Having Doubts? Our FAQ

How do Frigate’s modular structural sections reduce total project lead times?

Because our structural sections are pre-engineered, cut, and drilled to precise tolerances at our manufacturing facilities, they arrive on-site ready for immediate assembly. This plug-and-play bolting method eliminates time-consuming field fabrication, on-site welding delays, and expensive inspection protocols, accelerating your structural commissioning phase.

Can these structural sections be customized to specific engineering design files?

Absolutely. We work directly with your engineering team to fabricate sections based on your custom structural drawings, specific connection details, or unique geometric requirements. Our manufacturing setup accommodates non-standard section depths, customized hole patterns, and specialized heavy-duty connection plates.

What corrosion protection options do you provide for harsh industrial environments?

To combat aggressive industrial or marine environments, we offer heavy-duty hot-dip galvanization conforming to ISO 1461, delivering zinc coatings from 85 μm to over 100 μm. Alternatively, we can provide multi-coat epoxy primer and polyurethane topcoat paint systems tailored to specific C4 or C5 corrosion categories.

What quality compliance certifications do you provide with each shipment?

Every batch of structural sections leaves our facility with a comprehensive quality assurance documentation pack. This includes Mill Test Certificates (MTC) tracking material traceability to IS or ASTM standards, Non-Destructive Testing (NDT) reports for welds, galvanizing thickness reports, and dimensional compliance certificates.

How do you handle shipping logistics and site delivery sequence for bulk orders?

We coordinate with your project planning team to stagger shipments based on your on-site erection sequence (e.g., foundation beams arriving before secondary bracing). All modular elements are clearly labeled and bundled according to structural sub-assemblies, minimizing sorting confusion and handling time upon delivery.
