New material-selection evidence helps customers distinguish general-purpose isophthalic and higher-resistance vinyl ester GRP resin routes.
At a glance
- Use information for the exact product and project condition.
- Define loads, geometry, supports and exposure before ordering.
- Keep technical evidence, supply records and installation checks traceable.
Why this update matters
This update strengthens the route for GRP resin and corrosion selection. GRP Express is designed so that a customer can move from a product family to relevant engineering and installation information without mistaking general guidance for final project approval.
The product, its supports, fixings, environment and intended use form one system. Any safety-critical or regulated application still requires competent project-specific design and verification.
Define the requirement first
Record the function, dimensions, loads, support arrangement, interfaces and service environment. Include maintenance activity, contamination, weather and credible exceptional conditions. Identify required standards and evidence at the start.
For existing structures, use a controlled survey and one datum. Mark openings, edges, obstructions and tolerances. For new works, coordinate the GRP arrangement with the supporting design before dimensions are released.
| Decision area | Required input |
|---|---|
| Product | Exact family, depth or section, resin, surface and dimensions |
| Structure | Loads, span direction, support centres, bearing and deflection limit |
| Environment | Chemicals, temperature, moisture, UV, fire and electrical considerations |
| Installation | Cutting, fixings, access, tolerances, inspection and handover |
Apply evidence carefully
Use data that matches the exact configuration. Check units, test arrangement, span, support and acceptance criteria. Do not extend a result from one depth, resin or geometry to another without supporting evidence.
A certificate of conformity, declaration, test report and calculation each have a different purpose. Retain the relevant revision and link it to the product or project decision it supports.
Coordinate purchase and installation
Prepare one product schedule coordinated with current drawings and cut lists. Include identifiers, dimensions, quantities, finishes and compatible accessories. Confirm delivery access, unloading, storage and handling before dispatch.
Inspect supports and materials, trial-fit critical components and follow the applicable cutting and fixing guidance. Site changes should be reviewed and recorded rather than absorbed silently into the installation.
Inspection and lifecycle
Handover records should identify installed products, final details, inspections and relevant evidence. Cleaning and inspection guidance should reflect the actual exposure and use.
Review the system after changes to loading, openings, supports, chemicals, damage or use. Original product suitability cannot automatically cover a changed service condition.

Frequently asked questions
Does this information replace project design?
No. It supports product selection and coordination but does not replace competent design.
What details should a technical enquiry include?
Include application, dimensions, loads, supports, exposure, standards and required timing.
Should installation changes be recorded?
Yes. Changes to geometry, supports, fixings or product should be reviewed and included in the handover record.
