Frequently Asked Questions
1. How long does it take to receive non-stock fiberglass pultruded profiles in Canada?
Delivery time depends on whether the profile is stocked, manufactured to order, or requires new tooling. Canadian Composite Structures lists an estimated lead time of approximately 9–10 weeks for certain non-stock structural profiles, while standard stocked sizes may be available sooner. Custom production and overseas shipping can extend the total timeline. When comparing quotations, distinguish manufacturing lead time from transit time and confirm whether the quoted schedule includes fabrication, packaging, customs clearance, and delivery to your Canadian site.
2. How much does custom fiberglass pultrusion tooling cost?
Custom tooling costs depend on the profile cross-section, die complexity, dimensions, tolerances, and production requirements. A public composite-industry forum discussion has cited approximately US$6,000–40,000 for certain custom pultrusion dies, but this is an illustrative range rather than a verified Canadian market price. Request a separate quotation for tooling, sample production, and unit pricing, then compare the total cost at your expected order volume. For example, a US$6,000 die spread across 1,000 units adds US$6 per unit before other costs, whereas spreading the same fee across 10,000 units adds US$0.60 per unit.
3. How do I compare pultruded fiberglass grating load ratings for industrial walkways?
Compare grating depth, bearing-bar spacing, support span, load type, and allowable deflection using the manufacturer's load table for the exact product. Do not assume that two grating panels with the same thickness have the same load capacity. For example, a panel spanning 1,000 mm may behave differently from the same panel spanning 1,500 mm, even under the same applied load. Confirm the design load, concentrated-load requirements, deflection limit, support arrangement, and relevant safety factors with the manufacturer or project engineer before specifying the grating.
4. Should I choose polyester or vinyl ester resin for fiberglass profiles used in wastewater treatment?
The choice depends on the wastewater chemistry, chemical concentration, operating temperature, exposure duration, and cleaning process. Polyester resin may be suitable for many general industrial environments, while vinyl ester is often considered for more aggressive chemical exposure. However, neither resin should be assumed suitable for every wastewater application. Provide the manufacturer with the chemical names, concentrations, and maximum operating temperatures, and request a chemical-resistance assessment for the specific resin formulation. Also confirm whether the profile uses a protective surface veil and whether the supporting compatibility data covers continuous exposure rather than occasional contact.
5. Can I order a small quantity of custom fiberglass pultruded profiles without paying for a new die?
Possibly, if the manufacturer already has a compatible die or can supply a standard profile that meets your dimensional requirements. A completely new cross-section typically requires dedicated tooling, making small orders more expensive on a per-unit basis. Ask whether an existing die can be adapted, whether standard profiles can be cut to length, and whether the manufacturer offers prototype quantities. Compare the total cost of standard-profile modification against custom tooling, including machining, cutting waste, and minimum order quantities, before choosing a production route.
