If you specify bunk beds for dorms, prisons or camps, load capacity is the single most important safety number. This guide explains the European standards buyers ask about and how to verify a factory's claims.
EN 747: the bunk bed structural standard
EN 747 covers the safety, strength and durability of bunk beds and other raised beds. It defines test loads for the mattress base, guardrails and ladder, and sets limits on gaps that could trap a child or limb.
Buyers in Europe and many government tenders require EN 747 compliant bunk beds compliance. Ask for the test report, not just a self-declaration.
EN 1725: the bed frame and mattress standard
EN 1725 governs domestic bed frames and mattresses; its load and durability methods are often referenced alongside EN 747 for complete bed systems.
What 'SGS tested 200 kg' means
Zehao's welded steel bunks are SGS tested to 200 kg per berth by an independent lab. The certificate states the test method, sample size and the exact load held without deformation — keep it on file for tenders.
Reading a supplier's certificate
Check three things: the standard referenced (EN 747 vs a generic 'pass'), the per-berth figure, and whether it is dynamic (with impact) or only static. Dynamic rating is the honest number.
Frequently Asked Questions
Is EN 747 mandatory outside Europe?
Not legally, but many Middle East, African and Asian government tenders adopt it as the benchmark. Supplying a valid EN 747 report removes the biggest procurement objection.
Static vs dynamic load — which matters?
Dynamic (impact) load matters most for dorms and camps where beds take jumping and dropping. Zehao quotes dynamic per-berth ratings.
Can a 200 kg bed hold two adults?
Per berth, yes for sleeping load; do not exceed the rated load on a single level regardless of how many people.
