensile strength, weather resistance, and hygienic drinking water storage across Bihar.

Zero Toxic Leaching UV Sun-Shield Layer Thermal Foam Core
100% Virgin Food-Grade Polymer

100% Virgin Food-Grade Polymer

Molded exclusively from pure virgin polymer granules with zero recycled scrap. Non-toxic, non-leaching inner surface keeps stored drinking water fresh, odorless, and pure.

Multi-Layer Thermal Shield

Multi-Layer Thermal Insulation

Engineered middle foam layer creates a thermal barrier that resists heat transfer, keeping stored water significantly cooler during extreme North Bihar summer heatwaves.

UV Sun-Shield Barrier

UV Sun-Shield & Algae Barrier

Outer layer enriched with high-grade UV stabilizers prevents plastic breakdown from direct sunlight exposure, while carbon black barrier blocks light to halt algae growth.

Heavy Duty Ribbed Wall Strength

Heavy-Duty Ribbed Wall Strength

Precision rotational molding ensures uniform wall thickness and circumferential reinforcement ribs for superior resistance against hydrostatic water pressure and wind.

Rotomolding Manufacturing & Purity Process

1

Raw Material Inspection

100% virgin food-grade polymer granules tested for density, melt flow index, and tensile strength.

2

Bi-Axial Rotational Molding

Multi-axis high-temperature rotational molding guarantees uniform wall distribution without weak seams.

3

Co-Extruded Multi-Layer Fusion

Distinct polymer layers (3 to 6 layers) fused molecularly to form an impenetrable, unified tank shell.

4

Quality & Hydrostatic Testing

Every batch undergoes drop impact, hydrostatic pressure, and wall thickness ultrasonic testing before dispatch.
