Quality Control

FRP quality problems are invisible at delivery and expensive at year three. Our QC system is designed around that fact — controlling the inputs and the process, because the finished panel cannot be non-destructively re-tested for resin type after it ships.

Incoming materials

  • Resin: every delivery verified against specification (acid value, viscosity, gel time) before release to production; resin lots traceable to panel batches
  • Glass: roving and mat certificates checked; moisture control on storage
  • Additives and pigments: per-batch records; UV package verified per formulation

In-process control

  • Glass content: monitored per batch against the panel specification (min. 25 % molded, min. 35 % bearing direction pultruded)
  • Cure verification: barcol hardness checks at defined intervals
  • Dimensional: mesh, depth and weight checked per production run against the nominal table

Panel verification

  • Panel-specific load tables prepared and signed for every quotation and order configuration
  • Periodic full-panel load testing correlating production panels to the published tables
  • Grit adhesion and COF checks on gritted-surface production

Pre-shipment

  • Visual inspection 100 %; dimensional sampling 10 %; weight sampling 5 %
  • Third-party inspection (SGS, BV or your nominated agency) available before shipment — witnessed sampling, load testing and documentation review
  • Documentation pack: mill certificates, load table, chemical confirmation, packing list with panel numbering
