Industry Applications

Highway & Railway Bridges

Engineered to bear continuous dynamic stresses and heavy rolling loads. They provide structural stability for long-span overpasses and high-speed rail networks.

Industrial Warehouses

Ideal for massive clear-span logistics hubs and manufacturing facilities. These girders eliminate intermediate columns to maximize usable floor space.

Metro Elevated Corridors

Custom-curved and fabricated to support heavy mass transit rail tracks. They ensure minimal deflection and strict compliance with urban safety standards.

Heavy Overhead Crane Runways

Designed to withstand severe cyclic wheel loads and high torque forces. They provide a rigid, reliable track framework for heavy-duty industrial EOT cranes.

High-Rise Commercial Buildings

Acts as the primary load-bearing matrix for multi-story steel structures. They efficiently transfer vertical and lateral wind loads to foundations.

Power Plants & Refineries

Heavy structural framing capable of supporting massive process equipment, cooling towers, and high-temperature piping manifolds under extreme conditions.

Having Doubts? Our FAQ

Can Frigate customize girder profiles based on project-specific Finite Element Analysis (FEA) models?

Yes. Our engineering team reviews your design packages, structural parameters, and FEA data to fabricate custom built-up plates and tailored beam sections that perfectly match your exact load requirements.

What quality documentation and certifications accompany each batch of support girders?

We provide comprehensive Quality Assurance Books including Mill Test Certificates (MTC), NDT reports (Ultrasonic and Radiography tests), blasting profile proofs, coating thickness (DFT) logs, and final dimensional inspection reports.

How does Frigate optimize the total cost of ownership (TCO) and lead times for large structural rollouts?

Through our strong strategic sourcing network for raw steel plates and automated high-efficiency welding lines, we minimize material wastage, secure volume discounts, and compress production cycles to ensure highly predictable lead times.

Do you offer specialized anti-corrosive coatings for girders deployed in coastal or high-humidity environments?

Absolutely. We offer heavy-duty surface protections including hot-dip galvanization, multi-coat epoxy systems, and marine-grade polyurethane coatings designed to withstand aggressive atmospheric corrosion class C4 and C5 environments.

What are your shipping and logistics capabilities for handling over-dimensional cargo (ODC)?

Frigate manages complete logistics for oversized, heavy-built girders. We handle everything from specialized multi-axle trailers and transport routing permissions to ensuring secure tie-downs, preventing structural warping during transit.
