Engineering note: this guide is general information, not project-specific structural design. Use current product data, the applicable code and the responsible engineer’s assessment.
Why a single online price is rarely useful
GFRP quotations depend on diameter, length, surface profile, resin and fibre system, straight or bent geometry, quantity, packaging, technical requirements, delivery location and programme. A published rate without those conditions can create the wrong budget expectation.
The Indian market also changes with raw materials, freight, taxes and project scale. SGF therefore does not present an unqualified universal rate. The cost calculator lets users enter current assumptions and see the basis of the result.
Do not compare composite and steel only per kilogram
Steel procurement is commonly discussed by weight. GFRP has a much lower density, so a kilogram buys a different running length. The better commercial comparison begins with the reinforcement schedule: total bar lengths, diameters, spacing, laps, shapes and wastage.
Convert both options into the quantities actually required by their respective engineering designs. Then compare delivered and installed scenarios. A cheaper rate can still produce a more expensive project if it ignores handling, protective systems, downtime or future repair; the reverse can also be true.
Inputs for an auditable cost model
Every estimate should display its assumptions so a quantity surveyor or engineer can change them. Keep structural design inputs separate from commercial inputs and clearly label any value that has not been verified.
- Element dimensions and reinforcement layout
- GFRP- and steel-specific bar schedules
- Bar lengths, laps, wastage and factory-made shapes
- Current supplier rates and tax basis
- Freight, unloading, storage and handling
- Installation productivity assumptions
- Protection, inspection and maintenance scenarios
From web estimate to quotation
Use the online calculator for an early scenario, not a purchase order. For a firm commercial response, send the latest drawings or BOQ, the required standards and documents, delivery location, phase-wise quantities and target programme.
A responsible quotation should identify inclusions, exclusions, validity, logistics, documentation and any technical point that needs confirmation. Project-specific engineering approval remains separate from the commercial estimate.
Technical references
Use the latest edition applicable to the project. External references are provided for engineering context.
