Dock & Marine Hardware

Dock and marine hardware encompasses the structural steel components that make waterfront facilities functional - from dock frames and walkway supports to ladder components, railing systems, and equipment mounts. At Qingdao Tianhua Yihe Metal Fabrication (qdthyhmetalfab.com), we fabricate custom marine steel structures and hardware, all hot-dip galvanized to AS/NZS 4680 for corrosion resistance in splash zones, tidal areas, and salt spray environments.

Manufacturing Capabilities

Marine hardware fabrication combines standard structural steel techniques with special attention to weld quality and coating integrity. We ensure all welds are continuous and sealed to prevent crevice corrosion. Internal surfaces of hollow sections are fully galvanized. For critical applications, we can perform dye penetrant testing on welds before galvanizing.

Quality Assurance

Crevice corrosion prevention: continuous sealed welds, verified by visual inspection on 100% of parts

Internal coating verification on hollow sections (vent/drain holes placed before galvanizing)

Dye penetrant testing available on critical welds before coating

Material test certificates (MTC) provided with every shipment

ISO 9001:2015 certified quality management system

Frequently Asked Questions

Q: Can you fabricate complete dock frame assemblies?

A: Yes, we fabricate dock frames as sub-assemblies ready for site bolting. We can also pre-assemble in our factory for fit-up verification.

Q: How do you protect internal surfaces of hollow sections?

A: All hollow sections are fully galvanized inside and out. We ensure vent and drain holes are properly placed before galvanizing to achieve complete internal coating.

Q: Can you fabricate marine ladders and railings?

A: Yes, we fabricate marine ladders, railings, and walkway components from steel or stainless steel, all with appropriate corrosion protection.
