What inspections are carried out before FRP products leave the factory?
Routine inspection items include appearance quality, dimensional deviation, fiber content and mechanical properties.
Key products also undergo special tests such as corrosion testing and pressure testing.
Products leaving the factory generally come with inspection records or a certificate of conformity.
Batch products are sampled and tested by lot to keep quality consistent.
How should FRP products be inspected on delivery?
On acceptance, check the product specification, quantity and appearance quality, and look for defects such as cracks, blisters and delamination.
Dimensional deviation should meet the requirements of the contract or the relevant standard.
For important items, a third-party test report or on-site sampling can be requested.
Any problem found should be recorded promptly and taken up with the manufacturer.
How can I judge the quality of FRP products?
Surface finish, section density and fiber content give a direct indication, as good product has a flat surface and a dense section.
Ask the manufacturer for mechanical property data and raw material information to confirm that the resin system suits the service environment.
Sampling and testing a batch is an effective way to judge whether quality is stable.
A manufacturer with stable production capacity and a quality system gives more assurance.
Can FRP products be customized?
Yes. FRP products are mostly made in molds, so size, section and color can be customized to customer requirements.
Pultruded profiles can be made to a custom section shape, and wound products to a custom diameter and length.
For custom products, discuss process feasibility with the manufacturer in advance and confirm the lead time.
For custom batches, the tooling cost and lead time should be set out in the contract.
What is the usual delivery lead time for FRP products?
Standard sizes have a short delivery time, usually completing within one to several weeks.
Custom or large-volume orders take longer, since tooling and production scheduling are involved.
Plan the purchase in advance, confirm the exact lead time with the manufacturer and follow production progress.
Urgent orders can be discussed with the manufacturer for expedited scheduling, and some standard items can be supplied from stock.
What information do I need to provide when buying FRP products?
When buying, state the basic information: product type, size, quantity and service environment.
For corrosive environments, give the medium and its concentration so that the manufacturer can match the resin system.
For products with load requirements, provide the loads and support conditions so that selection can be calculated.
The more complete the information, the more accurate the technical proposal and quotation the manufacturer can give.
Do FRP products come with a warranty and after-sales service?
Reputable manufacturers generally provide a quality warranty for a set period and deal with quality problems that are not caused by human factors. The warranty scope and period should be set out in the contract, and for important products testing and claim clauses are advisable.
If a quality question arises during use, contact the manufacturer promptly and provide the product batch and service details so that it can be checked. Choosing a manufacturer with good after-sales service effectively reduces the risk of using the product after purchase.
What should I do if an FRP product has a quality problem?
If a quality problem is found, keep the product and its batch information and contact the manufacturer promptly with the details. Once the problem is verified, the manufacturer will deal with it as agreed in the contract, by supplying replacements, repairing the item or exchanging it. For important products with a safety implication, a third-party test can be requested to establish responsibility and protect your interests.
