⚙️ Metal Bed Engineering & Tender Specifications
Download Spec (PDF / CAD) ➔| Static & Dynamic Load Capacity | Upper bunk 250 kg (550 lbs) static load; lower bunk 350 kg (770 lbs). Every frame is validated by dynamic impact and uniformly distributed load compression testing — no wobble, joint play or permanent deformation under heavy daily dormitory use. |
|---|---|
| Tube Dimensions & Wall Thickness | Standard 38×38 mm / 50×50 mm square tube, or Φ38 / Φ50 mm thickened cold-rolled round tube, with 1.2–1.5 mm wall thickness. Heavy-duty engineering upgrade to 2.0 mm wall available on request. |
| Guardrail Safety Standards | Full-perimeter raised guardrail on the upper bunk, height ≥ 300 mm and covering more than 80% of the bed length. Engineered to EN 747 / ASTM international fall-prevention and bunk-bed safety standards. |
| Squeak-Free Wedge-Lock Structure | Patented bolt-free wedge-lock / snap-fit connection: the heavier the load, the tighter the interlock. Zero clearance at every joint completely eliminates screw loosening and metal-on-metal noise — 100% squeak-free. |
| Ladder & Step Safety | Integrated widened anti-slip ladder (angled or vertical) with stamped anti-slip tread pattern, rounded corners to prevent knocks and bruises, and 250 mm step pitch for safe ergonomic climbing. |
| Steel Grade & Pre-treatment | Prime Q195 / Q235 high-strength cold-rolled structural steel tube, processed through fully automated shot-blasting plus 9-stage degreasing, acid pickling and ceramic conversion anti-corrosion pre-treatment. |
|---|---|
| Electrostatic Powder Coating | Eco-friendly epoxy-polyester electrostatic powder coating, 60–80 µm film thickness. Formaldehyde-free and odourless, scratch / acid / alkali resistant, and 48-hour salt-spray tested. |
| Bed Base & Slats Support | Densified all-steel square-tube bed base cross rails (or high-strength cold-drawn welded wire mesh). Mattress lays flat without a box spring, with breathable, moisture-resistant support that will not sag. |
| Knock-down Assembly & Flat Packing | Fully knock-down modular flat-pack design: 2 workers assemble one bunk bed in 10–15 minutes. Flat packing raises container loading efficiency by up to 300% versus assembled shipping. |
| Packaging & Standards Compliance | 5-ply export-grade corrugated carton with EPE foam edge and corner protection, fully compliant with the ISTA 3A drop-test standard for sea freight. Manufactured to ISO 9001 / ISO 14001 and school & camp tender requirements. |
❓ Procurement FAQ
Load ratings, squeak-free construction, guardrail compliance, tube gauges and flat-pack logistics — answered for school, camp and dormitory tenders.
What is the maximum weight capacity for the upper and lower bunks?
The upper bunk is rated at 250 kg (550 lbs) static load and the lower bunk at 350 kg (770 lbs). Every model is validated with dynamic impact testing and uniformly distributed load compression testing, so the frame keeps its geometry without wobble, joint play or permanent deformation under heavy daily dormitory use.
How does the snap-fit connection structure eliminate squeaking and wobbling?
Instead of relying on bolts that work loose, our patented wedge-lock / snap-fit joint drives a tapered wedge deeper into the post as load increases — the heavier the occupant, the tighter the interlock. With zero clearance at every joint there is no metal-on-metal friction, so the bed stays 100% squeak-free and wobble-free without periodic re-tightening.
Do your metal bunk beds comply with international safety standards for guardrails and ladders?
Yes. Upper bunks carry a full-perimeter guardrail at least 300 mm high covering more than 80% of the bed length, and ladders use stamped anti-slip treads with rounded corners and a 250 mm step pitch. Designs are engineered to EN 747 and ASTM bunk-bed safety requirements, and production runs under ISO 9001 and ISO 14001.
What steel pipe dimensions and wall thicknesses are used in production?
Standard frames use 38×38 mm or 50×50 mm square tube, or Φ38 / Φ50 mm cold-rolled round tube, in 1.2–1.5 mm wall thickness. For heavy-duty or tender specifications we upgrade to 2.0 mm wall thickness, and all steel is prime Q195 / Q235 cold-rolled structural grade.
How fast can a bunk bed be assembled, and what is the shipping packing volume?
Two workers can assemble one knock-down bunk bed in 10–15 minutes using the wedge-lock frame and supplied illustrated instructions — no welding or specialist tools required. Flat-packed cartons nest tightly, lifting container loading efficiency by up to 300% versus assembled shipping. Each carton is 5-ply export grade with EPE corner protection and is ISTA 3A drop-test compliant.
