Technical Advantages

By utilizing high-strength steel chemistry and optimized weld geometries, our frames provide an exceptional strength-to-weight ratio that reduces overall logistics and handling costs. Every assembly undergoes strict non-destructive testing (NDT) to eliminate the risk of latent structural fatigue, extending operational asset life in harsh environments.

Having Doubts? Our FAQ

Can Frigate manufacture load-bearing frames based on our proprietary custom CAD designs?

Yes. We operate as a full-spec B2B manufacturing partner. Our engineering team conducts thorough Design for Manufacturability (DFM) reviews on your STEP, IGES, or DWG files to optimize weld paths, material utilization, and tolerances before production begins.

What quality documentation and certificates are provided with the delivery?

Every shipment includes a comprehensive manufacturing quality dossier. This package contains material test certificates (MTC Type 3.1), NDT inspection reports (Ultrasonic/Magnetic Particle), coating thickness validation logs, and final dimensional inspection reports.

How does Frigate mitigate structural distortion during the welding process?

We control weld distortion through specialized heavy-duty clamping fixtures, sequenced welding patterns, and strictly monitored heat-input parameters. For critical infrastructure components, post-weld heat treatment (PWHT) or stress-relieving options can be integrated.

What surface finish configurations do you offer for high-corrosion environments?

For aggressive environments (like coastal or chemical processing zones), we offer hot-dip galvanizing per ISO 1461, multi-coat polyurethane marine systems, or robust epoxy primers. These are designed to pass rigorous salt spray testing parameters based on your requirements.

How do you handle freight, logistics, and on-site delivery for oversized frames?

Frigate manages specialized logistics for heavy and over-dimensional cargo (ODC). We ensure all frames are structurally braced, securely padded, and tied down in dedicated flat-beds or low-bed trailers to preserve geometric tolerances during transit to your site.
