Zehao is a Tianjin-based metal bunk bed manufacturer supplying welded steel bunk beds factory-direct to dormitories, labour camps, prisons and student housing since 1999. Frames are SGS load-tested to 200 kg per tier (EN 747-1), certified to EN 747 / EN 1725 / CE / ISO 9001:2015, with MOQ from 50 sets and 25–30 day production lead time.
Why buy bunk beds factory-direct from a China manufacturer
Specifying bunk beds for a dormitory or project is a procurement decision, not a catalogue pick. Buying factory-direct from a manufacturer (rather than a trading company or a B2B marketplace listing) changes three things that decide the order:
- Transparent cost. No trading-company markup on the welded steel frame, powder-coat finish or KD packing.
- Documented quality system. ISO 9001:2015 management plus SGS load-test reports you can name the standard and berth on.
- Project delivery. Container loading plans, tender documentation (drawings, load-test reports, EN 747 certificates) and references across Africa, the Pacific, the Middle East and Europe.
- OEM / ODM. RAL colour, size, logo and structure to drawing or sample.

Dormitory & project bulk supply
For dormitory bunk bed projects, beds are specified by room, not by piece: measure floor area, ceiling height and door width, then decide berth count. Welded frames suit permanent installations; detachable frames suit temporary or reconfigurable sites. Mattresses, lockers and desks ship in the same container to avoid a second freight leg. A loading plan for 20GP and 40HQ is supplied with every quotation.
Australia supply & AS/NZS 4220:2026 compliance
Zehao supplies bunk beds to Australian camps, mining sites and student housing as a China-based manufacturer and exporter. Where the project requires it, beds are built and documented to AS/NZS 4220:2026 (Level 2) — Australia's mandatory bunk bed standard, which is not covered by EN 747. See the Australia AS/NZS 4220:2026 compliance page for the model ZE-A01-2301-AS specification (Ø42×1.0 mm posts, 300 mm guard rail, 2030×1070 mm footprint).
How to vet a bunk bed manufacturer
- Ask for the load-test report, not the certificate logo. It should name the standard (EN 747-1 or AS/NZS 4220) and the berth tested.
- Confirm an ISO 9001:2015 quality system and SGS load testing on file.
- Request project references with quantities (e.g. 1,050 triple bunks for a Malawi prison project, 1,500 anti-vandal bunks for a Guinea correctional project).
- Verify production capacity and a written delivery window tied to production, not just vessel availability.
Frequently asked questions
What should I check in a bunk bed manufacturer's load-test report?
The report should name the exact standard (EN 747-1 for general supply, AS/NZS 4220 for Australia) and the berth or tier it was tested on, with the load in kg. A certificate logo alone is not evidence — request the underlying SGS or equivalent test report.
What is the MOQ for a dormitory bunk bed project?
MOQ starts from 50 sets per model. Larger projects are quoted against a room schedule or berth count, and mixed models can share one container to cover a full range in a single shipment.
Do you supply AS/NZS 4220 bunk beds for Australia?
Yes. Zehao supplies AS/NZS 4220:2026 (Level 2) compliant bunk beds to Australian camps, mining and student-housing projects, built and documented to the Australian mandatory standard, which differs from EN 747.
Can a China bunk bed manufacturer handle a government tender?
Yes. Zehao provides tender documentation — drawings, load-test reports, EN 747 certificates and material certificates — plus citable project references across Africa, the Middle East, Europe and the Pacific.
What is the lead time for 500 bunk beds?
Standard items run 25–30 days after deposit confirmation. Custom sizes, finishes or compliance documentation are confirmed per order; a container loading plan is supplied with the quotation.
Do you provide OEM / ODM bunk beds?
Yes. RAL colour, size, logo and structure can be produced to drawing or sample. Mixed-model and mixed-container orders are accepted from 50 sets per model.
