In 2019, Shanghai Qinkai Industrial Co., Ltd. took on the first order in its history worth more than 10 million yuan: the cable tray project at Hong Kong Airport, covering conduits, steel sections, custom components and accessories. The order was executed from a factory of 6,000 square metres.
Inside the company, the significance of that order has never been the value. It is the point at which a supplier found out whether it could carry a project of that size end to end — buying, fabricating, finishing, documenting and delivering — without a larger plant behind it.
What the order contained
1. Conduits. Mechanical protection and routing for cable as it crosses areas where access is controlled and open work is difficult. On an airport, conduit runs are planned around restricted zones and work windows rather than around the shortest path.
2. Steel sections. The load-bearing members that hold cable routes off the building structure. Airport work rarely starts from a clean frame: supports are frequently designed to fit existing structure, with the hole positions that follow from it.
3. Custom components. The parts that make a standard route suit a specific building — offsets, transitions, non-standard brackets and assemblies made to drawing.
4. Accessories. Fasteners, clamps and interface hardware that close the system up and keep it serviceable afterwards.
An airport does not buy a catalogue. What makes the scope work is the proportion of standard material to bespoke parts, and the drawing discipline that keeps the two consistent with each other.
Why an airport is a harder site than a greenfield plant
Airports do not close. Cable work is carried out inside a building that is handling passengers and aircraft movements on the same day, which changes almost every planning assumption. Access is scheduled and controlled. Work windows are short. Material has to move and be stored along defined routes. Any fire performance or material approval requirement has to be settled before the material is made, not when it reaches the gate.
Add a coastal, humid climate and a service life measured in decades, and the specification predictably leans on corrosion protection and on records that can still be read during an audit years later.
For a supplier, the practical consequence is that the order cannot be run as a production queue. It has to be run against a delivery schedule the site dictates.
What it took to hold an order that size together
On a first order of that value, the binding constraints are as much internal as technical. Material has to be committed and processed ahead of payment. Coating and finishing have to be batched to match the delivery windows the site can accept. Components have to be checked against drawings before a batch runs, not after it is packed. Every shipment has to carry the records the receiving end needs to verify what it has just been given.
From a 6,000-square-metre factory, that is a sequencing problem rather than a capacity problem: material in, work out, and no bay standing idle at the wrong moment.
What the order changed afterwards
“A first order of that size is not a sales result, it is a systems test,” the company said. “The drawing control, the batching, the finishing records, the packing schedule — all of that had to exist before the second order arrived. That is what 2019 actually produced.”
The product mix itself has not changed much since. Conduits, steel sections, custom components and accessories are still the backbone of the company’s project scopes, from photovoltaic plants to domestic thermal power work. What has changed is where the design happens and how the material is documented when it ships.
The airport has not stood still since
Hong Kong Airport has been in continuous development before and after the 2019 order. Its three-runway system was commissioned in November 2024 and is now in operation, according to ACI Asia-Pacific, and construction-phase environmental monitoring for the airport expansion was still being reported to Hong Kong’s Environmental Protection Department for the second quarter of 2026.
That is the environment this class of work lives in: an airport that is never closed, seldom finished, and rebuilt around its own operations while they continue.
