Project spotlight

Haicang Aoguan Avenue, Xiamen

A sea crossing built almost entirely over tidal water. The photographs below are from our own site file: pile groups, Bailey trusses, ringlock along the edge, and the forms that cast the barrier plinth.

From the site

What the work actually looks like

No renders and no stock photography. These are the working levels, the pile heads and the edge details that decide whether a falsework package performs.

Manufacturing

Cut, fit, weld and coat under one roof

Our workshop runs plate cutting, fit-up, submerged-arc and CO₂ welding, CNC drilling and surface treatment in a single flow. That means the pile cap, the Bailey transom and the guardrail post on the same project share one welding procedure and one inspection standard.

WPS / PQR qualified welding, welder certificates on file
Dimensional check against the shop drawing before coating
Shot blast to Sa 2.5, then zinc-rich primer or hot-dip galvanising
Marking, bundle list and loading plan issued before shipment

Capability

Built for project schedules, not catalogue orders

Ask for a capacity sheet

01 / DRAWING FIRST

Shop drawings before steel

We return marked-up drawings with hole positions, splice details and camber within 3–5 working days, so the approval loop does not sit on the critical path.

02 / MIXED CONTAINERS

Four ranges, one container

Piles, panels, falsework and railing can be consolidated into a single shipment with one packing list — useful when a contractor sources the whole bridge package.
