Where the dock meets the deep.

Hot-dip galvanized and duplex hardware for piers, moorings, and offshore structures.

Container terminals, ferry berths, fuel piers, mooring dolphins, and offshore platforms. Marine infrastructure stands in the splash zone for fifty years — where coating thickness, duplex steel, and corrosion allowance decide whether the structure makes its service life.

Port cranes and pier infrastructure at the waterline

Industry Overview

Splash-zone hardware, specified to survive the tide line.

The splash zone is the most corrosive place on the planet for steel — wet, oxygenated, and loaded with chloride on every tide. Pier piles, fender systems, mooring hardware, and crane rails all live there, and the bolting has to last as long as the concrete around it.

We supply heavy hot-dip galvanized A325 and F1554 anchorage, 2205 duplex hardware for the worst exposure, and field-modifiable mooring and fender bolting — coated to spec, test-documented, and staged to the marine contractor’s pour and pile schedule.

Fasteners engineered for marine infrastructure.

Case Studies

Marine infrastructure fasteners at work.

Case 01

California port crane-rail anchor pour.

Problem

A California port expansion needed 800 hot-dip galvanized anchor bolts for ship-to-shore crane rails, with embedment templates staged to a tight pile-cap pour schedule.

Solution

We galvanized to F2329, assembled 800 anchor sets with templates and leveling nuts, and released them by pour sequence to match the marine contractor's plan.

Results

Every crane-rail pour landed on schedule with templates on site the morning each cap was poured.

“Anchor coordination usually sinks a marine pour schedule. This one never slipped.”

— Superintendent, California marine contractor

Case 02

California ferry-terminal fender replacement.

Problem

A California ferry terminal fender replacement needed duplex 2205 mooring hardware able to survive the splash zone, with field-adjustable lengths for as-built pile variation.

Solution

We supplied 2205 bolting with extra thread engagement and cut-to-length service at our facility for field re-orders inside 48 hours.

Results

The berth stayed in service through the replacement, with field re-cuts keeping the schedule through every as-built surprise.

“Duplex hardware, cut to length in two days, twice. That kept the ferries running.”

— Facilities Engineer, California ferry authority

Why California Fastener

Why California Fastener for marine infrastructure.

Marine civil work answers to the engineer of record and a fifty-year corrosion clock. We hot-dip to F2329, stock duplex for the splash zone, document every coating lot, and cut anchor rods to length in-house when the field never matches the drawing. Decades of pier, port, and offshore anchorage work means the bolting clears inspection and the pour schedule keeps moving.
