- Clear Span: 24m
- Eave Height: 10m
- Main Frame: Q355B Steel with enhanced corrosion protection

- Design Wind Load: 2.0 kN/m² (hurricane-resistant)
- Completion Time: 5 months from order to handover
Project Challenges & Our Solutions
During the execution of this project, we encountered several unique challenges specific to the Bahamas market. Our experienced team developed targeted solutions to ensure the project’s success:
Challenge 1: Extreme Hurricane Wind Requirements
Problem: Being within the High-Risk Wind Zone of the Bahamas, the hurricane wind can get up to 250 kph in nature. One requirement for the building code is that a wind load of 2.0 kN/m2 be used which is considerably higher than that of our typical design.
Our Solution：
- Redesigned the main frame with thicker steel sections and additional bracing
- Implemented a reinforced standing seam roof system with mechanical fastening
- Added extra anchor bolts to securely connect the structure to the foundation
- Conducted wind tunnel testing to verify the design’s performance
Challenge 2: Severe Corrosion from Saltwater Environment
The coastal location of Nassau means that there is high humidity and a high concentration of salt in the air, which results in rapid corrosion of steel structures.
Our Solution:
- Upgraded the surface treatment to a 3-layer system: SA2.5 sandblasting + 80μm zinc-rich epoxy primer + 100μm polyurethane topcoat
- Used galvanized steel for all secondary components and fasteners
- Applied additional corrosion protection to all connection points
- Provided the client with a detailed maintenance schedule to extend the building’s lifespan
Challenge 3: Complex Logistics and Customs Clearance
Problem: Because the Bahamas is island-based, it has few shipping options and rigid customs rules. Therefore, there were possible delays in getting the containers delivered or cleared.
Our Solution:
- Optimized container loading to maximize space utilization and reduce shipping costs
- Prepared all necessary documentation in advance, including structural calculations and compliance certificates
- Partnered with a local logistics company with expertise in Bahamian customs
- Coordinated closely with the port authorities to ensure smooth unloading and transportation
Challenge 4: Limited Local Construction Expertise
The local construction team didn’t really know how to build the metal building that they ordered so they were going to have trouble building it right and it would also be delayed getting done.
Our Solution:
- Sent 2 senior installation supervisors to the site for the entire construction period
- Provided detailed 3D installation drawings and video tutorials
- Conducted daily training sessions for the local workers
- Implemented a step-by-step quality inspection process to ensure compliance with our standards
Construction Process
Our 5-month construction process was carefully planned to overcome the unique challenges of this project:
Phase 1: Design & Engineering (Weeks 1-4)
- Conducted site assessment and soil testing
- Developed custom design to meet hurricane and corrosion requirements
- Obtained all necessary approvals from local authorities
- Finalized structural calculations and shop drawings
Phase 2: Factory Fabrication (Weeks 5-10)
- CNC cutting, drilling, and bending of all steel components
- Advanced corrosion protection treatment
- Pre-assembly inspection to ensure perfect fit
- Careful packaging and container loading
Phase 3: Shipping & Site Preparation (Weeks 11-14)
- Ocean freight from China to Nassau
- Parallel foundation construction by local contractors
- Site preparation and material storage
- Customs clearance and delivery to the site
Phase 4: On-Site Installation (Weeks 15-20)
- Main frame erection
- Secondary structure installation
- Roof and wall cladding
- Doors, windows, and accessories
- Final inspection and handover
Project Gallery

- Internal view reveals the building’s clear-span construction and its natural light system.
- The roof structure has been reinforced to withstand the high wind speeds produced by hurricanes.
- Local Construction workers are busy casting the floor slab, as we continue to provide guidance to them.
Project Highlights
- Tornado Resistant Structure: Constructed to resist the forces of winds up to 250 km/h.
- Highly Resilient Coating: The building is coated with an advanced coating that will protect it against corrosion in high-salt environments for many years.
- The structure design allows a lot of daylight to pass through the windows and are constructed with a translucent roof which reduces the energy required to illuminate the building by 30%.
- Construction was completed in less than five months (i.e., twenty-two weeks), and was completed two weeks before the original estimated completion date.
- The building layout design is custom-tailored to meet the client’s specific production requirements.
- The building and all construction practices satisfy all Bahamian building standards and building code requirements.
Client Testimonial
Our experience with BINGFA Steel on the factory project in Nassau, Bahamas was excellent. The company recognised the special challenges that come with building in the Bahamas and found new ways to solve every issue that we faced. The team at BINGFA Steel were very professional, very knowledgeable and always available to answer any of our questions. We finished the factory ahead of schedule and it did not only meet our expectations but it exceeded our expectations in terms of quality and performance. We would really recommend BINGFA Steel to anyone in need of a pre-engineered steel building manufacturer they can depend on.
