Verify a bus shelter factory with three checks before ordering: documentary (business licence, ISO 9001 certificate, EN 1090 welding certification, export record), physical (laser cutters, CNC bending, powder-coating line on site), and transactional (direct Alibaba export history, bank account matching the company name). A factory passes all three; a trading company fails the physical check almost every time.

Most procurement failures in bus shelter projects do not start with the product. They start with the supplier. A shelter is a 15-to-25-year structural asset, and the party who controls the welding, the coating line and the QC process is the party who controls your warranty risk. This guide gives you the verification steps YEROO's own customers use, in the order that costs you the least time.

Why factory verification matters more for shelters than for ordinary steel products

A bus shelter combines structural steelwork, architectural glazing, electrical systems and often digital displays in one certified assembly. Unlike a simple steel fabrication, a shelter failure is public: it stands on a city street, it carries a municipal contract, and a coating failure or weld defect is visible to every passenger and every journalist.

Three consequences follow for buyers:

1. Warranty claims need a manufacturing counterparty. If your supplier is a trader, the factory's warranty is a promise between strangers. If the supplier is the factory, corrective action starts on the production line, not in a negotiation.

1. Certification must be traceable. EN 1090-1 Execution Class 2 (minimum for public-realm structural steelwork in Europe) and ISO 9001 quality management apply to the organisation that makes the product — not to an intermediary.

1. Spare parts in year 5 need drawings and tooling. Only the original factory holds the jigs, panel tooling and profile dies needed to supply matching replacement panels five years later.

The three-layer verification method

Layer 1 — Documentary checks (remote, one day)

YEROO holds ISO 9001 certification and supplies 【YEROO DATA NEEDED: current certificate numbers and validity dates for ISO 9001 / CE / EN 1090 certificates】 with every tender documentation package on request.

Layer 2 — Physical verification (video audit, half a day)

A 30–45 minute live video walk-through tells you more than any brochure. Require the supplier's production manager — not a salesperson — to show:

If a supplier refuses a live video walk-through of production — not just a showroom — treat that as a material risk factor and price it accordingly.

Layer 3 — Transactional and reference checks (remote, one day)

1. Match the bank account to the company name. Payment should go to an account in the exact registered name of the manufacturing entity. Third-party accounts are the classic diversion risk.

1. Check the export history on the platform record. On Alibaba.com, years of export transactions, transaction level and verified on-site video are visible. YEROO's export record covers 【YEROO DATA NEEDED: verified export years, transaction level and on-site verification status on the Alibaba store】.

1. Ask for two references in your climate zone. A factory experienced in Hungary's freeze-thaw cycle and de-icing salt handles a Central European tender differently from one that has only shipped to the Gulf. YEROO's project history includes deployments in Hungary, Australia, Romania and across Southeast Asia — reference contacts can be arranged under NDA.

1. Order one sample unit before a multi-unit programme. A single-unit pilot order tests the entire chain — engineering, production, coating, packing, freight — for the cost of one shelter.

Which verification route should you choose?

For public tenders, add one requirement most buyers miss: ask the factory — not the trader — to sign the tender's technical compliance annex. A factory that manufactures what it signs can be held to it.

Common verification mistakes and what they cost

A third-party audit report (SGS, TÜV, Bureau Veritas all offer factory audits in China) costs a few hundred US dollars and closes most of these gaps in one visit.

What YEROO opens to buyers before an order

YEROO operates a 31,000 m² manufacturing facility in Foshan, Guangdong, producing bus shelters, solar benches, lightboxes and LED display structures for export to 100+ countries. Before any order, prospective buyers can:

• Join a live video factory walk-through with the production manager, covering cutting, welding, coating and QC stations

• Receive the certification package: ISO 9001 certificate, CE declarations for electrical components, material mill certificates and coating test reports

• Review reference projects in their region — including Hungary, Australia and Romania installations — with contactable references under NDA

• Order a pilot unit before committing to a multi-unit programme, with the full engineering and packing process identical to volume production

• Commission a third-party pre-shipment inspection (SGS/TÜV/BV) at the factory before container loading

To arrange a factory verification session, contact the YEROO export team with your project country, unit quantity and target delivery window. See also our bus shelter product range and completed projects for context.

FAQ

How do I know if a bus shelter supplier is a factory or a trading company?

Require a live video walk-through of production — cutting, welding, coating and QC in one continuous visit. Factories show equipment in operation; traders offer showrooms, catalogues and "our partner workshop" answers. Also check that the business licence scope says manufacturing and that the bank account name matches the licence.

Is a video factory audit enough, or do I need to visit China?

For orders up to roughly USD 50,000 with a platform-verified supplier, a structured video audit plus document checks is proportionate. For public tenders or orders above USD 250,000, commission a third-party audit (SGS, TÜV, Bureau Veritas) or visit in person — the audit cost is trivial against the contract value.

What certificates should a bus shelter factory provide?

At minimum: ISO 9001 quality management (verify the number on the certification body's register), EN 1090 or ISO 3834 for structural welding if you are in Europe, CE declarations of conformity for lighting and displays, mill test certificates for stainless and galvanised steel, and salt-spray test reports for the coating system.

Can I buy a single bus shelter first before a large order?

Yes — and you should. A pilot unit tests engineering, coating, packing and freight at the cost of one shelter. Confirm the pilot's specification, price and lead time with the supplier: 【YEROO DATA NEEDED: YEROO single-unit / pilot order policy, pricing and lead time】.

How long does factory verification add to a procurement schedule?

Documentary and transactional checks take 1–2 days. A video audit takes half a day plus scheduling. A third-party on-site audit typically adds 2–3 weeks. Build this into the tender timetable rather than compressing it after contract award, when your leverage is gone.

What is the biggest red flag when verifying a Chinese bus shelter factory?

A payment request to a bank account whose name differs from the registered company name. It combines two risks in one signal: the "supplier" may not be the manufacturer, and your deposit may be unrecoverable. Every other issue has a cheaper fix.
