From design concept to finished planter — a detailed look at how Glastres Greens produces premium custom FRP planters at our Bengaluru factory.
Every custom FRP planter from Glastres Greens follows a rigorous, multi-stage manufacturing process designed to deliver structural integrity, surface quality and long-term durability. Our Bengaluru factory combines traditional hand-layup craftsmanship with modern quality control systems.
We work from architect drawings or create custom designs. High-quality moulds are produced to ensure dimensional accuracy and repeatable surface finish across production runs.
A minimum 15–20 MIL layer of UV-stabilized tooling gelcoat is applied to the mould. This becomes the durable, weather-resistant outer surface of the finished planter.
Multiple layers of fiberglass mat and resin are hand-laid to achieve the required wall thickness and structural strength while keeping weight to a minimum.
After curing, planters are carefully demoulded, trimmed, inspected and finished. Every planter undergoes quality control before packaging and dispatch.
We utilize high-grade isophthalic polyester resins rather than cheaper orthophthalic variants. This ensures superior resistance to water permeation, blistering, and chemical degradation from fertilizers, guaranteeing structural longevity.
Our in-house master pattern makers translate CAD drawings into physical molds with tolerances of ±2mm. This precision allows for flawless modular installations, ensuring continuous linear alignments in commercial spaces.
Beyond visual inspection, our structural lamination process is calibrated to meet strict flexural strength requirements (ASTM D790). Walls are engineered to resist root pressure expansion and immense hydrostatic soil loads.
We provide detailed process documentation and factory visit arrangements for large or custom projects.
